Ingmar Persson offers an original view of the processes of human action: deliberating on the basis of reasons for and against actions, making a decision about what to do, and implementing the decision in action in a way that makes the action intentional.

What is it to want something? Or, as philosophers might ask, what is a desire? This book defends “desire-as-belief”, the view that desires are just a special subset of our beliefs: normative beliefs. This view entitles us to accept orthodox models of human motivation and rationality that explain those things with reference to desire, but nonetheless to also make room for our normative beliefs to play a role in those domains. And this view tells us to diverge from the orthodox (...) view on which desires themselves can never be right or wrong. Rather, according to desire-as-belief, our desires can themselves be assessed for their accuracy, and they are wrong when they misrepresent normative features of the world. Hume says that it is not contrary to reason to prefer the destruction of the whole world to the scratching of your finger, but he is wrong: it is foolish to prefer the destruction of the whole world to the scratching of your finger, and this is foolish because this preference misrepresents the relative worth of these things.

The burgeoning science of ethics has produced a trend toward pessimism. Ordinary moral thought and action, we’re told, are profoundly influenced by arbitrary factors and ultimately driven by unreasoned feelings. This book counters the current orthodoxy on its own terms by carefully engaging with the empirical literature. The resulting view, optimistic rationalism, shows the pervasive role played by reason, and ultimately defuses sweeping debunking arguments in ethics. The science does suggest that moral knowledge and virtue don’t come easily. However, despite (...) the heavy influence of automatic and unconscious processes that have been shaped by evolutionary pressures, we needn’t reject ordinary moral psychology as fundamentally flawed or in need of serious repair. Reason can be corrupted in ethics just as in other domains, but a special pessimism about morality in particular is unwarranted. Moral judgment and motivation are fundamentally rational enterprises not beholden to the passions. (shrink)

This book defends the Humean Theory of Motivation, according to which desire drives all action and practical reasoning. -/- Desire motivates us to pursue its object. It makes thoughts of its object pleasant. It focuses attention on its object. Its effects are amplified by vivid representations of its object. These aspects of desire explain why motivation usually accompanies moral belief, how intentions shape our plans, how we exercise willpower, what human selves are, how action can express emotion, why we procrastinate, (...) and how we daydream. The Humean Theory also suggests a new account of moral judgment that upholds objectivity while understanding moral concepts in terms of our feelings. (shrink)

Comparisons of rival explanations or theories often involve vague appeals to explanatory power. In this paper, we dissect this metaphor by distinguishing between different dimensions of the goodness of an explanation: non-sensitivity, cognitive salience, precision, factual accuracy and degree of integration. These dimensions are partially independent and often come into conflict. Our main contribution is to go beyond simple stipulation or description by explicating why these factors are taken to be explanatory virtues. We accomplish this by using the contrastive-counterfactual approach (...) to explanation and the view of understanding as an inferential ability. By combining these perspectives, we show how the explanatory power of an explanation in a given dimension can be assessed by showing the range of answers it provides to what-if-things-had-been-different questions and the theoretical and pragmatic importance of these questions. Our account also explains intuitions linking explanation to unification or to exhibition of a mechanism. (shrink)

This essay defends a strong version of the Humean theory of motivation on which desire is necessary both for motivation and for reasoning that changes our desires. Those who hold that moral judgments are beliefs with intrinsic motivational force need to oppose this view, and many of them have proposed counterexamples to it. Using a novel account of desire, this essay handles the proposed counterexamples in a way that shows the superiority of the Humean theory. The essay addresses the classic (...) objection that the Humean theory cannot explain the feeling of obligation, Stephen Darwall's example of motivationally potent reasoning that is not based on preexisting desires, Thomas Scanlon's criticism that the Humean theory fails to account for the structure and phenomenology of deliberation, and the phenomenon of akrasia as discussed by John Searle. In each case a Humean account explains the data at least as thoroughly as opposing views can, while fitting within a simpler total account of how we deliberate and act. (shrink)

Reasons without Rationalism has two related parts, devoted to action theory and ethics, respectively. In the second part, I argue for a close connection between reasons for action and virtues of character. This connection is mediated by the idea of good practical thought and the disposition to engage in it. The argument relies on the following principle, which is intended as common ground: " Reasons: The fact that p is a reason for A to ϕ just in case A has (...) a collection of psychological states, C, such that the disposition to be moved to ϕ by C-and-the-belief-that- p is a good disposition of practical thought, and C contains no false beliefs."In effect, reasons are premises for episodes of sound practical thinking whose other conditions already ….

What is the relation between a reason and an action when the reason explains the action by giving the agent's reason for doing what he did? We may call such explanations rationalizations, and say that the reason rationalizes the action. In this paper I want to defend the ancient - and common-sense - position that rationalization is a species of ordinary causal explanation. The defense no doubt requires some redeployment, but not more or less complete abandonment of the position, as (...) urged by many recent writers. (shrink)

Human agency has four irreducibly different dimensions -- psychological, ethical, intellectual, and physical -- which the traditional idea of a will tended to conflate. Twentieth-century philosophers criticized the idea that acts are caused by 'willing' or 'volition', but the study of human action continued to be governed by a tendency to equate these dimensions of agency, or to reduce one to another. Cutting across the branches of philosophy, from logic and epistemology to ethics and jurisprudence, Action, Knowledge, and Will defends (...) comprehensive theories of action and knowledge, and shows how thinking about agency in four dimensions deepens our understanding of human conduct and its causes.

Introduction -- Instrumental rationality -- Social order -- Deontic constraint -- Intentional states -- Preference noncognitivism -- A naturalistic perspective -- Transcendental necessity -- Weakness of will -- Normative ethics.

Understanding human beings and their distinctive rational and volitional capacities requires a clear account of such things as reasons, desires, emotions, and motives, and how they combine to produce and explain human behaviour. Maria Alvarez presents a fresh and incisive study of these concepts, centred on reasons and their role in human agency.

Humeans hold that actions are movements of an agent's body that are suitably caused by a desire that things be a certain way and a belief on the agent's behalf that something she can just do, namely perform a movement of her body of the kind to be explained, has some suitable chance of making things that way (Davidson 1963). Movements of the body that are caused in some other way aren't actions, but are rather things that merely happen to (...) agents. (shrink)

To desire something is a condition familiar to everyone. It is uncontroversial that desiring has something to do with motivation, something to do with pleasure, and something to do with reward. Call these "the three faces of desire." The standard philosophical theory at present holds that the motivational face of desire presents its unique essence--to desire a state of affairs is to be disposed to act so as to bring it about. A familiar but less standard account holds the hedonic (...) face of desire to reveal to true nature of desire. In this view, to desire something is to tend to pleasure if it seems that the desired state of affairs has been achieved, or displeasure if it seems otherwise, thus tying desire to feelings instead of actions. In Three Faces of Desire, Schroeder goes beyond actions and feelings to advance a novel and controversial theory of desire that puts the focus on desire's neglected face, reward. Informed by contemporary science as much as by the philosophical tradition, Three Faces of Desire discusses recent scientific discoveries that tell us much about the way that actions and feelings are produced in the brain. In particular, recent experiments reveal that a distinctive system is responsible for promoting action, on the one hand, and causing feelings of pleasure and displeasure, on the other. This system, the brain's reward system, is the causal origin of both action and feeling, and is the key to understanding the nature of desire. (shrink)
