This volume discusses Wittgenstein’s work, as well as his oeuvre in general, and its implications for the nature of reason. It investigates the nature of reason which has always been a topic at the very heart of Western philosophy. It analyzes how Wittgenstein raised crucial questions about the subject - most notably in his critique of Frazer’s Golden Bough, his discussions of various philosophical aspects of religion, and the famous ‘rule-following considerations’ from his Philosophical Investigations . The contributors include prominent Wittgenstein scholars from the UK and continental Europe including Hanjo Glock, Genia Schonbaumsfeld, Severin Schroeder Joachim Schulte and Crispin Wright. This book contains a translation of an important paper by the French Wittgenstein scholar Jacques Bouveresse, alongside six new papers by other contributors.
