stablishing an efficient moral discipline depend on the accurate and comprehensive recognition the human nature, as the morality subject, what we regard the human and his nature, is the necessary Precondition to found a moral system: knowing him a wicked creature by nature, or treating him as an existing belonging to both sensible and rational world, which an aspect of his nature appears in any areas. In the Kant's receiving, human is not a mono-dimension of being, but he is the citizen the both worlds: sensible and rational universes. The human is good as the basis his rational nature, and bad on the basis his sensible nature. So he emphasize, in the Groundwork of the metaphysics of moral: "Now because the world of understanding contains the ground of the world of sense and so too of its laws, we must suppose that in our capacity as members of the World of understanding, we give laws to ourselves as members of the World of sense. And this is what gives us obligations". The necessity of founding the morality on anthropology-which in Kant's viewpoint is an empirical science in methodology-on the one hand, and the possibility of establishing a pure moral philosophy which is quite free of any empirical element, on the other hand, causes some interpreters doubt whether Kant has really been able to found such a moral system. Therefore the present research intends to consider the anthropology regarding to morality in the Kant's philosophical discipline, in order to reveal the purity of his moral philosophy and also detect the way it bases on the anthropology.
