Chapter 31: Solipsism Resolved: Three Layers

Three-layer resolution of solipsism. Layer 1 (Ontic): collapse to ω produces monism with internal distinctions—solipsism is trivially true (there is only one structure) and structurally vacuous (the “I” is not privileged within it). Layer 2 (Epistemic): uncertainty provides an epistemic witness for other minds—a system that models its own modeling (E₃) necessarily encounters uncertainty about other modelers, which is an epistemic signature of other minds. Layer 3 (Bayesian): under finite computational resources, solipsism is Bayesian-excluded as maximally implausible. The dissolution: solipsism is not refuted but shown to be an artefact of substance ontology—in relational ontology, the “self” is a relational position, not a substance, so “only my self exists” is structurally incoherent.
