Determinism and Human Freedom in Kant's Critical Philosophy

The relationship between determinism and human freedom remains one of the enduring debates in metaphysics and moral philosophy. This study critically examines Immanuel Kant’s critique of determinism and his account of human freedom within the framework of transcendental idealism. Employing a qualitative philosophical methodology based on conceptual and textual analysis, the paper evaluates Kant’s arguments in the Critique of Pure Reason and the Critique of Practical Reason concerning causality, freedom, and moral responsibility. The study argues that Kant neither embraces strict determinism nor libertarian indeterminism in their conventional forms. Rather, he reconciles causal determinism in the phenomenal world with the autonomy of rational agents in the noumenal realm, thereby providing a philosophical foundation for moral responsibility. While Kant’s solution remains one of the most influential responses to the freedom-determinism debate, it continues to attract criticism regarding the coherence of the distinction between appearances and things-in-themselves. The paper concludes that Kant’s critical philosophy remains indispensable for contemporary discussions on free will, causality, and moral agency, while inviting renewed engagement with recent developments in metaphysics and ethics.
