This book takes us on a fascinating journey through the world of thought of Miki Kiyoshi, one of Japan’s pre-eminent philosophers before the Pacific War, and thus makes us discover the man behind the philosopher. His collaboration with government think-tanks in the late 1930s has made him highly controversial in historiographical debates. His death in prison, six weeks after Japan's defeat, hastened the lifting of pre-war restrictions on civil rights in Japan. He was a prolific, diverse and original thinker, revered by the Japanese as a plain-speaking, deeply humanistic philosopher who connected with the real lives of the people. As a translator, editor and journalist he intoduced many works of western European literature and philosophy into Japan.
