Human right is one of the complicate problems of international society. The main difficulty is to define the ambiguous meaning of human rights. This paper intends to find the possible requirements concerning the definition of “human right”. For Kant is the idea of human right an important consequence of his moral theory. The being of human, his Freedom and autonomy, is the intrisic reason for the right. We'll see in this paper, whether Kant's interpretation can fullfill our requirements. Today, for developmenting our idea of human right, which should be theoretical cosistent and practical realistic, is Kant's standpoint still very interesting and helpful.
