About the book
This is the follow-up to Derek Parfit's 1984 book 'Reasons and Persons'. Parfit presents a powerful new treatment of reasons, rationality, and normativity, and a critical examination of three systematic moral theories - Kant's ethics, contractualism, and consequentialism - leading to his own ground-breaking synthetic conclusion.
