This volume is a collection of essays in appreciation, analysis and honour of Paul Ziff, one of the leading American philosophers of the post-World War II period. The essays address questions that loomed large in Ziff's own work. Essays by Zeno Vendler, Jay Rosenberg and Tom Patton address topics in philosophy of language: understanding, misunderstanding, rules, regularities, and proper names. Michael Resnik examines the nature of numbers, Rita Nolan addresses "mutant predicates", and Peter Alexander discusses microscopes and corpuscles. Douglas C. Long ruminates on Ziff's claim that machines can neither think nor feel. The essays of Dale Jamieson, Bill E. Lawson, Douglas Dempster, and Joseph Ullian address various questions in aesthetics: aesthetic appreciation and morality, expression, the scope of appreciation, and the aesthetics of sport. In the spirit of Ziff, Douglas Stalker criticizes some of the "mush" that looms large in our intellectual lives. The volume begins with a reminiscence by Paul Benacerraf, and ends with selections from an unpublished volume of plays by Paul Ziff. The volume should appeal to anyone whose work has been influenced by Ziff, or is interested in central philosophical problems concerning language, mind, and art.
