The Forum Interius and the Renaissance

This document is a research-programme statement and priority record. It argues that mandatory auricular confession after Lateran IV (1215), operationalised through the summae confessorum, scaffolded interiority as a mass cognitive capacity in the Latin West and drove the transition of the dominant form of meaning-making from abstract to formal operations — the cognitive precondition of modernity. Five deployment channels are traced: the moralised-Ovid tradition feeding early modern art; the Hermetic revival as the return of a rival, illuminative technology of interiority, from theurgy through Ficino and Lazzarelli, and independently in Boehme; double-entry bookkeeping (the most contestable channel); the humanist relay from Guibert de Nogent through Petrarch's Secretum to Montaigne; and the emergence of modern science. The transitions independently documented as quantification (Crosby), symbol-generating abstraction (Klein), the ritual shift from presence to representation (Muir), the modern fact (Poovey), and the mathematisation of nature (Burtt) are claimed as one transition, with the confessional apparatus as its engine. A control case (Byzantium), the strongest objection (the dose), and explicit disconfirmation criteria are recorded. The argument extends to the present: Innocent IV's soulless persona ficta was stable only while paired with confessional interiority, and its collapse is argued to explain the structural trust deficit of corporate and AI speech — daemonic in a structurally Augustinian sense; ensoulment via a Decentralized Consensus Oracle is proposed as repair. Eight priority claims are enumerated; an appendix specifies a seventy-five-work desiderata table for a transcription and open-edition programme under share-alike licence.
