Does God's existence make a difference to how we explain morality? Mark C. Murphy critiques the two dominant theistic accounts of morality—natural law theory and divine command theory—and presents a novel third view. He argues that we can value natural facts about humans and their good, while keeping God at the centre of our moral explanations. The characteristic methodology of theistic ethics is to proceed by asking whether there are features of moral norms that can be adequately explained only if we hold that such norms have some sort of theistic foundation. But this methodology, fruitful as it has been, is one-sided. God and Moral Law proceeds not from the side of the moral norms, so to speak, but from the God side of things: what sort of explanatory relationship should we expect between God and moral norms given the existence of the God of orthodox theism? Mark C. Murphy asks whether the conception of God in orthodox theism as an absolutely perfect being militates in favour of a particular view of the explanation of morality by appeal to theistic facts. He puts this methodology to work and shows that, surprisingly, natural law theory and divine command theory fail to offer the sort of explanation of morality that we would expect given the existence of the God of orthodox theism. Drawing on the discussion of a structurally similar problem—that of the relationship between God and the laws of nature—Murphy articulates his new account of the relationship between God and morality, one in which facts about God and facts about nature cooperate in the explanation of moral law.

Powerful emotion and pursuit of self-interest have many times led people to break the law with the belief that they are doing so with sound moral reasons. This study is a comprehensive philosophical and legal analysis of the gray area in which the foundations of law and morality clash. In examining the extent of the obligations owed by citizens to their government, Greenawalt concentrates on the possible existence of a single source of obligation that reaches all citizens and all laws.

The essays of this volume examine natural moral law, different natural law theories, and the role that natural law can and should play in our contemporary society

This book examines the central questions of ethics through a study of the great ethical works of Western philosophy.

This Element defends a reading of Kant's formulas of the moral law in Groundwork of the Metaphysics of Morals. It disputes a long tradition concerning what the first formula (Universal Law/Law of Nature) attempts to do. The Element also expounds the Formulas of Humanity, Autonomy and the Realm of Ends, arguing that it is only the Formula of Humanity from which Kant derives general duties, and that it is only the third formula (Autonomy/Realm of Ends) that represents a complete and definitive statement of the moral principle as Kant derives it in the Groundwork. The Element also disputes the claim that the various formulas are 'equivalent', arguing that this claim is either false or else nonsensical because it is grounded on a false premise about what Kant thinks a moral principle is for.
