The purpose of this paper is to explore the differences in contemporary abtract art between the conception of the Oriental Art and the Western one. Because of the interaction of these two, the nature of art conception has been modified. First of all, we inquired into how the Western Art extended to abtract one in its historical progress. The core of all the progress is mainly a tendency of purism. On the other hand, we examined the source of conception of the Oriental Art. The conception originated in Zhuangzi, one has been progressed when Buddhism has been introduced to China form India. To the faculty of making use of the artistic form, it is clear that Zhuangzi is different from the Zen Sect as to the use of representation. Thirdly, we arrived at the conclusion that the oriental artistic conception is different from the western one by the dialogue between Hisamatsu and Heidegger about Zen Art. The Oriental Zen Art attaches importance to the recurrence of interior source. The nature of the Zen Art is this source. The nature of the Western Art is mould, so that it is the art of creating, "be". Contemporary art is just an inevitable consequence of purism of abstracting "be".
