It is well-known that Nishida Kitaro asserted the motive of philosophy must be the grief of life. In
early literature, the grief of life has been often dealt with in terms of the Nishida's life. It is true that his
life was not a little unhappy and grief was his motive of philosophy. However, the grief of life is important not only in his life, but also in the system of his philosophy. Even when the grief of life was dealt with in terms of the system of philosophy in early literature, it was treated in the context of emotion.
But it is more essential in the context of selfrealization. In short, he thinks that self is realized as place of nothingness and as the unique person in the grief of life. He finds a sort of contradiction in selfrealization. Or rather, he thinks of self as the contradiction itself. He finds two aspects in the contradiction. One is that self is intuited when it gets lost and subsumes objects .. That means the fundamental acquisition of the body and the self-realization as subsuming place of nothingness. The other aspect of the contradiction is the coincidence of the realization of the eternal death and that of the uniqueness of self. In both aspects, the negation of the grief plays essential roles.
