An Onto-Axiological Argument for the Existence of God

Abstract

The article presents an Onto-Axiological Argument for the existence of God, formalized in first-order logic. It combines ontological and axiological principles, arguing that God is superior to all other entities in all relevant aspects, including the aspect of being. The existence of contingent entities is an a posteriori premise of the argument, which culminates in a formal demonstration of God’s existence in act. The consistency of the underlying theory is demonstrated through a very simple model, and its interpretation is succinctly discussed in relation to Aristotelian-Thomistic metaphysics, although it is applicable to other philosophical contexts. The argument seeks logical rigor and conceptual clarity, offering a novel contribution to debates on the existence of God.
