The Moral Rules

In this final revision of the classic work, the author has produced the fullest and most sophisticated account of this influential theoretical model. Here, he makes clear that morality is an informal system that does not provide unique answers to every moral question but does always limit the range of morally acceptable options, and so explains why some moral disagreements cannot be resolved. The importance placed on the moral ideals also makes clear that the moral rules are only one part of the moral system. A chapter that is devoted to justifying violations of the rules illustrates how the moral rules are embedded in the system and cannot be adequately understood independently of it. The chapter on reasons includes a new account of what makes one reason better than another and elucidates the complex hybrid nature of rationality.

Exploring the relationship between consequentialist theory and moral rules, this book focuses mainly on rule consequentialism or on the distinction between act and rule versions of consequentialism.

Moral systems, like normative systems more broadly, involve complex mental representations. Rational Rules proposes that moral learning can be understood in terms of general-purpose rational learning procedures. Nichols argues that statistical learning can help answer a wide range of questions about moral thought: Why do people think that rules apply to actions rather than consequences? Why do people expect new rules to be focused on actions rather than consequences? How do people come to believe a principle of liberty, according to which whatever is not expressly prohibited is permitted? How do people decide that some normative claims hold universally while others hold only relative to some group? The resulting account has both empiricist and rationalist features: since the learning procedures are domain-general, the result is an empiricist theory of a key part of moral development, and since the learning procedures are forms of rational inference, the account entails that crucial parts of our moral system enjoy rational credentials. Moral rules can also be rational in the sense that they can be effective for achieving our ends, given our ecological settings. Rational Rules argues that at least some central components of our moral systems are indeed ecologically rational: they are good at helping us attain common goals. Nichols argues that the account might be extended to capture moral motivation as a special case of a much more general phenomenon of normative motivation. On this view, a basic form of rule representation brings motivation along automatically, and so part of the explanation for why we follow moral rules is that we are built to follow rules quite generally.

Distinguished philosopher Bernard Gert presents a clear and concise introduction to what he calls "common morality"--the moral system that most thoughtful people implicitly use when making everyday, common sense moral decisions and judgments. Common Morality is useful in that--while not resolving every disagreement on controversial issues--it is able to distinguish between acceptable and unacceptable answers to moral problems.

This volume is a revised, enlarged, and broadened version of Gert's classic 1970 book, The Moral Rules. Advocating an approach he terms "morality as impartial rationality," Gert here presents a full discussion of his moral theory, adding a wealth of new illuminating detail to his analysis of the concepts--rationality/irrationality, good/evil, and impartiality--by which he defines morality. He constructs a "moral system" that includes rules prohibiting the kinds of actions that cause evil, procedures for determining when violation of the rules is permitted, and ideals which encourage actions that prevent or relieve suffering. To be valid, Gert argues, any such system must be "a public system that applies to all rational persons." The book concludes with a discussion of medical ethics, demonstrating the link between moral theory and its application to real moral problems.
