The Conceptual Incoherence of "Outside Experience": Why Materialism's Ontological Profligacy Approaches Logical Impossibility

This paper demonstrates that "outside experience" occupies at best razor-thin conceptual space. The margin between "does not exist" and "has zero experiential impact ever" is effectively zero. We establish this through conceptual analysis of what "effectively" means, when distinctions stop making differences, and what work terms like "might have but didn't" actually do. Building on Experiential Empiricism's foundational axioms (Sergent, n.d.-a), we show that existence claims derive their meaning entirely from experiential access. Something with no experiential signature across all possible experience occupies conceptual space so thin it might as well not exist. Materialism becomes the primary example of cosmic commitment to this functionally-empty space: positing potentially infinite matter and energy with zero experiential impact ever, treating it as more fundamental than experience itself, and using this posited vastness to dismiss the significance of actual experiencing. The result reveals ontological profligacy that builds everything on conceptual space that is functionally worthless.
