Vedanta teaches that consciousness is singular, all happenings are played out in one universal consciousness and there is no multiplicity of selves.
– Erwin Schrödinger, ‘My View of the World’, 1951
Enlightenment came to me suddenly and unexpectedly one afternoon in March  when I was walking up to the school notice board to see whether my name was on the list for tomorrow’s football game. I was not on the list. And in a blinding flash of inner light I saw the answer to both my problems, the problem of war and the problem of injustice. The answer was amazingly simple. I called it Cosmic Unity. Cosmic Unity said: There is only one of us. We are all the same person. I am you and I am Winston Churchill and Hitler and Gandhi and everybody. There is no problem of injustice because your sufferings are also mine. There will be no problem of war as soon as you understand that in killing me you are only killing yourself.
– Freeman Dyson, ‘Disturbing the Universe’, 1979
Common sense assumes “closed” individualism: we are born, live awhile, and then die. Common sense is wrong about most things, and the assumption of enduring metaphysical egos is true to form. Philosophers sometimes speak of the “indiscernibility of identicals”. If a = b, then everything true of a is true of b. This basic principle of logic is trivially true. Our legal system, economy, politics, academic institutions and personal relationships assume it’s false. Violation of elementary logic is a precondition of everyday social life. It’s hard to imagine any human society that wasn’t founded on such a fiction. The myth of enduring metaphysical egos and “closed” individualism also leads to a justice system based on scapegoating. If we were accurately individuated, then such scapegoating would seem absurd.
Among the world’s major belief-systems, Buddhism comes closest to acknowledging “empty” individualism: enduring egos are a myth (cf. “non-self” or Anatta – Wikipedia). But Buddhism isn’t consistent. All our woes are supposedly the product of bad “karma”, the sum of our actions in this and previous states of existence. Karma as understood by Buddhists isn’t the deterministic cause and effect of classical physics, but rather the contribution of bad intent and bad deeds to bad rebirths.
Among secular philosophers, the best-known defender of (what we would now call) empty individualism minus the metaphysical accretions is often reckoned David Hume. Yet Hume was also a “bundle theorist”, sceptical of the diachronic and the synchronic unity of the self. At any given moment, you aren’t a unified subject (“For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat, cold, light or shade, love or hatred, pain or pleasure. I can never catch myself at any time without a perception, and can never observe anything but the perception” (‘On Personal Identity’, A Treatise of Human Nature, 1739)). So strictly, Hume wasn’t even an empty individualist. Contrast Kant’s “transcendental unity of apperception”, aka the unity of the self.
An advocate of common-sense closed individualism might object that critics are abusing language. Thus “Winston Churchill”, say, is just the name given to an extended person born in 1874 who died in 1965. But adhering to this usage would mean abandoning the concept of agency. When you raise your hand, a temporally extended entity born decades ago doesn’t raise its collective hand. Raising your hand is a specific, spatio-temporally located event. In order to make sense of agency, only a “thin” sense of personal identity can work.
According to “open” individualism, there exists only one numerically identical subject who is everyone at all times. Open individualism was christened by philosopher Daniel Kolak, author of I Am You (2004). The roots of open individualism are ancient, stretching back at least to the Upanishads. The older name is monopsychism. I am Jesus, Moses and Einstein, but also Hitler, Stalin and Genghis Khan. And I am also all pigs, dinosaurs and ants: subjects of experience date to the late Pre-Cambrian, if not earlier.
My ethical sympathies lie with open individualism; but as it stands, I don’t see how a monopsychist theory of identity can be true. Open or closed individualism might (tenuously) be defensible if we were electrons (cf. One-electron universe – Wikipedia). However, sentient beings are qualitatively and numerically different. For example, the half-life of a typical protein in the brain is an estimated 12–14 days. Identity over time is a genetically adaptive fiction for the fleetingly unified subjects of experience generated by the CNS of animals evolved under pressure of natural selection (cf. Was Parfit correct we’re not the same person that we were when we were born?). Even memory is a mode of present experience. Both open and closed individualism are false.
By contrast, the fleeting synchronic unity of the self is real, scientifically unexplained (cf. the binding problem) and genetically adaptive. How a pack of supposedly decohered membrane-bound neurons achieves a classically impossible feat of virtual world-making leads us into deepphilosophical waters. But whatever the explanation, I think empty individualism is true. Thus I share with my namesakes – the authors of The Hedonistic Imperative (1995) – the view that we ought to abolish the biology of suffering in favour of genetically-programmed gradients of superhuman bliss. Yet my namesakes elsewhere in tenselessly existing space-time (or Hilbert space) physically differ from the multiple David Pearces (DPs) responding to your question. Using numerical superscripts, e.g. DP^564356, DP^54346 (etc), might be less inappropriate than using a single name. But even “DP” here is misleading because such usage suggests an enduring carrier of identity. No such enduring carrier exists, merely modestly dynamically stable patterns of fundamental quantum fields. Primitive primate minds were not designed to “carve Nature at the joints”.
However, just because a theory is true doesn’t mean humans ought to believe in it. What matters are its ethical consequences. Will the world be a better or worse place if most of us are closed, empty or open individualists? Psychologically, empty individualism is probably the least emotionally satisfying account of personal identity – convenient when informing an importunate debt-collection company they are confusing you with someone else, but otherwise a recipe for fecklessness, irresponsibility and overly-demanding feats of altruism. Humans would be more civilised if most people believed in open individualism. The factory-farmed pig destined to be turned into a bacon sandwich is really you: the conventional distinction between selfishness and altruism collapses. Selfish behaviour is actually self-harming. Not just moral decency, but decision-theoretic rationality dictates choosing a veggie burger rather than a meat burger. Contrast the metaphysical closed individualism assumed by, say, the Less Wrong Decision Theory FAQ. And indeed, all first-person facts, not least the distress of a horribly abused pig, are equally real. None are ontologically privileged. More speculatively, if non-materialist physicalism is true, then fields of subjectivity are what the mathematical formalism of quantum field theory describes. The intrinsic nature argument proposes that only experience is physically real. On this story, the mathematical machinery of modern physics is transposed to an idealist ontology. This conjecture is hard to swallow; I’m agnostic.
Speculative solutions to the Hard Problem of consciousness aside, the egocentric delusion of Darwinian life is too strong for most people to embrace open individualism with conviction. Closed individualism is massively fitness-enhancing (cf. Are you the center of the universe?). Moreover, temperamentally happy people tend to have a strong sense of enduring personal identity and agency; depressives have a weaker sense of personhood. Most of the worthwhile things in this world (as well as its biggest horrors) are accomplished by narcissistic closed individualists with towering egos. Consider the transhumanist agenda. Working on a cure for the terrible disorder we know as aging might in theory be undertaken by empty individualists or open individualists; but in practice, the impetus for defeating death and aging comes from strong-minded and “selfish” closed individualists who don’t want their enduring metaphysical egos to perish. Likewise, the well-being of all sentience in our forward light-cone – the primary focus of most DPs – will probably be delivered by closed individualists. Benevolent egomaniacs will most likely save the world.
“One for all, all for one”, as Alexandre Dumas put it in The Three Musketeers?
Maybe one day: full-spectrum superintelligence won’t have a false theory of personal identity. “Unus pro omnibus, omnes pro uno” is the unofficial motto of Switzerland. It deserves to be the ethos of the universe.
Compared to the natural sciences (cf. the Standard Model in physics) or computing (cf. the Universal Turing Machine), the “science” of consciousness is pre-Galilean, perhaps even pre-Socratic. State-enforced censorship of the range of subjective properties of matter and energy in the guise of a prohibition on psychoactive experimentation is a powerful barrier to knowledge. The legal taboo on the empirical method in consciousness studies prevents experimental investigation of even the crude dimensions of the Hard Problem, let alone locating a solution-space where answers to our ignorance might conceivably be found.
Singularity theorists are undaunted by our ignorance of this fundamental feature of the natural world. Instead, the Singularitarians offer a narrative of runaway machine intelligence in which consciousness plays a supporting role ranging from the minimal and incidental to the completely non-existent. However, highlighting the Singularity movement’s background assumptions about the nature of mind and intelligence, not least the insignificance of the binding problem to AGI, reveals why FUSION and REPLACEMENT scenarios are unlikely – though a measure of “cyborgification” of sentient biological robots augmented with ultrasmart software seems plausible and perhaps inevitable.
If full-spectrum superintelligence does indeed entail navigation and mastery of the manifold state-spaces of consciousness, and ultimately a seamless integration of this knowledge with the structural understanding of the world yielded by the formal sciences, then where does this elusive synthesis leave the prospects of posthuman superintelligence? Will the global proscription of radically altered states last indefinitely?
Social prophecy is always a minefield. However, there is one solution to the indisputable psychological health risks posed to human minds by empirical research into the outlandish state-spaces of consciousness unlocked by ingesting the tryptamines, phenylethylamines, isoquinolines and other pharmacological tools of sentience investigation. This solution is to make “bad trips” physiologically impossible – whether for individual investigators or, in theory, for human society as a whole. Critics of mood-enrichment technologies sometimes contend that a world animated by information-sensitive gradients of bliss would be an intellectually stagnant society: crudely, a Brave New World. On the contrary, biotech-driven mastery of our reward circuitry promises a knowledge explosion in virtue of allowing a social, scientific and legal revolution: safe, full-spectrum biological superintelligence. For genetic recalibration of hedonic set-points – as distinct from creating uniform bliss – potentially leaves cognitive function and critical insight both sharp and intact; and offers a launchpad for consciousness research in mind-spaces alien to the drug-naive imagination. A future biology of invincible well-being would not merely immeasurably improve our subjective quality of life: empirically, pleasure is the engine of value-creation. In addition to enriching all our lives, radical mood-enrichment would permit safe, systematic and responsible scientific exploration of previously inaccessible state-spaces of consciousness. If we were blessed with a biology of invincible well-being, exotic state-spaces would all be saturated with a rich hedonic tone.
Until this hypothetical world-defining transition, pursuit of the rigorous first-person methodology and rational drug-design strategy pioneered by Alexander Shulgin in PiHKAL and TiHKAL remains confined to the scientific counterculture. Investigation is risky, mostly unlawful, and unsystematic. In mainstream society, academia and peer-reviewed scholarly journals alike, ordinary waking consciousness is assumed to define the gold standard in which knowledge-claims are expressed and appraised. Yet to borrow a homely-sounding quote from Einstein, “What does the fish know of the sea in which it swims?” Just as a dreamer can gain only limited insight into the nature of dreaming consciousness from within a dream, likewise the nature of “ordinary waking consciousness” can only be glimpsed from within its confines. In order to scientifically understand the realm of the subjective, we’ll need to gain access to all its manifestations, not just the impoverished subset of states of consciousness that tended to promote the inclusive fitness of human genes on the African savannah.
Why the Proportionality Thesis Implies an Organic Singularity
So if the preconditions for full-spectrum superintelligence, i.e. access to superhuman state-spaces of sentience, remain unlawful, where does this roadblock leave the prospects of runaway self-improvement to superintelligence? Could recursive genetic self-editing of our source code repair the gap? Or will traditional human personal genomes be policed by a dystopian Gene Enforcement Agency in a manner analogous to the coercive policing of traditional human minds by the Drug Enforcement Agency?
Even in an ideal regulatory regime, the process of genetic and/or pharmacological self-enhancement is intuitively too slow for a biological Intelligence Explosion to be a live option, especially when set against the exponential increase in digital computer processing power and inorganic AI touted by Singularitarians. Prophets of imminent human demise in the face of machine intelligence argue that there can’t be a Moore’s law for organic robots. Even the Flynn Effect, the three-points-per-decade increase in IQ scores recorded during the 20th century, is comparatively puny; and in any case, this narrowly-defined intelligence gain may now have halted in well-nourished Western populations.
However, writing off all scenarios of recursive human self-enhancement would be premature. Presumably, the smarter our nonbiological AI, the more readily AI-assisted humans will be able recursively to improve our own minds with user-friendly wetware-editing tools – not just editing our raw genetic source code, but also the multiple layers of transcription and feedback mechanisms woven into biological minds. Presumably, our ever-smarter minds will be able to devise progressively more sophisticated, and also progressively more user-friendly, wetware-editing tools. These wetware-editing tools can accelerate our own recursive self-improvement – and manage potential threats from nonfriendly AGI that might harm rather than help us, assuming that our earlier strictures against the possibility of digital software-based unitary minds were mistaken. MIRI rightly call attention to how small enhancements can yield immense cognitive dividends: the relatively short genetic distance between humans and chimpanzees suggests how relatively small enhancements can exert momentous effects on a mind’s general intelligence, thereby implying that AGIs might likewise become disproportionately powerful through a small number of tweaks and improvements. In the post-genomic era, presumably exactly the same holds true for AI-assisted humans and transhumans editing their own minds. What David Chalmers calls the proportionality thesis, i.e. increases in intelligence lead to proportionate increases in the capacity to design intelligent systems, will be vindicated as recursively self-improving organic robots modify their own source code and bootstrap our way to full-spectrum superintelligence: in essence, an organic Singularity. And in contrast to classical digital zombies, superficially small molecular differences in biological minds can result in profoundly different state-spaces of sentience. Compare the ostensibly trivial difference in gene expression profiles of neurons mediating phenomenal sight and phenomenal sound – and the radically different visual and auditory worlds they yield.
Compared to FUSION or REPLACEMENT scenarios, the AI-human CO-EVOLUTION conjecture is apt to sound tame. The likelihood our posthuman successors will also be our biological descendants suggests at most a radical conservativism. In reality, a post-Singularity future where today’s classical digital zombies were superseded merely by faster, more versatile classical digital zombies would be infinitely duller than a future of full-spectrum supersentience. For all insentient information processors are exactly the same inasmuch as the living dead are not subjects of experience. They’ll never even know what it’s like to be “all dark inside” – or the computational power of phenomenal object-binding that yields illumination. By contrast, posthuman superintelligence will not just be quantitatively greater but also qualitatively alien to archaic Darwinian minds. Cybernetically enhanced and genetically rewritten biological minds can abolish suffering throughout the living world and banish experience below “hedonic zero” in our forward light-cone, an ethical watershed without precedent. Post-Darwinian life can enjoy gradients of lifelong blissful supersentience with the intensity of a supernova compared to a glow-worm. A zombie, on the other hand, is just a zombie – even if it squawks like Einstein. Posthuman organic minds will dwell in state-spaces of experience for which archaic humans and classical digital computers alike have no language, no concepts, and no words to describe our ignorance. Most radically, hyperintelligent organic minds will explore state-spaces of consciousness that do not currently play any information-signalling role in living organisms, and are impenetrable to investigation by digital zombies. In short, biological intelligence is on the brink of a recursively self-amplifying Qualia Explosion – a phenomenon of which digital zombies are invincibly ignorant, and invincibly ignorant of their own ignorance. Humans too of course are mostly ignorant of what we’re lacking: the nature, scope and intensity of such posthuman superqualia are beyond the bounds of archaic human experience. Even so, enrichment of our reward pathways can ensure that full-spectrum biological superintelligence will be sublime.
Life could be wonderful. Genetically phasing out suffering in favour of hardwired happiness ought to be mainstream. Today, it’s a fringe view. It’s worth asking why.
Perhaps the first scientifically-literate blueprint for a world without suffering was written by Lewis Mancini. “Brain stimulation and the genetic engineering of a world without pain” was published in the journal Medical Hypotheses in 1990. As far as I can tell, the paper sunk almost without a trace. Ignorant of Mancini’s work, I wrote The Hedonistic Imperative (HI) in 1995. I’ve plugged away at the theme ever since. Currently, a small, scattered minority of researchers believe that replacing the biology of suffering with gradients of genetically preprogrammed well-being is not just ethical but obviously so.
Alas, perceptions of obviousness vary. Technically, at least, the abolitionist project can no longer easily be dismissed as science fiction. The twenty-first century has already witnessed the decoding of the human genome, the development and imminent commercialisation of in vitro meat, the dawn of CRISPR genome-editing and the promise of synthetic gene drives. Identification of alleles and allelic combinations governing everything from pain-sensitivity to hedonic range and hedonic set-points is complementing traditional twin studies. The high genetic loading of subjective well-being and mental ill-health is being deciphered. The purely technical arguments against the genetic feasibility of creating a happy living world are shrinking. But genetic status quo bias is deeply entrenched. The sociopolitical obstacles to reprogramming the biosphere are daunting.
1) Timescales. Lewis Mancini reckons that completion of the abolitionist project will take thousands of years. HI predicts that the world’s last unpleasant experience will occur a few centuries hence, perhaps in some obscure marine invertebrate. If, fancifully, consensus existed for a global species-project, then 100 – 150 years (?) might be a credible forecast. Alas, such a timescale is wildly unrealistic. No such consensus exists or is plausibly in prospect. For sure, ask people a question framed on the lines of “Do you agree with Gautama Buddha, ‘May all that have life be delivered from suffering’?” and assent might be quite high. Some kind of quantified, cross-cultural study of radical Buddhist or Benthamite abolitionism would be interesting. Yet most people balk at what the scientific implementation of such a vision practically entails – if they reflect on abolitionist bioethics at all. “That’s justBrave New World” is a common response among educated Westerners to the idea of engineering “unnatural” well-being. Typically, EAs are focused on measurable results in foreseeable timeframes in areas where consensus is broad and deep, for instance the elimination of vector-borne disease. Almost everyone agrees that eliminating malaria will make the world a better place. Malaria can be eradicated this century.
2)TheHedonic Treadmill. In recent decades, popular awareness of the hedonic treadmill has grown. Sadly, most nonbiological interventions to improve well-being may not have the dramatic long-term impact we naïvely hope. However, awareness of the genetic underpinnings of the hedonic treadmill is sketchy. Knowledge of specific interventions we can plan to subvert its negative feedback mechanisms is sketchier still. Compared to more gross and visible ills, talk of “low hedonic set-points” (etc) is nebulous. Be honest, which would you personally choose if offered: a vast national lottery win (cf. How Winning The Lottery Affects Happiness) or a modestly higher hedonic set-point? Likewise, the prospect of making everyone on Earth prosperous sounds more effectively altruistic (cf. Can “effective altruism” maximise the bang for each charitable buck?) than raising their hedonic defaults – even if push-button hedonic uplift were now feasible, which it isn’t, or at least not without socially unacceptable consequences.
3)The Spectre of Eugenics. Any confusion between the racial hygiene policies of the Third Reich and the project of genetically phasing out suffering in all sentient beings ought to be laughable. Nonetheless, many people recoil at the prospect of “designer babies”. Sooner or later, the ”e”-word crops up in discussions of genetic remediation and enhancement. If we assume that bioconservative attitudes to baby-making will prevail worldwide indefinitely, and the reproductive revolution extends at best only to a minority of prospective parents, then the abolitionist project will never happen. What we call the Cambrian Explosion might alternatively be classified as the Suffering Explosion. If we don’t tackle the biological-genetic roots of suffering at source – “eugenics”, if you will – then pain and suffering will proliferate until Doomsday. Without eugenics, the world’s last unpleasant experience may occur millions or even billions of years hence.
5) Organisation and Leadership. Both secular and religious organizations exist whose tenets include the outright abolition of suffering. EAs can and do join such groups. However, sadly, I don’t know of a single organisation dedicated to biological-genetic solutions to the problem of suffering. Among transhumanists, for instance, radical life-extension and the prospect of posthuman superintelligence loom larger than biohappiness – though article 7 of the Transhumanist Declaration is admirably forthright: a commitment to the well-being of all sentience. Also, I think we need star power: the blessing of some charismatic billionaire or larger-than-life media celebrity. “Bill Gates says let’s use biotechnology to phase out the genetic basis of suffering” would be a breakthrough. Or even Justin Bieber.
For my part, I’m just a writer/researcher. We have our place! My guess is that this century will see more blueprints and manifestos and grandiose philosophical proposals together with concrete, incremental progress from real scientists. The genetic basis of suffering will eventuallybe eradicated across the tree of life, not in the name of anything “hedonistic” or gradients of intelligent bliss, and certainly not in the name of negative utilitarianism, but perhaps under the label of the World Health Organisation’s definition of health (cf. Constitution of WHO: principles). Taken literally, the constitution of the WHO enshrines the most daringly ambitious vision of the future of sentience ever conceived. Lifelong good health (“complete physical, mental and social well-being”) for all sentient beings is a noble aspiration. Regardless of race or species, all of us deserve good health as so defined. A biology of information-sensitive gradients of physical, mental and social well-being (HI) is more modest and workable thanks to biotech. Optimistically, life on Earth has only a few more centuries of misery and malaise to go.
The appearance of arbitrary contingency to our diverse qualia – and undiscovered state-spaces of posthuman qualia and hypothetical micro-qualia – may be illusory. Perhaps they take the phenomenal values they do as a matter of logico-mathematical necessity. I’d make this conjecture against the backdrop of some kind of zero ontology. Intuitively, there seems no reason for anything at all to exist. The fact that the multiverse exists (apparently) confounds one’s pre-reflective intuitions in the most dramatic possible way. However, this response is too quick. The cosmic cancellation of the conserved constants (mass-energy, charge, angular momentum) to zero, and the formal equivalence of zero information to all possible descriptions [the multiverse?] means we have to take seriously this kind of explanation-space. The most recent contribution to the zero-ontology genre is physicist Lawrence Krauss’s readable but frustrating “A Universe from Nothing: Why There Is Something Rather Than Nothing“. Anyhow, how does a zero ontology tie in with (micro-)qualia? Well, if the solutions to the master equation of physics do encode the field-theoretic values of micro-qualia, then perhaps their numerically encoded textures “cancel out” to zero too. To use a trippy, suspiciously New-Agey-sounding metaphor, imagine the colours of the rainbow displayed as a glorious spectrum – but on recombination cancelling out to no colour at all. Anyhow, I wouldn’t take any of this too seriously: just speculation on idle speculation. It’s tempting simply to declare the issue of our myriad qualia to be an unfathomable mystery. And perhaps it is. But mysterianism is sterile.
In response to the Quora question “I feel like a lot of evil actions in the world have supporters who justify them (like Nazis). Can you come up with some convincing ways in which some of the most evil actions in the world could be justified?” David Pearce writes:
“Tout comprendre, c’est tout pardonner.”
(Leo Tolstoy, War and Peace)
“Despite everything, I believe that people are really good at heart.”
The risk of devising justifications of the worst forms of human behaviour is there are people gullible enough to believe them. It’s not as though anti-Semitism died with the Third Reich. Even offering dispassionate causal explanation can sometimes be harmful. So devil’s advocacy is an intellectual exercise to be used sparingly.
That said, the historical record suggests that human societies don’t collectively set out to do evil. Rather, primitive human emotions get entangled with factually mistaken beliefs and ill-conceived metaphysics with ethically catastrophic consequences. Thus the Nazis seriously believed in the existence of an international Jewish conspiracy against the noble Aryan race. Hitler, so shrewd in many respects, credulously swallowed The Protocols of the Elders of Zion. And as his last testamentdisclosed, obliquely, Hitler believed that the gas chambers were a “more humane means” than the terrible fate befalling the German Volk. Many Nazis (Himmler, Höss, Stangl, and maybe even Eichmann) believed that they were acting from a sense of duty – a great burden stoically borne. And such lessons can be generalised across history. If you believed, like the Inquisition, that torturing heretics was the only way to save their souls from eternal damnation in Hell, would you have the moral courage to do likewise? If you believed that the world would be destroyed by the gods unless you practised mass human sacrifice, would you participate? [No, in my case, albeit for unorthodox reasons.]
In a secular context today, there exist upstanding citizens who would like future civilisation to run “ancestor simulations”. Ancestor simulations would create inconceivably more suffering than any crime perpetrated by the worst sadist or deluded ideologue in history – at least if the computational-functional theory of consciousness assumed by their proponents is correct. If I were to pitch a message to life-lovers aimed at justifying such a monstrous project, as you request, then I guess I’d spin some yarn about how marvellous it would be to recreate past wonders and see grandpa again.
And so forth.
What about the actions of individuals, as distinct from whole societies? Not all depraved human behaviour stems from false metaphysics or confused ideology. The grosser forms of human unpleasantness often stem just from our unreflectively acting out baser appetites (cf. Hamiltonian spite). Consider the neuroscience of perception. Sentient beings don’t collectively perceive a shared public world. Each of us runs an egocentric world-simulation populated by zombies (sic). We each inhabit warped virtual worlds centered on a different body-image, situated within a vastreality whose existence can be theoretically inferred. Or so science says. Most people are still perceptual naïve realists. They aren’t metaphysicians, or moral philosophers, or students of the neuroscience of perception. Understandably, most people trust the evidence of their own eyes and the wisdom of their innermost feelings, over abstract theory. What “feels right” is shaped by natural selection. And what “feels right” within one’s egocentric virtual world is often callous and sometimes atrocious. Natural selection is amoral. We are all slavesto the pleasure-pain axis, however heavy the layers of disguise. Thanks to evolution, our emotions are “encephalised” in grotesque ways. Even the most ghastly behaviour can be made to seem natural –like Darwinian life itself.
Are there some forms of human behaviour so appalling that I’d find it hard to play devil’s advocate in their mitigation – even as an intellectual exercise?
Well, perhaps consider, say, the most reviled hate-figures in our society – even more reviled than murderers or terrorists. Most sexually active paedophiles don’t set out to harm children: quite the opposite, harm is typically just the tragic by-product of a sexual orientation they didn’t choose. Posthumansmay reckon that all Darwinian relationships are toxic. Of course, not all monstrous human behavior stems from wellsprings as deep as sexual orientation. Thus humans aren’t obligate carnivores. Most (though not all) contemporary meat eaters, if pressed, will acknowledge in the abstract that a pig is as sentient and sapient as a prelinguistic human toddler. And no contemporary meat eaters seriously believe that their victims have committed a crime (cf. Animal trial – Wikipedia). Yet if questioned why they cause such terrible suffering to the innocent, and why they pay for a hamburger rather than a veggieburger, a meat eater will come up with perhaps the lamest justification for human depravity ever invented:
“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.

5) Transhuman psychedelia / novel state spaces of consciousness.
Analogues of cognition, volition and emotion as conceived by humans have been selectively retained, though with a richer phenomenology than our thin logico-linguistic thought. Other fundamental categories of mind have been discovered via genetic tinkering and pharmacological experiment. Such novel faculties are intelligently harnessed in the transhuman CNS. However, the ordinary waking consciousness of Darwinian life has been replaced by state-spaces of mind physiologically inconceivable to Homo sapiens. Gene-editing tools have opened up modes of consciousness that make the weirdest human DMT trip akin to watching paint dry. These disparate states-spaces of consciousness do share one property: they are generically blissful. “Bad trips” as undergone by human psychonauts are physically impossible because in the year 3000 the molecular signature of experience below “hedonic zero” is missing.

The intensity of everyday experience surpasses today’s human imagination. Size doesn’t matter to digital data-processing, but bigger brains with reprogrammed, net-enabled neurons and richer synaptic connectivity can exceed the maximum sentience of small, simple, solipsistic mind-brains shackled by the constraints of the human birth-canal. The theoretical upper limits to phenomenally bound mega-minds, and the ultimate intensity of experience, remain unclear. Intuitively, humans have a dimmer-switch model of consciousness – with e.g. ants and worms subsisting with minimal consciousness and humans at the pinnacle of the Great Chain of Being. Yet Darwinian humans may resemble sleepwalkers compared to our fourth-millennium successors. Today we say we’re “awake”, but mankind doesn’t understand what “posthuman intensity of experience” really means. What earthly animal comes closest to human levels of sentience?
7) Reversible mind-melding.
Early in the twenty-first century, perhaps the only people who know what it’s like even partially to share a mind are the conjoined Hogan sisters. Tatiana and Krista Hogan share a thalamic bridge. Even mirror-touch synaesthetes can’t literally experience the pains and pleasures of other sentient beings. But in the year 3000, cross-species mind-melding technologies – for instance, sophisticated analogues of reversible thalamic bridges – and digital analogs of telepathy have led to a revolution in both ethics and decision-theoretic rationality.

8) The Anti-Speciesist Revolution / worldwide veganism/invitrotarianism.
Sentient beings help rather than harm each other. The successors of today’s primitive CRISPR genome-editing and synthetic gene drive technologies have reworked the global ecosystem. Darwinian life was nasty, brutish and short. Extreme violence and useless suffering were endemic. In the year 3000, fertility regulation via cross-species immunocontraception has replaced predation, starvation and disease to regulate ecologically sustainable population sizes in utopian “wildlife parks”. The free-living descendants of “charismatic mega-fauna” graze happily with neo-dinosaurs, self-replicating nanobots, and newly minted exotica in surreal garden of edens. Every cubic metre of the biosphere is accessible to benign supervision – “nanny AI” for humble minds who haven’t been neurochipped for superintelligence. Other idyllic biospheres in the Solar System have been programmed from scratch. CRISPR – Wikipedia Genetically designing a happy biosphere Our Biotech Future
10) The formalism of the TOE is known. (details omitted: does Quora support LaTeX?)
[Which theory is most promising? As with the TOE, you’ll forgive me for skipping the details. In any case, my ideas are probably too idiosyncratic to be of wider interest, but for anyone curious: What is the Quantum Mind?]
12) The Meaning of Life resolved.
Everyday life is charged with a profound sense of meaning and significance. Everyone feels valuable and valued. Contrast the way twenty-first century depressives typically found life empty, absurd or meaningless; and how even “healthy” normals were sometimes racked by existential angst. Or conversely, compare how people with bipolar disorder experienced megalomania and messianic delusions when uncontrollably manic. Hyperthymic civilization in the year 3000 records no such pathologies of mind or deficits in meaning. Genetically preprogrammed gradients of invincible bliss ensure that all sentient beings find life self-intimatingly valuable. Transhumans love themselves, love life, and love each other. https://www.transhumanism.com/
13) Beautiful new emotions.
Nasty human emotions have been retired – with or without the recruitment of functional analogs to play their former computational role. Novel emotions have been biologically synthesised and their “raw feels” encephalised and integrated into the CNS. All emotion is beautiful. The pleasure axis has replaced the pleasure-pain axis as the engine of civilised life. An information-theoretic perspective on life in Heaven
14) Effectively unlimited material abundance / molecular nanotechnology.
Status goods long persisted in basement reality, as did relics of the cash nexus on the blockchain. Yet in a world where both computational resources and the substrates of pure bliss aren’t rationed, such ugly evolutionary hangovers first withered, then died. http://metamodern.com/about-the-author/ Blockchain – Wikipedia
15) Posthuman aesthetics / superhuman beauty.
The molecular signatures of aesthetic experience have been identified, purified and overexpressed. Life is saturated with superhuman beauty. What passed for “Great Art” in the Darwinian era is no more impressive than year 2000 humans might judge, say, a child’s painting by numbers or Paleolithic daubings and early caveporn. Nonetheless, critical discernment is retained. Transhumans are blissful but not “blissed out” – or not all of them at any rate. Art – Wikipedia http://www.sciencemag.org/news/2009/05/earliest-pornography
16) Gender transformation.
Like gills or a tail, “gender” in the human sense is a thing of the past. We might call some transhuman minds hyper-masculine (the “ultrahigh AQ” hyper-systematisers), others hyperfeminine (“ultralow AQ” hyper-empathisers), but transhuman cognitive styles transcend such crude dichotomies, and can be shifted almost at will via embedded AI. Many transhumans are asexual, others pan-sexual, a few hypersexual, others just sexually inquisitive. “The degree and kind of a man’s sexuality reach up into the ultimate pinnacle of his spirit”, said Nietzsche – which leads to (17).
In 3000, everyone feels physically and psychologically “better than well”. Darwinian pathologies of the flesh such as fatigue, the “leaden paralysis” of chronic depressives, and bodily malaise of any kind are inconceivable. The (comparatively) benign “low pain” alleles of the SCN9A gene that replaced their nastier ancestral cousins have been superseded by AI-based nociception with optional manual overrides. Multi-sensory bodily “superpowers” are the norm. Everyone loves their body-images in virtual and basement reality alike. Morphological freedom is effectively unbounded. Awesome robolovers, nights of superhuman sensual passion, 48-hour whole-body orgasms, and sexual practices that might raise eyebrows among prudish Darwinians have multiplied. Yet life isn’t a perpetual orgy. Academic subcultures pursue analogues of Mill’s “higher pleasures”. Paradise engineering has become a rigorous discipline. That said, a lot of transhumans are hedonists who essentially want to have superhuman fun. And why not? https://www.wired.com/2017/04/the-cure-for-pain/ http://io9.gizmodo.com/5946914/should-we-eliminate-the-human-ability-to-feel-pain http://www.bbc.com/future/story/20140321-orgasms-at-the-push-of-a-button
18) World government.
Routine policy decisions in basement reality have been offloaded to ultra-intelligent zombie AI. The quasi-psychopathic relationships of Darwinian life – not least the zero-sum primate status-games of the African savannah – are ancient history. Some conflict-resolution procedures previously off-loaded to AI have been superseded by diplomatic “mind-melds”. In the words of Henry Wadsworth Longfellow, “If we could read the secret history of our enemies, we should find in each man’s life sorrow and suffering enough to disarm all hostility.” Our descendants have windows into each other’s souls, so to speak.
19) Historical amnesia.
The world’s last experience below “hedonic zero” marked a major evolutionary transition in the evolutionary development of life. In 3000, the nature of sub-zero states below Sidgwick’s “natural watershed” isn’t understood except by analogy: some kind of phase transition in consciousness below life’s lowest hedonic floor – a hedonic floor that is being genetically ratcheted upwards as life becomes ever more wonderful. Transhumans are hyper-empathetic. They get off on each other’s joys. Yet paradoxically, transhuman mental superhealth depends on biological immunity to true comprehension of the nasty stuff elsewhere in the universal wavefunction that even mature superintelligence is impotent to change. Maybe the nature of e.g. Darwinian life, and the minds of malaise-ridden primitives in inaccessible Everett branches, doesn’t seem any more interesting than we find books on the Dark Ages. Negative utilitarianism, if it were conceivable, might be viewed as a depressive psychosis. “Life is suffering”, said Gautama Buddha, but fourth millennials feel in the roots of their being that Life is bliss.
Invincible ignorance? Perhaps. Negative Utilitarianism – Wikipedia
21) The Reproductive Revolution. Reproduction is uncommon in a post-aging society. Most transhumans originate as extra-uterine “designer babies”. The reckless genetic experimentation of sexual reproduction had long seemed irresponsible. Old habits still died hard. By year 3000, the genetic crapshoot of Darwinian life has finally been replaced by precision-engineered sentience. Early critics of “eugenics” and a “Brave New World” have discovered by experience that a “triple S” civilisation of superhappiness, superlongevity and superintelligence isn’t as bad as they supposed. https://www.reproductive-revolution.com/ https://www.huxley.net/
22) Globish (“English Plus”).
Automated real-time translation has been superseded by a common tongue – Globish – spoken, written or “telepathically” communicated. Partial translation manuals for mutually alien state-spaces of consciousness exist, but – as twentieth century Kuhnians would have put it – such state-spaces tend to be incommensurable and their concepts state-specific. Compare how poorly lucid dreamers can communicate with “awake” humans. Many Darwinian terms and concepts are effectively obsolete. In their place, active transhumanist vocabularies of millions of words are common. “Basic Globish” is used for communication with humble minds, i.e. human and nonhuman animals who haven’t been fully uplifted. Incommensurability – SEoP Uplift (science_fiction) – Wikipedia
23) Plans for Galactic colonization.
Terraforming and 3D-bioprinting of post-Darwinian life on nearby solar systems is proceeding apace. Vacant ecological niches tend to get filled. In earlier centuries, a synthesis of cryonics, crude reward pathway enhancements and immersive VR software, combined with revolutionary breakthroughs in rocket propulsion, led to the launch of primitive manned starships. Several are still starbound. Some transhuman utilitarian ethicists and policy-makers favour creating a utilitronium shockwave beyond the pale of civilisation to convert matter and energy into pure pleasure. Year 3000 bioconservatives focus on promoting life animated by gradients of superintelligent bliss. Yet no one objects to pure “hedonium” replacing unprogrammed matter.

24) The momentous “unknown unknown”.
If you read a text and the author’s last words are “and then I woke up”, everything you’ve read must be interpreted in a new light – semantic holism with a vengeance. By the year 3000, some earth-shattering revelation may have changed everything – some fundamental background assumption of earlier centuries has been overturned that might not have been explicitly represented in our conceptual scheme. If it exists, then I’ve no inkling what this “unknown unknown” might be, unless it lies hidden in the untapped subjective properties of matter and energy. Christian readers might interject “The Second Coming”. Learning the Simulation Hypothesis were true would be a secular example of such a revelation. Some believers in an AI “Intelligence Explosion” speak delphically of “The Singularity”. Whatever – Shakespeare made the point more poetically, “There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy”.
As it stands, yes, (24) is almost vacuous. Yet compare how the philosophers of classical antiquity who came closest to recognising their predicament weren’t intellectual titans like Plato or Aristotle, but instead the radical sceptics. The sceptics guessed they were ignorant in ways that transcended the capacity of their conceptual scheme to articulate. By the lights of the fourth millennium, what I’m writing, and what you’re reading, may be stultified by something that humans don’t know and can’t express. Ancient Skepticism – SEoP
OK, twenty-four predictions! Successful prophets tend to locate salvation or doom within the credible lifetime of their intended audience. The questioner asks about life in the year 3000 rather than, say, a Kurzweilian 2045. In my view, everyone reading this text will grow old and die before the predictions of this answer are realised or confounded – with one possible complication.
Opt-out cryonics and opt-in cryothanasia are feasible long before the conquest of aging. Visiting grandpa in the cryonics facility can turn death into an event in life. I’m not convinced that posthuman superintelligence will reckon that Darwinian malware should be revived in any shape or form. Yet if you want to wake up one morning in posthuman paradise – and I do see the appeal – then options exist: http://www.alcor.org/
