Saul Kripke's Wittgenstein on Rules and Private Language is one of the most celebrated and important books in philosophy of language and mind of the past forty years. It generated an avalanche of responses from the moment it was published and has revolutionized the way in which we think about meaning, intentionality, and the work of Ludwig Wittgenstein. It introduced a series of questions that had never been raised before concerning, most prominently, the normativity of meaning and the prospects for a reductionist account of meaning. This volume of new essays reassesses the continuing influence of Kripke's book and demonstrates that many of the issues first raised by Kripke, both exegetical and philosophical, remain as thought-provoking and as relevant as they were when he first introduced them.
