Drawing and building on the existing literature, this Element explores the interesting and challenging philosophical terrain where issues regarding cooperation, commitment, and control intersect. Section 1 discusses interpersonal and intrapersonal Prisoner's Dilemma situations, and the possibility of a set of unrestrained choices adding up in a way that is problematic relative to the concerns of the choosers involved. Section 2 focuses on the role of precommitment devices in rational choice. Section 3 considers the role of resoluteness in rational choice and action. And Section 4 delves into some related complications concerning the nature of actions and the nature of intentions.
A distinguished group of philosophers, decision theorists, and psychologists offer new interdisciplinary perspectives on the rationality of self-control.
Suppose that you prefer A to B, B to C, and C to A. Your preferences violate Expected Utility Theory by being cyclic. Money-pump arguments offer a way to show that such violations are irrational. Suppose that you start with A. Then you should be willing to trade A for C and then C for B. But then, once you have B, you are offered a trade back to A for a small cost. Since you prefer A to B, you pay the small sum to trade from B to A. But now you have been turned into a money pump. You are back to the alternative you started with but with less money. This Element shows how each of the axioms of Expected Utility Theory can be defended by money-pump arguments of this kind. This title is also available as Open Access on Cambridge Core.
For most of its history, decision theory has investigated the rational choices of humans under the assumption of static preferences. Human preferences, however, change. In recent years, decision theory has increasingly acknowledged the reality of preference change throughout life. This Element provides an accessible introduction and new contributions to the debates on preference change. It is divided into three chapters. In the first chapter, the authors discuss what preference change is and whether we can integrate it into decision theory. In the second chapter, they present models of preference change, including a novel proposal of their own. In the third and final chapter, they discuss how we can rationally choose a course of action when our preferences might change. Both the transformative experience literature and recent work on choosing for changing selves are discussed.
Beliefs come in degrees, and we often represent those degrees with numbers. We might say, for example, that we are 90% confident in the truth of some scientific hypothesis, or only 30% confident in the success of some risky endeavour. But what do these numbers mean? What, in other words, is the underlying psychological reality to which the numbers correspond? And what constitutes a meaningful difference between numerically distinct representations of belief? In this Element, we discuss the main approaches to the measurement of belief. These fall into two broad categories-epistemic and decision-theoretic-with divergent foundations in the theory of measurement. Epistemic approaches explain the measurement of belief by appeal to relations between belief states themselves, whereas decision-theoretic approaches appeal to relations between beliefs and desires in the production of choice and preferences.
Why do people persist in commitments that threaten their happiness, security, and comfort? Why do some of our most central, identity-defining commitments seem to resist the effects of reasoning and critical reflection? Drawing on real-life examples, empirical psychology, and philosophical reflection, Paul Katsafanas argues that these commitments involve an ethical stance called devotion, which plays a pervasive--but often hidden--role in human life. Devotion typically involves sacralizing certain values, goals, or relationships. To sacralize a value is to treat it as inviolable (trade-offs with ordinary values are forbidden), incontestable (even contemplating such trade-offs is prohibited), and dialectically invulnerable (no rational considerations can disrupt the agent's commitment to the value). Philosophy of Devotion offers a detailed philosophical account and defense of these features. Devotion and the sacralization of values can be reasonable; indeed, a life involving meaningful, sustained commitment depends on these stances. Without devotion, we risk an existential condition that Katsafanas describes as normative dissipation, in which all of our commitments become etiolated. Yet devotion can easily go wrong, deforming into the individual and group fanaticism that have become pervasive features of modern social life. Katsafanas provides an alternative to fanaticism, investigating the way in which we can express non-pathological forms of devotion. We can be devoted through affirmation and through what Katsafanas calls the deepening move, which treats the agent's central commitments as systematically inchoate. Each of these stances enables a wholehearted form of devotion that nevertheless preserves flexibility and openness, avoiding the dangers of fanaticism on the one hand and normative dissipation on the other. But this is inevitably a fragile and precarious achievement: affirmation can slide into a focus on rejecting what isn't affirmed, and the deepening move can ossify into rigidity. Only the perpetual quest to maintain a form of existential flexibility, which may require oscillation between affirmation and deepening, can stave off these dangers
Within traditional decision theory, common decision principles -- e.g. the principle to maximize utility -- generally invoke idealization; they govern ideal agents in ideal circumstances. In Realistic Decision Theory, Paul Weirch adds practicality to decision theory by formulating principles applying to nonideal agents in nonideal circumstances, such as real people coping with complex decisions. Bridging the gap between normative demands and psychological resources, Realistic Decision Theory is essential reading for theorists seeking precise normative decision principles that acknowledge the limits and difficulties of human decision-making.
The connection between economics and ethics is as old as economics itself, and central to both disciplines. The essays included in the present volume provide an analysis of the connections between ethics and economics as viewed from several different - oft
For several decades, David Gauthier has been one of the leading philosophers working on practical rationality and deliberation. This book presents a selection of Gauthier's writings on these topics, all but two of which were written after Morals by Agreement (OUP, 1986). They represent Gauthier's most important contributions to the theory of practical reason, moving some distance from the view a first presented in "Reason and Maximization" and developed in a much-reprinted chapter of Morals by Agreement. These essays challenge common misconceptions of Gauthier's revisionist conception of practical rationality, and provide important insights with implications for economic theory.
These essays focus on questions that arise when morality is considered from the perspective of rational choice and evolution. It links questions like ""is it rational to be moral?"" to the evolution of co-operation, and uses models from game theory, evolutionary biology and cognitive science.
