The Gageian Epistemic Model: Dissolving the Agrippa Trilemma with the Structural Mandate for Warranted Belief (V10)

The Pyrrhonian Skeptic’s Agrippa Trilemma asserts that any knowledge claim is doomed to infinite regress, arbitrary dogmatism, or circular reasoning. This paper argues that the Trilemma is an axiomatic consequence of the historical reliance on the problematic Justified True Belief (JTB) definition and the failure to rigorously define the necessary structure of conscious inquiry. This paper introduces the Gageian Epistemic Model (GEM), a descriptive meta-epistemology that formalizes the mandatory procedure of conscious warrant into the PIE Sequence (P1-P5). The GEM offers a unique, structural response to the Trilemma: the infinite regress is terminated by the self-vindicating, structurally mandated axiom, P1: The Axiom of Subjective State (S). Arbitrariness is overcome by demonstrating the structural necessity of P3 (the Goal of resolution), and circularity is controlled by establishing two distinct, warranted standards for belief. The GEM formalizes all warranted belief across two categories: Intrinsic Knowledge as Justified Coherent Belief (JCB), warranted by internal coherence via P4, and Extrinsic Knowledge as Justified Reliable Belief (JRB), warranted by external predictive success via P5. This axiomatic procedure provides the foundational justification for the methodology of modern science and mathematics, proving it is the only structurally defensible path available to a conscious agent.
