The ground of beings cannot be a being: a grounding-theoretic argument

Abstract What grounds the existence of beings? This paper argues that if the existence of beings (rather than nothing) admits of an account and grounding is irreflexive, the ground of beings cannot itself be a being. The argument proceeds by elimination. If we ask what accounts for there being anything at all, four options present themselves: the ground is among the beings it grounds (self-grounding), there is no ground (brute fact), there is an infinite regress of grounds, or the ground is trans-categorial. Self-grounding generates incoherence: it violates grounding’s irreflexivity, collapses into explanatory vacuity, and produces priority inversion. Brute fact, while coherent, denies that the existence of beings as such admits of any account. Infinite regress defers explanation without terminus. What remains, for those who hold that reality is ultimately intelligible, is a ground outside the domain it grounds: not an entity among entities. This conclusion aligns with classical theism’s doctrine that God is ipsum esse subsistens : not a being that exists, but subsistent existence itself. The argument establishes a structural place that classical theism recognizes as “God.”
