The division of Kant's practical philosophy

Kant's practical philosophy costitute a systematic whole whose proposals are organized or structured in three major disciplines: in first place, we find what may be denominated as pure ethics, which con-tains the ultimate ground of morality and, therefore, of the practical rationality; in second place, there is a metaphysics of morals, whose mission is to contain the system of laws of the practical reason, and, finally, practical anthropology, a discipline that give us every empirical knowledge that favor or hinder moral development of human beings.
