The essays in this volume, written by eight of the world's leading legal theorists and philosophers, began life as papers presented at seminars (held in Canberra and New York) devoted to the ideas of Tony Honor, who is one of the most important legal thinkers of his generation. The focus is on issues dealt with in Honor's recent book, ""Responsibility and Fault"" (1999), including determinism and luck, causation, outcome responsibility, and the morality of strict liability. Honor's book, and these essays, discuss fundamental questions about the relationship between moral and legal responsibility. They explore the contribution that the philosophy of action and of mind can make to understanding the law.
