Abstract
In his critical writings before 1786 Kant argues that trans¬cendental freedom is a problem for speculative philosophy and that this problem was solved satisfyingly in 1781 by his own Transcendental Idealism. In the Groundwork, 1785, after having linked the moral law inseparably to transcendental freedom by his discovery of autonomy, Kant claimed that the moral law can be deduced from freedom thus established. But in May 1786 he was persuaded by a review-article that his 1781/85-deduction of freedom was incompatible with his critical philosophy. Hence Kant had to shift the epistemic priority from freedom to the moral law. He thus replaced the deduction of freedom and morality given in the Third Part of the Groundwork by his Doctrine of the fact of pure practical reason in the 2nd Critique. By this move Kant established an entirely new and dominant role for practical reason in metaphysics, a role which already shows up in the second edition of the 1st Critique and which leads to Kant′s unprecedented conception of a praktisch-dogmatische Metaphyik in the 1790ties
