The postwar “Overcoming Modernism” theory was initiated from around 1956 and emerged fully through the post-ideological declaration of Takeuchi Yoshimi’s Overcoming Modernism announced in 1959. On the other hand, discussion in Takeuchi’s Overcoming Modernism, which is a part of Lectures on the Modern History of Japanese Thoughts (1959), is not clear by itself. In order to understand its meaning and significance, we should approach it from the aspect of continuity with referring to the “Overcoming Modernism” theory in the 1950s. Only then, we can see clearly what is meant by the postwar opening of the “Overcoming Modernism” theory. Takeuchi’s Overcoming Modernism mentions the literary circle’s discourses of “Overcoming Modernism” discourses, but considering the way raising questions and the contents of discussion, it is only the philosophical circle’s discourses that were accommodated implicitly as essential references. Takeuchi’s Overcoming Modernism, which restructured discourses in the 1950s, assumed that ‘nationalism’ is a precondition for thoughts applicable to realities and suggested the condition in round-table conference “Overcoming Modernism”. However, his suggestion did not include specific universal values required in order to distinguish the materialization of ‘“Overcoming Modernism” ─ nationalism ─ postwar theory’ from ‘the revival of round-table conference “Overcoming Modernism”.’ For this reason, moreover, the task left by him provided new direction ‘the development of postwar thoughts’ in the postwar “Overcoming Modernism” theory.
