Systematic unity of reason in the Critique of Pure Reason and the Critique of the Power of Judgment

Abstract

Systematic unity of reason for Immanuel Kant is a matter of all or nothing. This article aims to analyze the notion of systematic unity of reason in the Critique of Pure Reason and its reformulation in the Critique of the Power of Judgment in order to give unity to reason in its theoretical and practical uses. First, we review the systematic unity according to the Transcendental Doctrine of Method. Second, we review the Appendix to the Transcendental Dialectic as a possible, but problematic candidate for the unity of reason. Third, we briefly show the transcendental principle of purposiveness of reflective judgment as apt to give unity to nature and freedom and to fulfill the practical requirement of the cosmic concept of philosophy
