"What did Kant assert in 'Of the Deduction of the Principles of Pure Practical Reason? He made the deduction of Pure Concepts of the Understanding in the ""Critique of Pure Reason."" It demostrated that the Categories had the objective validity in the empirical knowledge, because they were the conditions of experience. It does not go well similarly with the deduction of the Principles of Pure Practical Reason. Though the Law of Morality stands fast as the fact of Pure Reason, how it has the objective validity in practice cannot be proved. But from this fact, the deduction of Freedom becomes possible. The Possiblity of the freedom of will was allowed in the critique of theoretical reason, but the substance of freedom was not determined. So when the Pure Practical Reason determines the substance of freedom by its law.the freedom gets its contents,and real meaning. At the same time through the realizatron of this free will the Moral Law gets its objective reality. So the Reality of the Principles of Pure Practical Reason is demonstrated by the Possibility of the deduction of Freedom,though the direct deduction of those principles is impossible."
