This anthology identifies four central themes in Wittgenstein's Investigations-reference and meaning, rules and their application, the interiority of mind and the alleged uses of private languages, and necessity and grammar-and provides important recent essays that explore these themes in lucid detail. Intended for both the novice and experienced reader of Wittgenstein's classic work, this book includes important notes and references to help make his problems and arguments more accessible.
