Writing clearly and avoiding jargon, Dilman investigates Wittgenstein's understanding of the relation between language and reality - i.e. between "the realities" we refer to, speak about and try to understand. Dilman discusses this topic in depth and at the same time covers a broad ground. He appreciates the following different aspects: philosophical skepticism about the existence of the various categories of things and our knowledge of them, about the reality of the logic of the language we speak and of the forms of our reasoning, philosophy's contribution to our understanding of the world and of ourselves, and the contributions of the arts to such an understanding.
