The Routledge Handbook of Practical Reason is an outstanding reference source to this exciting and distinctive subject area. Comprising over thirty chapters by a team of international contributors the handbook provides a comprehensive overview of the field covering questions such as:

• What is the nature of the reasons for which we act and what is the nature of the faculty of practical reason?
• What are normative reasons for action?
• What is practical irrationality and what are the requirements, permissions, and powers that explain what it is to be practically rational and irrational?
• What is the relationship between ethics and the philosophy of practical reason?

This handbook will be essential reading for philosophy students and researchers in metaethics, philosophy of action, action theory, ethics and history of philosophy.
