Does Consciousness Require Metabolism? A Kripke-Style Philosophical Exchange
dioscuri · x · 2026-10-21
A philosophical exchange on the nature of consciousness: the author asks whether the claim "consciousness requires metabolism" is a priori or a posteriori. A priori seems false—one can conceive of conscious beings lacking metabolism (e.g., Commander Data).
He then considers it as an a posteriori necessity in the vein of Kripke's "water = H2O." But the analogy fails: we accept water = H2O because the molecular structure explains water's features (e.g., liquidity), whereas metabolism explains no notable features of consciousness. Directly relevant to debates over machine consciousness.
