The dignity of humanity and the duties in Kant's work

This main aim of this study is to discuss the plausibility of two criticisms generally addressed to Kant's Ethics. The first one is that Kant's Ethics is purely formalist, and the second criticism is that, precisely because of this formalism, Kant's Ethics neglects the role of virtue in moral life. It holds that the dignity of humanity brings content to the justification of the human rights and helps to build up a Doctrine of Virtue (ethica, in Kant's sense). In this way, it concludes that Kant's project of a Metaphysics of Morals can answer the objections mentioned above.
