What role does reason play in our actions? How do we know whether what we do is right? Can practical reasoning guide ethical judgment?

Practical Reasoning and Ethical Decision presents an account of practical reasoning as a process that can explain action, connect reasoning with intention, justify practical judgments, and provide a basis for ethical decisions.

The first part of the book is a detailed critical overview of the influential theories of practical reasoning found in Aristotle, Hume, and Kant. The second part examines practical reasoning in the light of important topics in moral psychology-weakness of will, self-deception, rationalization, and others. In the third part, Audi describes the role of moral principles in practical reasoning and clarifies the way practical reasoning underlies ethical decisions. He formulates a comprehensive set of concrete ethical principles, explains how they apply to reasoning about what to do, and shows how practical reasoning guides moral conduct.

Practical Reasoning and Ethical Decision provides the most comprehensive account of the topic in the current literature and is essential reading for anyone interested in the role of reason in ethics or the nature of human action.
