Wittgenstein's complex and demanding work challenges much that is taken for granted in philosophical thinking as well as in the theorizing of art, theology, science, and culture. Each essay in this collection explores a key concept involved in Wittgenstein's thinking, relating it to his understanding of philosophy and outlining the arguments and explaining the implications of each concept. Concepts covered include grammar, meaning and meaning-blindness, language-games and private language, family resemblances, psychologism, rule-following, teaching and learning, avowals, Moore's Paradox, aspect seeing, the meter-stick, and criteria. Students new to Wittgenstein and readers interested in developing their understanding of specific aspects of his philosophical work will find this book very welcome. Contributors include Avner Baz, James Conant, David Finkelstein, Craig Fox, Heather Gert, Arata Hamawaki, Lars Hertzberg, Phil Hutchinson, Kelly Dean Jolley, Roderick T. Long, Eric Loomis, Rupert Read, and Avrum Stroll.
