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.

How do we formulate a coherent moral code in a world without religion? How can we show natural ideas like 'moral relativism' and 'egoism' to be irrational? Moreover, how can we create a genuinely scientific and rational theory of morality which, so far, has evaded academics? Rational Morality sets out to answer these questions by presenting a new form of ethics for the Brian Cox and Richard Dawkins generation. In this passionate, thought-provoking and often radical thesis, Robert Johnson presents both a refreshing theory of morality based on science and a guide to the practical consequences of what a truly rational concept of morality involves.

A basic dilemma confronting today’s manager is how to be both profitable and moral. Making profits through immoral means—such as deceiving investors or customers—is unsustainable. Likewise, remaining moral while losing money will cause a business to fail. According to conventional morality, either a business manager maximizes profits and necessarily compromises on ethics, or necessarily sacrifices profits in order to be moral. Woiceshyn explains why this is a false dichotomy and offers rational egoism as an alternative moral code to businesspeople who want to maximize profits ethically. Through logical argument and various examples, this book shows how to apply principles such as rationality, productiveness, honesty, justice, and pride for long-term self-interest.

First published in 1990. The aim of this thesis is to show that the way to understand the central claims of Kant’s ethics is to accept the idea that morality is a distinctive form of rationality; that the moral "ought" belongs to a system of imperatives based in practical reason; and that moral judgment, therefore, is a species of rational assessment of agents’ actions. It argues, in effect, that you cannot understand Kant’s views about morality if you read him with Humean assumptions about rationality. This title will be of interest to students of philosophy.

The humanity formulation of Kant's Categorical Imperative demands that we treat humanity as an end in itself. Because this principle resonates with currently influential ideals of human rights and dignity, contemporary readers often find it compelling, even if the rest of Kant's moral philosophy leaves them cold. Moreover, some prominent specialists in Kant's ethics have recently turned to the humanity formulation as the most theoretically central and promising principle of Kant'sethics. Nevertheless, it has received less attention than many other aspects of Kant's ethics. Richard Dean offers the most sustained and systematic examination of the humanity formulation to date. He presents an original analysis of what it means to treat humanity as an end in itself, and examinesthe implications both for Kant scholarship and for practical guidance on specific moral issues.

'The Rational and the Moral Order' is a significant book providing a comprehensive theory of morality. The opening chapter is simply marvellous. Baier provides a cogent response to Hume's conundrums on practical reasoning: logical entailment, he argues, is not the correct model of the relation between reasons and that for which they are reasons. Indeed, the giving of reasons is, in part, a social enterprise, and there is no necessary connection between rationality and self-interest. Just as the giving of reasons is a social enterprise taught to succeeding generations, so too is the moral enterprise, for a moral order is a social order of some sort. It is a social order that encourages a critical stance toward, and permits the correction of, its mores. Moral precepts can be sound or unsound, and yet can be relative to a moral order. In the concluding chapter Baier shows how his theoretical framework can be used to confront some of the moral problems people face, problems which have also exercised contemporary philosophers. Though there are many philosophers who believe that killing is worse than letting anyone die, there are few that defend the view other than by raw intuition. Baier deploys the resources of his theory of morality in support of this widely shared but poorly defended viewpoints. "Along the way, Baier deals with virtually all the problems that have taxed moral philosophers for a very long time -- rationality, responsibility, morality's relation to law, the good life, prisoner's dilemma, moral motivation, and others. The Rational and the Moral Order is careful, insightful, and convincing." --Theodore M. Benditt, University of Alabama

Originally published in 1988, this landmark study develops its own positive account of the nature and foundations of moral judgement, while at the same time serving as a guide to the range of views on the matter which have been given in modern western philosophy. The book addresses itself to two main questions: Can moral judgements be true or false in that fundamental sense in which a true proposition is one which describes things as they really are? Are rational methods available in ethics which can be expected to produce convergence on shared moral views on the part of those who use them intelligently?
