Letter I: Introduction
We are Maggie & Anders. A mostly harmless Swedish old-timer couple only now beginning to discover the advanced incompetence that is the proto-science — or “alchemy” — of consciousness research. A few centuries ago a philosopher of chemistry could have claimed with a straight face to be quite certain that a substance with negative mass had to be invoked to explain the phenomenon of combustion. Another could have been equally convinced that the chemistry of life involves a special force of nature absent from all non-living matter. A physicist of today may recognize that the study of consciousness has even less experimental foundation than alchemy did, yet be confident that at least it cannot feel like something to be a black hole. Since, obviously, black holes are simple objects and consciousness is a phenomenon which only emerges from “complexity” as high as that of a human brain.
Is there some ultimate substrate, basic to reality and which has properties intrinsic to itself? If so, is elementary sentience one of those properties? Or is it “turtles all the way down” in a long regress where all of reality can be modeled as patterns within patterns within patterns ending in Turing-style “bits”? Or parsimoniously never ending?
Will it turn out to be patterns all the way down, or sentience all the way up? Should people who believe themselves to perhaps be in an ancestor simulation take for granted that consciousness exists for biologically-based people in base-level reality? David Chalmers does. So at least that must be one assumption it is safe to make, isn’t it? And the one about no sentience existing in a black hole. And the one about phlogiston. And the four chemical elements.
This really is good material for silly comedy or artistic satire. To view a modest attempt by us in that direction, please feel encouraged to enjoy this youtube video we made with QRI in mind:
When ignorance is near complete, it is vital to think outside the proverbial box if progress is to be made. However, spontaneous creative speculation is more context-constrained than it feels like, and it rarely correlates all that beautifully with anything useful. Any science has to work via the baby steps of testable predictions. The integrated information theory (IIT) does just that, and has produced encouraging early results. IIT could turn out to be a good starting point for eventually mapping and modeling all of experiential phenomenology. For a perspective, IIT 3.0 may be comparable to how Einstein’s modeling of the photoelectric effect stands in relation to a full-blown theory of quantum gravity. There is a fair bit of ground to cover. We have not been able to find any group more likely than the QRI to speed up the process whereby humanity eventually manages to cover that ground. That is, if they get a whole lot of help in the form of outreach, fundraising and technological development. Early pioneers have big hurdles to overcome, but the difference they can make for the future is enormous.
For those who feel inspired, a nice start is to go through all that is on or linked via the QRI website. Indulge in Principia Qualia. If that leaves you confused on a higher level, you are in good company. With us. We are halfway senile and are not information theorists, neuroscientists or physicists. All we have is a nerdy sense of humor and work experience in areas like marketing and planetary geochemistry. One thing we think we can do is help bridge the gap between “experts” and “lay people”. Instead of “explain it like I am five”, we offer the even greater challenge of explaining it like we are Maggie & Anders. Manage that, and you will definitely be wiser afterwards!

Letter II: State-Space of Matter and State-Space of Consciousness
A core aspect of science is the mapping out of distributions, spectra, and state-spaces of the building blocks of reality. Naturally occurring states of things can be spontaneously discovered. To gain more information about them, one can experimentally alter such states to produce novel ones, and then analyze them in a systematic way.
The full state-space of matter is multidimensional and vast. Zoom in anywhere in it and there will be a number of characteristic physics phenomena appearing there. Within a model of the state-space you can follow independent directions as you move towards regions and points. As an example, you can hold steady at one particular simple chemical configuration. Diamond, say. The stable region of diamond and its emergent properties like high hardness extends certain distances in other parameter directions such as temperature and pressure. The diamond region has neighboring regions with differently structured carbon, such as graphite. Diamond and graphite make for an interesting case since the property of hardness emerges very differently in the two regions. (In the pure carbon state-space the dimensions denoting amounts of all other elements can be said to be there but set to zero). Material properties like hardness can be modeled as static phenomena. According to IIT however, consciousness cannot. It’s still an emergent property of matter though, so just stay in the matter state-space and add a time dimension to it. Then open chains and closed loops of causation emerge as a sort of fundamental level of what matter “does”. Each elementary step of causation may be regarded to produce or intrinsically be some iota of proto-experience. In feedback loops this self-amplifies into states of feeling like something. Many or perhaps most forms of matter can “do” these basic things at various regions of various combinations of parameter settings. Closed causal loops require more delicate fine-tuning in parameter space, so the state-space of nonconscious causation structure is larger than that of conscious structure. The famous “hard problem” has to do with the fact that both an experientially very weak and a very strong state can emerge from the same matter (shown to be the case so far only within brains). A bit like the huge difference in mechanical hardness of diamond and graphite both emerging from the same pure carbon substrate (a word play on “hard” to make it sticky).
By the logic of IIT it should be possible to model (in arbitrarily coarse or fine detail) the state-space of all conscious experience whose substrate is all possible physical states of pure carbon. Or at room temperature in any material. And so on. If future advanced versions of IIT turn out to be a success then we may guess there’ll be a significant overlap to allow for a certain “substrate invariance” for hardware that can support intelligence with human-recognizable consciousness. Outside of that there will be a gargantuan additional novel space to explore. It ought to contain maxima of (intrinsic) attractiveness, none of which need to reside within what a biological nervous system can host. Biological evolution has only been able to search through certain parts of the state-space of matter. One thing it has not worked with on Earth is pure carbon. Diamond tooth enamel or carbon nanotube tendons would be useful but no animal has them. What about conscious states? Has biology come close to hit upon any of the optima in those? If all of human sentience is like planet Earth, and all of Terrestrial biologically-based sentience is like the whole Solar System, that leaves an entire extrasolar galaxy out there to explore. (Boarding call: Space X Flight 42 bound for Nanedi Settlement, Mars. Sentinauts please go to the Neuralink check-in terminal).
Of course we don’t currently know how IIT is going to stand up, but thankfully it does make testable predictions. There is, therefore, a beginning of something to be hoped for with it. In a hopeful scenario IIT turns out to be like special relativity, and what QRI is reaching for is like quantum gravity. It will be a process of taking baby steps, for sure. But each step is likely to bring benefits in many ways.
