About me
Douglas W. Portmore is an Associate Professor of Philosophy in the School of Historical, Philosophical, and Religious Studies at Arizona State University. His research focuses mainly on morality, rationality, and the interconnections between the two, but he also writes on wellbeing, posthumous harm, and the nonidentity problem. He is currently finishing up work on a book entitled: Commonsense Consequentialism: Wherein Morality Meets Rationality, which is forthcoming with Oxford University Press as part of a new series of books that David Copp is editing entitled “Oxford Moral Theory.” The book defends a version of consequentialism that both comports with our commonsense moral convictions and shares with other consequentialist theories the same compelling teleological conception of practical reasons. Portmore is also the author of several journal articles, appearing in Noûs, Mind, Ethics, Ratio, Utilitas, Philosophical Studies, Philosophy Compass, Pacific Philosophical Quarterly, American Philosophical Quarterly, Oxford Studies in Normative Ethics, Ethical Theory and Moral Practice, and the Journal of Ethics and Social Philosophy. Before coming to Arizona State University, he taught at the College of Charleston and California State University, Northridge. He received a bachelor's in philosophy and political science from the University of California, San Diego, and master's and doctorate degrees in philosophy from the University of California, Santa Barbara. During the 2008-09 academic year, he was a Faculty Fellow at the Center for Ethics and Public Affairs, Murphy Institute, Tulane University. Portmore is also one of the founding members and current co-editor of PEA Soup, a blog dedicated to the discussion of philosophy, ethics, and academia.

  1. Douglas W. Portmore, Consequentializing Commonsense Morality.
    This is Chapter 4 of my Commonsense Consequentialism: Wherein Morality Meets Rationality. In this chapter, I argue that that any plausible nonconsequentialist theory can be consequentialized, which is to say that, for any plausible nonconsequentialist theory, we can construct a consequentialist theory that yields the exact same set of deontic verdicts that it yields.

  2. Douglas W. Portmore, Chapter 5: Dual-Ranking Act-Consequentialism: Reasons, Morality, and Overridingness.
    This is Chapter 5 of my Commonsense Consequentialism: Wherein Morality Meets Rationality. In this chapter, I argue that those who wish to accommodate typical instances of supererogation and agent-centered options must deny that moral reasons are morally overriding and accept both that the reason that agents have to promote their own self-interest is a non-moral reason and that this reason can, and sometimes does, prevent the moral reason that they have to sacrifice their self-interest so as to do more to (...)

  3. Douglas W. Portmore, Chapter 3: The Teleological Conception of Practical Reasons.
    This is Chapter 3 of my Commonsense Consequentialism: Wherein Morality Meets Rationality. In this chapter, I defend the teleological conception of practical reasons, which holds that the reasons there are for and against performing a given act are wholly determined by the reasons there are for and against preferring its outcome to those of its available alternatives, such that, if S has most reason to perform x, all things considered, then, of all the outcomes that S could bring about, S (...)

  4. Douglas W. Portmore, What Are Our Options?
    We ought to perform our best option—that is, the option that we have most reason, all things considered, to perform. This is perhaps the most fundamental and least controversial of all normative principles concerning action. Yet, it is not, I believe, well understood. For even setting aside questions about what our reasons are and about how best to formulate the principle, there is a question about how we should construe our options. This question is of the upmost importance, for which (...)

  8. Douglas W. Portmore (forthcoming). Consequentialism and Moral Rationalism. Oxford Studies in Normative Ethics.
    I argue that we should reject all traditional forms of act-consequentialism if moral rationalism is true. (Moral rationalism, as I define it, holds that if S is morally required to perform x, then S has decisive reason, all things considered, to perform x.) I argue that moral rationalism in conjunction with a certain conception of practical reasons (viz., the teleological conception of reasons) compels us to accept act-consequentialism. I give a presumptive argument in favor of moral rationalism. And I argue (...)

    I argue that rule consequentialism sometimes requires us to act in ways that we lack sufficient reason to act. And this presents a dilemma for Parfit. Either Parfit should concede that we should reject rule consequentialism (and, hence, Triple Theory, which implies it) despite the putatively strong reasons that he believes we have for accepting the view or he should deny that morality has the importance he attributes to it. For if morality is such that we sometimes have decisive reason (...)

This is perhaps the most fundamental and least controversial of all normative principles concerning action. Yet, it is not, I believe, well understood. For even setting aside questions about what our options are and what our reasons are, there are prior questions concerning how best to formulate the principle.

    Agents often face a choice of what to do. And it seems that, in most of these choice situations, the relevant reasons do not require performing some particular act, but instead permit performing any of numerous act alternatives. This is known as the basic belief. Below, I argue that the best explanation for the basic belief is not that the relevant reasons are incommensurable (Raz) or that their justifying strength exceeds the requiring strength of opposing reasons (Gert), but that they (...)

    It is through our actions that we affect the way the world goes. Whenever we face a choice of what to do, we also face a choice of which of various possible worlds to actualize. Moreover, whenever we act intentionally, we act with the aim of making the world go a certain way. It is only natural, then, to suppose that an agent’s reasons for action are a function of her reasons for preferring some of these possible worlds to others, (...)

    A growing trend of thought has it that any plausible nonconsequentialist theory can be consequentialized, which is to say that it can be given a consequentialist representation. In this essay, I explore both whether this claim is true and what its implications are. I also explain the procedure for consequentializing a nonconsequentialist theory and give an account of the motivation for doing so.

    AS MANY OF us know, millions of people on this planet are suffering for lack of potable water, basic healthcare, and adequate nutrition. And, as many of us also know, we (the well‐to‐do) could alleviate and/or prevent some of this suffering by making certain sacrifices, e.g., by donating some of our incomes to organizations such as Oxfam and UNICEF. Suppose, then, that we are wondering to what extent each of us is morally obligated to make sacrifices for the sake of (...)

    In this paper, I argue that those moral theorists who wish to accommodate agentcentered options and supererogatory acts must accept both that the reason an agent has to promote her own interests is a nonmoral reason and that this nonmoral reason can prevent the moral reason she has to sacrifice those interests for the sake of doing more to promote the interests of others from generating a moral requirement to do so. These theorists must, then, deny that moral reasons morally (...)

    Dual-ranking act-consequentialism (DRAC) is a rather peculiar version of act-consequentialism. Unlike more traditional forms of act-consequentialism, DRAC doesn’t take the deontic status of an action to be a function of some evaluative ranking of outcomes. Rather, it takes the deontic status of an action to be a function of some non-evaluative ranking that is in turn a function of two auxiliary rankings that are evaluative. I argue that DRAC is promising in that it can accommodate certain features of commonsense morality (...)

    To consequentialize a non-consequentialist theory, take whatever considerations that the non-consequentialist theory holds to be relevant to determining the deontic statuses of actions and insist that those considerations are relevant to determining the proper ranking of outcomes. In this way, the consequentialist can produce an ordering of outcomes that when combined with her criterion of rightness yields the same set of deontic verdicts that the non-consequentialist theory yields. In this paper, I argue that any plausible non-consequentialist theory can be consequentialized. (...)

    This paper argues that the standard account of posthumous harm is untenable. The standard account presupposes the desire-fulfillment theory of welfare, but I argue that no plausible version of this theory can allow for the possibility of posthumous harm. I argue that there are, at least, two problems with the standard account from the perspective of a desire-fulfillment theorist. First, as most desire-fulfillment theorists acknowledge, the theory must be restricted in such a way that only those desires that pertain to (...)

    Many philosophers hold that the achievement of one’s goals can contribute to one’s welfare apart from whatever independent contributions that the objects of those goals, or the processes by which they are achieved, make. Call this the Achievement View, and call those who accept it achievementists. In this paper, I argue that achievementists should accept both (a) that one factor that affects how much the achievement of a goal contributes to one’s welfare is the amount that one has invested in (...)

    Consequentialism is an agent-neutral teleological theory, and deontology is an agent-relative non-teleological theory. I argue that a certain hybrid of the two—namely, non-egoistic agent-relative teleological ethics (NATE)—is quite promising. This hybrid takes what is best from both consequentialism and deontology while leaving behind the problems associated with each. Like consequentialism and unlike deontology, NATE can accommodate the compelling idea that it is always permissible to bring about the best available state of affairs. Yet unlike consequentialism and like deontology, NATE accords (...)

    In this paper, I argue that maximizing act-consequentialism (MAC)—the theory that holds that agents ought always to act so as to produce the best available state of affairs—can accommodate both agent-centered options and supererogatory acts. Thus I will show that MAC can accommodate the view that agents often have the moral option of either pursuing their own personal interests or sacrificing those interests for the sake of the impersonal good. And I will show that MAC can accommodate the idea that (...)

    A theory is agent neutral if it gives every agent the same set of aims and agent relative otherwise. Most philosophers take act-consequentialism to be agent-neutral, but I argue that at the heart of consequentialism is the idea that all acts are morally permissible in virtue of their propensity to promote value and that, given this, it is possible to have a theory that is both agent-relative and act-consequentialist. Furthermore, I demonstrate that agent-relative act-consequentialism can avoid the counterintuitive implications associated (...)

    On commonsense morality, there are two types of situations where an agent is not required to maximize the impersonal good. First, there are those situations where the agent is prohibited from doing so--constraints. Second, there are those situations where the agent is permitted to do so but also has the option of doing something else--options. I argue that there are three possible explanations for the absence of a moral requirement to maximize the impersonal good and that the commonsense moralist must (...)

    On the Total Principle, the best state of affairs (ceteris paribus) is the one with the greatest net sum of welfare value. Parfit rejects this principle, because he believes that it implies the Repugnant Conclusion, the conclusion that for any large population of people, all with lives well worth living, there will be some much larger population whose existence would be better, even though its members all have lives that are only barely worth living. Recently, however, a number of philosophers (...)

    Consequentialism is usually thought to be unable to accommodate many of our commonsense moral intuitions. In particular, it has seemed incompatible with the intuition that agents should not violate someone's rights even in order to prevent numerous others from committing comparable rights violations. Nevertheless, I argue that a certain form of consequentialism can accommodate this intuition: agent-relative consequentialism--the view according to which agents ought always to bring about what is, from their own individual perspective, the best available outcome. Moreover, I (...)

I then argue that we should opt for (...)

    WHEN ONE ASSUMES, as I will, that death marks the irrevocable end to one’s existence, it is difficult to make sense of the idea that a person could be harmed or benefited by events that take place after her death. How could a posthumous event either enhance or diminish the welfare of the deceased, who no longer exists? Yet we find that many people have a prudential (i.e., self-interested) concern for what’s going to happen after their deaths.1 People are, for (...)
