Perspectival Informational Individuation: Identity Persistence Under Transformation

This preprint introduces Perspectival Informational Individuation (PII), a conceptual and methodological framework for studying how dynamically organized systems can persist as the same individual under transformation. PII treats identity persistence as a relational property between an admissible mode of organizational resolution and the dynamics that sustain the corresponding invariants over time. The framework is organized around four constitutive conditions: informational emergence, perspectivism, a structured relational possibility space, and transformation-sensitive coherence. It also proposes constraint-information reciprocity as a strengthening condition for systems whose persistence involves endogenous modification of their own constraint architecture. PII does not address the prior emergence of systemhood. When situated within the broader Theory of Informational Emergence (TIE), it operates at a post-emergence analytical level: TIE concerns the conditions under which informational systems arise, whereas PII concerns how the persistence of their organization can be investigated across admissible modes of resolution. A central empirical commitment of the framework is that different admissible perspectives may identify distinct transitions within the same underlying process, while those transitions may nevertheless exhibit reproducible temporal, conditional, or dependency relations. Conversational dynamics are proposed as one prospective empirical testbed for this claim.
