This volume comprises a lively and thorough discussion between philosophers and Tyler Burge about Burge's recent, and already widely accepted, position in the theory of meaning, mind and knowledge. This position is embodied by an externalist theory of meaning and an anti-individualist theory of mind and approach to self-knowledge. The authors of the 11 papers expound their versions of this position and go on to critique Burge's version. Together with Burge's replies, this volume offers a major contribution to contemporary philosophy.
