"Moral Responsibility and Ontology" is a comprehensive collection of revised papers that emerged from the international conference on this topic held at Utrecht University in June 1998. The book illuminates the complex and often ambiguous aspects of moral responsibility, particularly concerning the conditions under which individuals can be held accountable for their moral mistakes and omissions. It explores how moral responsibility can be distinguished from other forms of responsibility, such as causal responsibility. The discussions in this book provide valuable insights into the philosophical foundations of moral responsibility and its implications for individual and societal action. The contributions come from various authors who present different perspectives and interpretations on this important topic.
