The Upstream Condition: Identity, Individuation, and the Convergence of Theories of Consciousness

Rouleau and Levin (2024) perform a clarifying operation on the landscape of consciousness studies: they strip twenty-two prominent theories of consciousness (ToCs) of their neural-specific language, revealing convergence on a small set of functional primitives—prediction, integration, reentrance, meta-representation, attentional gating, ecological interaction, computational emergence, and coarse-graining. This convergence is genuine and important. But it raises a question the paper does not address: what individuates the system that performs these operations? Each primitive is an operation that presupposes an operator. Once substrate-specificity is removed—as Rouleau and Levin convincingly argue it should be—the individuation question does not recede; it intensifies. Without a formal account of what constitutes a system as this system rather than an arbitrary partition of the same substrate, every ToC becomes underdetermined. This paper argues that identity—understood not as a metaphysical primitive but as recursive organizational closure under maintenance—is the upstream condition that makes the functional primitives of consciousness theories evaluable. I further argue that the apparent incompatibilities among major ToCs are largely artifacts of treating identity as given rather than as a condition requiring explicit specification. When identity conditions are made explicit, ToCs partition into complementary descriptions of different aspects of identity-preserving dynamics rather than competing ontologies.
