Causality as a Metalogical Necessity: A Transcendental Defense

This paper argues that causality is not merely an empirical principle or a fundamental logical law but a metalogical necessity—a precondition for the very possibility of thought, reasoning, and logical consistency. Unlike traditional defenses that treat causality as an external feature of reality, this argument demonstrates that the very act of thinking presupposes causality. Without causality, structured thought collapses, rendering logical laws such as the law of noncontradiction (LNC) and the law of identity (LI) unintelligible and unreliable. Thus, causality is prior to logic itself, making it the most fundamental epistemic condition for knowledge and rational discourse.
