This article has two objectives: first, to bring to the fore Kant's neglected distinction between ‘critique’ and ‘doctrine’ and, second, to relate this distinction to Kant's notion of a philosophy of right. Kant's culminating contribution to practical philosophy, the Metaphysics of Morals, contains a doctrine of right and this ‘doctrine’ has received relatively little attention thus far in English-language writing on Kant. One of the reasons for this relative neglect is, I believe, due to the prevalent attention provided to Kant's (...) practical critique at the expense of his practical doctrine. I aim to provide an account of Kant's critique of right in order to enable an understanding of Kant's doctrine of right to be provided with some initial orientation. I will be suggesting that this critique of right is presented in Toward Perpetual Peace: A Philosophical Sketch. (shrink)
