Thanks Matthew! I agree issues of epistemology and metaphysics get very sticky very quickly when speaking of consciousness.
My basic approach is ‘never argue metaphysics when you can argue physics’—the core strategy we have for ‘proving’ we can mathematically model qualia is to make better and more elegant predictions using our frameworks, with predicting pain/pleasure from fMRI data as the pilot project.
One way to frame this is that at various points in time, it was completely reasonable to be a skeptic about modeling things like lightning, static, magnetic lodestones, and such, mathematically. This is true to an extent even after Faraday and Maxwell formalized things. But over time, with more and more unusual predictions and fantastic inventions built around electromagnetic theory, it became less reasonable to be skeptical of such.
My metaphysical arguments are in my ‘Against Functionalism’ piece, and to date I don’t believe any commenters have addressed my core claims:
But, I think metaphysical arguments change distressingly few peoples’ minds. Experiments and especially technology changes peoples’ minds. So that’s what our limited optimization energy is pointed at right now.

Agreed :).
My basic approach is ‘never argue metaphysics when you can argue physics’
My main claim was that by only arguing physics, I will never agree upon your theory because your theory assumes the existence of elementary stuff that I don’t believe in. Therefore, I don’t understand how this really helps.
Would you be prepared say the same about many worlds vs consciousness causes collapse theories? (Let’s assume that we have no experimental data which distinguishes the two theories).

The problem with the analogy to magnetism and electricity is that fails to match the pattern of my argument. In order to incorporate magnetism into our mathematical theory of physics, we merely added more mathematical parts. In this, I see a fundamental difference between the approach you take and the approach taken by physicists when they admit the existence of new forces, or particles.
In particular, your theory of consciousness does not just do the equivalent of add a new force, or mathematical law that governs matter, or re-orient the geometry of the universe. It also posits that there is a dualism in physical stuff: that is, that matter can be identified as having both mathematical and mental properties.
Even if your theory did result in new predictions, I fail to see why I can’t just leave out the mental interpretation of it, and keep the mathematical bits for myself.
To put it another way, if you are saying that symmetry can be shown to be the same as valence, then I feel I can always provide an alternative explanation that leaves out valence as a first-class object in our ontology. If you are merely saying that symmetry is definitionally equivalent to valence, then your theory is vacuous because I can just delete that interpretation from my mathematical theory and emerge with equivalent predictions about the world.
And in practice, I would probably do so, because symmetry is not the kind of thing I think about when I worry about suffering.
I think metaphysical arguments change distressingly few peoples’ minds. Experiments and especially technology changes peoples’ minds. So that’s what our limited optimization energy is pointed at right now.
I agree that if you had made predictions that classical neuroscientists all agreed would never occur, and then proved them all wrong, then that would be striking evidence that I had made an error somewhere in my argument. But as it stands, I’m not convinced by your analogy to magnetism, or your strict approach towards talking about predictions rather than metaphysics.
(I may one day reply to your critique of FRI, as I see it as similarly flawed. But it is simply too long to get into right now.)
I think we actually mostly agree: QRI doesn’t ‘need’ you to believe qualia are real, that symmetry in some formalism of qualia corresponds to pleasure, that there is any formalism about qualia to be found at all. If we find some cool predictions, you can strip out any mention of qualia from them, and use them within the functionalism frame. As you say, the existence of some cool predictions won’t force you to update your metaphysics (your understanding of which things are ontologically ‘first class objects’).
But- you won’t be able to copy our generator by doing that, the thing that created those novel predictions, and I think that’s significant, and gets into questions of elegance metrics and philosophy of science.
I actually think the electromagnetism analogy is a good one: skepticism is always defensible, and in 1600, 1700, 1800, 1862, and 2018, people could be skeptical of whether there’s ‘deep unifying structure’ behind these things we call static, lightning, magnetism, shocks, and so on. But it was much more reasonable to be skeptical in 1600 than in 1862 (the year Maxwell’s Equations were published), and more reasonable in 1862 than it was in 2018 (the era of the iPhone).
Whether there is ‘deep structure’ in qualia is of course an open question in 2019. I might suggest STV is equivalent to a very early draft of Maxwell’s Equations: not a full systematization of qualia, but something that can be tested and built on in order to get there. And one that potentially ties together many disparate observations into a unified frame, and offers novel / falsifiable predictions (which seem incredibly worth trying to falsify!)
I’d definitely push back on the frame of dualism, although this might be a terminology nitpick: my preferred frame here is monism: https://opentheory.net/2019/06/taking-monism-seriously/ - and perhaps this somewhat addresses your objection that ‘QRI posits the existence of too many things’.
But- you won’t be able to copy our generator by doing that, the thing that created those novel predictions
I would think this might be our crux (other than perhaps the existence of qualia themselves). I imagine any predictions you produce can be adequately captured in a mathematical framework that makes no reference to qualia as ontologically primitive. And if I had such a framework, then I would have access to the generator, full stop. Adding qualia doesn’t make the generator any better—it just adds unnecessary mental stuff that isn’t actually doing anything for the theory.
I am not super confident in anything I said here, although that’s mostly because I have an outside view that tells me consciousness is hard to get right. My inside view tells me that I am probably correct, because I just don’t see how positing mental stuff that’s separate from mathematical law can add anything whatsoever to a physical theory.
I’m happy to talk more about this some day, perhaps in person. :)
