In fifteen essays-one new, two newly revised and expanded, three with new postscripts-Kendall L. Walton wrestles with philosophical issues concerning music, metaphor, empathy, existence, fiction, and expressiveness in the arts. These subjects are intertwined in striking and surprising ways. By exploring connections among them, appealing sometimes to notions of imagining oneself in shoes different from one's own, Walton creates a wide-ranging mosaic of innovative insights.

In addition to thin concepts like the good, the bad and the ugly, our evaluative thought and talk appeals to thick concepts like the lewd and the rude, the selfish and the cruel, the courageous and the kind - concepts that somehow combine evaluation and non-evaluative description. Thick concepts are almost universally assumed to be inherently evaluative in content, and many philosophers claimed them to have deep and distinctive significance in ethics and metaethics. In this first book-length treatment of thick concepts, Pekka Vayrynen argues that all this is mistaken. Through detailed attention to the language of thick concepts, he defends a novel theory on which the relationship between thick words and evaluation is best explained by general conversational and pragmatic norms. Drawing on general principles in philosophy of language, he argues that many prominent features of thick words and concepts can be explained by general factors that have nothing in particular to do with being evaluative. If evaluation is not essential to the sort of thinking we do with thick concepts, claims for the deep and distinctive significance of the thick are undermined. The Lewd, the Rude and the Nasty is a fresh and innovative treatment of an important topic in moral philosophy and sets a new agenda for future work. It will be essential reading to anyone interested in the analysis and the broader philosophical significance of evaluative and normative language. "Vayrynen presents an extremely well researched, highly innovative, and yet very careful and highly polished treatment of an extremely hot area in philosophy. The book is tightly argued but engagingly written. I would hold it up as a model philosophy monograph. There is no doubt in my mind whatsoever that this book will be widely influential and admired. Indeed, it could easily become a classic." - Brad Hooker, University of Reading "For the past few decades thick concepts have received much attention in metaethical discussions, but Vayrynen's book is the first comprehensive treatment of the subject. Vayrynen skillfully uses tools from philosophy of language in order to sharpen and advance the discussion of thick concepts. The book will be essential reading not only to anyone interested in the specific topic of thick concepts but also to anyone who is concerned with the analysis of normative language generally. It is a very good paradigm of linguistically informed metaethics." - Matti Eklund, Cornell University

After centuries of neglect, the ethics of food are back with a vengeance. Justice for food workers and small farmers has joined the rising tide of concern over the impact of industrial agriculture on food animals and the broader environment, all while a global epidemic of obesity-related diseases threatens to overwhelm modern health systems. An emerging worldwide social movement has turned to local and organic foods, and struggles to exploit widespread concern over the next wave of genetic engineering or nanotechnologies applied to food. Paul B. Thompson's book applies the rigor of philosophy to key topics in the first comprehensive study explore interconnections hidden deep within this welter of issues. Bringing more than thirty years of experience working closely with farmers, agricultural researchers and food system activists to the topic, he explores the eclipse of food ethics during the rise of nutritional science, and examines the reasons for its sudden re-emergence in the era of diet-based disease. Thompson discusses social injustice in the food systems of developed economies and shows how we have missed the key insights for understanding food ethics in the developing world. His discussions of animal production and the environmental impact of agriculture breaks new ground where most philosophers would least expect it. By emphasizing the integration of these issues, Thompson not only brings a comprehensive philosophical approach to moral issues in the production, processing, distribution, and consumption of food - he introduces a fresh way to think about practical ethics that will have implications in other areas of applied philosophy.

Indian thought is well known for diverse philosophical and contemplative excursions into the nature of selfhood. Led by Buddhists and the yoga traditions of Hinduism and Jainism, Indian thinkers have engaged in a rigorous analysis and reconceptualization of our common notion of self. Less understood is the way in which such theories of self intersect with issues involving agency and free will; yet such intersections are profoundly important, as all major schools of Indian thought recognize that moral goodness and religious fulfillment depend on the proper understanding of personal agency. Moreover, their individual conceptions of agency and freedom are typically nodes by which an entire school's epistemological, ethical, and metaphysical perspectives come together as a systematic whole. Free Will, Agency, and Selfhood in Indian Philosophy explores the contours of this issue, from the perspectives of the major schools of Indian thought. With new essays by leading specialists in each field, this volume provides rigorous analysis of the network of issues surrounding agency and freedom as developed within Indian thought.

Kant's discussion of the relations between cognition and self-consciousness lie at the heart of the Critique of Pure Reason, in the celebrated transcendental deduction. Although this section of Kant's masterpiece is widely believed to contain important insights into cognition and self-consciousness, it has long been viewed as unusually obscure. Many philosophers have tried to avoid the transcendental psychology that Kant employed. By contrast, Patricia Kitcher follows Kant's careful delineation of the necessary conditions for knowledge and his intricate argument that knowledge requires self-consciousness. She argues that far from being an exercise in armchair psychology, the thesis that thinkers must be aware of the connections among their mental states offers an astute analysis of the requirements of rational thought.
The book opens by situating Kant's theories in the then contemporary debates about "apperception," personal identity and the relations between object cognition and self-consciousness. After laying out Kant's argument that the distinctive kind of knowledge that humans have requires a unified self- consciousness, Kitcher considers the implications of his theory for current problems in the philosophy of mind. If Kant is right that rational cognition requires acts of thought that are at least implicitly conscious, then theories of consciousness face a second "hard problem" beyond the familiar difficulties with the qualities of sensations. How is conscious reasoning to be understood? Kitcher shows that current accounts of the self-ascription of belief have great trouble in explaining the case where subjects know their reasons for the belief. She presents a "new" Kantian approach to handling this problem. In this way, the book reveals Kant as a thinker of great relevance to contemporary philosophy, one whose allegedly obscure achievements provide solutions to problems that are still with us.

In the last decade, science in the United States has become increasingly politicized, as government officials have been accused of manipulating, distorting, subverting, and censoring science for ideological purposes. Political gamesmanship has played a major role in many different areas of science, including the debate over global climate change, embryonic stem cell research, government funding of research, the FDA's approval process, military intelligence related to Iraq, research with human subjects, and the teaching of evolution in public schools.
In Playing Politics with Science, David B. Resnik explores the philosophical, political, and ethical issues related to the politicalization of science and develops a conceptual framework for thinking about government restrictions on scientific practice. Resnik argues that the public has a right and a duty to oversee scientific research to protect important social values and hold scientists accountable for their actions, but that inappropriate government control over science can erode the integrity and trustworthiness of research, hamper scientific creativity and innovation, undermine the fairness and effectiveness of government and policies informed by science, discourage talented researchers from working for the government, and violate the freedom of scientists.
Resnik also makes policy recommendations for protecting science from politicalization, and maintains that scientific autonomy and government control must be properly balanced so that restrictions on science can benefit society without undermining scientific research, education, and expert advice.

Terry Pinkard draws on Hegel's central works as well as his lectures on aesthetics, the history of philosophy, and the philosophy of history in this deeply informed and original exploration of Hegel's naturalism. As Pinkard explains, Hegel's version of naturalism was in fact drawn from Aristotelian naturalism: Hegel fused Aristotle's conception of nature with his insistence that the origin and development of philosophy has empirical physics as its presupposition. As a result, Hegel found that, although modern nature must be understood as a whole to be non-purposive, there is nonetheless a place for Aristotelian purposiveness within such nature. Such a naturalism provides the framework for explaining how we are both natural organisms and also practically minded (self-determining, rationally responsive, reason-giving) beings. In arguing for this point, Hegel shows that the kind of self-division which is characteristic of human agency also provides human agents with an updated version of an Aristotelian final end of life. Pinkard treats this conception of the final end of "being at one with oneself" in two parts. The first part focuses on Hegel's account of agency in naturalist terms and how it is that agency requires such a self-division, while the second part explores how Hegel thinks a historical narration is essential for understanding what this kind of self-division has come to require of itself. In making his case, Hegel argues that both the antinomies of philosophical thought and the essential fragmentation of modern life are all not to be understood as overcome in a higher order unity in the "State." On the contrary, Hegel demonstrates that modern institutions do not resolve such tensions any more than a comprehensive philosophical account can resolve them theoretically. The job of modern practices and institutions (and at a reflective level the task of modern philosophy) is to help us understand and live with precisely the unresolvability of these oppositions. Therefore, Pinkard explains, Hegel is not the totality theorist he has been taken to be, nor is he an "identity thinker," a la Adorno. He is an anti-totality thinker.

Political theory, from antiquity to the present, has been divided over the relationship between the requirements of justice and the limitations of persons and institutions to meet those requirements. Some theorists hold that a theory of justice should be utopian or idealistic-that the derivation of the correct principles of justice should not take into account human and institutional limitations. Others insist on a realist or non-utopian view, according to which feasibility-facts about what is possible given human and institutional limitations-is a constraint on principles of justice. In recent years, the relationship between the ideal and the real has become the subject of renewed scholarly interest. This anthology aims to represent the contemporary state of this classic debate. By and large, contributors to the volume deny that the choice between realism and idealism is binary. Rather, there is a continuum between realism and idealism that locates these extremes of each view at opposite poles. The contributors, therefore, tend to occupy middle positions, only leaning in the ideal or non-ideal direction. Together, their contributions not only represent a wide array of attractive positions in the new literature on the topic, but also collectively advance how we understand the difference between idealism and realism itself.

Cognitive psychology has matured and flourished in the last half-century, as new theories, research tools, and theoretical frameworks have allowed cognitive psychologists and researchers to explore a broad array of topics. In the same vein, the depth of understanding and the methodological and theoretical sophistication have also grown in wonderful ways. Given the expanse of the field, an up-to-date and inclusive resource such as this handbook is needed for aspiring generalists who wish to read the book cover to cover, and for the many readers who are simply curious to know the current happenings in other cognition laboratories. Guided by this need, this volume's 64 chapters cover all aspects of cognition, spanning perceptual issues, attention, memory, knowledge representation, language, emotional influences, judgment, problem solving, and the study of individual differences in cognition. Additional chapters turn to the control of complex actions and the social, cultural, and developmental context of cognition. The authors include a mix of well-established influential figures and younger colleagues in order to gain an understanding of the field's forward trajectory. The volume also includes a mix of "tutorial" chapters and chapters that powerfully represent a particular research team's point of view.

Ernest Lepore and Kirk Ludwig examine the foundations and applications of Davidson's influential program of truth-theoretic semantics for natural languages. The program uses an axiomatic truth theory for a language, which meets certain constraints, to serve the goals of a compositional meaning theory. Lepore and Ludwig explain and clarify the motivations for the approach, and then consider how to apply the framework to a range of important natural language constructions, including quantifiers, proper names, indexicals, simple and complex demonstratives, quotation, adjectives and adverbs, the simple and perfect tenses, temporal adverbials and temporal quantifiers, tense in sentential complement clauses, attitude and indirect discourse reports, and the problem of interrogative and imperative sentences. They not only discuss Davidson's own contributions to these subjects but consider criticisms, developments, and alternatives as well. They conclude with a discussion of logical form in natural language in light of the approach, the role of the concept of truth in the program, and Davidson's view of it. Anyone working on meaning will find this book invaluable.

Ex nihilo nihil fit. Philosophy, especially great philosophy, does not appear out of the blue. In the current volume, a team of top scholars-both up-and-coming and established-attempts to trace the philosophical development of one of the greatest philosophers of all time. Featuring twenty new essays and an introduction, it is the first attempt of its kind in English and its appearance coincides with the recent surge of interest in Spinoza in Anglo-American philosophy. Spinoza's fame-or notoriety-is due primarily to his posthumously published magnum opus, the Ethics, and, to a lesser extent, to the 1670 Theological-Political Treatise. Few readers take the time to study his early works carefully. If they do, they are likely to encounter some surprising claims, which often diverge from, or even utterly contradict, the doctrines of the Ethics. Consider just a few of these assertions: that God acts from absolute freedom of will, that God is a whole, that there are no modes in God, that extension is divisible and hence cannot be an attribute of God, and that the intellectual and corporeal substances are modes in relation to God. Yet, though these claims reveal some tension between the early works and the Ethics, there is also a clear continuity between them. Spinoza wrote the Ethics over a long period of time, which spanned most of his philosophical career. The dates of the early drafts of the Ethics seem to overlap with the assumed dates of the composition of the Treatise on the Emendation of the Intellect and the Short Treatise on God, Man, and His Well Being and precede the publication of Spinoza's 1663 book on Descartes' Principles of Philosophy. For this reason, a study of Spinoza's early works (and correspondence) can illuminate the nature of the problems Spinoza addresses in the Ethics, insofar as the views expressed in the early works help us reconstruct the development and genealogy of the Ethics. Indeed, if we keep in mind the common dictum "nothing comes from nothing "-which Spinoza frequently cites and appeals to-it is clear that great works like the Ethics do not appear ex nihilo. In light of the preeminence and majesty of the Ethics, it is difficult to study the early works without having the Ethics in sight. Still, we would venture to say that the value of Spinoza's early works is not at all limited to their being stations on the road leading to the Ethics. A teleological attitude of such a sort would celebrate the works of the "mature Spinoza " at the expense of the early works. However, we have no reason to assume that on all issues the views of the Ethics are better argued, developed, and motivated than those of the early works. In other words, we should keep our minds open to the possibility that on some issues the early works might contain better analysis and argumentation than the Ethics.

The authors of this book argue that there is a great divide between species that makes extrapolation of biochemical research from one group to another utterly invalid. In their previous book, "Sacred Cows and Golden Geese: The Human Cost of Experiments on Animals", the Greeks showed how an amorphous but insidious network of drug manufacturers, researchers dependent on government grants to earn their living, even cage-manufacurers - among others benefiting from "white-coat welfare" - have perpetuated animal research in spite of its total unpredictability when applied to humans. (Cancer in mice, for example, has long been cured. Chimps live long and relatively healthy lives with AIDS. There is no animal form of Alzheimer's disease.) In doing so, the Greeks aimed to blow the lid off the "specious science" we have been culturally conditioned to accept. Taking these revelations one step further, this book uses accessible language to provide the scientific underpinning for the Greeks' philosophy of "do no harm to any animal, human or not," by examining paediatrics, diseases of the brain, new surgical techniques, in vitro research, the Human Genome and Proteome Projects, an array of scien

This new book by Michael Slote argues that Western philosophy on the whole has overemphasized rational control and autonomy at the expense of the important countervailing value and virtue of receptivity. Recently the ideas of caring and empathy have received a great deal of philosophical and public attention, but both these notions rest on the deeper and broader value of receptivity, and in From Enlightenment to Receptivity, Slote seeks to show that we need to focus more on receptivity if we are to attain a more balanced sense and understanding of what is important to us.
Beginning with a critique of Enlightenment thinking that calls into question its denial of any central role to considerations of emotion and empathy, he goes on to show how a greater emphasis on these factors and on the receptivity that underlies them can give us a more realistic, balanced, and sensitive understanding of our core ethical and epistemological values. This means rejecting post-modernism's blanket rejection of reason and of compelling real values and recognizing, rather, that receptivity should play a major role in how we lead our lives as individuals, in how we relate to nature, in how we acquire knowledge about the world, and in how we relate morally and politically with others.

While gender and race often are considered socially constructed, this book argues that they are physiologically constituted through the biopsychosocial effects of sexism and racism. This means that to be fully successful, critical philosophy of race and feminist philosophy need to examine not only the financial, legal, political and other forms of racist and sexism oppression, but also their physiological operations. Examining a complex tangle of affects, emotions, knowledge, and privilege, The Physiology of Sexist and Racist Oppression develops an understanding of the human body whose unconscious habits are biological. On this account, affect and emotion are thoroughly somatic, not something "mental " or extra-biological layered on top of the body. They also are interpersonal, social, and can be transactionally transmitted between people. Ranging from the stomach and the gut to the hips and the heart, from autoimmune diseases to epigenetic markers, Sullivan demonstrates the gastrointestinal effects of sexual abuse that disproportionately affect women, often manifesting as IBS, Crohn's disease, or similar functional disorders. She also explores the transgenerational effects of racism via epigenetic changes in African American women, who experience much higher pre-term birth rates than white women do, and she reveals the unjust benefits for heart health experienced by white people as a result of their racial privilege. Finally, developing the notion of a physiological therapy that doesn't prioritize bringing unconscious habits to conscious awareness, Sullivan closes with a double-barreled approach for both working for institutional change and transforming biologically unconscious habits. The Physiology of Sexist and Racist Oppression skillfully combines feminist and critical philosophy of race with the biological and health sciences. The result is a critical physiology of race and gender that offers new strategies for fighting male and white privilege.

A unifying theme of Loeb's work is epistemological - that Descartes and Hume advance theories of knowledge that rely on a substantial 'naturalistic' component, adopting one or another member of a cluster of psychological properties of beliefs as the goal of inquiry and the standard for assessing belief-forming mechanisms. Thus Loeb shows a surprising affinity between the epistemologies of the two figures -- surprising because they are often thought of as polar opposites in this respect.
Descartes and Hume are unique in that their philosophical texts are accessible beyond just a narrow audience in the history of philosophy; their ideas continue to be a vital part of the field at large. This volume will thus appeal to advanced students and scholars not just in the history of early modern philosophy but in epistemology and other core areas of the discipline.

After 9/11/2001, gendered narratives of humiliation and revenge proliferated in the U.S. national imaginary. How is it that gender, which we commonly take to be a structure at the heart of individual identity, is also at stake in the life of the nation? What do we learn about gender when we pay attention to how it moves and circulates between the lived experience of the subject and the aspirations of the nation in war? What is the relation between national sovereignty and sovereign masculinity? Through examining practices of torture, extra-judicial assassination, and first person accounts of soldiers on the ground, Bonnie Mann develops a new theory of gender. It is neither a natural essence nor merely a social construct. Gender is first and foremost an operation of justification which binds the lived existence of the individual subject to the aspirations of the regime. Inspired by a reexamination of the work of Simone de Beauvoir, the author exposes how sovereign masculinity hinges on the nation's ability to tap into and mobilize the structure of self-justification at the heart of masculine identity. At the national level, shame is repeatedly converted to power in the War on Terror through hyperbolic displays of agency including massive aerial bombardment and practices of torture. This is why, as Mann demonstrates, the phenomenon of gender itself demands a four-dimensional analysis that moves from the phenomenological level of lived experience, through the collective life of a people expressed in the social imaginary and the operations of language, to the material relations that prevail in our times.

In the 1950s, John Reber convinced many Californians that the best way to solve the state's water shortage problem was to dam up the San Francisco Bay. Against massive political pressure, Reber's opponents persuaded lawmakers that doing so would lead to disaster. They did this not by empirical measurement alone, but also through the construction of a model. Simulation and Similarity explains why this was a good strategy while simultaneously providing an account of modeling and idealization in modern scientific practice. Michael Weisberg focuses on concrete, mathematical, and computational models in his consideration of the nature of models, the practice of modeling, and nature of the relationship between models and real-world phenomena.
In addition to a careful analysis of physical, computational, and mathematical models, Simulation and Similarity offers a novel account of the model/world relationship. Breaking with the dominant tradition, which favors the analysis of this relation through logical notions such as isomorphism, Weisberg instead presents a similarity-based account called weighted feature matching. This account is developed with an eye to understanding how modeling is actually practiced. Consequently, it takes into account the ways in which scientists' theoretical goals shape both the applications and the analyses of their models.

The aim of this volume is to open up reflection on the nature of vulnerability, the responsibilities owed to the vulnerable, who bears these responsibilities, and how they are best fulfilled. In canvassing responses to these questions, the contributors engage with a range of ethical traditions and with issues in contemporary political philosophy and bioethics. Some essays in the volume explore the connections between vulnerability, autonomy, dignity, and justice. Other essays engage with a feminist ethics of care to articulate the relationship between vulnerability, dependence, and care. These theoretical approaches are complemented by detailed examination of vulnerability in specific contexts, including disability; responsibilities to children; intergenerational justice; and care of the elderly. The essays thus address fundamental questions concerning our moral duties to each other as individuals and as citizens. Contributing significantly to the development of an ethics of vulnerability, this volume opens up promising avenues for future research in feminist philosophy, moral and political philosophy, and bioethics.

The first single-volume anthology of Brecht's writings on both art and politics This volume contains new translations to extend our image of one of the twentieth century's most entertaining and thought provoking writers on culture, aesthetics and politics. Here are a cross-section of Brecht's wide-ranging thoughts which offer us an extraordinary window onto the concerns of a modern world in four decades of economic and political disorder. The book is designed to give wider access to the experience of a dynamic intellect, radically engaged with social, political and cultural processes. Each section begins with a short essay by the editors introducing and summarising Brecht's thought in the relevant year.

The diversity of Nietzsche's books, and the sheer range of his philosophical interests, have posed daunting challenges to his interpreters. This Oxford Handbook addresses this multiplicity by devoting each of its 32 essays to a focused topic, picked out by the book's systematic plan. The aim is to treat each topic at the best current level of philosophical scholarship on Nietzsche. The first group of papers treat selected biographical issues: his family relations, his relations to women, and his ill health and eventual insanity. In Part 2 the papers treat Nietzsche in historical context: his relations back to other philosophers-the Greeks, Kant, and Schopenhauer-and to the cultural movement of Romanticism, as well as his own later influence in an unlikely place, on analytic philosophy. The papers in Part 3 treat a variety of Nietzsche's works, from early to late and in styles ranging from the 'aphoristic' The Gay Science and Beyond Good and Evil through the poetic-mythic Thus Spoke Zarathustra to the florid autobiography Ecce Homo. This focus on individual works, their internal unity, and the way issues are handled within them, is an important complement to the final three groups of papers, which divide up Nietzsche's philosophical thought topically. The papers in Part 4 treat issues in Nietzsche's value theory, ranging from his metaethical views as to what values are, to his own values of freedom and the overman, to his insistence on 'order of rank', and his social-political views. The fifth group of papers treat Nietzsche's epistemology and metaphysics, including such well-known ideas as his perspectivism, his INSERT: Included in Starkmann 40% promotion, September-October 2014 being, and his thought of eternal recurrence. Finally, Part 6 treats another famous idea-the will to power-as well as two linked ideas that he uses will to power to explain, the drives, and life. This Handbook will be a key resource for all scholars and advanced students who work on Nietzsche.

When and why is it right to kill? When and why is it wrong? Torbjoern Tannsjoe examines three theories on the ethics of killing in this book: deontology, a libertarian moral rights theory, and utilitarianism. The implications of each theory are worked out for different kinds of killing: trolley-cases, murder, capital punishment, suicide, assisted death, abortion, killing in war, and the killing of animals. These implications are confronted with our intuitions in relation to them, and our moral intuitions are examined in turn. Only those intuitions that survive an understanding of how we have come to hold them are seen as 'considered' intuitions. The idea is that the theory that can best explain the content of our considered intuitions gains inductive support from them. We must transcend our narrow cultural horizons and avoid certain cognitive mistakes in order to hold considered intuitions. In this volume, suitable for courses in ethics and applied ethics, Tannsjoe argues that in the final analysis utilitarianism can best account for, and explain, our considered intuitions about all these kinds of killing.

HarperCollins is proud to present its incredible range of best-loved, essential classics. Our life is what our thoughts make it The extraordinary writings of Marcus Aurelius (AD 121-180), the only Roman emperor to have also been a stoic philosopher, have for centuries been praised for their wisdom, insight and guidance by leaders and great thinkers alike. Never intended for publication, Meditations are the personal notes born from a man who studied his unique position of power as emperor while trying to uphold inner balance in the chaotic world around him. Boldly challenging many of our biggest questions, Aurelius wrestles with the divided self, considering the complexities of human nature, rationality and moral virtue, affirming its place as one of the most timeless, significant works of philosophy to date.

Presents cutting edge theory about the consequences of social movements and protest while asking what kind of trade-offs protest movements face in trying to change the world around them. Many scholars have tried to figure out why some social movements have an impact and others do not. By looking inside movements at their component parts and recurrent strategic interactions, the authors of Gains and Losses show that movements usually produce a variety of effects, including recurring packages of gains and losses. They ask what kinds of trade-offs and dilemmas these packages reflect by looking at six empirical cases from around the world: Seattle's conflict over the $15 an hour minimum wage; the establishment of participatory budgeting in New York City; a democratic insurgency inside New York City's Transport Workers' Union; a communist party's struggle to gain votes and also protect citizen housing in Graz, Austria; the internal movement tensions that led to Hong Kong's umbrella occupation; and Russia's electoral reform movement embodied in Alexei Navalny. They not only examine the diverse players in these cases involved in politics and protest, but also the many strategic arenas in which they maneuver. While each of these movements made some remarkable gains, this book shows how many also suffered losses, especially in the longer run.

Philip Pettit has drawn together here a series of interconnected essays on three subjects to which he has made notable contributions. The first part of the book discusses the rule-following character of thought. The second considers how choice can be responsive to different sorts of factors, while still being under the control of thought and the reasons that thought marshals. The third examines the implications of this view of choice and rationality for the normative regulation of social behaviour.
