Ito, Daigoro: Compression-Stable Multiplicity: Conditions for Meaningful Individuation in Multiverse Discourse

Multiverse theories are frequently invoked at points where single-universe explanations appear insufficient to account for fine-tuning, contingency, or cosmological variation. Yet discussions concerning the number, probability, or explanatory role of universes often proceed without first establishing whether the alleged multiplicity is conceptually well-formed. This paper argues that individuation conditions are logically prior to meaningful multiplicity claims, and that without explicit criteri
