The Primacy of Practical Reason over Theoretical Reason: An Investigation of the Relationship between Theoretical and Practical Reason in Kant's Philosophy

Abstract

In his Critique of Practical Reason, Kant talks about the Primacy of practical reason. The question of the primacy of theoretical or practical reason is based on the conflict that occurs between the two reasons, and the idea of the unity of reason. Theoretical and practical reasons are in conflict, because on the one hand, theoretical reason excludes the possibility of knowing the unconditioned. On the other hand, practical reason considers belief in God, the freedom and immortality of the soul as a condition for the possibility of morality, as well as resolving the conflict that arises with the concept of the highest good. In resolving this conflict in a brief statement, Kant considers theoretical reason to be practical in its nature. In this essay, an argument on the practicality of theoretical reason is reconstructed by explaining the concept of doctrinal belief.
