Natural Law and Natural Rights is widely recognised as a seminal contribution to the philosophy of law, and an essential reference point for all students of the subject. This new edition includes a substantial postscript by the author responding to thirty years of comment, criticism, and further work in the field.

This book is a study of ancient views about "moral luck." It examines the fundamental ethical problem that many of the valued constituents of a well-lived life are vulnerable to factors outside a person's control, and asks how this affects our appraisal of persons and their lives. The Greeks made a profound contribution to these questions, yet neither the problems nor the Greek views of them have received the attention they deserve. This updated edition contains a new preface.

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

Value pluralism is the idea, most prominently endorsed by Isaiah Berlin, that fundamental human values are universal, plural, conflicting, and incommensurable with one another. Incommensurability is the key component of pluralism, undermining familiar monist philosophies such as utilitarianism. But if values are incommensurable, how do we decide between them when they conflict? George Crowder assesses a range of responses to this problem proposed by Berlin and developed by his successors. Three broad approaches are especially important: universalism, contextualism, and conceptualism. Crowder (...) argues that the conceptual approach is the most fruitful, yielding norms of value diversity, personal autonomy, and inclusive democracy. Historical context must also be taken into account. Together these approaches indicate a liberal politics of redistribution, multiculturalism, and constitutionalism, and a public policy in which basic values are carefully balanced. The Problem of Value Pluralism: Isaiah Berlin and Beyond is a uniquely comprehensive survey of the political theory of value pluralism and also an original contribution by a leading voice in the pluralist literature. Scholars and researchers interested in the work of Berlin, liberalism, value pluralism, and related ideas will find this a stimulating and valuable source. (shrink)

"Political Ideas in the Twentieth Century", Historical Inevitability", "Two Concepts of Liberty", "John Stuart Mill and the Ends of Life". These four essays deal with the various aspects of individual liberty, including the distinction between positive and negative liberty and the necessity of rejecting determinism if we wish to keep hold of the notions of human responsibility and freedom.

I argue that there are two distinct views called ‘value pluralism’ in contemporary axiology, but that these positions have not been properly distinguished. The first kind of pluralism, weak pluralism, is the view philosophers have in mind when they say that there are many things that are valuable. It is also the kind of pluralism that philosophers like Moore, Brentano and Chisholm were interested in. The second kind of pluralism, strong pluralism, is the view philosophers have in mind when they (...) say there are many values, or many kinds of value. It is also the kind of pluralism that philosophers like Stocker, Kekes and Nussbaum have advanced. I separate and elucidate these views, and show how the distinction between them affects the contemporary debate about value pluralism. (shrink)

How should we live? What do we owe to other people? In Goodness and Advice, the eminent philosopher Judith Jarvis Thomson explores how we should go about answering such fundamental questions. In doing so, she makes major advances in moral philosophy, pointing to some deep problems for influential moral theories and describing the structure of a new and much more promising theory. Thomson begins by lamenting the prevalence of the idea that there is an unbridgeable gap between fact and value--that (...) to say something is good, for example, is not to state a fact, but to do something more like expressing an attitude or feeling. She sets out to challenge this view, first by assessing the apparently powerful claims of Consequentialism. Thomson makes the striking argument that this familiar theory must ultimately fail because its basic requirement--that people should act to bring about the "most good"--is meaningless. It rests on an incoherent conception of goodness, and supplies, not mistaken advice, but no advice at all. Thomson then outlines the theory that she thinks we should opt for instead. This theory says that no acts are, simply, good: an act can at most be good in one or another way--as, for example, good for Smith or for Jones. What we ought to do is, most importantly, to avoid injustice; and whether an act is unjust is a function both of the rights of those affected, including the agent, and of how good or bad the act is for them. The book, which originated in the Tanner lectures that Thomson delivered at Princeton University's Center for Human Values in 1999, includes two chapters by Thomson ("Goodness" and "Advice"), provocative comments by four prominent scholars--Martha Nussbaum, Jerome Schneewind, Philip Fisher, and Barbara Herrnstein Smith--and replies by Thomson to those comments.

Plural and conflicting values are often held to be conceptually problematic, threatening the very possibility of ethics, or at least rational ethics. Rejecting this view, Stocker first demonstrates why it is so important to understand the issues raised by plural and conflicting values, focusing on Aristotle's treatment of them. He then shows that plurality and conflict are commonplace and generally unproblematic features of our everyday choice and action, and that they do allow for a sound and rational ethics.

A view with some considerable influence in current moral and political philosophy holds that there is a plurality of values, all of them fundamental and authoritative and yet, in some genuinely disconcerting way, in conflict . I shall call it ‘value-pluralism’.

A strong tradition in philosophy denies the possibility of moral dilemmas. Recently, several philosophers reversed this tradition. In this dissertation, I clarify some fundamental issues in this debate, argue for the possibility of moral dilemmas, and determine some implications of this possibility. ;In chapter I, I define moral dilemmas roughly as situations where an agent morally ought to adopt each of two alternatives but cannot adopt both. Moral dilemmas are resolvable if and only if one of the moral oughts overrides (...) the other. ;In chapter II, I criticize several opponents of moral dilemmas, including utilitarians, Kant, Aquinas, and Ross. My main criticism is that no opponent of moral dilemmas can adequately justify moral residue . ;Chapters III and IV concern the two main arguments against the possibility of moral dilemmas. First, the argument for 'ought' implies 'can' runs as follows. If the agent cannot adopt both, then it is not the case that the agent ought to adopt both. But the agent ought to adopt both, since the agent ought to adopt each . Thus, the defining judgements of a moral dilemma seem to imply a contradiction. In response, I argue that the relation between 'ought' and 'can' is not a logical implication but a conversational implicature. ;Chapter IV concerns the argument from 'ought' implies 'permitted': If the agent ought to adopt one alternative, then the agent is permitted to adopt that alternative, which means that it is not the case that the agent ought not to adopt that alternative. But the agent ought not to adopt that alternative, since the agent ought to adopt the other alternative and cannot adopt both. I respond that 'ought' does not logically imply but conversationally implicates 'permitted'. ;In chapter V, I argue that, despite recent claims, both moral realism and anti-realism are compatible with the possibility of moral dilemmas. Thus, there are several reasons to accept and no reasons to deny the possibility of moral dilemmas. (shrink)

Human agents act for reasons that contribute to their good. However, in our explanation of why agents act for reasons that depend on what they value, we encounter the problem of situations in which goods are neither better than others nor are of equal value. The incommensurability of value can then be seen to lead to an incommensurability of reasons for action. Examining rationalist and classical conceptions of human agency, Raz uses the presence of incommensurability to understand how this affects (...) the relation between reasons and the will, and its effects on our practical reasoning and deliberation. A proper understanding of human agency will take for granted that the goodness of options are incommensurate and that explanations concerning what we want cannot solely be accomplished in terms of reasons.

1. Presumably the point of, say, inculcating a moral outlook lies in a concern with how people live. It may seem that the very idea of a moral outlook makes room for, and requires, the existence of moral theory, conceived as a discipline which seeks to formulate acceptable principles of conduct. It is then natural to think of ethics as a branch of philosophy related to moral theory, so conceived, rather as the philosophy of science is related to science. On (...) this view, the primary topic of ethics is the concept of right conduct, and the nature and justification of principles of behaviour. If there is a place for an interest in the concept of virtue, it is a secondary place. Virtue is a disposition to behave rightly; the nature of virtue is explained, as it were, from the outside in.

Moral diversity is a fundamental reality of today’s world, but moral theorists have difficulty responding to it. Some take it as evidence for skepticism – the view that there are no moral truths. Others, associating moral reasoning with the search for overarching principles and unifying values, see it as the result of error. In the former case, moral reasoning is useless, since values express individual preferences; in the latter, our reasoning process is dramatically at odds with our lived experience. Moral (...) Reasoning in a Pluralistic World takes a different approach, proposing an alternative way of thinking about moral reasoning and progress by showing how diversity and disagreement are compatible with theorizing and justification. Patricia Marino demonstrates that, instead of being evidence for skepticism and error, moral disagreements often arise because we value things pluralistically. This means that although people share multiple values such as fairness, honesty, loyalty, and benevolence, we interpret and prioritize those values in various ways. Given this pluralistic evaluation process, preferences for unified single-principle theories are not justified. Focusing on finding moral compromises, prioritizing conflicting values, and judging consistently from one case to another, Marino elaborates her ideas in terms of real-life dilemmas, arguing that the moral complexity and conflict we so often encounter can be part of fruitful and logical moral reflection. Aiming to draw new connections and bridge the gap between theoretical ethics and applied ethics, Moral Reasoning in a Pluralistic World offers a sophisticated set of philosophical arguments on moral reasoning and pluralism with real world applications.

Several prominent ethical philosophers have attempted to demonstrate that there exist instances or types of value that are of crucial moral significance but which cannot legitimately be compared with one another. Bernard Williams and Michael Stocker, for example, argue that it can sometimes be rational to regret having chosen the all-things-considered better of two alternatives, and that this sense of regret entails that the goodness of the worse option is not made up for by and is therefore incommensurable with that (...) of the better. Joseph Raz and others have made similar points. In this paper, I propose a theory of value that is monistic in that it countenances just one sort of morally crucial value, but pluralistic in that several distinct properties bearer this value. I then explain how this view avoids incommensurable values without doing violence to the core intuitions that seemed to necessitate them, and how it fits into a larger conception of morality, right conduct, and moral psychology.

Many recent attacks on consequentialism and several defenses of pluralism have relied on arguments for the incommensurability of value. Such arguments have, generally, turned on empirical appeals to aspects of our everyday experience of value conflict. My intention, largely, is to bypass these arguments and turn instead to a discussion of the conceptual apparatus needed to make the claim that values are incommensurable. After delineating what it would mean for values to be incommensurable, I give an a priori argument that (...) such is impossible. It is widely accepted that value is conceptually tied to desire. I argue that, more specifically, it is proportional to merited desire strength. This connection gives one a metric of all value if there is any such thing. This metric entails that value is a complete ordering over all states of affairs, or, in other words, that value is commensurable. (shrink)

The incomparability of two items is thought to pose a problem for making justified choices and for consequentialist theories that rely on comparing states of the world to judge the goodness of a particular course of action. In response, it has been argued that items thought incomparable by one of the three standard relations, ‘better than’, ‘worse than’ and ‘equally good’, are instead comparable by some fourth relation, such as ‘roughly equal’ or ‘on a par’. Against such accounts, this article (...) argues that values in virtue of which comparisons are made can be ‘clumpy’ and that in comparisons involving clumpy values, we have no reason to accept ‘roughly equal’ or ‘on a par’ as distinct from ‘equally good’. The article supports the possibility of incomparability by arguing for an interpretation of incomparability as an instance of incommensurability. (shrink)

Value pluralists believe in multiple dimensions of value. What does betterness along a dimension have to do with being better overall? Any systematic answer begins with the Strong Pareto principle: one thing is overall better than another if it is better along one dimension and at least as good along all others. We defend Strong Pareto from recent counterexamples and use our discussion to develop a novel view of dimensions of value, one which puts Strong Pareto on firmer footing. We (...) conclude by defending Dimensionalism, the hypothesis that overall value relations are determined solely by how things compare along value dimensions. These are first steps towards a more systematic value pluralism. (shrink)

This essay discusses monism and pluralism about two related evaluative notions: welfare, or what makes people better off, and value simpliciter, or what makes the world better. These are stipulatively referred to as 'axiological value'. Axiological value property monists hold that one of these notions is reducible to the other (or else eliminable), while axiological value property pluralists deny this. Substantive monists about axiological value hold that there is just one basic kind of thing that makes our lives or the (...) world better, while substantive pluralists hold that there is more than one such thing. A more radical kind of pluralism holds that each of the plurality of good things is good in its own way, thus raising questions concerning value comparability and compensability. The essay elucidates these theories and discusses important arguments for and against them. (shrink)

In this book of essays, he argues that morality cannot be defined solely by rational and universal principles; instead, a major place must be found for changing and conflicting ideals, values peculiar to specific times and cultures.

When making moral judgments, people are typically guided by a plurality of moral rules. These rules owe their existence to human emotions but are not simply equivalent to those emotions. And people’s moral judgments ought to be guided by a plurality of emotion-based rules. The view just stated combines three positions on moral judgment: [1] moral sentimentalism, which holds that sentiments play an essential role in moral judgment,1 [2] descriptive moral pluralism, which holds that commonsense moral judgment is guided by (...) a plurality of moral rules2, and [3] prescriptive moral pluralism, which holds that moral judgment ought to be guided by a plurality of moral rules. In what follows, we will argue for all three positions. We will not present a comprehensive case for these positions nor address many of the arguments philosophers have developed against them. What we will try to show is that recent psychological work supports sentimentalist pluralism in both its descriptive and prescriptive forms. (shrink)

So-called theories of well-being (prudential value, welfare) are under-represented in discussions of well-being. I do four things in this article to redress this. First, I develop a new taxonomy of theories of well-being, one that divides theories in a more subtle and illuminating way. Second, I use this taxonomy to undermine some misconceptions that have made people reluctant to hold objective-list theories. Third, I provide a new objective-list theory and show that it captures a powerful motivation for the main competitor (...) theory of well-being (the desire-fulfilment theory). Fourth, I try to defuse the worry that objective-list theories are problematically arbitrary and show how the theory can and should be developed. (shrink)

Arguments for value incommensurability ultimately depend on a certain diagnosis of human motivation. Incommensurablists hold that each person's basic ends are not only irreducible but also incompatible with one another. It isn't merely that some goals can't, in fact, be jointly realized; values actually compete for influence. This account makes a mistake about the nature of human motivation. Each value underwrites a ceteris paribus evaluation. Such assessments are mutually compatible because the observation that there is something to be said for (...) an outcome from a particular perspective allows for any ultimate evaluation of that outcome; Values can be irreducible without thereby being incommensurable.

In this much-anticipated book, Jonathan Dancy offers the only available full-scale treatment of particularism in ethics, a view with which he has been associated for twenty years. Dancy now presents particularism as the view that the possibility of moral thought and judgement does not in any way depend on an adequate supply of principles. He grounds this claim on a form of reasons-holism, holding that what is a reason in one case need not be any reason in another, and maintaining (...) that moral reasons are no different in this respect from others. Ethics Without Principles offers detailed treatment and criticism of opposing positions of all sorts, with useful summaries. It also contains three chapters on the nature of what Dancy calls 'contributory' reasons, which, though the topic of much interest at the moment, are not often discussed in anything like the detail given here. And it offers a distinctive form of value-holism to go with the holism of reasons. As Dancy's definitive statement on particularism, the book will be required reading for all those working on moral philosophy and ethical theory. (shrink)

In other work I have argued that items can be on a par, where being on a par is a fourth, basic, sui generis value relation beyond the usual trichotomy of ‘better than’, ‘worse than’, and ‘equally good’. In this paper, I aim to marshal non-technical, intuitive arguments for this view. First, I try to cast doubt on the leading source of intuitive resistance to parity, the conviction that if two items are comparable, one must be better than the other, (...) worse than it, or they must be equally good. Second, I explain how parity can arise by appealing to an uncontroversial distinction between quantity and quality of value. I propose both sufficient conditions for parity and a nontechnical model of the notion. My overall aim is to bring into view a simple and intuitive picture of value – and more generally of normativity – in which parity plays a significant role. (shrink)

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers.".

"Out of the crooked timber of humanity, no straight thing was ever made."--Immanuel Kant Isaiah Berlin was one of the most important philosophers of the twentieth century--an activist of the intellect who marshaled vast erudition and eloquence in defense of the endangered values of individual liberty and moral and political pluralism. In the Crooked Timber of Humanity he exposes the links between the ideas of the past and the social and political cataclysms of our present century: between the Platonic belief (...) in absolute Truth and the lure of authoritarianism between the eighteenth-century reactionary ideologue Joseph de Maistre and twentieth-century fascism between the romanticism of Schiller and Byron and the militant--and sometimes genocidal--nationalism that convulses the modern world.

I consider the implications of incommensurability for the assumption, in rational choice theory, that a rational agent’s preferences are complete. I argue that, contrary to appearances, the completeness assumption and the existence of incommensurability are compatible. Indeed, reflection on incommensurability suggests that one’s preferences should be complete over even the incommensurable alternatives one faces.

This book attempts to answer two questions: Are alternatives for choice ever incomparable? and In what ways can items be compared? The arguments offered suggest that alternatives for choice no matter how different are never incomparable, and that the ways in which items can be compared are richer and more varied than commonly supposed.

This is the first book-length defence of liberalism on the basis of value pluralism, complementing and extending the work of Berlin and others.

Immanuel Kant's Groundwork of the Metaphysics of Morals ranks alongside Plato's Republic and Aristotle's Nicomachean Ethics as one of the most profound and influential works in moral philosophy ever written. In Kant's own words its aim is to search for and establish the supreme principle of morality, the categorical imperative. Kant argues that every human being is an end in himself or herself, never to be used as a means by others, and that moral obligation is an expression of the (...) human capacity for autonomy or self-government. This edition presents the acclaimed translation of the text by Mary Gregor, together with an introduction by Christine M. Korsgaard that examines and explains Kant's argument. (shrink)
