Non ex se: On Derivation, Present Actuality, and Why the Ground Is Not Merely First

Non ex se examines the thesis of existential inertia: the claim that although a contingent being may require a cause in order to begin existing, it need not depend upon any cause in order to continue existing. The essay returns to an earlier claim of the Gaitan Topology — that creaturely actuality is constitutively, rather than merely historically, dependent upon the Non-Derivative — and asks whether that claim has been earned rather than merely asserted. The argument distinguishes inherited determination from present actuality. Numerical identity, causal continuity, dispositions, laws, history, and other inherited determinations can explain how a continuant persists as the continuant it is. But each already presupposes an actual subject and therefore cannot, without explanatory reversal, account for the subject’s being-actual at the crossing itself. The conclusion is deliberately limited. Given the topology’s distinction between that a thing is actual and how it is determined, together with its prior refusal to treat contingent being-actual as brute, per-crossing constitutive dependence follows. The essay does not claim to compel every metaphysician: the reader may reject either commitment. Its purpose is instead an internal audit, showing why the Ground of present actuality cannot be merely a first cause within, or at the beginning of, succession.
