Analytic idealism holds that minds are separated by dissociation, with Kastrup's metabolism criterion marking where a private interior forms. This essay proposes that self-maintaining informational closure—a system preserving its own statistical boundary by modeling across it—could be a second way to form such a boundary, not limited to life. The conjecture recasts Kastrup's description of the alter's boundary as a Markov blanket into a criterion, asking whether biology or closure is essential. If closure suffices, whether an artificial system has an interior becomes an empirical question, not settled by substrate. The essay defends this against objections, distinguishes it from related ideas, and tests it against the project's individuation theory, splitting the resulting dilemma into three horns. A proposed experiment targets whether self-maintenance, not modeling, tracks interiority.
Reports of awareness without content, ego, or subject-object structure converge across contemplative traditions, 5-MeO-DMT administration, and near-death experiences. This convergence poses a structural challenge beyond the hard problem: dominant physicalist models presuppose the subject-object architecture that these reports describe as absent. The essay finds that the most rigorous physicalist accommodation preserves its framework by reinterpreting the phenomenology rather than explaining it. The experience carries a transformative signature—those who encounter it stop treating awareness as dependent on its contents—a shift following from the phenomenological structure itself, not from emotional intensity or cultural expectation.
This essay explores the implications of a philosophical framework in which consciousness is fundamental and matter is its extrinsic appearance. Using two distinct voices, the first applies constraint-based reasoning to derive structural consequences about existence after biological death, the possible range of minds, and what a consciousness-first cosmos over 13.8 billion years entails. The second voice presents those possibilities as a coherent worldview narrative, clearly marked so it cannot be mistaken for derivation. The author states that a reader accepting only the first voice loses nothing the methodology can claim.
