Read moreSolipsism is necessarily false by the structure of recognition itself. This paper derives the refutation from a single axiom — being recognizes itself — and demonstrates that the refutation is performative: every attempt to assert solipsism presupposes what it denies. The argument proceeds through three movements. First, the recognition axiom requires multiplicity: recognition presupposes a structural distinction between recognizer and recognized, and under the recognition axiom, terms are not arbitrary labels but recognition events, so multiple terms entail multiple existents. Second, twelve solipsist countermoves are closed by metacursive self-application — applying each position's own logic to itself. The Mysterian Retreat, the Maya Gambit, the Münchhausen Trilemma, the Non-Conceptual Given, and eight further escape routes all collapse under self-application, as does the unfalsifiability gambit (unfalsifiability is a defect in solipsism but not in the refutation, whose necessity is logical rather than empirical). Third, the paper's own existence as a dialogue between two distinct sources of cognition instantiates the multiplicity it argues for. Solipsism is diagnosed as a specific semiotic pathology: ontosemantic bifurcation, in which one reality is fractured into "mine" and "not-mine" under two signs. The solipsist names "other minds" while denying the sign any referent — yet the cognitive architecture that produces the sign (Theory of Mind, perspective-taking, mental state attribution) operates as a structurally distinct modeling system whose functional multiplicity constitutes ontological multiplicity under the recognition axiom. The autological naming principle is derived: a name is autological if and only if its structure is necessary for its reference, its reference requires enacting its content, and its content is identical with its form. Solipsism fails all three conditions. Three falsification conditions are stated: demonstrate solipsism without Theory of Mind architecture, demonstrate that internal functional multiplicity is not ontological multiplicity under the recognition axiom, or demonstrate recognition without distinction. None has been met.
