This time David Chalmers brought the Meta-problem of Consciousness into the overall conversation by making a presentation about his paper on the topic. I think that this was a great addition to the conference, and it played beautifully as a tone-setter.
“The meta-problem of consciousness is (to a first approximation) the problem of explaining why we think that there is a problem of consciousness.”
And of all of his works, I would argue, discussing the meta-problem of consciousness is perhaps one of the things that will help advance the field of consciousness research the most. In brief, we are in sore need of an agreed-upon explanation for the reasons why consciousness poses a problem at all. Rather than getting caught up in unfruitful arguments at the top of the argumentative tree, it is helpful to sometimes be directed to look at the roots of people’s divergent intuitions. This tends to highlight unexpected differences in people’s philosophical background assumptions.
And the fact that these background assumptions are often not specified leads to problems. For example: talking past each other due to differences in terminology, people attacking a chain of reasoning when in fact their disagreement starts at the level of ontology, and failure to recognize and map useful argumentative isomorphisms from one ontology onto another.
Having the Meta-Problem of Consciousness at the forefront of the discussions, in my appraisal of the event, turned out to be very generative. Asking an epiphenomenalist, an eliminativist, a panprotopsychist, etc. to explain why they think their view is true seemed less helpful in advancing the state of our collective knowledge than asking them about their thoughts on the Meta-Problem of Consciousness.
(2) Qualia Formalism in the Water Supply
At the Qualia Research Institute we explicitly assume that consciousness is not only real, but that it is formalizable. This is not a high-level claim about the fact that we can come up with a precise vocabulary to talk about consciousness. It is a radical take on the degree to which formal mathematical models of experience can be discovered. Qualia Formalism, as we define it, is the claim that for any conscious experience, there exists a mathematical object whose properties are isomorphic to the phenomenology of that experience. Anti-formalists, on the other hand, might say that consciousness is an improper reification.
For formalists, consciousness is akin to electromagnetism: we started out with a series of peculiar disparate phenomena such as lightning, electricity, magnets, static-electricity, etc. After a lot of work, it turned out that all of these diverse phenomena had a crisp unifying mathematical underpinning. More so, this formalism was not merely descriptive. Light, among other phenomena, were hidden in it. That is, finding a mathematical formalism for real phenomena can be generalizable to even more domains, be strongly informative for ontology, and ultimately, also technologically generative (the computer you are using to read this article wouldn’t- and in fact couldn’t -exist if electromagnetism wasn’t formalizable).
For anti-formalists, consciousness is akin to Élan vital. People had formed the incorrect impression that explaining life necessitated a new ontology. That life was, in some sense, (much) more than just the sum of life-less forces in complex arrangements. And in order to account for the diverse (apparently unphysical) behaviors of life, we needed a life force. Yet no matter how hard biologists, chemists, and physicists have tried to look for it, no life force has been found. As of 2018 it is widely agreed by scientists that life can be reduced to complex biochemical interactions. In the same vein, anti-formalists about consciousness would argue that people are making a category error when they try to explain consciousness itself. Consciousness will go the same way as Élan vital: it will turn out to be an improper reification.
In particular, the new concept-handle on the block to refer to anti-formalist views of consciousness is “illusionism”. Chalmers writes on The Meta-Problem of Consciousness:
This strategy [of talking about the meta-problem] typically involves what Keith Frankish has called illusionism about consciousness: the view that consciousness is or involves a sort of introspective illusion. Frankish calls the problem of explaining the illusion of consciousness the illusion problem. The illusion problem is a close relative of the meta-problem: it is the version of the meta-problem that arises if one adds the thesis that consciousness is an illusion. Illusionists (who include philosophers such as Daniel Dennett, Frankish, and Derk Pereboom, and scientists such as Michael Graziano and Nicholas Humphrey) typically hold that a solution to the meta-problem will itself solve or dissolve the hard problem.
In the broader academic domain, it seems that most scientists and philosophers are neither explicitly formalists nor anti-formalists. The problem is, this question has not been widely discussed. We at QRI believe that there is a fork in the road ahead of us. That while both formalist and anti-formalist views are defensible, there is very little room in-between for coherent theories of consciousness. The problem of whether qualia formalism is correct or not is what Michael Johnson has coined as TheReal Problem of Consciousness. Solving it would lead to radical improvements in our understanding of consciousness.
What a hypothetical eliminativist about consciousness would say to my colleague Michael Johnson in response to the question – “so you think consciousness is just a bag of tricks?”: No, consciousness is not a bag of tricks. It’s an illusion, Michael. A trick is what a Convolutional Neural Network needs to do to perform well on a text classification task. The illusion of consciousness is the radical ontological obfuscation that your brain performs in order to render its internal attentional dynamics as a helpful user-interface that even a kid can utilize for thinking.
Now, largely thanks to the fact that Integrated Information Theory (IIT) is being discussed openly, qualia formalism is (implicitly) starting to have its turn on the table. While we believe that IIT does not work out as a complete account of consciousness for a variety of reasons (our full critique of it is certainly over-due), we do strongly agree with its formalist take on consciousness. In fact, IIT might be the only mainstream theory of consciousness that assumes anything resembling qualia formalism. So its introduction into the water supply (so to speak) has given a lot of people the chance to ponder whether consciousness has a formal structure.
(3) Great New Psychedelic Research
The conference featured the amazing research of Robin Carhart-Harris, Anil K. Seth, and Selen Atasoy, all of whom are advancing the frontier of consciousness research by virtue of collecting new data, generating computational models to explain it, and developing big-picture accounts of psychedelic action. We’ve already featured Atasoy’s work in here. Her method of decomposing brain activity into harmonics is perhaps one of the most promising avenues for advancing qualia formalist accounts of consciousness (i.e. tentative data-structures in which the information about a given conscious state is encoded). Robin’s entropic brain theory is, we believe, a really good step in the right direction, and we hope to formalize how valence enters the picture in the future (especially as it pertains to being able to explain qualia annealingon psychedelic states). Finally, Anil is steel-manning the case for predictive coding’s role in psychedelic action, and, intriguingly, also advancing the field by trying to find out in exactly what ways the effects of psychedelics can be simulated with VR and strobe lights (cf. Algorithmic Reduction of Psychedelic States, and Getting Closer to Digital LSD).
(4) Superb Aesthetic
The Science of Consciousness brings together a group of people with eclectic takes on reality, extremely high Openness to Experience, uncompromising curiosity about consciousness, and wide-ranging academic backgrounds, and this results in an amazing aesthetic. In 2016 the underlying tone was set by Dorian Electra and Baba Brinkman, who contributed with consciousness-focused music and witty comedy (we need more of that kind of thing in the world). Dorian Electra even released an album titled “Magical Consciousness Conference” which discusses in a musical format classical topics of philosophy of mind such as: the mind-body problem, brains in vats, and the Chinese Room.
The Science of Consciousness conference carries a timeless aesthetic that is hard to describe. If I were forced to put a label on it, I would say it is qualia-aware paranormal-adjacentpsychedelicmeta-cognitivefuturism, or something along those lines. For instance, see how you can spot philosophers of all ages vigorously dancing to the empiricists vs. rationalists song by Dorian Electra (featuring David Chalmers) at The End of Consciousness Party in this video. Yes, that’s the vibe of this conference. The conference also has a Poetry Slam on Friday in which people read poems about qualia, the binding problem, and psychedelics (this year I performed a philosophy of mind stand-up comedy sketch there). They also play the Zombie Blues that night, in which people take turns to sing about philosophical zombies. Here are some of Chalmers’ verses:
I act like you act
I do what you do
But I don’t know
What it’s like to be you
What consciousness is!
I ain’t got a clue
I got the Zombie Blues!!!
I asked Tononi:
“How conscious am I?”
He said “Let’s see…”
“I’ll measure your Phi”
He said “Oh Dear!”
“It’s zero for you!”
And that’s why you’ve got the Zombie Blues!!!
Noteworthy too is the presence of after-parties that end at 3AM, the liberal attitude on cannabis, and the crazy DMT art featured in the lobby. Here are some pictures we took late at night borrowing some awesome signs we found at a Quantum Healing stand.
Panpsychism Made Practical
No Zombies Allowed: Human or Zombie? Get Tested Here
(5) We found a number of QRI allies and supporters
Finally, we were very pleased to find that Qualia Computing readers and QRI supporters attended the conference. We also made some good new friends along the way, and on the whole we judged the conference to be very much worth our time. For example, we were happy to meet Link Swanson, who recently published his article titled Unifying Theories of Psychedelic Drug Effects. I in fact had read this article a week before the event and thought it was great. I was planning on emailing him after the conference, and I was pleasantly surprised to meet him in person there instead. If you met us at the conference, thanks for coming up and saying hi! Also, thank you to all who organized or ran the conference, and to all who attended it!
QRI members, friends, and allies
What I Would Like to See More Of
(1) Qualia Formalism
We hope and anticipate that in future years the field of consciousness research will experience an interesting process in which theory proponents will come out as either formalists or anti-formalists. In the meantime, we would love to see more people at least taking seriously the vision of qualia formalism. One of the things we asked ourselves during the conference was: “Where can we find other formalists?”. Perhaps the best heuristic we explored was the simple strategy of going to the most relevant concurrent sessions (e.g. physics and consciousness, and fundamental theories of consciousness). Interestingly, the people who had more formalist intuitions also tended to take IIT seriously.
(2) Explicit Talk About Valence (and Reducing Suffering)
To our knowledge, our talks were the only ones in the event that directly addressed valence (i.e. the pleasure-pain axis). I wish there were more, given the paramount importance of affect in the brain’s computational processing, its role in culture, and of course, its ethical relevance. What is the point of meaning and intelligence if one cannot be happy?
Related to (2), we think that one of the most important barriers for making progress in valence research is the fact that most people (even neuroscientists and philosophers of mind) think of it as a very personal thing with no underlying reality beyond hearsay or opinion. Some people like ice-cream, some like salads. Some people like Pink Floyd, others like Katy Perry. So why should we think that there is a unifying equation for bliss? Well, in our view, nobody actually likes ice-cream or Pink Floyd. Rather, ice-cream and Pink Floyd trigger high-valence states, and it is the high valence states that are actually liked and valuable. Our minds are constructed in such a way that we project pleasure and pain out into the world and think of them as necessarily connected to the external state of affairs. But this, we argue, is indeed an illusion (unlike qualia, which is as real as it gets).
Even the people in the Artificial Intelligence and Machine Consciousness plenary panel seemed subject to the Tyranny of the Intentional Object. During the Q&A section I asked them: “if you were given a billion dollars to build a brain or machine that could experience super-happiness, how would you go about doing so?” Their response was that happiness/bliss only makes sense in relational terms (i.e. by interacting with others in the real world). Someone even said that “dopamine in the brain is just superficial happiness… authentic happiness requires you to gain meaning from what you do in the world.” This is a common view to take, but I would also point out that if it is possible to generate valence in artificial minds without human interactions, generating high valence could be done more directly. Finding methods to modulate valence would be done more efficiently by seeking out foundational qualia formalist accounts of valence.
(4) Bigger Role for the Combination Problem
The number of people who account for the binding problem (also called the combination or boundary problem) is vanishingly small. How and why consciousness appears as unitary is a deep philosophical problem that cannot be dismissed with simple appeals to illusionism or implicit information processing. In general, my sense has been that many neuroscientists, computer scientists, and philosophers of mind don’t spend much time thinking about the binding problem. I have planned an article that will go in depth about why it might be that people don’t take this problem more seriously. As David Pearce has eloquently argued, any scientific theory of consciousness has to explain the binding problem. Nowadays, almost no one addresses it (and much less compellingly provides any plausible solution to it). The conference did have one concurrent session called “Panpsychism and the Combination Problem” (which I couldn’t attend), and a few more people I interacted with seemed to care about it, but the proportion was very small.
(5) Bumping-up the Effect Size of Psi Phenomena (if they are real)
There is a significant amount of interest in Psi (parapsychology) from people attending this conference. I myself am agnostic about the matter. The Institute of Noetic Science (IONS) conducts interesting research in this area, and there are some studies that argue that publication bias cannot explain the effects observed. I am not convinced that other explanations have been ruled out, but I am sympathetic to people who try to study weird phenomena within a serious scientific framework (as you might tell from this article). What puzzles me is why there aren’t more people advocating for increasing the effect size of these effects in order to study them. Some data suggests that Psi (in the form of telepathy) is stronger with twins, meditators, people on psychedelics, and people who believe in Psi. But even then the effect sizes reported are tiny. Why not go all-in and try to max out the effect size by combining these features? I.e. why not conduct studies with twins who claim to have had psychic experiences, who meditate a lot, and who can handle high doses of LSD and ketamine in sensory deprivation tanks? If we could bump up the effect sizes far enough, maybe we could definitively settle the matter.
(6) And why not… also a lab component?
Finally, I think that trip reports by philosophically-literate cognitive scientists are much more valuable than trip reports by the average Joe. I would love to see a practical component to the conference someday. The sort of thing that would lead to publications like: “The Phenomenology of Candy-Flipping: An Empirical First-Person Investigation with Philosophers of Mind at a Consciousness Conference.”
The Cards and Deck Types of Consciousness Theories
To make the analogy between Magic decks and theories of consciousness, we need to find a suitable interpretation for a card. In this case, I would posit that cards can be interpreted as either background assumptions, required criteria, emphasized empirical findings, and interpretations of phenomena. Let’s call these, generally, components of a theory.
Like we see in Magic, we will also find that some components support each other while others interact neutrally or mutually exclude each other. For example, if one’s theory of consciousness explicitly rejects the notion that quantum mechanics influences consciousness, then it is irrelevant whether one also postulates that the Copenhagen interpretation of quantum mechanics is correct. On the other hand, if one identifies the locus of consciousness to be in the microtubules inside pyramidal cells, then the particular interpretation of quantum mechanics one has is of paramount importance.
Consciousness as the Result of Action-Oriented Cognition (not explicitly named)
Higher Order Thought Theory (HOT)
So how has the meta-game changed since then? Based on the plenary presentations, the concurrent sessions, the workshops, the posters, and my conversations with many of the participants, I’d say (without much objective proof) that the new meta-game now looks more or less like this:
Orchestrated Objective Reduction (Orch OR)
Integrated Information Theory (IIT)
Entropic Brain Theory (EBT)
Global Neuronal Workspace Theory (GNWS)
Prediction Error Minimization (PEM)
Panprotopsychist as a General Framework
Harmonic-Resonant Theories of Consciousness
It seems that Higher Order Thought (HOT) theories of consciousness have fallen out of favor. Additionally, we have a new contender on the table: Harmonic-Resonant Theories of Consciousness is now slowly climbing up the list (which, it turns out, had already been in the water supply since 2006 when Steven Lehar attended the conference, but only now is gathering popular support).
Given the general telos of the conference, it is not surprising that deflationary theories of consciousness do not seem to have a strong representation. I found a few people here and there who would identify as illusionists, but there were not enough to deserve their place in a short-list of dominant deck types. I assume it would be rather unpleasant for people with this general view about consciousness to hang out with so many consciousness realists.
A good number of people I talked to admitted that they didn’t understand IIT, but that they nonetheless felt that something along the lines of irreducible causality was probably a big part of the explanation for consciousness. In contrast, we also saw a few interesting reactions to IIT – some people said “I hate IIT” and “don’t get me started on IIT”. It is unclear what is causing such reactions, but they are worth noting. Is this an allergic reaction to qualia formalism? We don’t have enough information at the moment to know.
The spiritual side of consciousness research is liable to overfocus on ethics and mood hacks rather than on truth-seeking. The problem is that a lot of people have emotionally load-bearing beliefs and points of view connected to how they see reality’s big plot. This is a generalized phenomenon, but its highest expression is found within spiritually-focused thinkers. Many of them come across as evangelizers rather than philosophers, scientists, explorers, or educators. For example: two years ago, David Pearce and I had an uncomfortable conversation with a lady who had a very negative reaction to Pearce’s take on suffering (i.e. that we should use biotechnology to eradicate it). She insisted suffering was part of life and that bliss can’t exist without it (a common argument for sure, but the problem was the intense emotional reaction and insistence on continuing the conversation until we had changed our minds).
We learned our lesson – if you suspect that a person has emotionally load-bearing beliefs about a grand plan or big spiritual telos, don’t mention you are trying to reduce suffering with biotechnology. It’s a gamble, and the chance for a pleasant interaction and meaningful exchange of ideas is not worth the risk of interpersonal friction, time investment, and the pointlessness of a potential ensuing heated discussion.
This brings me to an important matter…
Who are the people who are providing genuinely new contributions to the conversation?
There is a lot of noise in the field of consciousness research. Understandably, a lot of people react to this state of affairs with generalized skepticism (and even cynicism). In my experience, if you approach a neuroscientist in order to discuss consciousness, she will usually choose to simply listen to her priors rather than to you (no matter how philosophically rigorous and scientifically literate you may be).
And yet, at this conference and many other places, there are indeed a lot of people who have something new and valuable to contribute to our understanding of consciousness. So who are they? What allows a person to make a novel contribution?
I would suggest that people who fall into one of the following four categories have a higher chance of this:
People who have new information
Highly creative people with broad knowledge of the field
New paradigm proposers
For (1): This can take one of three forms: (a) New information about phenomenology (i.e. rational psychonauts with strong interpretation and synthesis skills). (b) New third-person data (i.e. as provided by scientists who conduct new research on e.g. neuroimaging). And (c) new information on how to map third-person data to phenomenology, especially about rare states of consciousness (i.e. as obtained from people who have both access to third-person data sources and excellent experienced phenomenologists). (a) Is very hard to come by because most psychonauts and meditators fall for one or more traps (e.g. believing in the tyranny of the intentional object, being direct realists, being dogmatic about a given pre-scientific metaphysic, etc.). (b) Is constrained by the number of labs and the current Kuhnian paradigms within which they work. And (c) is not only rare, but currently nonexistent. Hence, there are necessarily few people who can contribute to the broader conversation about consciousness by bringing new information to the table.
For (2): Great synthesizers are hard to come by. They do not need to generate new paradigms or have new information. What they have is the key ability to find what the novel contribution in a given proposal is. They gather what is similar and different across paradigms, and make effective lossless compressions – saving us all valuable time, reducing confusion, and facilitating the cross-pollination between various disciplines and paradigms. This requires the ability to extract what matters from large volumes of extremely detailed and paradigm-specific literature. Hence, it is also rare to find great synthesizers.
For (3): Being able to pose new questions, and generate weird but not random hypotheses can often be very useful. Likewise, being able to think of completely outrageous outside-the-box views might be key for advancing our understanding of consciousness. That said, non-philosophers tend to underestimate just how weird an observation about consciousness needs to be for it to be new. This in practice constrains the range of people able to contribute in this way to people who are themselves fairly well acquainted with a broad range of theories of consciousness. That said, I suspect that this could be remedied by forming groups of people who bring different talents to the table. In Peaceful Qualia I discussed a potential empirical approach for investigating consciousness which involves having people who specialize in various aspects of the problem (e.g. being great psychonauts, excellent third-person experimentalists, high-quality synthesizers, solid computational modelers, and so on). But until then, I do not anticipate much progress will come from people who are simply very smart and creative – they also need to have either privileged information (such as what you get from combining weird drugs and brain-computer interfaces), or be very knowledgeable about what is going on in the field.
And (4): This is the most difficult and rarest of all, for it requires some degree of the previous three attributes. Their work wouldn’t be possible without the work of many other people in the previous three categories. Yet, of course, they will be the most world-changing of them all. Explicitly, this is the role that we are aiming for at the Qualia Research Institute.
In addition to the above, there are other ways of making highly valuable contributions to the conversation. An example would be those individuals who have become living expressions of current theories of consciousness. That is, people who have deeply understood some paradigm and can propose paradigm-consistent explanations for completely new evidence. E.g. people who can quickly figure out “what would Tononi say about X?” no matter how weird X is. It is my view that one can learn a lot from people in this category. That said… don’t ever expect to change their minds!
A Final Suggestion: Philosophical Speed Dating
To conclude, I would like to make a suggestion in order to increase the value of this and similar conferences: philosophical speed dating. This might be valuable for two reasons. First, I think that a large percentage of people who attend TSC are craving interactions with others who also wonder about consciousness. After all, being intrigued and fascinated by this topic is not very common. Casual interest? Sure. But obsessive curiosity? Pretty uncommon. And most people who attend TCS are in the latter category. At the same time, it is never very pleasant to interact with people who are likely to simply not understand where you are coming from. The diversity of views is so large that finding a person with whom you can have a cogent and fruitful conversation is quite difficult for a lot of people. A Philosophical Speed Dating session in which people quickly state things like their interest in consciousness, take on qualia, preferred approaches, favorite authors, paradigm affinities, etc. would allow philosophical kindred souls to meet at a much higher rate.
And second, in the context of advancing the collective conversation about consciousness, I have found that having people who know where you are coming from (and either share or understand your background assumptions) is the best way to go. The best conversations I’ve had with people usually arise when we have a strong base of shared knowledge and intuitions, but disagree on one or two key points we can identify and meaningfully address. Thus a Philosophical Speed Dating session could lead to valuable collaborations.
And with that, I would like to say: If you do find our approach interesting or worth pursuing, do get in touch.
Till next time, Tucson!
* In Chalmer’s paper about the Meta-Problem of Consciousness he describes his reason for investigating the subject: “Upon hearing about this article, some people have wondered whether I am converting to illusionism, while others have suspected that I am trying to subvert the illusionist program for opposing purposes. Neither reaction is quite correct. I am really interested in the meta-problem as a problem in its own right. But if one wants to place the paper within the framework of old battles, one might think of it as lending opponents a friendly helping hand.” The quality of a philosopher should not be determined only by their ability to make a good case for their views, but also by the capacity to talk convincingly about their opponent’s. And on that metric, David is certainly world-class.
How do psychedelic drugs produce their characteristic range of acute effects in perception, emotion, cognition, and sense of self? How do these effects relate to the clinical efficacy of psychedelic-assisted therapies? Efforts to understand psychedelic phenomena date back more than a century in Western science. In this article I review theories of psychedelic drug effects and highlight key concepts which have endured over the last 125 years of psychedelic science. First, I describe the subjective phenomenology of acute psychedelic effects using the best available data. Next, I review late 19th-century and early 20th-century theories—model psychoses theory, filtration theory, and psychoanalytic theory—and highlight their shared features. I then briefly review recent findings on the neuropharmacology and neurophysiology of psychedelic drugs in humans. Finally, I describe recent theories of psychedelic drug effects which leverage 21st-century cognitive neuroscience frameworks—entropic brain theory, integrated information theory, and predictive processing—and point out key shared features that link back to earlier theories. I identify an abstract principle which cuts across many theories past and present: psychedelic drugs perturb universal brain processes that normally serve to constrain neural systems central to perception, emotion, cognition, and sense of self. I conclude that making an explicit effort to investigate the principles and mechanisms of psychedelic drug effects is a uniquely powerful way to iteratively develop and test unifying theories of brain function.
Subjective rating scale items selected after psilocybin (blue) and placebo (red) (n = 15) (Muthukumaraswamy et al., 2013). “Items were completed using a visual analog scale format, with a bottom anchor of ‘no, not more than usually’ and a top anchor of ‘yes, much more than usually’ for every item, with the exception of ‘I felt entirely normal,’ which had bottom and top anchors of ‘No, I experienced a different state altogether’ and ‘Yes, I felt just as I normally do,’ respectively. Shown are the mean ratings for 15 participants plus the positive SEMs. All items marked with an asterisk were scored significantly higher after psilocybin than placebo infusion at a Bonferroni-corrected significance level of p < 0.0022 (0.5/23 items)” (Muthukumaraswamy et al., 2013, p. 15176).
Neuropharmacology and Neurophysiological Correlates of Psychedelic Drug Effects
Klee recognized that his above hypotheses, inspired by psychoanalytic theory and LSD effects, required neurophysiological evidence. “As far as I am aware, however, adequate neurophysiological evidence is lacking … The long awaited millennium in which biochemical, physiological, and psychological processes can be freely correlated still seems a great distance off” (Klee, 1963, p. 466, 473). What clues have recent investigations uncovered?
A psychedelic drug molecule impacts a neuron by binding to and altering the conformation of receptors on the surface of the neuron (Nichols, 2016). The receptor interaction most implicated in producing classic psychedelic drug effects is agonist or partial agonist activity at serotonin (5-HT) receptor type 2A (5-HT2A) (Nichols, 2016). A molecule’s propensity for 5-HT2A affinity and agonist activity predicts its potential for (and potency of) subjective psychedelic effects (Glennon et al., 1984; McKenna et al., 1990; Halberstadt, 2015; Nichols, 2016; Rickli et al., 2016). When a psychedelic drug’s 5-HT2A agonist activity is intentionally blocked using 5-HT2Aantagonist drugs (e.g., ketanserin), the subjective effects are blocked or attenuated in humans under psilocybin (Vollenweider et al., 1998; Kometer et al., 2013), LSD (Kraehenmann et al., 2017a,b; Preller et al., 2017), and ayahuasca (Valle et al., 2016). Importantly, while the above evidence makes it clear that 5-HT2A activation is a necessary (if not sufficient) mediator of the hallmark subjective effects of classic psychedelic drugs, this does not entail that 5-HT2A activation is the sole neurochemical cause of all subjective effects. For example, 5-HT2A activation might trigger neurochemical modulations ‘downstream’ (e.g., changes in glutamate transmission) which could also play causal roles in producing psychedelic effects (Nichols, 2016). Moreover, most psychedelic drug molecules activate other receptors in addition to 5-HT2A (e.g., 5-HT1A, 5-HT2C, dopamine, sigma, etc.) and these activations may importantly contribute to the overall profile of subjective effects even if 5-HT2A activation is required for their effects to occur (Ray, 2010, 2016).
How does psychedelic drug-induced 5-HT2A receptor agonism change the behavior of the host neuron? Generally, 5-HT2A activation has a depolarizing effect on the neuron, making it more excitable (more likely to fire) (Andrade, 2011; Nichols, 2016). Importantly, this does not necessarily entail that 5-HT2Aactivation will have an overall excitatory effect throughout the brain, particularly if the excitation occurs in inhibitory neurons (Andrade, 2011). This important consideration (captured by the adage ‘one neuron’s excitation is another neuron’s inhibition’) should be kept in mind when tracing causal links in the pharmaco-neurophysiology of psychedelic drug effects.
The concept of functional connectivity rests upon fMRI brain imaging observations that reveal temporal correlations of activity occurring in spatially remote regions of the brain which form highly structured patterns (brain networks) (Buckner et al., 2013). Imaging of brains during perceptual or cognitive task performance reveals patterns of functional connectivity known as functional networks; e.g., control network, dorsal attention network, ventral attention network, visual network, auditory network, and so on. Imaging brains in taskless resting conditions reveals resting-state functional connectivity (RSFC) and structured patterns of RSFC known as resting state networks (RSNs; Deco et al., 2011). One particular RSN, the default mode network (DMN; Buckner et al., 2008), increases activity in the absence of tasks and decreases activity during task performance (Fox and Raichle, 2007). DMN activity is strong during internally directed cognition and a variety of other ‘metacognitive’ functions (Buckner et al., 2008). DMN activation in normal waking states exhibits ‘inverse coupling’ or anticorrelation with the activation of task-positive functional networks, meaning that DMN and functional networks are often mutually exclusive; one deactivates as the other activates and vice versa (Fox and Raichle, 2007).
Taken together, the recently discovered neurophysiological correlates of subjective psychedelic effects present an important puzzle for 21st-century neuroscience. A key clue is that 5-HT2A receptor agonism leads to desynchronization of oscillatory activity, disintegration of intrinsic integrity in the DMN and related brain networks, and an overall brain dynamic characterized by increased between-network global functional connectivity, expanded signal diversity, and a larger repertoire of structured neurophysiological activation patterns. Crucially, these characteristic traits of psychedelic brain activity have been correlated with the phenomenological dynamics and intensity of subjective psychedelic effects.
21st-Century Theories of Psychedelic Drug Effects
Entropic Brain Theory
Entropic Brain Theory (EBT; Carhart-Harris et al., 2014) links the phenomenology and neurophysiology of psychedelic effects by characterizing both in terms of the quantitative notions of entropy and uncertainty. Entropy is a quantitative index of a system’s (physical) disorder or randomness which can simultaneously describe its (informational) uncertainty. EBT “proposes that the quality of any conscious state depends on the system’s entropy measured via key parameters of brain function” (Carhart-Harris et al., 2014, p. 1). Their hypothesis states that hallmark psychedelic effects (e.g., perceptual destabilization, cognitive flexibility, ego dissolution) can be mapped directly onto elevated levels of entropy/uncertainty measured in brain activity, e.g., widened repertoire of functional connectivity patterns, reduced anticorrelation of brain networks, and desynchronization of RSN activity. More specifically, EBT characterizes the difference between psychedelic states and normal waking states in terms of how the underlying brain dynamics are positioned on a scale between the two extremes of order and disorder—a concept known as ‘self-organized criticality’ (Beggs and Plenz, 2003). A system with high order (low entropy) exhibits dynamics that resemble ‘petrification’ and are relatively inflexible but more stable, while a system with low order (high entropy) exhibits dynamics that resemble ‘formlessness’ and are more flexible but less stable. The notion of ‘criticality’ describes the transition zone in which the brain remains poised between order and disorder. Physical systems at criticality exhibit increased transient ‘metastable’ states, increased sensitivity to perturbation, and increased propensity for cascading ‘avalanches’ of metastable activity. Importantly, EBT points out that these characteristics are consistent with psychedelic phenomenology, e.g., hypersensitivity to external stimuli, broadened range of experiences, or rapidly shifting perceptual and mental contents. Furthermore, EBT uses the notion of criticality to characterize the difference between psychedelic states and normal waking states as it “describes cognition in adult modern humans as ‘near critical’ but ‘sub-critical’—meaning that its dynamics are poised in a position between the two extremes of formlessness and petrification where there is an optimal balance between order and flexibility” (Carhart-Harris et al., 2014, p. 12). EBT hypothesizes that psychedelic drugs interfere with ‘entropy-suppression’ brain mechanisms which normally sustain sub-critical brain dynamics, thus bringing the brain “closer to criticality in the psychedelic state” (Carhart-Harris et al., 2014, p. 12).
Integrated Information Theory
Integrated Information Theory (IIT) is a general theoretical framework which describes the relationship between consciousness and its physical substrates (Oizumi et al., 2014; Tononi, 2004, 2008). While EBT is already loosely consistent with the core principles of IIT, Gallimore (2015) demonstrates how EBT’s hypotheses can be operationalized using the technical concepts of the IIT framework. Using EBT and recent neuroimaging data as a foundation, Gallimore develops an IIT-based model of psychedelic effects. Consistent with EBT, this IIT-based model describes the brain’s continual challenge of minimizing entropy while retaining flexibility. Gallimore formally restates this problem using IIT parameters: brains attempt to optimize the give-and-take dynamic between cause-effect information and cognitive flexibility. In IIT, a (neural) system generates cause-effect information when the mechanisms which make up its current state constrain the set of states which could casually precede or follow the current state. In other words, each mechanistic state of the brain: (1) limits the set of past states which could have causally given rise to it, and (2) limits the set of future states which can causally follow from it. Thus, each current state of the mechanisms within a neural system (or subsystem) has an associated cause-effect repertoire which specifies a certain amount of cause-effect information as a function of how stringently it constrains the unconstrained state repertoire of all possible system states. Increasing the entropy within a cause-effect repertoire will in effect constrain the system less stringently as the causal possibilities are expanded in both temporal directions as the system moves closer to its unconstrained repertoire of all possible states. Moreover, increasing the entropy within a cause-effect repertoire equivalently increases the uncertainty associated with its past (and future) causal interactions. Using this IIT-based framework, Gallimore (2015)argues that, compared with normal waking states, psychedelic brain states exhibit higher entropy, higher cognitive flexibility, but lower cause-effect information.
The first modern brain imaging measurements in humans under psilocybin yielded somewhat unexpected results: reductions in oscillatory power (MEG) and cerebral blood flow (fMRI) correlated with the intensity of subjective psychedelic effects (Carhart-Harris et al., 2012; Muthukumaraswamy et al., 2013). In their discussion, the authors suggest that their findings, although surprising through the lens of commonly held beliefs about how brain activity maps to subjective phenomenology, may actually be consistent with a theory of brain function known as the free energy principle (FEP; Friston, 2010).
In one model of global brain function based on the free-energy principle (Friston, 2010), activity in deep-layer projection neurons encodes top-down inferences about the world. Speculatively, if deep-layer pyramidal cells were to become hyperexcitable during the psychedelic state, information processing would be biased in the direction of inference—such that implicit models of the world become spontaneously manifest—intruding into consciousness without prior invitation from sensory data. This could explain many of the subjective effects of psychedelics (Muthukumaraswamy et al., 2013, p. 15181).
The four key features identified in filtration and psychoanalytic accounts from the late 19th and early 20th century continue to operate in 21st-century cognitive neuroscience: (1) psychedelic drugs produce their characteristic diversity of effects because they perturb adaptive mechanisms which normally constrain perception, emotion, cognition, and self-reference, (2) these adaptive mechanisms can develop pathologies rooted in either too much or too little constraint (3) psychedelic effects appear to share elements with psychotic symptoms because both involve weakened constraints (4) psychedelic drugs are therapeutically useful precisely because they offer a way to temporarily inhibit these adaptive constraints. It is on these four points that EBT, IIT, and PP seem consistent with each other and with earlier filtration and psychoanalytic accounts. EBT and IIT describe psychedelic brain dynamics and link them to phenomenological dynamics, while PP describes informational principles and plausible neural information exchanges which might underlie the larger-scale dynamics described by EBT and IIT. Certain descriptions of neural entropy-suppression mechanisms (EBT), cause-effect information constraints (IIT), or prediction-error minimization strategies (PP, FEP) are loosely consistent with Freud’s ego and Huxley’s cerebral reducing valve.
Qualia Computing comment: As you can see above, 21st century theories of psychedelic action have a lot of interesting commonalities. A one-line summary of what they all agree on could be: Psychedelics increase the available state-space of consciousness by removing constraints that are normally imposed by standard brain functioning. That said, they do not make specific predictions about valence. That is, they leave the question of “which alien states of consciousness will feel good and which ones will feel bad” completely unaddressed. In the following posts about the presentations of members of the Qualia Research Institute at The Science of Consciousness 2018 you will see how, unlike other modern accounts, our Qualia Formalist approach to consciousness can elucidate this matter.
I had two or three such experiences on my new batch of LSD, taking perhaps 2 or 3 “hits” (tabs) each time (presumed to be about  micrograms, or “mikes” per tab). And each time the experience became somewhat more familiar, and I learned to think more clearly under its influence. In July 1990 I took a trip to Europe with Tim, a colleague from work, because we were both presenting posters at a neural network conference in Paris, and the company where we worked very kindly funded the travel expenses. Tim and I took this opportunity to plan a little excursion around Europe after the conference, visiting Germany, Austria, Italy, and Switzerland touring in a rented car. When we got to Austria we bought a little tent at a camping store, then we hiked up an enormous mountain in the Alps, and spent the day sightseeing at the top. When I told Tim that I happened to have some LSD with me, his eyes lit up. It turns out he too had been a hippy in his youth, and had even attended the original Woodstock, so he immediately warmed to the idea of taking LSD with me on a mountain top, although he had not done psychedelic drugs in over a decade. So there in the most stupendous and idyllic setting of a mountain in the Austrian alps, early the next morning after camping overnight, we consumed five hits of LSD each, and spent the day in profound wonder at the glory of creation!
I made a few new and interesting discoveries on that mountain top in Austria. First of all, I learned to have a great deal more control of the experience in the following manner. I discovered that the effects of LSD become markedly stronger and more pronounced when you sit still and stare, and clear your mind, much like a state of zen meditation, or pre-hypnotic relaxation. When you do this under LSD, the visual world begins to break up and fragment in a most astonishing way. You tend to lose all sense of self, that is, you lose the distinction between self and non-self. This can be a very alarming experience for those who are prone to panic or anxiety, or for those who insist on maintaining a level of control and awareness of themselves and the world around them. But I also discovered that this mental dissociation and visual confusion can be diminished, and normal consciousness can be largely restored by simply looking around, moving about, and interacting actively with the world around you. Because when you do this, suddenly the world appears as a solid and stable structure again, and your familiar body reappears where it belongs at the center of your world of experience. This discovery greatly enhanced my ability to explore the deeper spaces of consciousness revealed by the drug, while providing an insurance against the natural panic that tends to arise with the dissolusion of the self, and the world around you. It allowed me to descend into the depths of the experience while maintaining a life line back to consensual reality, like a spelunker descending into the bowels of the deep underground cavern of my mind, while always able to return safely to the surface. And what a splendid and magnificent cavern it was that I discovered within my mind!
One of the most prominent aspects of consciousness that has puzzled philosophers and psychologists for centuries is the unity of conscious experience. We feel that we live in a world that surrounds our body, and that world appears as a single “picture” or volumetric spatial structure, like a theatre set, every piece of which takes its proper place in the panorama of surrounding experience. It has always been somewhat difficult to grasp this notion of conscious unity, because it is difficult to even conceptualize the alternative. What would consciousness be like if it were not unified? What does that even mean? Under LSD you can discover what non-unified consciousness is like for yourself, and that in turn by contrast offers profound insights as to the nature and meaning of unified consciousness. Again, the most interesting revelations of the psychedelic experience are not confined to that experience itself, but they reveal insights into the nature of normal conscious experience that might otherwise be missed due to its familiarity. In fact, I realized much later, even normal consciousness has aspects which are not unified.
The most familiar example of non-unified consciousness is seen in binocular vision. Under normal conditions the two eyes view the same scene and produce a three-dimensional “picture” in the mind that is a unified construction based on the information from both eyes simultaneously. But everyone knows the experience of double vision. For those with greater control over their own visual function, double vision is easily achieved by simply staring into space and relaxing the eyes. As a vision scientist myself, I have trained myself to do this so as to be able to “free fuse” a binocular pair of left-eye, right-eye images to create the perception of a 3D scene. For those who have difficulty with this, a similar experience can be had by holding a small mirror at an angle close in front of one eye, so as to send very different images into the two eyes. Whichever way you do it, the result is rather unremarkable in its familiarity, and yet when you think of it, this is in fact an example of disunity of conscious experience that is familiar to one and all. For what you see in double vision is actually two visual experiences which are seen as if they are superimposed in some manner, and yet at the same time they are also experienced each in its own separate disconnected space. It is generally possible to observe the correspondence between these two disconnected visual experiences, for example to determine which point in one eye view relates to a particular point in the other, as if viewing two slide transparencies that are overlaid on top of one another, although this correspondence is shifting and unstable, as the vergence between your two eyes tends to wander when binocular fusion is broken. But in fact it is more natural to simply ignore that correspondence and to view the two visual experiences as separate and disconnected spaces that bear no significant spatial relation to each other. When the images in our two eyes do not correspond, we tend to focus on one while ignoring the other, like an experienced marksman who no longer has to close his idle eye while aiming a gun. And yet, although the image from the idle eye is generally ignored, it has not left consciousness entirely, and with an effort, or perhaps more accurately, with an absence of effort or focus, it is possible to experience both views simultaneously.
In the trance-like state of yoga-like meditation performed under LSD, the entire visual world breaks up and fragments in this manner into a multitude of disconnected parallel conscious experiences, each one only loosly related spatially to the other experiences in the visual field. The effect is much enhanced by the fact that your eyes actually diverge or relax in this mental state, as they do under binocular fission, and this helps trigger the state of visual confusion as your mind gives up on trying to make sense of what it is seeing. As in Zen meditation, the LSD trance state is a passive or receptive state of consciousness that allots equal attention, or perhaps lack of attention, to all components of experience, which is why they appear in parallel as separate disconnected pieces. The state of normal active consciousness resists this kind of parallel confusion, and tends to select and focus on the the most significant portion, like the marksman aiming a gun, suppressing alternative experiences such as the view from the idle eye.
The deep LSD-induced trance state can be easily broken by simply moving the eyes, so conversely, the deeper states are achieved by complete mental and physical relaxation, with glazed eyes staring blankly into space. But of all the separate fragments of visual experience observed in this mental state, there is one special fragment located at the very center of the visual field, the foveal center, that appears somewhat sharper and clearer than the rest of the visual field. In fact, the visual fragmentation is somewhat like a kind of tunnel vision in which the peripheral portions of the visual field break off and disconnect from this central portion of the experience. But while the peripheral fragments become separated from the whole, they are never entirely and completely independent, but appear to interact with each other, and especially with the central foveal image in characteristic ways. For example if the foveal image shows a couple of blades of grass, twitching and dancing in the wind, then if any of the peripheral fragments of visual experience happen to show a similar image, i.e. blades of grass at a similar angle and twitching and dancing in synchrony with those in the foveal view, then the central and peripheral images become instantly coupled into a larger unified perceptual experience of a global motion sweeping through the image. Instead of a million blades of grass each twitching individually, we perceive the invisible wind as a wave of synchronous motion that sweeps invisibly across the blades of grass. The waves of motion caused by the wind are perceived as waves of energy across the visual field, a perceptual experience of something larger than the individual grass blades that collectively give rise to it. By careful adjustment of my state of relaxation, I found I could relax until the visual world fragmented into a million independent experiences, and I could gently bring it back into focus, as first a few, and then ever more of the fragmented visual experiences coupled together into fewer separate, and eventually a single unified global experience, much like the moment of binocular fusion when the two monocular images finally lock into each other to produce a single binocular experience.
When the visual world was locked into a unified perceptual experience, even then there were instabilities in local portions of the scene. A little detail seen in distant trees appears first as a mounted horseman, then pops abruptly into a hand with three fingers extended, then to a duck on a branch, then back to the mounted horseman, all the while the actual shape and color perceived remain unchanged, it is only the interpretation, or visual understanding of that pattern that switches constantly, as when a child sees mountains and castles in the clouds. One of the many possible interpretations is of a dead tree with leafless branches, (the veridical percept of what was actually there) and that is the only alternative that enters consciouseness under normal circumstances. The effect of LSD is to make the visual system more tolerant of obvious contradictions in the scene, such as a giant horseman frozen in a line of trees. The effect is like those surrealistic Dali paintings, for example the Three Ages of Man, shown in Figure 2.1, where one sees a single coherent scene, local parts of which spontaneously invert into some alternative interpretation. This is very significant for the nature of biological vision, for it shows that vision involves a dynamic relaxation process whose stable states represent the final perceptual interpretation.
There was another interesting observation that I made that day. I noticed that under LSD things appear a little more regular and geometrical than they otherwise do. It is not the shape of things that is different under LSD, but rather the shape of the things we see in objects. For example a cloud is about as irregular and fragmented a shape as a shape can be, and yet we tend to see clouds in a simplified cartoon manner, as a little puff composed of simple convex curves. A real cloud under closer inspection reveals a ragged ugly appearance with very indefinite boundaries and irregular structure. Under LSD the cloud becomes even more regular than usual. I began to see parts of the cloud as regular geometrical shapes, seeing the shapes in the shapes of the cloud as if on a transparent overlay.
Another rather astonishing observation of the LSD experience was that the visual world wavered and wobbled slowly as if the visual scene was painted on an elastic canvas that would stretch over here while shrinking over there, with great waves of expansion and contraction moving slowly across the scene, as if the whole scene was “breathing”, with its component parts in constant motion relative to each other. This was perhaps the most compelling evidence that the world of experience is not the solid stable world that it portrays. Figure 2.2 shows a sketch I made shortly after my alpine mountain adventure to try to express the wavery elasticity and the visual regularity I had observed under LSD. This picture is of course an exaggeration, more of an impression than a depiction of how the experience actually appeared.
The geometrical regularity was particularly prominent in peripheral vision, when attending to the periphery without looking to see what is there. Usually peripheral vision is hardly noticed, giving the impression of a homogeneous visual field, but under LSD the loss of resolution in peripheral vision becomes more readily apparent, especially when holding a fixed and glassy stare. And in that periphery, objects like trees or shrubs appear more regular and geometrical than they do in central vision, like artificial Christmas trees with perfectly regular spacing of brances and twigs. Again, it was not the raw image in the periphery that appeared regular or geometrical, but rather it was the invisible skeleton of visual understanding derived from that raw colored experience that exhibits the more regular features. And suddenly I could see it. This is the way the visual system encodes visual form in a compact or compressed manner, by expressing shape in terms of the next nearest regular geometrical form, or combination of forms. Children draw a tree as a circular blob of leaves on top of a straight vertical trunk, or a pine tree as a green triangle with saw-tooth sides. It is not that we see trees in those simplified forms, but rather that we see those simplified forms in the trees, and the forms that we perceive in these invisible skeletons are the expression of our understanding of the shapes we perceive those more irregular forms to have. This was later to turn into my harmonic resonance theory of the brain, as I sought an explanation for this emerging regularity in perception, but in 1990 all I saw was the periodicity and the symmetry, and I thought they were profoundly beautiful.
My friend Tim who had not done LSD for many years, responded to this sudden 5 hit dose by going into a state of complete dissociation. He lay down on the forest floor with glassy eyes, muttering “It is TOO beautiful! It is TOO beautiful!” and he did not respond to me, even when I stared him straight in the face. He reported afterwards that he found himself in a giant Gothic cathedral with the most extravagantly elaborate and brightly painted ornamental decorations all around him. This too can be seen as an extreme form of the regularization discussed above. Under the influence of this powerful dose, Tim’s visual brain could no longer keep up with the massive irregularity of the forest around him, and therefore presented the forest in simplified or abbreviated form, as the interior of a Gothic cathedral. It captures the large geometry of a ground plane that supports an array of vertical columns, each of which fans out high overhead to link up into an over-arching canopy of branches. The only difference is that in the Gothic cathedral the trees are in a regular geometrical array, and each one is a masterpiece of compound symmetry, composed of smaller pillars of different diameters in perfectly symmetrical arrangements, and studded with periodic patterns of ribs, ridges, or knobby protruberances as a kind of celebration of symmetry and periodicity for their own sake. There is a kind of geometrical logic expressed in the ornamental design. If part of the cathedral were lost or destroyed, the pattern could be easily restored by following the same logic as the rest of the design. In information-theoretic terms, the Gothic cathedral has lots of redundancy, its pattern could be expressed in a very much simpler compressed geometrical code. In Tim’s drug-addled brain his visual system could only muster a simple code to represent the world around him, and that is why Tim saw the forest as a Gothic cathedral. Under normal conditions, the additional information of irregularity, or how each tree and branch breaks from the strict regularity of the cathedral model of it, creates the irregular world of experience that we normally see around us. This suggests that the beautiful shapes of ornamental art are not the product of the highest human faculty, as is commonly supposed, but rather, ornamental art offers a window onto the workings of a simpler visual system, whose image of the world is distorted by artifacts of the representational scheme used in the brain. The Gothic cathedral gives a hint as to how the world might appear to a simpler creature, a lizard, or a snake, to whom the world appears more regular than it does to us, because its full irregularity is too expensive to encode exhaustively in all its chaotic details. Of course the flip-side of this rumination is that the world that we humans experience, even in the stone-cold sober state, is itself immeasurably simpler, more regular and geometric, that the real world itself, of which our experience is an imperfect replica. In the words of William Blake, “If the doors of perception were cleansed, everything would appear to man as it is, infinite.”
While I was a PhD student at Boston University, my parents owned a beautiful ski lodge house in the picturesque town of Mittersill in the mountains of New Hampshire, and on spring breaks or long week-ends I would invite my friends, the other PhD candidates, up to Mittersill where we would take long hikes up the mountain, and spend evenings by the fireplace. I introduced a small circle of my friends to the illuminating experience of LSD, in the hopes of sharing some of my perceptual discoveries with them, and perhaps inducing them to learn to use the experience to make discoveries of their own. Eventually Mittersill became associated in our minds with these group trips with an ever-shrinking circle of true diehard psychonauts, making our regular pilgrimage up the mountain in search of Truth and to touch the face of God. We always brought a goodly supply of Happy T’Baccy, which provides a beautiful complement and bemellowment to the otherwise sometimes sharp and jangly LSD experience. Our pattern was usually to arrive on a Friday night, cook up a great feast, and spend an evening by the fire, drinking beer and/or wine and passing the pipe around until everyone felt properly toasted. The talk was often about the workings of mind and brain, since we were all students of cognitive and neural systems. We were all adept computer programmers and well versed in mathematics as part of our PhD studies, so we all understood the issues of mental computation and representation, and I found the conversations about the computational principles of the mind, to be most interesting and intellectually stimulating. This was the high point of my academic career, this is why people want to be scientists. The next morning we would rise early, and after a hearty breakfast, we would all set off up the mountain, which was a steep brisk climb of two or three hours. About half way up the mountain, at a carefully pre-planned time, we would stop, and each “dose up” with our individually chosen dose of LSD for the occasion, timed to reach the peak of the experience about the time we reached the peak of the mountain. Then we would continue our climb through the rich lush mountain forests of New Hampshire to the top of Maida Vale, the sub-peak next to Canon Mountain, from whence a stupendous view opened up across to Canon Mountain and the vast valley below. We would settle ourselves comfortably at some location off the beaten track, and spend the best hours of the day just dreaming crazy thoughts and drinking in the experience
By now I had perfected my introspective techniques to the point that I could voluntarily relax my mind into a state of total disembodiment. The visual world began to fragment, first into two large pieces as binocular fusion was broken, then into a few smaller fragments, and eventually into a miriad of separate fragments of consciousness, like the miriad reflections from a shattered mirror. I was fascinated by this state of consciousness, and how different it was from normal consensual reality. Most alarming or significant was the total absence of my body from its normal place at the center of my world. As the world began to fragment, my body would fragment along with it, disconnected pieces of my body seeming to exist independently, one part here, another over there, but in separate spaces that did not exist in a distinct spatial relation to each other, but as if in different universes, like reflections from different shards of a shattered mirror. And as the visual world attained total fragmentation, all evidence of my body completely vanished, and I lived the experience of a disembodied spirit, pure raw experience, just sensations of color, form, and light. I felt safe and secure in this environment among friends, so I did not mind the total vulnerability afforded by a complete functional shutdown of my mind in this manner. Besides, I had learned that I could snap back together again to a relatively normal consciousness at will, simply by getting up and looking around, and interacting with the world. I was endlessly fascinated by the state of complete disembodiment, and one feature of it impressed itself on me again and again, the geometric regularity of it all. There was a powerful tendency for everything to reduce to ornamental patterns, geometrical arrangements of three-dimensional shapes, like so many glistening gems in a jewelry store, with rich periodic and symmetrical patterns in deep vibrant colors. The deeper I plunged into the experience, the simpler and more powerfully emotive those patterns became. And since my body had totally vanished, these patterns were no longer patterns I viewed out in the world, but rather, the patterns were me, I had become the spatial patterns which made up my experience. I began to see that symmetry and periodicity were somehow primal to experience.
I remember lying on my back and watching the clouds in the sky overhead. Weather patterns are often chaotic at the tops of mountains, and on more than one occasion we were located at a spot where the clouds that formed on the windward side of the mountain were just cresting the summit, where they would dissove in a continuous process of chaotic fragmentation, a veritable Niagra Falls of nebular dissolution, evocative of the fragmentation of my psychedelic experience. The shattered shreds of cloud, viewed from this close up, were about the most ragged and irregular shapes you could imagine, and yet under the influence of the drug I kept seeing fleeting geometrical patterns in them. There were great circular pinwheels and arabesques, patterns like those carved in the doors of Gothic cathedrals, but each flashing in and out of brief existence so quickly that it would be impossible to draw them. I began to realize that the human mind is one great symmetry engine, that the mind makes sense of the world it sees by way of the symmetries that it finds in it. Symmetry is the glue that binds the fragments of experience into coherent wholes.
Figure 2.3 shows a series of paintings by artist Louis Wain, that I find very evocative of the LSD experience. Wain suffered a progressive psychosis that manifested itself in his art, which was originally quite realistic, becomming progressively more abstract and ornamental, in the manner I observed in the various stages or levels of my LSD dissociation. Figure 2.3 A shows a fairly realistic depiction of a cat, but there are curious artifacts in the textured background, a mere hint of periodicity breaking out. I would see such artifacts everywhere, almost invisible, fleeting, and faint, reminiscent of the ornamental pinstripe patterns painted on trucks and motorcycles, a kind of eddy in the stream of visual consciousness as it flows around visual features in the scene. As I descended into the fully dissociated states, the patterns would become more like Figure 2.3 B, C, and D, breathtakingly ornate, with many levels of compound symmetry, revealing the eigenfunctions of perceptual representation, the code by which visual form is represented in the brain.
At times we would break free from our individual reveries, and share absurd nonsensical conversations about our observations. One time, looking down at the vast valley stretching out below us, a vista that seemed to stretch out to distances beyond comprehension, my old friend Peter said that it was hard to tell whether all that scenery was just “way out there”, or was it “way WAY out there?” Of course we both laughed heartily at the absurdity of his statement, but I knew exactly what he meant. When viewing such a grand vista under normal consciousness, one is deeply impressed by the vastness of the view.
But under the influence of the drug, the vista somehow did not look quite as large as we “knew” that it really was. What Peter was saying was that for some strange reason, the world had shrunken back in on us, and that magnificently vast valley had shrunken to something like a scale model, or a diorama, where it is easy to see how vast the modeled valley is supposed to be, but the model itself appears very much smaller than the valley it attempts to portray. What Peter was observing was the same thing I had observed, and that was beginning to even become familiar, that the world of our experience is not a great open vastness of infinite space, but like the domed vault of the night sky, our experience is bounded by, and contained within, a vast but finite spherical shell, and under the influence of psychedelic drugs that shell seemed to shrink to smaller dimensions, our consciousness was closing in on its egocentric center. Many years later after giving it considerable thought, I built the diorama shown in Figure 2.4 to depict the geometry of visual experience as I observed it under LSD.
And when I was in the completely disembodied state, my consciousness closed in even smaller and tighter, the range of my experience was all contained within a rather modest sized space, like a glass showcase in a jewelry store, and the complexity of the patterns in that space was also reduced, from the unfathomably complex and chaotic fractal forms in a typical natural scene, to a much simpler but powerfully beautiful glistening ornamental world of the degree of complexity seen in a Gothic cathedral. The profound significance of these observations dawned on me incrementally every time we had these experiences. I can recall fragmentary pieces of insights gleaned through the confusion of our passage down the mountain, stopping to sit and think wherever and whenever the spirit took us. At one point three of us stopped by a babbling brook that was crashing and burbling through the rocks down the steep mountain slope. We sat in silent contemplation at this primal “white noise” sound, when Lonce commented that if you listen, you can hear a million different sounds hidden in that noise. And sure enough when I listened, I heard laughing voices and honking car horns and shrieking crashes and jangly music and every other possible sound, all at the same time superimposed on each other in a chaotic jumbled mass. It was the auditory equivalent of what we were seeing visually, the mind was latching onto the raw sensory experience not so much to view it as it really is, but to conjure up random patterns from deep within our sensory memory and to match those images to the current sensory input. And now I could see the more general concept. We experience the world by way of these images conjured up in our minds. I came to realize why the LSD experience was enjoyed best in outdoors natural settings, and that is because the chaos of a natural scene, with its innumerable twigs and leaves and stalks, acts as a kind of “white noise” stimulus, like the babbling brook, a stimulus that contains within it every possible pattern, and that frees our mind to interpret that noise as anything it pleases.
On one occasion, on arrival back down at the lodge, our minds were still reeling, and we were not yet ready to leave the magnificence of the natural landscape for the relatively tame and controlled environment indoors, so Andy and I stopped in the woods behind the house and just stood there, like deer in the headlights, drinking in the experience. It was a particularly dark green and leafy environment in the shadow behind the house, with shrubs and leaves at every level, around our ankles, our knees, our shoulders, and all the way up to a leafy canopy high overhead, and at every depth and distance from inches away to the farthest visible depths of the deep green woods. The visual chaos was total and complete, the world already fragmented into millions and millions of apparently disconnected features and facets uniformly in all directions, that it hardly required LSD to appreciate the richness of this chaotic experience. But under LSD, and with the two of us standing stock still for many long minutes of total silence, we both descended into a mental fragmentation as crazy as the fragmented world around us. My body disappeared from my experience, and I felt like I became the forest; the forest and all its visual chaos was me, which in a very real sense it actually was. And in that eternal timeless moment, wrapped in intense but wordless thought, I recognized something very very ancient and primal in my experience. I felt like I was sharing the experience of some primal creature in an ancient swamp many millions of years ago, when nature was first forging its earliest models of mind from the tissue of brain. I saw the world with the same intense attentive concentration, bewilderment, and total absence of human cogntive understanding, as that antediluvian cretaceous lizard must have experienced long ago and far away. The beautiful geometrical and symmetrical forms that condensed spontaneously in my visual experience were like the first glimmerings of understanding emerging in a primitive visual brain. This is why I do psychedelic drugs, to connect more intimately with my animal origins, to celebrate the magnificent mental mechanisms that we inherit from the earliest animal pioneers of mind.
One time after we had descended from the mountain and were sitting around the lodge drinking and smoking in a happy state of befuddlement, a peculiar phenomenon manifested itself that made a deep impression on me. It was getting close to supper time and somebody expressed something to that effect. But our minds were so befuddled by the intoxication that we could only speak in broken sentences, as we inevitably forgot what we wanted to say just as we started saying it, instantly confused by our own initial words. So the first person must have said something like “I’m getting hungry. Do you think…” and then tailed off in confusion. But somebody else would immediately sense the direction that thought was going, and would instinctively attempt to complete the sentence with something like “…we otta go get…” before himself becoming confused, at which a third person might interject “…something to eat?” It does not sound so remarkable here in the retelling, but what erupted before our eyes was an extraordinarily fluid and coherent session of what we later referred to as group thought, where the conversation bounced easily from one person to the next, each person contributing only a fragmentary thought, but nobody having any clear idea of what the whole thought was supposed to be, or how it was going to end. What was amazing about the experience was the coherence and purposefulness of the emergent thought, how it seemed to have a mind of its own independent of our individual minds, even though of course it was nothing other than the collective action of our befuddled minds. It was fascinating to see this thought, like a disembodied spirit, pick up and move our bodies and hands in concerted action, one person getting wood for the fire, another getting out a frying pan, a third going for potatoes, or to open a bottle of wine, none of it planned by any one person, and yet each person chipped in just as and when they thought would be appropriate, as the supper apparently “made itself” using us as its willing accomplices. It was reminiscent of the operational principle behind a ouija board, where people sitting in a circle around a table, all rest an index finger on some movable pointer on a circular alphabet board, and the pointer begins to spell out some message under the collective action of all those fingers. At first the emergent message appears random, but after the first few letters have been spelled out, the participants start to guess at each next letter, and without anyone being overtly aware of it, the word appears to “spell itself” as if under the influence of a supernatural force. As with the ouija board, none of us participating in the group thought experience could hold a coherent thought in their head, and yet coherent thoughts emerged nevertheless, to the bewilderment of us all. And later I observed the same phenomenon with different LSD parties. I have subsequently encountered people well versed in the psychedelic experience who claim with great certainty to have experienced mental telepathy in the form of wordless communication and sharing of thoughts. But for us hard-nosed scientific types, the natural explanation for this apparently supernatural experience is just as wonderous and noteworthy, because it offers a hint as to how the individual parts of a mind act together in concert to produce a unified coherent pattern of behavior that is greater than the mere sum of its constituent parts. The principle of group thought occurs across our individual brains in normal sober consciousness as we instinctively read each other’s faces and follow each other’s thoughts, and it is seen also whenever people are moving a heavy piece of furniture, all lifting and moving in unison in a coherent motion towards some goal. But the psychedelic experience highlighted this aspect of wordless communication and brought it to my attention in clearer, sharper focus.
As the evening tailed on and the drug’s effect gradually subsided in a long slow steady decline, we would sit by the fire and pass a pipe or joint around, and share our observations and experiences of the day. At one point Lonce, who had just taken a puff of a joint, breathed out and held it contemplatively for a while, before taking a second puff and passing it on to the next person in the circle. I objected to this behavior, and accused Lonce of “Bogarting” the joint – smoking it all by himself without passing it along. Lonce responded to this with an explanation that where he comes from, people don’t puff and pass in haste, but every man has the right to a few moments of quiet contemplation and a second puff before passing it along. That was, he explained, the civilized way of sharing a joint. So we immediately adopted Lonce’s suggestion, and this method of sharing a joint has henceforth and forever since been referred to by us as the “Lonce Method”.
As I have explained, the purpose of all this psychonautical exploration was not merely for our own entertainment, although entertaining it was, and to the highest degree. No, the primary purpose of these psychonautical exploits was clear all along at least in my mind, and that was to investigate the theoretical implications of these experiences to theories of mind and brain. And my investigations were actually beginning to bear fruit in two completely separate directions, each of which had profound theoretical implications. At that time I was studying neural network theories of the brain, or how the brain makes sense of the visual world. A principal focus of our investigation was the phenomena of visual illusions, like the Kanizsa figure shown in Figure 2.5 A. It is clear that what is happening here is that the visual mind is creating illusory contours that link up the fragmentary contours suggestive of the illusory triangle. In our studies we learned of Stephen Grossberg’s neural network model of this phenomenon. Grossberg proposed that the visual brain is equipped with oriented edge detector neurons that fire whenever a visual edge passes through their local receptive field. These neurons would be triggered by the stark black / white contrast edges of the stimulus in Figure 2.5 A. A higher level set of neurons would then detect the global pattern of collinearity, and sketch in the illusory contour by a process of collinear completion. These higher level “cooperative cells” were equipped with much larger elongated receptive fields, long enough to span the gap in the Kanizsa figure, and the activation of these higher level neurons in turn stimulated lower level local edge detector neurons located along the illusory contour, and that activation promoted the experience of an illusory contour where there is none in the stimulus
I believed I was seeing these illusory contours in my LSD experience, as suggested by all the curvy lines in my sketch in Figure 2.2 above. But I was not only seeing the contours in illusory figures, I was seeing “illusory” contours just about everywhere across the visual field. But curiously, these contours were not “visible” in the usual sense, but rather, they are experienced in an “invisible” manner as something you know is there, but you cannot actually see. However I also noticed that these contours did have an influence on the visible portions of the scene. I have mentioned how under LSD the visual world tends to “breathe”, to waver and wobble like a slow-motion movie of the bottom of a swimming pool viewed through its surface waves. In fact, the effect of the “invisible” contours was very much like the effect of the invisible waves on the surface of the pool, which can also be seen only by their effects on the scene viewed through them. You cannot see the waves themselves, all you can see is the wavering of the world caused by those waves. Well I was observing a very similar phenomenon in my LSD experience. I devised a three-dimensional Kanizsa figure, shown in Figure 2.5 B, and observed that even in the stone-cold sober state, I could see a kind of warp or wobble of the visual background behind the illusory contour caused by the figure, especially if the figure is waved back and forth gently against a noisy or chaotic background. So far, my LSD experiences were consistent with our theoretical understanding of the visual process, confirming to myself by direct observation an aspect of the neural network model we were currently studying in school.
But there was one aspect of the LSD experience that had me truly baffled, and that was the fantastic symmetries and periodicities that were so characteristic of the experience. What kind of neural network model could possibly account for that? It was an issue that I grappled with for many months that stretched into years. In relation to Grossberg’s neural network, it seemed that the issue concerned the question of what happens at corners and vertices where contours meet or cross. A model based on collinearity alone would be stumped at image vertices. And yet a straightforward extension of Grossberg’s neural network theory to address image vertices leads to a combinatorial explosion.The obvious extension, initially proposed by Grossberg himself, was to posit specialized “cooperative cells” with receptive fields configured to detect and enhance other configurations of edges besides ones that are collinear. But the problem is that you would need so many different specialized cells to recognize and complete every possible type of vertex, such as T and V and X and Y vertices, where two or more edges meet at a point, and each of these vertex types would have to be replicated at every orientation, and at every location across the whole visual field! It just seemed like a brute-force solution that was totally implausible.
Then one day after agonizing for months on this issue, my LSD observations of periodic and symmetrical patterns suddenly triggered a novel inspiration. Maybe the nervous system does not require specialized hard-wired receptive fields to accomodate every type of vertex, replicated at every orientation at every spatial location. Maybe the nervous system uses something much more dynamic and adaptive and flexible. Maybe it uses circular standing waves to represent different vertex types, where the standing wave can bend and warp to match the visual input, and standing waves would explain all that symmetry and periodicity so clearly evident in the LSD experience as little rotational standing waves that emerge spontaneously at image vertices, and adapt to the configuration of those vertices. Thanks to illegal psychotropic substances, I had stumbled on a staggeringly significant new theory of the brain, a theory which, if proven right, would turn the world of neuroscience on its head! My heart raced and pounded at the implications of what I had discovered. And this theory became the prime focus of my PhD thesis (Lehar 1994), in which I did computer simulations of my harmonic resonance model that replicated certain visual illusions in a way that no other model could. I had accomplished the impossible. I had found an actual practical use and purpose for what was becoming my favorite pass-time, psychedelic drugs! It was a moment of glory for an intrepid psychonaut, a turning point in my life. Figure 2.6 shows a page from my notebook dated October 6 1992, the first mention of my new theory of harmonic resonance in the brain.
Compare the above descriptions of point-of-view fragmentation, visual coherence, and symmetry as experienced on LSD, with our very own account of symmetrical pattern completion during psychedelic experiences as presented in Algorithmic Reduction of Psychedelic States (slightly edited for clarity):
Lower Symmetry Detection and Propagation Thresholds
Finally, this is perhaps the most interesting and ethically salient effect of psychedelics. The first three effects (tracers, drifting, and pattern recognition) are not particularly difficult to square with standard neuroscience. This fourth effect, while not incompatible with connectionist accounts, does suggest a series of research questions that may hint at an entirely new paradigm for understanding consciousness.
We have not seen anyone in the literature specifically identify this effect in all of its generality. The lowering of the symmetry detection threshold really has to be experienced to be believed. We claim that this effect manifests in all psychedelic experiences to a greater or lesser extent, and that many effects can in fact be explained by simply applying this effect iteratively.
Psychedelics make it easier to find similarities between any two given phenomenal objects. When applied to perception, this effect can be described as a lowering of the symmetry detection threshold. This effect is extremely general and symmetry should not be taken to refer exclusively to geometric symmetry.
How symmetries manifest depends on the set and setting. Researchers interested in verifying and exploring the quantitative and subjective properties of this effect will probably have to focus first on a narrow domain; the effect happens in all experiential modalities.

Symmetry detection during psychedelic experiences requires that one’s attention interprets a given element in the scene as a symmetry element. Symmetry elements are geometrical points of reference about which symmetry operations can take place (such as axes of rotation, mirror planes, hyperplanes, etc.). In turn, a collection of symmetry elements defines a symmetry structure in the following way: A symmetry structure is a set of n-dimensional symmetry elements for which the qualities of the experience surrounding each element obeys the symmetry constraints imposed by all the elements considered together.
Psychedelic symmetry detection can be (and typically is) recursively applied to previously constructed symmetry structures. At a given time multiple independent symmetry structures can coexist inside an experience. By guiding one’s attention one can make these structures interact and ultimately merge. Formally, each symmetry structure is capable of establishing a merging relationship with another symmetry structure. This is achieved by simultaneously focusing one’s attention on both. These relationships are fleeting, but they influence the evolution of the relative position of each symmetry element. When two symmetry structures are in a merging relationship, it is possible to rearrange them (with the aid of drifting and pattern recognition) to create a symmetrical structure that incorporates the symmetry elements of both substructures at once. To do so, one’s mind can either detect one (or several) more symmetry elements along which the previously-existing symmetry elements are made to conform, or, alternatively, if the two pre-existing symmetry structures share a symmetry element (e.g. an axis of rotation of order 3), these corresponding identical symmetry elements can fuse and become a bridge that merges both structures.
Surprisingly, valence seems to be related to psychedelic symmetry detection. As one constructs symmetry structures, one becomes aware of an odd and irresistible subjective pull towards building even higher levels of symmetry. In other words, every time the structure of one’s experience is simplified by identifying a new symmetry element in the scene, one’s whole experience seems to snap into a new (simplified) mode, and this comes with a positive feeling. This feeling can take many forms: it may feel blissful, interesting, beautiful, mind-expanding, and/or awe-producing, all depending on the specific structures that one is merging. Conversely when two symmetry structures are such that merging them is either tricky of impossible, this leads to low valence: frustration, anxiety, pain and an odd feeling of being stuck between two mutually unintelligible worlds. We hypothesize that this is the result of dissonance between the incompatible symmetry structures.
If one meditates in a sensorially-minimized room during a psychedelic experience while being aware that one’s symmetry detection threshold has been lowered by the substance, one can recursively re-apply this effect to produce all kinds of complex mathematical structures that incorporate complex symmetry element interactions. In other words, with the aid of concentration one can climb the symmetry gradient (i.e. increase the total number of symmetry elements) up to the point where the degrees of freedom afforded by the symmetry structure limit any further element from being incorporated into it. We will call these experiences peak symmetry states.
Future research should explore and compare the various states of consciousness that exhibit peak symmetry. There is very likely an enormous number of peak symmetry states, some of which are fairly suboptimal and others that cannot be improved upon. If there is a very deep connection between valence, symmetry, information and harmony, it would very likely show in this area. Indeed, we hypothesize that the highest levels of valence that can be consciously experienced involve peak symmetry states. Anecdotally, this connection has already been verified, with numerous trip reports of people achieving states of unimaginable bliss by inhabiting peak symmetry states (often described as fractal mandala-like mirror rooms).
The range of peak symmetry states include fractals, tessellations, graphs, and higher dimensional projections. Which one of these states contains the highest degree of inter-connectivity? And if psychedelic symmetry is indeed related to conscious bliss, which experience of symmetry is human peak bliss?
Higher Order Symmetry
Mirror Symmetry Tessellation
The pictures above all illustrate possible peak symmetry states one can achieve by combining psychedelics and meditation. The pictures illustrate only the core structure of symmetries that are present in these states of consciousness. What is being reflected is the very raw “feels” of each patch of your experiential field. Thus these pictures really miss the actual raw feelings of the whole experience. They do show, however, a rough outline of symmetrical relationships possible in one of these experiences.
Since control interruption is also co-occurrent with the psychedelic symmetry effect, previously-detected symmetries tend to linger for long periods of time. For this reason, the kinds of symmetries one can detect at a given point in time is a function of the symmetries that are currently being highlighted. And thanks to drifting and pattern recognition enhancement, there is some wiggle room for your mind to re-arrange the location of the symmetries experienced. The four effects together enable, at times, a smooth iterative integration of so many symmetries that one’s consciousness becomes symmetrically interconnected to an unbelievable degree.
What may innocently start as a simple two-sided mirror symmetry can end up producing complex arrangements of self-reflecting mirrors showing glimpses of higher and higher dimensional symmetries. Studying the mathematical properties of the allowed symmetries is a research project that has only just begun. I hope one day dedicated mathematicians describe in full the class of possible high-order symmetries that humans can experience in these states of consciousness.
Anecdotally, each of the 17 possible wallpaper symmetry groups can be instantiated with this effect. In other words, psychedelic states lower the symmetry detection threshold for all of the mathematically available symmetrical tessellations.
All of the 17 2-dimensional wallpaper groups can be experienced with symmetry planes detected, amplified and re-arranged during a psychedelic experience.
Revising the symmetrical texture repetition of grass shown above, we can now discover that the picture displays the wallpaper symmetry found in the lower left circle above:
In very high doses, the symmetry completion is so strong that at any point one risks confusing left and right, and thus losing grasp of one’s orientation in space and time. Depersonalization is, at times, the result of the information that is lost when there is intense symmetry completion going on. One’s self-models become symmetrical too quickly, and one finds it hard to articulate a grounded point of view.
LSD-like states allow the global binding of otherwise incompatible schemas by softening the degree to which neighborhood constraints are enforced. The entire experience becomes a sort of chaotic superposition of locally bound islands that can, each in its own way, tell sensory-linguistic stories in parallel about the unique origin and contribution of their corresponding gestalts to the narrative of the self.
This phenomenon forces, as it were, the onset of cognitive dissonance between incompatible schemas that would otherwise evade mutual contact. On the bright side, it also allows mutual resonance between parts that agree with each other. The global inconsistencies are explored and minimized. One’s mind can become a glorious consensus.
Each square represents, and carries with it, the information of a previously experienced cognitive gestalt (situational memories, ideas, convictions, etc.). Some gestalts never come up together naturally. The LSD-like state allows their side-by-side comparison.
In therapy, LSD-like states had been used for many decades in order to integrate disparate parts of one’s personality into a (more) coherent and integrated lifeworld. But scientists at the beginning didn’t know why this worked.
The Turing module then discovered that the kaleidoscopic world of acid can be compared to raising the temperature within an Ising model. If different gestalts imply a variety of semantic-affective constraints, kaleidoscopic Frame Stacking has the formal effect of expanding the region of one’s mind that is taken into consideration for global consistency at any given point in time. The local constraints become more loose, giving global constraints the upper hand. The degree of psychedelia is approximately proportional to the temperature of the model, and when you let it cool, the grand pattern is somewhat different. It is more stable; one arrives at a more globally consistent state. Your semantic-affective constraints are, on the whole, better satisfied. The Turings called this phenomenon qualia annealing.
Ising Model – A simple computational analogy for the LSD-induced global constraint satisfaction facilitation.
If one ups the dose a little bit and lands somewhere in the range between 4 to 8 mg, one is likely to experience what Terrence McKenna called “the Chrysanthemum”. This usually manifests as a surface saturated with a sort of textured fabric composed of intricate symmetrical relationships, bright colors, shifting edges and shimmering pulsing superposition patterns of harmonic linear waves of many different frequencies.
Depending on the dose consumed one may experience either one or several semi-parallel channels. Whereas a threshold dose usually presents you with a single strong vibe (or ambiance), the Chrysanthemum level often has several competing vibes each bidding for your attention. Here are some examples of what the visual component of this state of consciousness may look like.
Chrysanthemum with multuple symmetry channels
The visual component of the Chrysanthemum is often described as “the best screen saver ever“, and if you happen to experience it in a good mood you will almost certainly agree with that description, as it is usually extremely harmonious, symmetric and beautiful in uncountable ways. No external input can possibly replicate the information density and intricate symmetry of this state; such state has to be endogenously generated as a a sort of harmonic attractor of your brain dynamics.
You can find many replications of Chrysanthemum-level DMT experiences on the internet, and I encourage you to examine their implicit symmetries (this replication is one of my all-times favorite).
In Algorithmic Reduction of Psychedelic States we posited that any one of the 17 wallpaper symmetry groups can be instantiated as the symmetries that govern psychedelic visuals. Unfortunately, unlike the generally slow evolution of usual psychedelic visuals, DMT’s vibrational frequency forces such visuals to evolve at a speed that makes it difficult for most people to spot the implicit symmetry elements that give rise to the overall mathematical structure underneath one’s experience. For this reason it has been difficult to verify that all 17 wallpaper groups are possible in DMT states. Fortunately we were recently able to confirm that this is in fact the case thanks to someone who trained himself to do just this. I.e. detecting symmetry elements in patterns at an outstanding speed.
An anonymous psychonaut (whom we will call researcher A) sent a series of trip report to Qualia Computing detailing the mathematical properties of psychedelic visuals under various substances and dose regimens. A is an experienced psychonaut and a math enthusiast who recently trained himself to recognize (and name) the mathematical properties of symmetrical patterns (such as in works of art or biological organisms). In particular, he has become fluent at naming the symmetries exhibited by psychedelic visuals. In the context of 2D visuals on surfaces, A confirms that the symmetrical textures that arise in psychedelic states can exhibit any one of the 17 wallpaper symmetry groups. Likewise, he has been able to confirm that every possible spherical symmetry group can also be instantiated in one’s mind as a resonant attractor on these states.
The images below show some examples of the visuals that A has experienced on 2C-B, LSD, 4-HO-MET and DMT (sources: top left, top middle, the rest were made with this service):
The Chrysanthemum level interacts with sensory input in an interesting way: the texture of anything one looks at quickly becomes saturated with nested 2-dimensional symmetry groups. If you took enough DMT to take you to this level and you keep your eyes open and look at a patterned surface (i.e. statistical texture), it will symmetrify beyond recognition. A explains that at this level DMT visuals share some qualities with those of, say, LSD, mescaline, and psilocin. Like other psychedelics, DMT’s Chrysanthemum level can instantiate any 2-dimensional symmetry, yet there are important differences from other psychedelics at this dose range. These include the consistent change in ambiance (already present in threshold doses), the complexity and consistency of the symmetrical relationships (much more dense and whole-experience-consistent than is usually possible with other psychedelics), and the speed (with a control-interruption frequency reaching up to 30 hertz, compared to 10-20 hertz for most psychedelics). Thus, people tend to point out that DMT visuals (at this level) are “faster, smaller, more detailed and more globally consistent” than on comparable levels of alteration from similar agents.
Now, if you take a dose that is a little higher (in the ballpark of 8 to 12 mg), the Chrysanthemum will start doing something new and interesting…
(3) The Magic Eye Level
A great way to understand the Magic Eye level of DMT effects is to think of the Chrysanthemum as the texture of an autostereogram (colloquially described as “Magic Eye” pictures). Our visual experience can be easily decomposed into two points-of-view (corresponding to the feed coming from each eye) that share information in order to solve the depth-map problem in vision. This is to map each visual qualia to a space with relative distances so (a) the input is explained and (b) you get recognizable every-day objects represented as implicit shapes beneath the depth-map. You can think of this process as a sort of hand-shake between bottom-up perception and top-down modeling.
In everyday conditions one solves the depth-map problem within a second of opening one’s eyes (minus minor details that are added as one looks around). But on DMT, the “low-level perceptions” looks like a breathing Chrysanthemum, which means that the top-down modeling has that “constantly shifting” stuff to play with. What to make of it? Anything you can think of.
There are three major components of variance on the DMT Magic Eye level:
Texture (dependent on the Chrysanthemum’s evolution)
World-sheet (non-occluduing 3D1T depth maps)
Extremelly lowered information copying threshold.
The image on the left is a lobster, the one on the center is a cone and the one to the right contains furniture (a lamp, a chair and a table). Notice that what you see is a sort of depth-map which encodes shapes. We will call this depth-map together with the appearance of movement and acceleration represented in it, a world-sheet.
The world-sheet encodes the “semantic content” of the scene and is capable of representing arbitrary situations (including information about what you are seeing, where you are, what the entities there are doing, what is happening, etc.).
It is common to experience scenes from usually mundane-looking places like ice-cream stores, play pens, household situations, furniture rooms, apparel, etc.. Likewise, one frequently sees entities in these places, but they rarely seem to mind you because their world is fairly self-contained. As if seeing through a window. People often report that the worlds they saw on a DMT trip were all “made of the same thing”. This can be interpreted as the texture becoming the surfaces of the world-sheet, so that the surfaces of the tables, chairs, ice-cream cones, the bodies of the people, and so on are all patterned with the same texture (just as in actual autostereograms). This texture is indeed the Chrysanthemum completely contorted to accommodate all the curvature of the scene.
Magic Eye level scenes often include 3D geometrical shapes like spheres, cones, cylinders, cubes, etc. The complexity of the scene is roughly dose-dependent. As one ups the highness (but still remaining within the Magic Eye level) complex translucid qualia crystals in three dimensions start to become a possibility.
Whatever phenomenal objects you experience on this level that lives for more than a millisecond needs to have effective strategies for surviving in an ecosystem of other objects adapted to that level. Given the extremely lowered information copying threshold, whatever is good at making copies of itself will begin to tesselate, mutate and evolve, stealing as much of your attention as possible in the way. Cyclic transitions occupy one’s attention: objects quickly become scenes which quickly become gestalts from which a new texture evolves in which new objects are detected and so on ad infinitum.
A reports that at this dose range one can experience at least some of the 230 space groups as objects represented in the world-sheet. For example, A reports having stabilized a structure with a Pm-3m symmetry structure, not unlike the structure of ZIF-71-RHO. Visualizing such complex 3D symmetries, however, does seem to require previous training and high levels of mental concentration (i.e. in order to ensure that all the symmetry elements are indeed what they are supposed to be).
There is so much qualia laying around, though, at times not even your normal space can contain it all. Any regular or semi regular symmetrical structure you construct by centering your attention prone to overflow if you focus too much on it. What does this mean? If you focus too much on, for example, the number 6, your mind might represent the various ways in which you can arrange six balls in a perfectly symmetrical way. Worlds made of hexagons and octahedrons interlocked in complex but symmetrical ways may begin to tesselate your experiential field. With every second you find more and more ways of representing the number six in interesting, satisfying, metaphorically-sound synesthetic ways (cf. Thinking in Numbers). Now, what happens if you try to represent the number seven in a symmetric way on the plane? Well, the problem is that you will have too many heptagons to fit in Euclidean space (cf. Too Many Triangles). Thus the resulting symmetrical patterns will seem to overflow the plane (which is often felt as a folding and fluid re-arrangement, and when there is no space left in a region it either expands space or it is felt as some sort of synesthetic tension or stress, like a sense of crackling under a lot of pressure).
Heptagonal tiling of the Poincaré disk representing the 2D hyperbolic space.
Order-7-3 rhombille tiling
In particular, A claims that in the lower ranges of the DMT Magic Eye level the texture of the Chrysanthemum tends to exhibit heptagonal and triheptagonal tilings (as shown in the picture above). A explains that at the critical point between the Chrysanthemum and the Magic Eye levels the intensity of the rate of symmetry detection of the Chrysanthemum cannot be contained to a 2D surface. Thus, the surface begins to fold, often in semi-symmetric ways. Every time one “recognizes” an object on this “folding Chrysanthemum” the extra curvature is passed on to this object. As the dose increases, one interprets more and more of this extra curvature and ends up shaping a complex and highly dynamic spatiotemporal depth map with hyperbolic folds. In the upper ranges of the Magic Eye level the world-sheet is so curved that the scenes one visualize are intricate and expansive, feeling at times like one is able to peer through one’s horizon in all directions and see oneself and one’s world from a distance. At some critical point one may feel like the space around one is folding into a huge dome where the walls are made of whatever texture + world-sheet combination happened to win the Darwinian selection pressures applied to the qualia patterns on the Magic Eye level. This concentrated hyperbolic synesthetic texture is what becomes the walls of the Waiting Room…
As suggested by the quotes above, psychedelic symmetries are extremely beautiful. This is puzzling for most worldviews. But once you take into account the Tyranny of the Intentional Object and the Symmetry Theory of Valence, it begins to make sense why peak symmetry on psychedelics is so delightfully amazing (sometimes unimaginably better than a great orgasm or a back-rub on ecstasy). In this vein, we are proud to point out that we have worked out some precise, empirically testable, predictions based on connectome-specific harmonic waves and the symmetry theory of valence (see: Quantifying Bliss).
Interestingly, the process of point-of-view fragmentation and subsequent annealing to global geometric coherence is hinted at by John C. Lilly in his book Programming and Metaprogramming in the Human Biocomputer (you can read the relevant quote here: Psychedelic alignment cascades).
As evidenced in Steven Lehar’s writeup (and the other quotes and references provided above), we could say that giving psychedelics to brilliant people with a scientific background in cognitive science and natural philosophical talent does indeed have the ability to expand our evidential base for the nature of consciousness and the way our brains work.
It is thus far more useful for the advancement of the science of consciousness to allocate such experiences to serious scientifically-minded psychonauts than it is to give those same agents to people with pre-scientific frameworks. The phenomenological descriptions and insights provided by a single Steven Lehar on acid are worth a thousand Buddhists, French Existentialists, poets, and film-makers on LSD.
Either way, it is unconscionable that today most leading academics working on the problem of consciousness have no personal experience with these agents, nor they show much interest in the alien state-spaces that they disclose. That’s about as weird as physicists only showing interest in what happens at room-temperature, even though most precise mathematical theories of the physical world can only be tested in extreme conditions (such as high-energy particle collisions). Just as we can expect that a few observations of the behavior of matter in extreme conditions will provide a lot more information than thousands of observations of matter in known “everyday” conditions, the ultimate nature of qualia is most likely to be understood by studying its properties in extreme (e.g. high-energy) neuronal environments.
There’s an old Jewish childrens’ song called Had Gadya. It starts:
A little goat, a little goat My father bought for two silver coins, A little goat, a little goat
Then came the cat that ate the goat My father bought for two silver coins A little goat, a little goat
Then came that dog that bit the cat…
And so on. A stick hits the dog, a fire burns the stick, water quenches the fire, an ox drinks the water, a butcher slaughters the ox, the Angel of Death takes the butcher, and finally God destroys the Angel of Death. Throughout all of these verses, it is emphasized that it is indeed a little goat, and the father did indeed buy it for two silver coins.
As far as I know, no one has previously linked this song to the Lurianic Kabbalah. So I will say it: the deepest meaning of Had Gadya is a description of how and why God created the world. As an encore, it also resolves the philosophical problem of evil.
The most prominent Biblical reference to a goat is the scapegoating ritual. Once a year, the High Priest of Israel would get rid of the sins of the Jewish people by mystically transferring all of them onto a goat, then yelling at the goat until it ran off somewhere, presumably taking all the sin with it.
The thing is, at that point the goat contained an entire nation-year worth of sin. That goat was super evil. As a result, many religious and mystical traditions have associated unholy forces with goats ever since, from the goat demon Baphomet to the classical rather goat-like appearance of Satan.
So the goat represents evil. I’ll go along with everyone else saying the father represents God here. So God buys evil with two silver coins. What’s up?
The most famous question in theology is “Why did God create a universe filled with so much that is evil?” The classical answers tend to be kind of weaselly, and center around something like free will or necessary principles or mysterious ways. Something along the lines of “Even though God’s omnipotent, creating a universe without evil just isn’t possible.”
But here we have God buying evil with two silver coins. Buying to me represents an intentional action. Let’s go further – buying represents a sacrifice. Buying is when you sacrifice something dear to you to get something you want even more. Evil isn’t something God couldn’t figure out how to avoid, it’s something He covets.
What did God sacrifice for the sake of evil? Two silver coins. We immediately notice the number “two”. Two is not typically associated with God. God is One. Two is right out. The kabbalists identify the worst demon, the nadir of all demons, as Thamiel, whose name means “duality in God”. Two is dissonance, divorce, division, dilemmas, distance, discrimination, diabolism.
This, then, was God’s sacrifice. In order to create evil, He took up duality.
“Why would God want to create evil? God is pure Good!”
Exactly. The creation of anything at all other than God requires evil. God is perfect. Everything else is imperfect. Imperfection contains evil by definition. Two scoops of evil is the first ingredient in the recipe for creating universes. Finitude is evil. Form is evil. Without evil all you have is God, who, as the kabbalists tell us, is pure Nothing. If you want something, evil is part of the deal.
Now count the number of creatures in the song. God, angel, butcher, ox, water, fire, stick, dog, cat, goat. Ten steps from God to goat. This is the same description of the ten sephirot we’ve found elsewhere, the ten levels by which God’s ineffability connects to the sinful material world without destroying it. This is not a coincidence because nothing is ever a coincidence. Had Gadya isn’t just a silly children’s song about the stages of advancement of the human soul, the appropriate rituals for celebrating Passover in the Temple, the ancient Sumerian pantheon, and the historical conquests of King Tiglath-Pileser III. It’s also a blueprint for the creation of the universe. Just like everything else.

Title: Heuristics For Interpreting The Output Of Formal Panpsychist Theories Of Consciousness
Author: Michael E. Johnson
Primary Topic Area: Ontology of consciousness
Secondary Topic Area: Panpsychism, neutral monism, and idealism
Abstract: IIT, Orch-OR, Perceptronium, and other panpsychist approaches to formalizing consciousness have been gaining traction in recent years (Oizumi, Albantakis & Tononi 2014; Hameroff & Penrose 1996, 2014; Penrose & Hameroff 2011; Tegmark 2014; Barrett 2014). However, relatively little effort has been spent on interpreting the formal output of such theories. We briefly outline the problem, suggest four heuristics for addressing it, and offer the preliminary fruits of these heuristics, the Symmetry Theory of Valence. First, we offer that a theory of consciousness is “formal” insofar as it acts as an objective translation function, wherein one feeds in facts about a system, with the output result being a mathematical object isomorphic to the phenomenology of that system (Oizumi et al. 2014; Tsuchiya, Taguchi & Saigo 2016). As such, we can consider theoretical formality on a continuum, with IIT and Orch-OR on the ‘more formal’ end, and theories such as Global Workspace Theory on the ‘less formal’ end. However, even if progress continues apace and we settle on the correct method by which to objectively derive mathematical objects isomorphic to any system’s qualia, we’ll still be faced with the challenge of interpreting what such a formalism means: which features of this mathematical object correspond to which specific qualia (Balduzzi & Tononi 2009). To address this challenge, we take advantage of the bidirectional nature of the isomorphism and note that distinctions about the mathematical output of (e.g.) IIT or Orch-OR also apply to the qualia it represents and vice-versa; this gives us a framework for combining intuition and formal methods in order to reverse-engineer specific qualia. As a first pass, we offer that a quale (and its mathematical representation) can be (1) local vs global; (2) simple vs complex; (3) atomic vs composite; (4) intuitively important vs intuitively trivial. And so if we can determine that a given quale is e.g. global, simple, atomic, and intuitively important, so too is its mathematical representation, and vice-versa. Based on this analysis, we identify emotional valence, or the ‘hedonic gloss’ of experience (Frijda 2006, 2009; Aldridge & Berridge 2009; Ryle 1954) as a plausible first candidate for reverse-engineering (“the c. elegans of qualia”), and suggest the Symmetry Theory of Valence: given a mathematical object isomorphic to the phenomenology of a system, the property of that object which corresponds with how pleasant it is to be that system will be the object’s symmetry. Lastly, we extend this to empirical predictions and implications for the further development of Orch-OR and IIT.
Title: Quantifying Bliss With Microtubules And Brain Connectome Harmonics: Empirically Testable Hypotheses For Valence
Author: Andres Gomez Emilsson
Primary Topic Area: Emotion
Secondary Topic Area: Qualia
Abstract: What makes an experience blissful? Can bliss ever be quantified? Emotion is usually factored along two main axes: arousal (energy level) and valence (the pleasure-pain axis). High valence (i.e. highly blissful) states of consciousness include: orgasm, romantic love, deep sleep, concentration meditation (so-called “Jhana states”), psychedelic ecstasy, and so on. Low valence states include: depression, anxiety, bodily discomfort, and the experiential quality of listening to dissonance. Confusingly, we also experience neutral as well as mixed states of consciousness. An explanatory framework that ties together these disparate experiences in a coherent way is needed, such that valence becomes objectively quantifiable. Affective neuroscience classically addresses the question of “what makes an experience blissful” in terms of things such as neuroanatomical correlates (“pleasure center activation”), neurotransmitter and receptor function (“Mu-opioid activation”), and computational concepts (“reinforcement learning”). It is important to note that positive valence is associated with these features, but that does not, on its own, constitute a satisfying explanation. More so, counterexamples to such associations abound (unpleasant opioidergic states, reinforcement without pleasure, etc.) A scientific account of valence should be able to explain these associations and their exceptions, provide clear quantitative metrics for valence in arbitrary brain states, and, above all, make precise and testable (hopefully surprising) predictions. We advance a framework for studying consciousness that can deliver just that. We introduce the concepts of: Qualia Formalism (for any given conscious experience, there exists a mathematical object isomorphic to its phenomenology), Qualia Structuralism (this mathematical object has a rich set of formal structures), and Valence Realism (valence is a crisp phenomenon of conscious states upon which we can apply a measure). Based on this framework we propose the “Symmetry Theory of Valence” (STV): Given a mathematical object isomorphic to the qualia of a system, the mathematical property which corresponds to how pleasant it is to be that system is that object’s symmetry. We pair up the STV to various accounts of “the structural level at which valence takes place” and generate empirically testable predictions for each. Namely, we generate predictions for: (1) the protein and microtubule account introduced by Hameroff & Penrose (1996), (2) the “mental organs” account of states of consciousness proposed by Ray (2012), and (3) the connectome-specific harmonic account of brain states by Atasoy et al. (2016). In particular for (3), we arrive at an equation that transforms fMRI data into Consonance-Dissonance-Noise Signatures (CDNS) which, according to the STV, ought to account for a large fraction of the variance associated with valence. If experimentally verified, this equation would be the first fully quantitative account of valence derived from first principles capable of tying together the myriad kinds of bliss into a coherent framework.
Testable theories of the fundamental nature of pleasure? I’m in!
“Everyone takes the limits of his own vision for the limits of the world.” (Schopenhauer)
All that matters is the pleasure-pain axis. Pain and pleasure disclose the world’s inbuilt metric of (dis)value. Our overriding ethical obligation is to minimise suffering. After we have reprogrammed the biosphere to wipe out experience below “hedonic zero”, we should build a “triple S” civilisation based on gradients of superhuman bliss. The nature of ultimate reality baffles me. But intelligent moral agents will need to understand the multiverse if we are to grasp the nature and scope of our wider cosmological responsibilities. My working assumption is non-materialist physicalism. Formally, the world is completely described by the equation(s) of physics, presumably a relativistic analogue of the universal Schrödinger equation. Tentatively, I’m a wavefunction monist who believes we are patterns of qualia in a high-dimensional complex Hilbert space. Experience discloses the intrinsic nature of the physical: the “fire” in the equations. The solutions to the equations of QFT or its generalisation yield the values of qualia. What makes biological minds distinctive, in my view, isn’t subjective experience per se, but rather non-psychotic binding. Phenomenal binding is what consciousness is evolutionarily “for”. Without the superposition principle of QM, our minds wouldn’t be able to simulate fitness-relevant patterns in the local environment. When awake, we are quantum minds running subjectively classical world-simulations. I am an inferential realist about perception. Metaphysically, I explore a zero ontology: the total information content of reality must be zero on pain of a miraculous creation of information ex nihilo. Epistemologically, I incline to a radical scepticism that would be sterile to articulate. Alas, the history of philosophy twinned with the principle of mediocrity suggests I burble as much nonsense as everyone else.
Excerpt from Superintelligence: Paths, Dangers, Strategies (2014) by Nick Bostrom (pg. 207-210).
Would Maximally Efficient Work Be Fun?
One important variable in assessing the desirability of a hypothetical condition like this* is the hedonic state of the average emulation**. Would a typical emulation worker be suffering or would he be enjoying the experience of working hard on the task at hand?
We must resist the temptation to project our own sentiments onto the imaginary emulation worker. The question is not whether you would feel happy if you had to work constantly and never again spend time with your loved ones–a terrible fate, most would agree.
It is moderately more relevant to consider the current human average hedonic experience during working hours. Worldwide studies asking respondents how happy they are find that most rate themselves as “quite happy” or “very happy” (averaging 3.1 on a scale from 1 to 4)***. Studies on average affect, asking respondents how frequently they have recently experienced various positive or negative affective states, tend to get a similar result (producing a net affect of about 0.52 on a scale from -1 to 1). There is a modest positive effect of a country’s per capita income on average subjective well-being.**** However, it is hazardous to extrapolate from these findings to the hedonic state of future emulation workers. One reason that could be given for this is that their condition would be so different: on the one hand, they might be working much harder; on the other hand, they might be free from diseases, aches, hunger, noxious odors, and so forth. Yet such considerations largely miss the mark. The much more important consideration here is that hedonic tone would be easy to adjust through the digital equivalent of drugs or neurosurgery. This means that it would be a mistake to infer the hedonic state of future emulations from the external conditions of their lives by imagining how we ourselves and other people like us would feel in those circumstances. Hedonic state would be a matter of choice. In the model we are currently considering, the choice would be made by capital-owners seeking to maximize returns on their investment in emulation-workers. Consequently, this question of how happy emulations would feel boils down to the question of which hedonic states would be most productive (in the various jobs that emulations would be employed to do). [Emphasis mine]
Here, again, one might seek to draw an inference from observations about human happiness. If it is the case, across most times, places, and occupations, that people are typically at least moderately happy, this would create some presumption in favor of the same holding in a post-transition scenario like the one we are considering. To be clear, the argument in this case would not be that human minds have a predisposition towards happiness so they would probably find satisfaction under these novel conditions; but rather that a certain average level of happiness has proved adaptive for human minds in the past so maybe a similar level of happiness will prove adaptive from human-like minds in the future. Yet this formulations also reveals the weakness of the inference: to wit, that the mental dispositions that were adaptive for hunter-gatherer hominids roaming the African savanna may not necessarily be adaptive for modified emulations living in post-transition virtual realities. We can certainly hope that the future emulation-workers would be as happy as, or happier than, typical workers were in human history; but we have yet to see any compelling reason for supposing it would be so (in the laissez-faire multipolar scenario currently under examination).
Consider the possibility that the reason happiness is prevalent among humans (to whatever limited extent it is prevalent) is that cheerful mood served a signaling function in the environment of evolutionary adaptedness. Conveying the impression to other members of the social group of being in flourishing condition–in good health, in good standing with one’s peers, and in confident expectation of continued good fortune–may have boosted an individual’s popularity. A bias toward cheerfulness could thus have been selected for, with the result that human neurochemistry is now biased toward positive affect compared to what would have been maximally efficient according to simpler materialistic criteria. If this were the case, then the future of joie de vivre might depend on cheer retaining its social signaling function unaltered in the post-transition world: an issue to which we will return shortly.
What if glad souls dissipate more energy than glum ones? Perhaps the joyful are more prone to creative leaps and flights of fancy–behaviors that future employers might disprize in most of their workers. Perhaps a sullen or anxious fixation on simply getting on with the job without making mistakes will be the productivity-maximizing attitude in most lines of work. The claim here is not that this is so, but that we do not know that it is not so. Yet we should consider just how bad it could be if some such pessimistic hypothesis about a future Malthusian state turned out to be true: not only because of the opportunity cost of having failed to create something better–which would be enormous–but also because the state could be bad in itself, possibly far worse that the original Malthusian state.
We seldom put forth full effort. When we do, it is sometimes painful. Imagine running on a treadmill at a steep incline–heart pounding, muscles aching, lungs gasping for air. A glance at the timer: your next break, which will will also be your death, is due in 49 years, 3 months, 20 days, 4 hours, 56 minutes, and 12 seconds. You wish you had not been born.
Again the claim is not that this is how it would be, but that we do not know that it is not. One could certainly make a more optimistic case. For example, there is no obvious reason that emulations would need to suffer bodily injury and sickness: the elimination of physical wretchedness would be a great improvement over the present state of affairs. Furthermore, since such stuff as virtual reality is made of can be fairly cheap, emulations may work in sumptuous surroundings–in splendid mountaintop palaces, on terraces set in a budding spring forest, or on the beaches of azure lagoon–with just the right illumination, temperature, scenery and décor; free from annoying fumes, noises, drafts, and buzzing insects; dressed in comfortable clothing, feeling clean and focused, and well nourished. More significantly, if–as seems perfectly possible–the optimum human mental state for productivity in most jobs is one of joyful eagerness, then the era of the emulation economy could be quite paradisiacal.
There would, in any case, be a great option value in arranging matters in such a manner that somebody or something could intervene to set things right if the default trajectory should happen to veer toward dystopia. It could also be desirable to have some sort of escape hatch that would permit bailout into death and oblivion if the quality of life were to sink permanently below the level at which annihilation becomes preferable to continued existence.
In the long run, as the emulation era gives way to an artificial intelligence era (or if machine intelligence is attained directly via AI without a preceding whole brain emulation stage) pain and pleasure might possibility disappear entirely in a multipolar outcome, since a hedonic reward mechanism may not be the most effective motivation system for a complex artificial agent (one that, unlike the human mind, is not burdened with the legacy of animal wetware). Perhaps a more advanced motivation system would be based on an explicit representation of a utility function or some other architecture that has not exact functional analogs to pleasure and pain.
A related but slightly more radical multipolar outcome–one that could involve the elimination of almost all value from the future–is that the universal proletariat would not even be conscious. This possibility is most salient with respect to AI, which might be structured very differently than human intelligence. But even if machine intelligence were initially achieved through whole brain emulation, resulting in conscious digital minds, the competitive forces unleashed in a post-transition economy could easily lead to the emergence of progressively less neuromorphic forms of machine intelligence, either because synthetic AI is created de novo or because the emulations would, through successive modifications and enhancements, increasingly depart their original human form.
* Scenarios where sentient emulations are being used to do maximally efficient work.
** Footnote: “An ethical evaluation might take into account many other factors as well. Even if all the workers were constantly well pleased with their condition, the outcome might still be deeply morally objectionable on other grounds–though which other grounds is a matter of dispute between rival moral theories. But any plausible assessment would consider subjective well-being to be one important factor. See also Bostrom and Yudkowsky (2015).”
“It seems plain and self-evident, yet it needs to be said: the isolated knowledge obtained by a group of specialists in a narrow field has in itself no value whatsoever, but only in its synthesis with all the rest of knowledge and only inasmuch as it really contributes in this synthesis toward answering the demand, ‘Who are we?'”
– Erwin Schrödinger in Science and Humanism (1951)
“Should you or not commit suicide? This is a good question. Why go on? And you only go on if the game is worth the candle. Now, the universe is been going on for an incredibly long time. Really, a satisfying theory of the universe should be one that’s worth betting on. That seems to me to be absolutely elementary common sense. If you make a theory of the universe which isn’t worth betting on… why bother? Just commit suicide. But if you want to go on playing the game, you’ve got to have an optimal theory for playing the game. Otherwise there’s no point in it.”
In this article we provide a novel framework for ethics which focuses on the perennial battle between wellbeing-oriented consciousness-centric values and valueless patterns who happen to be great at making copies of themselves (aka. Consciousness vs. Pure Replicators). This framework extends and generalizes modern accounts of ethics and intuitive wisdom, making intelligible numerous paradigms that previously lived in entirely different worlds (e.g. incongruous aesthetics and cultures). We place this worldview within a novel scale of ethical development with the following levels: (a) The Battle Between Good and Evil, (b) The Balance Between Good and Evil, (c) Gradients of Wisdom, and finally, the view that we advocate: (d) Consciousness vs. Pure Replicators. More so, we analyze each of these worldviews in light of our philosophical background assumptions and posit that (a), (b), and (c) are, at least in spirit, approximations to (d), except that they are less lucid, more confused, and liable to exploitation by pure replicators. Finally, we provide a mathematical formalization of the problem at hand, and discuss the ways in which different theories of consciousness may affect our calculations. We conclude with a few ideas for how to avoid particularly negative scenarios.
Throughout human history, the big picture account of the nature, purpose, and limits of reality has evolved dramatically. All religions, ideologies, scientific paradigms, and even aesthetics have background philosophical assumptions that inform their worldviews. One’s answers to the questions “what exists?” and “what is good?” determine the way in which one evaluates the merit of beings, ideas, states of mind, algorithms, and abstract patterns.
Kuhn’s claim that different scientific paradigms are mutually unintelligible (e.g. consciousness realism vs. reductive eliminativism) can be extended to worldviews in a more general sense. It is unlikely that we’ll be able to convey the Consciousness vs. Pure Replicators paradigm by justifying each of the assumptions used to arrive to it one by one starting from current ways of thinking about reality. This is because these background assumptions support each other and are, individually, not derivable from current worldviews. They need to appear together as a unit to hang together tight. Hence, we now make the jump and show you, without further due, all of the background assumptions we need:
These assumptions have been discussed in previous articles. In the meantime, here is a brief description: (1) is the claim that consciousness is an element of reality rather than simply the improper reification of illusory phenomena, such that your conscious experience right now is as much a factual and determinate aspect of reality as, say, the rest mass of an electron. In turn, (2) qualia formalism is the notion that consciousness is in principle quantifiable. Assumption (3) states that valence (i.e. the pleasure/pain axis, how good an experience feels) depends of the structure of such experience (more formally, on the properties of the mathematical object isomorphic to its phenomenology).
(4) is the assumption that people’s behavior is motivated by the pleasure-pain axis even when they think that’s not the case. For instance, people may explicitly represent the reason for doing things in terms of concrete facts about the circumstance, and the pleasure principle does not deny that such reasons are important. Rather, it merely says that such reasons are motivating because one expects/anticipates less negative valence or more positive valence. The Tyranny of the Intentional Object describes the fact that we attribute changes in our valence to external events and objects, and believe that such events and objects are intrinsically good (e.g. we think “icecream is great” rather than “I feel good when I eat icecream”).
Physicalism (5) in this context refers to the notion that the equations of physics fully describe the causal behavior of reality. In other words, the universe behaves according to physical laws and even consciousness has to abide by this fact.
Open Individualism (6) is the claim that we are all one consciousness, in some sense. Even though it sounds crazy at first, there are rigorous philosophical arguments in favor of this view. Whether this is true or not is, for the purpose of this article, less relevant than the fact that we can experience it as true, which happens to have both practical and ethical implications for how society might evolve.
Finally, (7) Universal Darwinism refers to the claim that natural selection works at every level of organization. The explanatory power of evolution and fitness landscapes generated by selection pressures is not confined to the realm of biology. Rather, it is applicable all the way from the quantum foam to, possibly, an ecosystem of universes.
The power of a given worldview is not only its capacity to explain our observations about the inanimate world and the quality of our experience, but also in its capacity to explain *in its own terms* the reasons for why other worldviews are popular as well. In what follows we will utilize these background assumptions to evaluate other worldviews.
The Four Worldviews About Ethics
The following four stages describe a plausible progression of thoughts about ethics and the question “what is valuable?” as one learns more about the universe and philosophy. Despite the similarity of the first three levels to the levels of other scales of moral development (e.g. this, this, this, etc.), we believe that the fourth level is novel, understudied, and very, very important.
1. The “Battle Between Good and Evil” Worldview
“Every distinction wants to become the distinction between good and evil.” – Michael Vassar (source)
Common-sensical notions of essential good and evil are pre-scientific. For reasons too complicated to elaborate on for the time being, the human mind is capable of evoking an agentive sense of ultimate goodness (and of ultimate evil).
Good vs. Evil? God vs. the Devil?
Children are often taught that there are good people and bad people. That evil beings exist objectively, and that it is righteous to punish them and see them with scorn. On this level people reify anti-social behaviors as sins.
Essentializing good and evil, and tying it up to entities seems to be an early developmental stage of people’s conception of ethics, and many people end up perpetually stuck in here. Several religions (specially the Abrahamic ones) are often practiced in such a way so as to reinforce this worldview. That said, many ideologies take advantage of the fact that a large part of the population is at this level to recruit adherents by redefining “what good and bad is” according to the needs of such ideologies. As a psychological attitude (rather than as a theory of the universe), reactionary and fanatical social movements often rely implicitly on this way of seeing the world, where there are bad people (jews, traitors, infidels, over-eaters, etc.) who are seen as corrupting the soul of society and who deserve to have their fundamental badness exposed and exorcised with punishment in front of everyone else.
Traditional notions of God vs. the Devil can be interpreted as the personification of positive and negative valence
Implicitly, this view tends to gain psychological strength from the background assumptions of Closed Individualism (which allows you to imagine that people can be essentially bad). Likewise, this view tends to be naïve about the importance of valence in ethics. Good feelings are often interpreted as the result of being aligned with fundamental goodness, rather than as positive states of consciousness that happen to be triggered by a mix of innate and programmable things (including cultural identifications). More so, good feelings that don’t come in response to the preconceived universal order are seen as demonic and aberrant.
From our point of view (the 7 background assumptions above) we interpret this particular worldview as something that we might be biologically predisposed to buy into. Believing in the battle between good and evil was probably evolutionarily adaptive in our ancestral environment, and might reduce many frictional costs that arise from having a more subtle view of reality (e.g. “The cheaper people are to model, the larger the groups that can be modeled well enough to cooperate with them.” – Michale Vassar). Thus, there are often pragmatic reasons to adopt this view, specially when the social environment does not have enough resources to sustain a more sophisticated worldview. Additionally, at an individual level, creating strong boundaries around what is or not permissible can be helpful when one has low levels of impulse control (though it may come at the cost of reduced creativity).
On this level, explicit wireheading (whether done right or not) is perceived as either sinful (defying God’s punishment) or as a sort of treason (disengaging from the world). Whether one feels good or not should be left to the whims of the higher order. On the flipside, based on the pleasure principle it is possible to interpret the desire to be righteous as being motivated by high valence states, and reinforced by social approval, all the while the tyranny of the intentional object cloaks this dynamic.
TVTropes has a great summary of the sorts of narratives that express this particular worldview and I highly recommend reading that article to gain insight into the moral attitudes compatible with this view. For example, here are some reasons why Good cannot or should not win:
Good winning includes: the universe becoming boring, society stagnating or collapsing from within in the absence of something to struggle against or giving people a chance to show real nobility and virtue by risking their lives to defend each other. Other times, it’s enforced by depicting ultimate good as repressive (often Lawful Stupid), or by declaring concepts such as free will or ambition as evil. In other words “too much of a good thing”.
Now, the stated reasons why people might buy into this view are rarely their true reasons. Deep down, the Balance Between Good and Evil is adopted because: people want to differentiate themselves from those who believe in (1) to signal intellectual sophistication, they experience learned helplessness after trying to defeat evil without success (often in the form of resilient personal failings or societal flaws), they find the view compelling at an intuitive emotional level (i.e. they have internalized the hedonic treadmill and project it onto the rest of reality).
In all of these cases, though, there is something somewhat paradoxical about holding this view. And that is that people report that coming to terms with the fact that not everything can be good is itself a cause of relief, self-acceptance, and happiness. In other words, holding this belief is often mood-enhancing. One can also confirm the fact that this view is emotionally load-bearing by observing the psychological reaction that such people have to, for example, bringing up the Hedonistic Imperative (which asserts that eliminating suffering without sacrificing anything of value is scientifically possible), indefinite life extension, or the prospect of super-intelligence. Rarely are people at this level intellectually curious about these ideas, and they come up with excuses to avoid looking at the evidence, however compelling it may be.
For example, some people are lucky enough to be born with a predisposition to being hyperthymic (which, contrary to preconceptions, does the opposite of making you a couch potato). People’s hedonic set-point is at least partly genetically determined, and simply avoiding some variants of the SCN9A gene with preimplantation genetic diagnosis would greatly reduce the number of people who needlessly suffer from chronic pain.
But this is not seen with curious eyes by people who hold this or the previous worldview. Why? Partly this is because it would be painful to admit that both oneself and others are stuck in a local maxima of wellbeing and that examining alternatives might yield very positive outcomes (i.e. omission bias). But at its core, this willful ignorance can be explained as a consequence of the fact that people at this level get a lot of positive valence from interpreting present and past suffering in such a way that it becomes tied to their core identity. Pride in having overcome their past sufferings, and personal attachment to their current struggles and anxieties binds them to this worldview.
If it wasn’t clear from the previous paragraph, this worldview often requires a special sort of chronic lack of self-insight. It ultimately relies on a psychological trick. One never sees people who hold this view voluntarily breaking their legs, taking poison, or burning their assets to increase the goodness elsewhere as an act of altruism. Instead, one uses this worldview as a mood-booster, and in practice, it is also susceptible to the same sort of fanaticism as the first one (although somewhat less so). “There can be no light without the dark. And so it is with magic. Myself, I always try to live within the light.” – Horace Slughorn.
Additionally, this view helps people rationalize the negative aspects of one’s community and culture. For example, it not uncommon for people to say that buying factory farmed meat is acceptable on the grounds that “some things have to die/suffer for others to live/enjoy life.” Balance Between Good and Evil is a close friend of status quo bias.
Hinduism, Daoism, and quite a few interpretations of Buddhism work best within this framework. Getting closer to God and ultimate reality is not done by abolishing evil, but by embracing the unity of all and fostering a healthy balance between health and sickness.
It’s also worth noting that the balance between good and evil tends to be recursively applied, so that one is not able to “re-define our utility function from ‘optimizing the good’ to optimizing ‘the balance of good and evil’ with a hard-headed evidence-based consequentialist approach.” Indeed, trying to do this is then perceived as yet another incarnation of good (or evil) which needs to also be balanced with its opposite (willful ignorance and fuzzy thinking). One comes to the conclusion that it is the fuzzy thinking itself that people at this level are after: to blur reality just enough to make it seem good, and to feel like one is not responsible for the suffering in the world (specially by inaction and lack of thinking clearly about how one could help). “Reality is only a Rorschach ink-blot, you know” – Alan Watts. So this becomes a justification for thinking less than one really has to about the suffering in the world. Then again, it’s hard to blame people for trying to keep the collective standards of rigor lax, given the high proportion of fanatics who adhere to the “battle between good and evil” worldview, and who will jump the gun to demonize anyone who is slacking off and not stressed out all the time, constantly worrying about the question “could I do more?”
David Chapman’s HTML book Meaningness might describe both of the previous worldviews as variants of eternalism. In the context of his work, eternalism refers to the notion that there is an absolute order and meaning to existence. When applied to codes of conduct, this turns into “ethical eternalism”, which he defines as: “the stance that there is a fixed ethical code according to which we should live. The eternal ordering principle is usually seen as the source of the code.” Chapman eloquently argues that eternalism has many side effects, including: deliberate stupidity, attachment to abusive dynamics, constant disappointment and self-punishment, and so on. By realizing that, in some sense, no one knows what the hell is going on (and those who do are just pretending) one takes the first step towards the “Gradients of Wisdom” worldview.
At this level people realize that there is no evil essence. Some might talk about this in terms of there “not being good or bad people”, but rather just degrees of impulse control, knowledge about the world, beliefs about reality, emotional stability, and so on. A villain’s soul is not connected to some kind of evil reality. Rather, his or her actions can be explained by the causes and conditions that led to his or her psychological make-up.
Sam Harris’ ideas as expressed in The Moral Landscape evoke this stage very clearly. Sam explains that just as health is a fuzzy but important concept, so is psychological wellbeing, and that for such a reason we can objectively assess cultures as more or less in agreement with human flourishing.
Indeed, many people who are at this level do believe in valence structuralism, where they recognize that there are states of consciousness that are inherently better in some intrinsic subjective value sense than others.
However, there is usually no principled framework to assess whether a certain future is indeed optimal or not. There is little hard-headed discussion of population ethics for fear of sounding unwise or insensitive. And when push comes to shove, they lack good arguments to decisively rule out why particular situations might be bad. In other words, there is room for improvement, and such improvement might eventually come from more rigor and bullet-bitting. In particular, a more direct examination of the implications of: Open Individualism, the Tyranny of the Intentional Object, and Universal Darwinism can allow someone on this level to make a breakthrough. Here is where we come to:
4. The “Consciousness vs. Pure Replicators” Worldview
I will define a pure replicator, in the context of agents and minds, to be an intelligence that is indifferent towards the valence of its conscious states and those of others. A pure replicator invests all of its energy and resources into surviving and reproducing, even at the cost of continuous suffering to themselves or others. Its main evolutionary advantage is that it does not need to spend any resources making the world a better place.
Presumably our genes are pure replicators. But we, as sentient minds who recognize the intrinsic value (both positive and negative) of conscious experiences, are not pure replicators. Thanks to a myriad of fascinating dynamics, it so happened that making minds who love, appreciate, think creatively, and philosophize was a side effect of the process of refining the selfishness of our genes. We must not take for granted that we are more than pure replicators ourselves, and that we care both about our wellbeing and the wellbeing of others. The problem now is that the particular selection pressures that led to this may not be present in the future. After all, digital and genetic technologies are drastically changing the fitness landscape for patterns that are good at making copies of themselves.
In an optimistic scenario, future selection pressures will make us all naturally gravitate towards super-happiness. This is what David Pearce posits in his essay “The Biointelligence Explosion”:
As the reproductive revolution of “designer babies” gathers pace, prospective parents will pre-select alleles and allelic combinations for a new child in anticipation of their behavioural effects – a novel kind of selection pressure to replace the “blind” genetic roulette of natural selection. In time, routine embryo screening via preimplantation genetic diagnosis will be complemented by gene therapy, genetic enhancement and then true designer zygotes. In consequence, life on Earth will also become progressively happier as the hedonic treadmill is recalibrated. In the new reproductive era, hedonic set-points and intelligence alike will be ratcheted upwards in virtue of selection pressure. For what parent-to-be wants to give birth to a low-status depressive “loser”? Future parents can enjoy raising a normal transhuman supergenius who grows up to be faster than Usain Bolt, more beautiful than Marilyn Monroe, more saintly than Nelson Mandela, more creative than Shakespeare – and smarter than Einstein.
In a pessimistic scenario, the selection pressures lead to the opposite direction, where negative experiences are the only states of consciousness that happen to be evolutionarily adaptive, and so they become universally used.
There is at least some encouraging facts that suggest it is not too late to prevent a pure replicator takeover. There are memes, states of consciousness, and resources that can be used in order to steer evolution in a positive directions. In particular, as of 2017:
There is a large fraction of the population who is altruistic and would be willing to cooperate with the rest of the world to avoid catastrophic scenarios.
Happy people are more motivated, productive, engaged, and ultimately, economically useful (see hyperthimic temperament).
Many people have explored Open Individualism and are interested (or at least curious) about the idea that we are all one.
A lot of people are fascinated by psychedelics and the non-ordinary states of consciousness that they induce.
MDMA-like consciousness is both very positive in terms of its valence, but also, amazingly, extremely pro-social, and future sustainable versions of it could be recruited to stabilize societies where the highest value is the collective wellbeing.
It is important to not underestimate the power of the facts laid out above. If we get our act together and create a Manhattan Project of Consciousness we might be able to find sustainable, reliable, and powerful methods that stabilize a hyper-motivated, smart, super-happy and super-prosocial state of consciousness in a large fraction of the population. In the future, we may all by default identify with consciousness itself rather than with our bodies (or our genes), and be intrinsically (and rationally) motivated to collaborate with everyone else to create as much happiness as possible as well as to eradicate suffering with technology. And if we are smart enough, we might also be able to solidify this state of affairs, or at least shield it against pure replicator takeovers.
The beginnings of that kind of society may already be underway. Consider for example the contrast between Burning Man and Las Vegas. Burning Man is a place that works as a playground for exploring post-Darwinean social dynamics, in which people help each other overcome addictions and affirm their commitment to helping all of humanity. Las Vegas, on the other hand, might be described as a place that is filled to the top with pure replicators in the forms of memes, addictions, and denial. The present world has the potential for both kind of environments, and we do not yet know which one will outlive the other in the long run.
Formalizing the Problem
We want to specify the problem in a way that will make it mathematically intelligible. In brief, in this section we focus on specifying what it means to be a pure replicator in formal terms. Per the definition, we know that pure replicators will use resources as efficiently as possible to make copies of themselves, and will not care about the negative consequences of their actions. And in the context of using brains, computers, and other systems whose states might have moral significance (i.e. they can suffer), they will simply care about the overall utility of such systems for whatever purpose they may require. Such utility will be a function of both the accuracy with which the system performs it’s task, as well as its overall efficiency in terms of resources like time, space, and energy.
Simply phrased, we want to be able to answer the question: Given a certain set of constraints such as energy, matter, and physical conditions (temperature, radiation, etc.), what is the amount of pleasure and pain involved in the most efficient implementation of a given predefined input-output mapping?
The image above represents the relevant components of a system that might be used for some purpose by an intelligence. We have the inputs, the outputs, the constraints (such as temperature, materials, etc.) and the efficiency metrics. Let’s unpack this. In the general case, an intelligence will try to find a system with the appropriate trade-off between efficiency and accuracy. We can wrap up this as an “efficiency metric function”, e(o|i, s, c) which encodes the following meaning: “e(o|i, s, c) = the efficiency with which a given output is generated given the input, the system being used, and the physical constraints in place.”
Now, we introduce the notion of the “valence for the system given a particular input” (i.e. the valence for the system’s state in response to such an input). Let’s call this v(s|i). It is worth pointing out that whether valence can be computed, and whether it is even a meaningfully objective property of a system is highly controversial (e.g. “Measuring Happiness and Suffering“). Our particular take (at QRI) is that valence is a mathematical property that can be decoded from the mathematical object whose properties are isomorphic to a system’s phenomenology (see: Principia Qualia: Part II – Valence, and also Quantifying Bliss). If so, then there is a matter of fact about just how good/bad an experience is. For the time being we will assume that valence is indeed quantifiable, given that we are working under the premise of valence structuralism (as stated in our list of assumptions). We thus define the overall utility for a given output as U(e(o|i, s, c), v(s|i)), where the valence of the system may or may not be taken into account. In turn, an intelligence is said to be altruistic if it cares about the valence of the system in addition to its efficiency, so that it’s utility function penalizes negative valence (and rewards positive valence).
Now, the intelligence (altruistic or not) utilizing the system will also have to take into account the overall range of inputs the system will be used to process in order to determine how valuable the system is overall. For this reason, we define the expected value of the system as the utility of each input multiplied by its probability.
(Note: a more complete formalization would also weight in the importance of each input-output transformation, in addition to their frequency). Moving on, we can now define the overall expected utility for the system given the distribution of inputs it’s used for, its valence, its efficiency metrics, and its constraints as E[U(s|v, e, c, P(I))]:
The last equation shows that the intelligence would choose the system that maximizes E[U(s|v, e, c, P(I))].
Pure replicators will be better at surviving as long as the chances of reproducing do not depend on their altruism. If altruism does not reduce such reproductive fitness, then:
Given two intelligences that are competing for existence and/or resources to make copies of themselves and fight against other intelligences, there is going to be a strong incentive to choose a system that maximizes the efficiency metrics regardless of the valence of the system.
In the long run, then, we’d expect to see only non-altruistic intelligences (i.e. intelligences with utility functions that are indifferent to the valence of the systems it uses to process information). In other words, as evolution pushes intelligences to optimize the efficiency metrics of the systems they employ, it also pushes them to stop caring about the wellbeing of such systems. In other words, evolution pushes intelligences to become pure replicators in the long run.
Hence we should ask: How can altruism increase the chances of reproduction? A possibility would be for the environment to reward entities that are altruistic. Unfortunately, in the long run we might see that environments that reward altruistic entities produce less efficient entities than environments that don’t. If there are two very similar environments, one which rewards altruism and one which doesn’t, the efficiency of the entities in the latter might become so much higher than in the former that they become able to takeover and destroy whatever mechanism is implementing such reward for altruism in the former. Thus, we suggest to find environments in which rewarding altruism is baked into their very nature, such that similar environments without such reward either don’t exist or are too unstable to exist for the amount of time it takes to evolve non-altruistic entities. This and other similar approaches will be explored further in Part II.
A key insight is that the formalization presented above is agnostic about one’s theory of consciousness. We are simply assuming that it’s possible to compute the valence of the system in terms of its state. How one goes about computing such valence, though, will depend on how one maps physical systems to experiences. Getting into the weeds of the countless theories of consciousness out there would not be very productive at this stage, but there is still value in defining the rough outline of kinds of theories of consciousness. In particular, we categorize (physicalist) theories of consciousness in terms of the level of abstraction they identify as the place in which to look for consciousness.
Behaviorism and similar accounts simply associate consciousness to input-output mappings, which can be described, in Marr’s terms, as the computational level of abstraction. In this case, v(s|i) would not depend on the details of the system as much as in what it does from a third person point of view. Behaviorists don’t care what’s in the Chinese Room; all they care about is if the Chinese Room can scribble “I’m in pain” as an output. How we can formalize a mathematical equation to infer whether a system is suffering from a behaviorist point of view is beyond me, but maybe someone might want to give it a shot. As a side note, behaviorists historically were not very concerned about pain or pleasure, and there cause to believe that behaviorism itself might be anti-depressant for people for whom introspection results in more pain than pleasure.
Functionalism (along with computational theories of mind) defines consciousness as the sum-total of the functional properties of systems. In turn, this means that consciousness arises at the algorithmic level of abstraction. Contrary to common misconception, functionalists do care about how the Chinese Room is implemented: contra behaviorists, they do not usually agree that a Chinese Room implemented with a look-up table is conscious.*
As such v(s|i) will depend on the algorithms that the system is implementing. Thus, as an intermediary step, one would need a function that takes the system as an input and returns the algorithms that the system is implementing as an output, A(s). Only once we have A(s) we would then be able to infer the valence of the system. Which algorithms, and for what reason, are in fact hedonically-charged has yet to be clarified. Committed functionalists often associate reinforcement learning with pleasure and pain, and one could imagine that as philosophy of mind gets more rigorous and takes into account more advancements in neuroscience and AI, we will see more hypothesis being made about what kinds of algorithms result in phenomenal pain (and pleasure). There are many (still fuzzy) problems to be solved for this account to work even in principle. Indeed, there is a reason to believe that the question “what algorithms is this system performing?” has no definite answer, and it surely isn’t frame-invariant in the same way that a physical state might be. The fact that algorithms do not carve nature at its joints would imply that consciousness is not really a well-defined element of reality either. But rather than this working as a reductio-ad-absurdum of functionalism, many of its proponents have instead turned around to conclude that consciousness itself is not a natural kind. This does represent an important challenge in order to define the valence of the system, and makes the problem of detecting and avoiding pure replicators extra challenging. Admirably so, this is not stopping some from trying anyway.
Finally, Non-Materialist Physicalism locates consciousness at the implementation level of abstraction. This general account of consciousness refers to the notion that the intrinsic nature of the physical is qualia. There are many related views that for the purpose of this article should be good enough approximations: panpsychism, panexperientialism, neutral monism, Russellian monism, etc. Basically, this view takes seriously both the equations of physics and the idea that what they describe is the behavior of qualia. A big advantage of this view is that there is a matter-of-fact about what a system is composed of. Indeed, both in relativity and quantum mechanics, the underlying nature of a system is frame-invariant, such that its fundamental (intrinsic and causal) properties do not depend on one’s frame of reference. In order to obtain v(s|i) we will need to obtain this frame-invariant description of what the system is in a given state. Thus, we need a function that takes as input physical measurements of the system and returns the best possible approximation to what is actually going on under the hood, Ph(s). And only with this function Ph(s) we would be ready to compute the valence of the system. Now, in practice we might not need a plank-length description of the system, since the mathematical property that describes it’s valence might turn out to be well-approximated with high-level features of it.
The main problem with Non-Materialist Physicalism comes when one considers systems that have similar efficiency metrics, are performing the same algorithms, and look the same in all of the relevant respects from a third-person point, and yet do not have the same experience. In brief: if physical rather than functional aspects of systems map to conscious experiences, it seems likely that we could find two systems that do the same (input-output mapping), do it in the same way (algorithms), and yet one is conscious and the other isn’t.
This kind of scenario is what has pushed many to conclude that functionalism is the only viable alternative, since at this point consciousness would seem epiphenomenal (e.g. Zombies Redacted). And indeed, if this was the case, it would seem to be a mere matter of chance that our brains are implemented with the right stuff to be conscious, since the nature of such stuff is not essential to the algorithms that actually end up processing the information. You cannot speak to stuff, but you can speak to an algorithm. So how do we even know we have the right stuff to be conscious?
The way to respond to this very valid criticism is for Non-Materialist Physicalism to postulate that bound states of consciousness have computational properties. In brief, epiphenomenalism cannot be true. But this does not rule out Non-Materialist Physicalism for the simple reason that the quality of states of consciousness might be involved in processing information. Enter…
The Computational Properties of Consciousness
Let’s leave behaviorism behind for the time being. In what ways do functionalism and non-materialist physicalism differ in the context of information processing? In the former, consciousness is nothing other than certain kinds of information processing, whereas in the latter conscious states can be used for information processing. An example of this falls out of taking David Pearce’s theory of consciousness seriously. In his account, the phenomenal binding problem (i.e. “if we are made of atoms, how come our experience contains many pieces of information at once?”, see: The Combination Problem for Panpsychism) is solved via quantum coherence. Thus, a given moment of consciousness is a definite physical system that works as a unit. Conscious states are ontologically unitary, and not merely functionally unitary.
If this is the case, there would be a good reason for evolution to recruit conscious states to process information. Simply put, given a set of constraints, using quantum coherence might be the most efficient way to solve some computational problems. Thus, evolution might have stumbled upon a computational jackpot by creating neurons whose (extremely) fleeting quantum coherence could be used to solve constraint satisfaction problems in ways that would be more energetically expensive to do otherwise. In turn, over many millions of years, brains got really good at using consciousness in order to efficiently process information. It is thus not an accident that we are conscious, that our conscious experiences are unitary, that our world-simulations use a wide range of qualia varieties, and so on. All of these seemingly random, seemingly epiphenomenal, aspects of our existence happen to be computationally advantageous. Just as using quantum computing for factorizing prime numbers, or for solving problems amenable to annealing might give quantum computers a computational edge over their non-quantum counterparts, so is using bound conscious experiences helpful to outcompete non-sentient animals.
Of course, there is yet no evidence of macroscopic decoherence and the brain is too hot anyway, so on the face of it Pearce’s theory seems exceedingly unlikely. But its explanatory power should not be dismissed out of hand, and the fact that it makes empirically testable predictions is noteworthy (how often do consciousness theorists make precise predictions to falsify their theories?).
Whether it is via quantum coherence, entanglement, invariants of the gauge field, or any other deep physical property of reality, non-materialist physicalism can avert the spectre of epiphenomenalism by postulating that the relevant properties of matter that make us conscious are precisely those that give our brains a computational edge (relative to what evolution was able to find in the vicinity of the fitness landscape explored in our history).
Will Pure Replicators Use Valence Gradients at All?
Whether we work under the assumption of functionalism or non-materialist physicalism, we already know that our genes found happiness and suffering to be evolutionary advantageous. So we know that there is at least a set of constraints, efficiency metrics, and input-output mappings that make both phenomenal pleasure and pain very good algorithms (functionalism) or physical implementations (non-materialist physicalism). But will the parameters necessitated by replicators in the long-term future have these properties? Remember that evolution was only able to explore a restricted state-space of possible brain implementations delimited by the pre-existing gene pool (and the behavioral requirements provided by the environment). So, in one extreme case, it may be the case that a fully optimized brain simply does not need consciousness to solve problems. And in another extreme, it may turn out that consciousness is extraordinarily more powerful when used in an optimal way. Would this be good or bad?
What’s the best case scenario? Well, the absolute best possible case is a case so optimistic and incredibly lucky that if it turned out to be true, it would probably make me believe in a benevolent God (or Simulation). This is the case where it turns out that only positive valence gradients are computationally superior to every other alternative given a set of constraints, input-output mappings, and arbitrary efficiency functions. In this case, the most powerful pure replicators, despite their lack of altruism, will nonetheless be pumping out massive amounts of systems that produce unspeakable levels of bliss. It’s as if the very nature of this universe is blissful… we simply happen to suffer because we are stuck in a tiny wrinkle at the foothills of the optimization process of evolution.
In the extreme opposite case, it turns out that only negative valence gradients offer strict computational benefits under heavy optimization. This would be Hell. Or at least, it would tend towards Hell in the long run. If this happens to be the universe we live in, let’s all agree to either conspire to prevent evolution from moving on, or figure out the way to turn it off. In the long term, we’d expect every being alive (or AI, upload, etc.) to be a zombie or a piece of dolorium. Not a fun idea.
In practice, it’s much more likely that both positive and negative valence gradients will be of some use in some contexts. Figuring out exactly which contexts these are might be both extremely important, and also extremely dangerous. In particular, finding out in advance which computational tasks make positive valence gradients a superior alternative to other methods of doing the relevant computations would inform us about the sorts of cultures, societies, religions, and technologies that we should be promoting in order to give this a push in the right direction (and hopefully out-run the environments that would make negative valence gradients adaptive).
Unless we create a Singleton early on, it’s likely that by default all future entities in the long-term future will be non-altruistic pure replicators. But it is also possible that there are multiple attractors (i.e. evolutionarily stable ecosystems) in which different computational properties of consciousness are adaptive. Thus the case for pushing our evolutionary history in the right direction right now before we give up.
Coming Next: The Hierarchy of Cooperators
Now that we covered the four worldviews, formalized what it means to be a pure replicator, and analyzed the possible future outcomes based on the computational properties of consciousness (and of valence gradients in particular), we are ready to face the game of reality in its own terms.
Team Consciousness, we need to to get our act together. We need a systematic worldview, availability of states of consciousness, set of beliefs and practices to help us prevent pure replicator takeovers.
But we cannot do this as long as we are in the dark about the sorts of entities, both consciousness-focused and pure replicators, who are likely to arise in the future in response to the selection pressures that cultural and technological change are likely to produce. In Part II of The Universal Plot we will address this and more. Stay tuned…
* Rather, they usually claim that, given that a Chinese Room is implemented with physical material from this universe and subject to the typical constraints of this world, it is extremely unlikely that a universe-sized look-up table would be producing the output. Hence, the algorithms that are producing the output are probably highly complex and using information processing with human-like linguistic representations, which means that, by all means, the Chinese Room it very likely understanding what it is outputting.
