Keio Correspondence Course: Masuki Tada, Problems in Political Philosophy Published in 1979, this book allows readers to explore the political philosophical issues and challenges of the time. It's a valuable resource for deepening understanding of the historical context and transitions. As it is from that era, the cover shows signs of aging and wear. There is some writing on the back cover, but the text itself is clean. Please review the photos and make your purchase with your understanding and agreement.
