Under the theme of “Philosophy and Art”, my task is to consider the relationship between philosophy and the logic of architecture. From the viewpoint of philosophers, Aristotle and Plato, regarded architecture in Greek as representing technology which could control all types of technologies, and architect as a man with both theory and practice. In Idealism in Germany, architecture as art and architectural space became subject of philosophy. In phenomenology, especially by M. Heidegger, architecture became considered from human and living. As to architectural theory, Keiichi Morita (1895-1983)is the pioneer, introducing Vitruvius, who established the logic of architecture in B.C. 30, insisting that architect should learn all of the studies. Morita achieved his original logic of architecture based on studies of Vitruvius and other Western aesthetics. He also referred to architectural space. In his theory, architecture Should represent architecture itself, and should be considered in total. His followers developed various theories referring to aesthetics, space, They seem to trend opposite to Morita’s theory, but the principle of their architectural theory has been the same as that of Morita’s based on something occurring among human and architecture. Reviewing the logic of architecture and comparing it with Nishida’s theory, they seem to resemble each other, particularly considering the original point of these theories.
