Efforts to make moral psychology a thoroughly empirical discipline have divided philosophers along methodological fault lines, isolating discussions that will profit more from intellectual exchange. This volume takes an even-handed approach, including essays from advocates of empirical ethics as well as those who are sceptical of some of its central claims.

Brian Leiter defends a set of radical ideas from Nietzsche: there is no objectively true morality, there is no free will, no one is ever morally responsible, and our conscious thoughts and reasoning play almost no significant role in our actions and how our lives unfold. He presents a new interpretation of main themes of Nietzsche's moral psychology, including his anti-realism about value (including epistemic value), his account of moral judgment and its relationship to the emotions, his conception of the will and agency, his scepticism about free will and moral responsibility, his epiphenomenalism about certain kinds of conscious mental states, and his views about the heritability of psychological traits. In combining exegesis with argument, Leiter engages the views of philosophers like Harry Frankfurt, T. M. Scanlon, and Gary Watson, and psychologists including Daniel Wegner, Benjamin Libet, and Stanley Milgram. Nietzsche emerges not simply as a museum piece from the history of ideas, but as a philosopher and psychologist who exceeds David Hume for insight into human nature and the human mind, repeatedly anticipates later developments in empirical psychology, and continues to offer sophisticated and unsettling challenges to much conventional wisdom in both philosophy and psychology.

Christine M. Korsgaard is one of today's leading moral philosophers: this volume collects ten influential papers by her on practical reason and moral psychology. Korsgaard draws on the work of important figures in the history of philosophy such as Plato, Aristotle, Kant, and Hume, showing how their ideas can inform the solution of contemporary and traditional philosophical problems, such as the foundations of morality and practical reason, the nature of agency, and the role of the emotions in action. In Part 1, The Principles of Practical Reason, Korsgaard defends the view that the principles of practical reason are constitutive principles of action. By governing our actions in accordance with Kant's categorical imperative and the principle of instrumental reason, she argues, we take control of our own movements and so render ourselves active, self-determining beings. She criticizes rival attempts to give a normative foundation to the principles of practical reason, challenges the claims of the principle of maximizing one's own interests to be a rational principle, and argues for some deep continuities between Plato's account of the connection between justice and agency and Kant's account of the connection between autonomy and agency. In Part II, Moral Virtue and Moral Psychology, Korsgaard takes up the question of the role of our more passive or receptive faculties--our emotions and responses --in constituting our agency. She sketches a reading of the Nicomachean Ethics, based on the idea that our emotions can serve as perceptions of good and evil, and argues that this view of the emotions is at the root of the apparent differences between Aristotle and Kant's accounts of morality. She argues that in fact, Aristotle and Kant share a distinctive view about the locus of moral value and the nature of human choice that, among other things, gives them account of what it means to act rationally that is superior to other accounts. In Part III, Other Reflections, Korsgaard takes up question how we come to view one another as moral agents in Hume's philosophy. She examines the possible clash between the agency of the state and that of the individual that led to Kant's paradoxical views about revolution. And finally, she discusses her methodology in an account of what it means to be a constructivist moral philosopher. The essays are united by an introduction in which Korsgaard explains their connections to each other and to her current work.

This book offers an analysis of experimental psychology that is embedded in a general understanding of human behavior. It provides methodological self-awareness for researchers who study and use the experimental method in psychology. The book critically reviews key research areas (e.g., rule-breaking, sense of agency, free choice, task switching, task sharing, and mind wandering), examining their scope, limits, ambiguities, and implicit theoretical commitments. Topics featured in this text include: Methods of critique in experimental research Goal hierarchies and organization of a task Rule-following and rule-breaking behavior Sense of agency Free-choice tasks Mind wandering Experimental Psychology and Human Agency will be of interest to researchers and undergraduate and graduate students in the fields of experimental psychology, cognitive psychology, theoretical psychology, and critical psychology, as well as various philosophical disciplines.

Many philosophers believe that normative ethics is in principle independent of psychology. By contrast, the authors of these essays explore the interconnections between psychology and moral theory. They investigate the psychological constraints on realizable ethical ideals and articulate the psychological assumptions behind traditional ethics. They also examine the ways in which the basic architecture of the mind, core emotions, patterns of individual development, social psychology, and the limits on human capacities for rational deliberation affect morality.

The concept of action that requires philosophical analysis is one that concerns behavior characteristically found in humans. In Action Reconceptualized: Human Agency and Its Sources, David K. Chan examines the sources of human agency that are proposed in causal theories of action—namely desire, intention, and trying—and distinguishes them from each other in terms of their roles in practical reasoning and motivation. He conceptualizes them in relation to each other in a way that is consistent and useful for answering a number of questions that are central to the philosophy of action. The action theory in this book addresses the need to understand human agency for its own sake, but it also serves another purpose. When the philosopher Elizabeth Anscombe stressed the need to do philosophy of action before doing ethical theory, what she meant was that moral philosophers should first work out a proper account of the relationship between the inner states of a person and the actions that she performs. This book provides such an account, and makes the case that it is desire, rather than intention, that is the basis for the ethical evaluation of an agent. Action Reconceptualized will be of particular interest to students and scholars doing research in action theory and ethics, as well as to those working outside of philosophy in psychology and cognitive science.
