Reading Hobbes in light of both the history of ethics and the conceptual apparatus developed in recent work on normativity, this book challenges received interpretations of Hobbes and his historical significance. Arash Abizadeh uncovers the fundamental distinction underwriting Hobbes's ethics: between prudential reasons of the good, articulated via natural laws prescribing the means of self-preservation, and reasons of the right or justice, comprising contractual obligations for which we are accountable to others. He shows how Hobbes's distinction marks a watershed in the transition from the ancient Greek to the modern conception of ethics, and demonstrates the relevance of Hobbes's thought to current debates about normativity, reasons, and responsibility. His book will interest Hobbes scholars, historians of ethics, moral philosophers, and political theorists.

‘Path-breaking and tremendously insightful, Hobbes and the Two Faces of Ethics reveals how Hobbes revolutionized ethical theory by sharply distinguishing reasons of the right from reasons of the good. Bold yet rigorous, wide-ranging and meticulous, this superb monograph is destined to become a landmark study of Hobbes's philosophy. Required reading for anyone interested in Hobbes and the development of modern ethics and meta-ethics.'

‘This reading is powerful, and convincing … the book must be judged a success, and an impressive one - saying something new about Hobbes is not easy, and saying it this convincingly is even more exceptional … rewarding book.’
