(Used) The Logic of Philosophical Understanding (Contemporary Logic Series) Waseda University Press By Naruo Nagai Price: 1400 yen The cover and sides (especially the top edge) have scratches and stains. I didn't find any other scratches or stains, but this is a personal inspection, so there may be oversights. As this is a used book, please refrain from purchasing if you are concerned about minor details or if you are looking for a perfect copy. I will take measures to protect against rain and will ship anonymously via Rakuraku Mercari. Thank you for your understanding.
