It is interesting for our investigation into the meaning of moral to follow the unique and queer thought about the moral of Autrui (otherness) by Levinas.His paradoxical theory about the essence of moral is quite surprising to us. His thought is certainly a being like a mine layed in the field of moral. If his theory has any reasonable ground, we should probably reexamine the meaning of moral, and reexamine its categories. This essay is not prepared for the elucidation of the structure of thought by Levinas, but for the verification of his propositions about moral, considering their persuasiveness and originality. We consider that his trial may involve the dissolution of the established concepts, and that it gives us some hints for analysing the serious mental problems in today\u27s society. His extreme theory concerning the moral of Autrui is most comprehensively developed in his dissertation "Totalité et Infini" (1961) and in his later period work "Autrement qu\u27être ou au-delà de l\u27essence" (1974). Therefore we will deal with and compare these books, and inquire the whereabouts of his thought of moral. For this purpose, we consider next points at issue: 1.On the problem of moral of Autrui 2.De-construction of the self 3.Retreat from moral 4.Moral guilty about the self 5.The whereabouts of the moral of Autru
