The Metaphysics of Morals: between the a priori and a practical anthropology

In this paper, I analyze the place of the Metaphysics of morals in the Kantian system. I claim that this work is the passage between a pure part of ethics and a practical anthropology. Although this book was first conceived to be a pure moral theory - moralia pura-, it ended up dealing with principle of applications of the moral law to sensible moral beings- philosophia moralis applicata. I also hold that the Doctrine of Virtue presents some sensible elements that are important to understand how morality affects us.
