Keith Donnellan of UCLA is one of the founding fathers of contemporary philosophy of language, along with David Kaplan and Saul Kripke. Donnellan was and is an extremely creative thinker whose insights reached into metaphysics, action theory, the history of philosophy, and of course the philosophy of mind and language. This volume collects the best critical essays on Donnellan's forty-year body of work. The pieces by such noted philosophers as Tyler Burge, David Kaplan, and John Perry, discuss Donnellan's various insights particularly offering new readings of his views on language and mind.
