Abstract
The problem of the logic of reality has been a key metaphycial issue since the time of ancient Greek. On the basis of Nishida's idea of ＂Absolute Contradictory Selfidentity＂, which is the final formulation of his logic of basho, the main purpose of this paper is, on the one hand, to explore Nishida's possible contribution to our understanding of reality, and on the other hand, to focus on the logical structure and metaphysical implication of the idea. The paper is divided into five sections: After a brief introduction of the theme of the paper (section one), by using the ideas collected from Nishida's ＂the World as Dialectical Universal＂ (1934), this paper aims at clarifying the meaning of ＂Medium M＂ (section two). In order to highlight the necessity of his logic of nothingness, Nishida's criticism on Plato's and Aristotle's logic is to be discussed. Following from the aforementioned discussion, the paper tries to explicate the logical structure of Nishida's ＂Absolute Contradictory Selfidentity＂ (section three). By using Nishida's idea of ＂Inverse Correspondence＂ as a clue, this paper then turns to focus on Nishida's ＂Discontinuous Continuity＂ and demonstrate its concrete meaning using (section four). Finally, according to Nishida's later concept of ＂Discontinuous Continuity＂, this paper reflects upon the restriction of traditional logic, and clarify some main concepts in Nishida's early ＂Zen no kenkyo＂ (section five).
