Abstract
In this paper, we are concerned with the linguistic concept of Hiromatsu Wataru, the Japanese Marxism philosopher. Tracing the development of his thought, we can find the linguistic concept embedded in his philosophical concepts. His article on the linguistic concept concentrated in the 1960s, when he started to publish academic articles, and he continued referring to it. In the 1980s, structuralism and post-structuralism originated in France was prevalent in Japan. Respecting such situation, Hiromatsu published some articles on semiotics. Moreover, two conversations with Keizaburo Maruyama, an eminent Saussure scholar, were held. In this paper, tracing Hiromatsu’s theory from the perspective of linguistics, we try to illustrate that linguistics has been his main theme. The results from this paper indicate that intersubjectivity, his main philosophical concept, is inseparable from the linguistic concept, and this cogitation dates back to his graduation thesis on epistemology.
