La Profilée - The Human Person as a Structural System

Paper 89 established that personal identity is structurally determinate under La Profilée’s (LP) persistence condition IR = R / (F·M·K) ≤ 1, and identified the operationalization of Frame (F) for persons as an open question. This paper closes that question in three steps. First, F, M, K, and R are operationalized for the human person with a concrete indicator set: F as self-referential structural integration, M as transformation-processing capacity, K as coupling coherence between Frame and Module, and R as total transformation load. Each variable is defined with independently observable indicators satisfying the Operational Closure Principle. Second, the operationalization is grounded in empirical developmental psychology. Luyckx et al.’s (2008) dual-cycle model of identity formation and Marcia’s (1966/Kroger & Marcia, 2011) identity status framework provide a well-validated empirical base from which F, M, K, and R can be independently estimated. The adolescent identity crisis — the transition from Moratorium to Identity Achievement — is analyzed as a structural case: IR rises above 1, F remains above F_crit* throughout, and IR returns to ≤ 1 at reintegration. LP’s verdict (same person throughout) is structurally derived and contrasted with Parfit’s framework, which cannot account for the persistence verdict without additional stipulation. Third, structural phenomena — mental illness, development, identity crisis, and death — are shown to be unified configurations of F, M, K, and R rather than independent categories. The result is a complete, empirically grounded structural account of personal persistence. The human person is not an exception to the LP persistence condition. It is its most revealing case.
