Abstract
In this paper I shall show that Kant's best anti-sceptical argument, found in the “Refutation of Idealism” — hereafter Refutation —, is not successful in debunking the sceptic. My strategy will be to argue that, although dependent upon transcendental idealism, the Refutation is inconsistent with it. In order to achieve this goal, I shall sketch, in section 1, the two main interpretations of Kant's idealism, namely, the ‘two world’ and the ‘two aspect’ theories. I shall maintain that the latter is more in keeping with Kant's overall intentions in the Critique of Pure Reason. In section 2, I shall spell out the main points of the Refutation. In section 3, I shall argue that, in the context of the Refutation, the conception of the permanent as the pre-condition of any temporal sequence clashes with some of the main doctrines of transcendental idealism. Finally, in section 4, I shall follow some unsuccessful attempts to harmonise transcendental idealism with the Refutation.
