DEDUKCIJA MORALNOSTI I SLOBODE U KANTOVOJ ETICI
DEDUCTION OF MORALITY AND FREEDOM IN KANT’S ETHICS

Summary/Abstract: In the third section of the Groundwork of the Metaphysics of Morals, Kant seeks, on the basis of the idea of the necessary presumption of freedom, to provide a deduction of the supreme moral principle and to prove its objective validity. Three years later, in the Critique of Practical Reason, he explicitly denies the possibility of making such deduction, and by changing methodological assumptions, tries to show that awareness of the moral law as a fact of reason is the basis for the deduction of freedom. In this paper we will argue that a direct contrast between Kant’s two texts clearly shows that a radical shift in his thought has taken place. The purpose of this text is to show that Kant had reasons to be dissatisfied with the deduction of the moral law offered in the Groundwork of the Metaphysics of Morals, which led him to change his argumentative course when writing the Second Critique.
