For over thirty years, Robert Audi has produced important work in ethics, epistemology, and the theory of action. This volume features thirteen new critical essays on Audi by a distinguished group of authors: Fred Adams, William Alston, Laurence BonJour, Roger Crisp, Elizabeth Fricker, Bernard Gert, Thomas Hurka, Hugh McCann, Al Mele, Walter Sinnott-Armstrong, Raimo Tuomela, Candace Vogler, and Timothy Williamson. Audi's introductory essay provides a thematic overview interconnecting his views in ethics, epistemology, and philosophy of action. The volume concludes with his comprehensive response essay that yields an illuminating dialog with all his critics and often extends his previous work. "Mark Timmons, John Greco, and Alfred R. Mele have put together an excellent collection of essays on the work of Robert Audi.... It ranges over a broad set of topics and contains much high quality philosophical work from a distinguished set of contributors."--Scott Sehon, Notre Dame Philosophical Reviews Newly written critical essays by leading philosophers in ethics, epistemology, and philosophy of action on Robert Audi Mark Timmons is at Arizona State University.
