Part III: Categorical Phenomenology

Sector S_E (Empirical), Part 2 of 2. How do we know? Knowledge is sections over experience—justified belief is sheaf gluing; perception is constraint filtering. Temporal experience has a threefold structure: retention, primal impression, protention. Intersubjectivity grounds objectivity through perspectival gluing. The lived body (Leib) is the phenomenological ground of all experience. The epistemology/ontology distinction dissolves: knowing and being are the same categorical structure viewed from different angles. Husserl and Merleau-Ponty meet category theory. Together with Part II, the empirical sector S_E covers what classical philosophy calls ontology and epistemology—the two domains governed by the register question “what do I observe?”
