Ralph Wedgwood gives a general account of the concept of rationality. The Value of Rationality is designed as the first instalment of a trilogy - to be followed by accounts of the requirements of rationality that apply specifically to beliefs and choices. The central claim of the book is that rationality is a normative concept. This claim is defended against some recent objections. Normative concepts are to be explained in terms of values (not in terms of 'ought' or reasons). Rationality is itself a value: rational thinking is in a certain way better than irrational thinking. Specifically, rationality is an internalist concept: what it is rational for you to think now depends solely on what is now present in your mind. Nonetheless, rationality has an external goal - the goal of thinking correctly, or getting things right in one's thinking. The connection between thinking rationally and thinking correctly is probabilistic: if your thinking is irrational, that is in effect bad news about your thinking's degree of correctness. This account of rationality explains how we should set about giving a theory of what it is for beliefs and choices to be rational. Wedgwood thus unifies practical and theoretical rationality, and reveals the connections between formal accounts of rationality (such as those of formal epistemologists and decision theorists) and the more metaethics-inspired recent discussions of the normativity of rationality. He does so partly by drawing on recent work in the semantics of normative and modal terms (including deontic modals like 'ought').

This book focuses on the standards of philosophical rationality, corresponding to a philosophy that aspires to be more than the wisdom that stems from and addresses everyday human needs. It is a search for standards that would, as it were, show the way to philosophical wisdom for anyone who is willing and able to assess it. One of the problems is that people have had a different understanding of the basic concept of rationality, which is the rationale. (Series: Development in Humanities - Vol. 1)

Reason and rationality represent crucial elements of the self-image of human beings and have unquestionably been among the most debated issues in Western philosophy, dating from ancient Greece, through the Middle Ages, and to the present day. Many words and thoughts have already been spent trying to define the nature and standards of reason and rationality, what they could or ought to be, and under what conditions something can be said to be rational. This volume focuses instead on the relationships of reason and rationality to some relevant specific topics, i.e., science, knowledge, gender, politics, ethics, religion, aesthetics, language, logic, and metaphysics, trying to uncover and clarify both the connections and differences in their various characterisations and uses.

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.

Problems of Rationality is the eagerly awaited fourth volume of Donald Davidson's philosophical writings. From the 1960s until his death in August 2003 Davidson was perhaps the most influential figure in English-language philosophy, and his work has had a profound effect upon the discipline. His unified theory of the interpretation of thought, meaning, and action holds that rationality is a necessary condition for both mind and interpretation. Davidson here develops this theory to illuminate value judgements and how we understand them; to investigate what the conditions are for attributing mental states to an object or creature; and to grapple with the problems presented by thoughts and actions which seem to be irrational. Anyone working on knowledge, mind, and language will find these essays essential reading.

Rationality and Religious Commitment shows how religious commitment can be rational and describes the place of faith in the postmodern world. It portrays religious commitment as far more than accepting doctrines—it is viewed as a kind of life, not just as an embrace of tenets. Faith is conceived as a unique attitude. It is irreducible to belief but closely connected with both belief and conduct, and intimately related to life's moral, political, and aesthetic dimensions. Part One presents an account of rationality as a status attainable by mature religious people—even those with a strongly scientific habit of mind. Part Two describes what it means to have faith, how faith is connected with attitudes, emotions, and conduct, and how religious experience may support it. Part Three turns to religious commitment and moral obligation and to the relation between religion and politics. It shows how ethics and religion can be mutually supportive even though ethics provides standards of conduct independently of theology. It also depicts the integrated life possible for the religiously committed—a life with rewarding interactions between faith and reason, religion and science, and the aesthetic and the spiritual. The book concludes with two major accounts. One explains how moral wrongs and natural disasters are possible under God conceived as having the knowledge, power, and goodness that make such evils so difficult to understand. The other account explores the nature of persons, human and divine, and yields a conception that can sustain a rational theistic worldview even in the contemporary scientific age.

In a series of essays nine philosophers and two psychologists address three main themes: the status of norms of rationality; the precise form taken by them; and the role of norms in belief and actions.
