The Case

The bar every total theory faces

Any theory that claims to describe everything — and to place its own theorists, and their experience, inside what it describes — faces demands that can be stated without reference to any particular candidate. It has to be coherent: consistent, its constructions well-defined, its primitives declared rather than smuggled, its rules applied uniformly, its explanations grounded. It has to be anchored: a theory that attributes only abstract structure to the world says almost nothing, because any collection of the right number of things can be arranged to instantiate any abstract structure — the century-old Newman problem — so something must tie the theory’s structure and its central terms to reality. And it has to be complete: it cannot go silent on how determinate facts arise, on why some processes have an inside — something it is like to be them — or on where its own theorists sit, and still count as a theory of everything.

The completeness demands are not a wishlist. They are forced by a single requirement — that the theory seat its own theorist inside the world it describes. Unpack what it takes for a theorist to exist, and the domains a total theory must address fall out as consequences: a theorist persists and changes, carries memory, registers determinate facts against a field of alternatives, has or on principle lacks an inside, and acts. A standalone paper derives this net of conditions on its own terms, before any candidate is named.

The pattern

Run the current families of total theory through that net and a pattern appears: most illuminate one region of reality and go dark on another.

clears partial or contested silent.   Left of the divider, whether the theory covers the world it describes; right, whether it seats its own theorist. Graded from each account's strongest defended version; the coherence conditions and the full grading are in the papers below.

Physics-first accounts cover the world and its content and go dark on the theorist, on how determinate facts arise, and on the inside. A mind-first account, Integrated Information Theory (IIT), is the mirror image: it speaks to the inside and leaves the physics dark. A form-first account holds that structure is fundamental and cannot anchor it. Each lights a region; each leaves regions dark — and the two halves cannot simply be stapled together, because a physics-first base and a mind-first base share no common ground to join along.

The shape of an answer

What kind of theory could carry the physics and still say something principled about experience? The hard problem’s usual moral is that nothing would even count as an answer. That moral is too strong: what an answer would have to look like can be derived before any candidate is named. The second paper below derives the shape: a theory that answers every demand by account, rather than by explaining something away, must carry both an intrinsic and an extrinsic aspect — an inside and an outside — in its fundamental ingredients, must apply its own dynamics to the theorist doing the theorizing, must fix what “actual” refers to from inside itself, and must rest on well-defined mathematics. The derivation states its conditions plainly, and it identifies the century-old near miss: Whitehead’s process ontology carried the shape and lacked the mathematics. The search space for a total theory is narrower than the discourse assumes.

The two debts the shape incurs

A theory of the forced shape does not get its hardest commitments for free. Carrying both aspects in the basic ingredients, on the many-bearers horn Whitehead occupied, creates exactly two debts — and each now has a paper arguing it is payable, on its own terms, before the candidate is graded.

Both debts turn on a single identity, and it is the framework’s most consequential claim — so it is worth stating plainly, rather than letting it accumulate out of the argument. Projective Process Monism holds that one geometry underlies both the physical world and the structure of conscious experience: the space the physics runs on, which the framework calls actuality, is the same space in which experience is laid out. This is a claim the framework makes and argues for — the argument is developed in the third paper. It is a proposal about how the physical world and experience relate, one the framework puts forward to be defended and tested.

One thing keeps that from being a claim of convenience. The same projective structure was reached from the opposite direction: modeling the geometry of visual experience, Rudrauf and colleagues (2017) arrived at the same projective form, with no physics in view. Two independent routes, one shape. The framework treats that convergence as a starting point worth taking seriously — a reason to build on the identity and test it. A coincidence this specific earns a closer look, and it leaves the question open.

The candidate, measured

The fifth paper runs Projective Process Monism through the net. It seats its theorist by construction: the observer is a process inside that one geometry, so — on the identification set out above — experience is the inside of the very event that measurement describes from outside. It keeps one rule across quantum measurement and conscious experience, with no special exemption for either, and the arrow of time falls out of the accumulation of records rather than being posited by hand. It fixes what it means by “actual” inside its own geometry, so its central terms are anchored rather than free to be reinterpreted. And it takes a principled position on every domain the net names — held to the same standard as every rival. It is also a realization of the shape derived above: an ontology of events each carrying both aspects, with the formal object the second paper identifies as history’s missing piece supplied by the geometry itself.

The assessment keeps its ledger honest. Where the framework’s position rests on a posit — the monist identification, the evidential read — the fifth paper prices it as a posit and points at the companion that argues it, rather than grading it as settled. Most accounts do not manage the span together — seating the theorist, one uniform rule, anchored reference, a position across the whole net. That coverage takes a single arena whose one base reaches both the world and the inside.

What that does, and does not, establish

Clearing the net does not make the framework correct. It makes it an account of the right structural kind — a candidate that meets the conditions any total theory must, rather than one that reaches breadth by exemption or leaves regions blank. Its open items are quantitative debts inside domains it already addresses: some particle masses not yet computed from the geometry, the primordial fluctuation spectrum, a small residual in the gravitational constant, and a dark-energy model currently in tension with recent survey data. And it stakes itself on measurement — physical constants derived from a single measured scale, and live predictions that observation can falsify.

The claim here is deliberately bounded: this belongs in the conversation about total theories because it meets the structural bar and puts numbers at risk. Whether it is true is settled elsewhere, by those measurements.

Read the argument

The full development is in five short papers, and the order is the argument: the bar, the shape it forces, the two debts that shape incurs, and the candidate measured against all of it. The first two name no candidate. The middle two argue the debts payable. Only the fifth grades the framework.
