<p>Debates on selfhood typically locate its basis either in the minimal experiential structure of consciousness or in the representational mechanisms underlying de se thought. Both approaches treat selfhood as a matter of content—phenomenal or conceptual—and thus overlook the organizational conditions that make such content possible. I argue that neither the lived “for-me-ness” emphasized in phenomenology nor the first-person mode of presentation emphasized in analytic philosophy can ground individuation, since each presupposes an antecedent asymmetry already built into the system’s architecture. I develop an alternative account in terms of origin-tracking: a structural invariant through which a system differentiates self-generated from externally generated events and coordinates perception, action, and integration around a privileged standpoint. Origin-tracking is not representational but organizational; it individuates the subject by establishing the conditions under which perspectival experience and de se representation can arise. Minimal selfhood and first-person thought emerge as complementary expressions of the same architectural asymmetry rather than as its source. This structural account clarifies the unity of agency, pre-reflective selfhood, and first-person cognition without positing a substantial ego or higher-order representation, and it explains both the fragility of subjectivity in pathological cases and the continuity of the subject across time.</p>
