The Limit of Logic: A Structural Realist Reformulation of the Ontological Argument

Classical formulations of the ontological argument, most notably that of Anselm of Canterbury, have long faced the objection that existence cannot be derived from definition alone. Following Immanuel Kant, existence is typically regarded as a non-predicative feature, thereby undermining attempts to infer reality from conceptual analysis. This paper proposes a reformulation of the ontological argument grounded in Ontic Structural Realism. It argues that, under a structuralist interpretation of reality, a maximally complete explanatory structure cannot fail to be instantiated. By introducing a bridge principle connecting maximal explanatory completeness with metaphysical necessity, the paper defends a revised ontological argument in which the distinction between conceptual coherence and ontological existence collapses at the limit of logical structure. The result is not a definitional proof of existence, but a claim about the conditions under which explanation itself is possible. This paper sets the scope, the main proposition, and the principal line of argumentation. Further arguments and the continued development of the thesis are presented in two companion papers: "The Multiverse Paradox: Reductionism, Mathematics, and Existence as a Predicate" and "Can Something Create Nothing - Nothingness Through the Lens of Ontic Structural Realisme", where the thesis reaches its conclusion.
