In this Beginner's Guide, Peter Hacker introduces the later philosophy of Wittgenstein in a lively and engaging combination of lectures and dialogues that presupposes no philosophical knowledge. He examines such topics as the nature of language and linguistic meaning, the analysis of necessity and its roots in convention, the relation of thought and language, the nature of the mind and its relation to behaviour, self-consciousness, and knowledge of other minds. This unique form of introduction will capture the interest of all readers with an enquiring mind.
