Can phenomenal consciousness be identified with a structure already present in classical spacetime geometry? This paper develops and critically examines an intrinsic causal geometry hypothesis: the phenomenal type of an appropriately selected episode is identified with the isometry class of its chronological order and full four-volume measure. In a suitable class of distinguishing Lorentzian...
A recent proposal in the structural approach to consciousness [Lee-Youngzie, Tsuchiya, Robinson, Dietz & Monti, Entropy 28 (2026) 615] models the phenomenal unity of experience sheaf-theoretically: experiential parts form a finite topological space, empirical measures of their qualia form a presheaf of dissimilarity structures, and unity is the gluing of local sections into a global one. The...
