Philosophy of mind · a map
Every theory of consciousness answers two questions. Is the mind computable — could a program, on the right substrate or any substrate, be one? And once you've mapped the mechanism, does anything remain unexplained? Plot those two axes and three centuries of the debate fall into place — Descartes's non-physical mind and Turing's imitation game at opposite corners, the hard problem strung across the top, and a single Gödel theorem read in two opposite ways.
How to read this map
So the four corners read: irreducible mystery (top-left) · buildable but unexplained (top-right) · new physics dissolves it (bottom-left) · mind is mechanism / pattern (bottom-right).

The dossiers
Each card distills the thinker's position in our own words — editorial characterizations, not verbatim quotations (aside from a few well-known published lines).
“Mathematical understanding is non-algorithmic — Gödel shows the mind outruns any formal system. Consciousness is orchestrated, gravitationally-induced quantum collapse in neuronal microtubules: new physics, not computation.”
“‘You’ are no more than a vast assembly of nerve cells and their molecules. Map the neural correlates — gamma synchrony, the claustrum as conductor — and the soul dissolves into mechanism.”
“The self is a substrate-neutral strange loop — a symbol system that models itself. Gödelian self-reference doesn't defeat the machine; it's exactly what turns one into an ‘I’.”
“Swap neurons for functional silicon and experience can't quietly fade or invert — organizational invariance. The copy is conscious. Yet no mechanism explains why there is experience at all: the hard problem.”
“The felt ‘extra’ is a user illusion. Account for every function — discrimination, report, control — and there is simply nothing left over to explain.”
“Consciousness is integrated information — Φ, a system's intrinsic cause-effect power. A feed-forward digital copy can match the behaviour with near-zero Φ, so it would not be conscious.”
“A program shuffling symbols by rule has syntax but no semantics — the person in the Chinese Room follows every rule yet understands no Chinese. Software isn't understanding; consciousness is a real biological power of brains.”
“There is something it is like to be a bat — a subjective point of view that no third-person, objective description reaches. Physical science leaves out the very feature that makes a state conscious.”
“Content becomes conscious when a global workspace broadcasts it to the whole system — perception, memory, report. Consciousness is a specific, findable information-processing architecture.”
“The ‘ghost in the machine’ is a category mistake. Mind isn't an inner theatre behind behaviour — mental talk names dispositions to act. Hunt for an extra inner thing and you've misread the grammar.”
“Don't ask whether a machine can think — ask whether it can play the imitation game so well you can't tell. If its behaviour is indistinguishable from a mind's, the only workable convention is to grant it one.”
“Mind and body are distinct substances — a thinking thing that is not extended matter. The ‘I’ that doubts cannot itself be doubted, and no mere mechanism could ever be it.”
“Rather than conjure experience from dead matter, take it as fundamental — a basic feature of the physical, present in some form all the way down. The gap closes because there was never a leap.”
“Pull apart two things ‘conscious’ blurs: access-consciousness — information poised for use and report — and phenomenal-consciousness, what it is like. A system can have the first with none of the second.”
“The felt inner life is a theory — folk psychology — and a false one. There are no qualia to explain; as neuroscience matures, talk of them will follow phlogiston and caloric into disuse.”
Three through-lines
The empirical programs meet on one puzzle: how scattered activity becomes a single field of experience. Crick's gamma synchrony and claustrum and Orch OR's quantum entanglement are rival mechanisms for the same unity — reductionist and quantum camps aiming at one target.
One theorem, two verdicts. Penrose: a mind sees truths no formal system can prove, so it can't be one. Hofstadter: a formal system rich enough to talk about itself is precisely what a mind is. The same self-reference is read as escape, and as origin.
Chalmers' solvent: neural, computational, or quantum — no mechanism entails why it should feel like anything. It's what lets him reject Penrose (“one mystery for another”) and the reductionists alike. Working ≠ understanding.
The one thing the extremes agree on: a program that works is not the same as an account of why it's conscious — Penrose because he thinks the working program is impossible, Chalmers because he thinks it would be insufficient. Everyone between them is a bet that mechanism, once found, is the whole story.
