    Why naturalism?
    Ethical Theory and Moral Practice 6 (2): 179-200. 2003.
    My goal in this paper is to explain what ethical naturalism is, to locate the pivotal issue between naturalists and non-naturalists, and to motivate taking naturalism seriously. I do not aim to establish the truth of naturalism nor to answer the various familiar objections to it. But I do aim to motivate naturalism sufficiently that the attempt to deal with the objections will seem worthwhile. I propose that naturalism is best understood as the view that the moral properties are natural in the s…Read more

    Against Internalism About Reasons—Gert’s Rational Options (review)
    Philosophy and Phenomenological Research 62 (2): 455-8211. 2001.
    The contemporary debate about the relation between reasons and motivation is partly driven by the problem of explaining the “normativity” of reasons. Reasons are “prescriptive”. They direct us how to act. They are “apt” to guide our choices. Moreover, reasons are “action guiding”. Insofar as we are rational, we let them guide our choices, for we accept their instructions. These formulations are metaphorical, however, and the problem is to explain precisely what they mean. One strategy for explai…Read more

    The Ring of Gyges: Overridingness and the Unity of Reason
    Social Philosophy and Policy 14 (1): 86-106. 1997.
    Does morality override self-interest? Or does self-interest override morality? These questions become important in situations where there is conflict between the overall verdicts of morality and self-interest, situations where morality on balance requires an action that is contrary to our self-interest, or where considerations of self-interest on balance call for an action that is forbidden by morality. In situations of this kind, we want to know what we ought simpliciter to do. If one of these …Read more

    Moral Obligation and Moral Motivation
    Canadian Journal of Philosophy, Supplement 21 (sup1). 1995.
    'Internalism’ in ethics is a cluster of views according to which there is an ‘internal’ connection between moral obligations and either motivations or reasons to act morally; ‘externalism’ says that such connections are contingent. So described, the dispute between internalism and externalism may seem a technical debate of minor interest. However, the issues that motivate it include deep problems about moral truth, realism, normativity, and objectivity. Indeed, I think that some philosophers vie…Read more

    The Idea of a Legitimate State
    Philosophy and Public Affairs 28 (1): 3-45. 1999.
    A legitimate state would have a right to rule. The problem is to understand, first, precisely what this right amounts to, and second, under what conditions a state would have it. According to the traditional account, the legitimacy of a state is to be explained in terms of its subjects’ obligation to obey the law. I argue that this account is inadequate. I propose that the legitimacy of a state would consist in its having a bundle of rights of various kinds, which I specify. Among other things, …Read more

    This chapter begins by explaining the distinction between meta-ethics and normative ethics. It then introduces the main issues in the two fields and provides a critical overview of the chapters in the volume. In meta-ethics, it focuses on explaining the different kinds of moral realism and anti-realism, including the divine command theory, naturalism, non-naturalism, relativism, nihilism, and non-cognitivism. Quasi-realism illustrates how the distinction between anti-realism and realism can beco…Read more

    In his recent book, David Estlund argues that democratic states can be legitimate while epistocracy cannot be legitimate. His argument rests on his “Qualified Acceptability Requirement,” according to which a state is legitimate only if its coercive enforcement of law can be justified on a basis that is acceptable to all possible qualified points of view. This principle may seem to express a Rawlsian liberal ideal, but I claim it is undermined by Rawlsian arguments. I argue that Estlund’s positio…Read more

    This comment addresses two issues that arise in Sacconi/faillo/ottone's essay. The first is the problem of compliance as it arises in social contract theory. The second is the problem of avoiding an incoherence that arises in the formulation of welfarist principles of distributive justice if these principles are taken to be concerned with the distribution of welfare without restriction. Sacconi, Faillo, and Ottone define an interesting class of principles that govern only the distribution of 'ma…Read more

    The Oxford handbook of ethical theory (edited book)
    Oxford University Press. 2006.
    The Oxford Handbook of Ethical Theory is a major new reference work in ethical theory consisting of commissioned essays by leading moral philosophers. Ethical theories have always been of central importance to philosophy, and remain so; ethical theory is one of the most active areas of philosophical research and teaching today. Courses in ethics are taught in colleges and universities at all levels, and ethical theory is the organizing principle for all of them. The Handbook is divided into two …Read more

    The central philosophical challenge of metaethics is to account for the normativity of moral judgment without abandoning or seriously compromising moral realism. In Morality in a Natural World, David Copp defends a version of naturalistic moral realism that can accommodate the normativity of morality. Moral naturalism is often thought to face special metaphysical, epistemological, and semantic problems as well as the difficulty in accounting for normativity. In the ten essays included in this vo…Read more

    The Iterated-Utilitarianism of J. S. Mill
    Canadian Journal of Philosophy 9 (sup1): 75-98. 1979.
    The interpretation of the utilitarianism of John Stuart Mill has been a matter of controversy at least since J.O. Urmson published his well known paper over twenty-five years ago. Urmson attributed to Mill a form of “rule-utilitarianism”, contrasting his reading with the “received view” on which Mill held a form of “act-utilitarianism”. Since then, the interpretive problem has typically been seen to be that of determining which of these two types of theory should be attributed to Mill, or, at le…Read more

    ABSTRACT: David Braybrooke argues that the core of the natural law theory of Thomas Aquinas survived in the work of Hobbes, Locke, Hume, and Rousseau. Much to my surprise, Braybrooke argues as well that David Copp’s society-centered moral theory is a secular version of this same natural law theory. Braybrooke makes a good case that there is an important idea about morality that is shared by the great philosophers in his group and that this idea is also found in Copp’s work. The idea is captured …Read more

    Social glue and norms of sociality
    Philosophical Studies 172 (12): 3387-3397. 2015.
    If we are going to understand morality, it is important to understand the nature of societies. What is fundamental to them? What is the glue that holds them together? What is the role of shared norm acceptance in constituting a society? Michael Bratman’s account of modest sociality in his book, Shared Agency, casts significant light on these issues. Bratman’s account focuses on small-scale interactions, but it is instructive of the kinds of factors that can enter into explaining sociality more g…Read more
