Explanatory Simplicity Theism (EST

This paper introduces a novel proposal within the philosophy of religion, termed Explanatory Simplicity Theism (EST) or Axiomatic Theism. Unlike classical theism, deism, or process thought, EST conceives of God not as a personal or relational being, but as the minimal, ultra-simple, logically necessary ground of all that exists. The foundation of this model is the Principle of Ultimate Explanatory Simplicity (PUES), which posits that metaphysical explanation must terminate in the simplest sufficient ground possible which one that sustains all existence by necessity, not by intention or volition. This sustaining principle is non-contingent, non-relational, and metaphysically isolated, serving as an axiomatic terminus to infinite explanatory regress. Through rigorous formalism in modal logic and ontological parsimony, EST seeks to offer a new theistic framework that directly responds to longstanding critiques from naturalistic and analytic traditions. It represents a radically minimal yet metaphysically robut vision of divinity grounded in necessity and clarity.
