    The moral foundation of rights
    Oxford University Press. 1987.
    What does it mean for someone to have a moral right to something? What kinds of creatures can have rights, and which rights can they have? While rights are indispensable to our moral and political thinking, they are also mysterious and controversial; as long as these controversies remain unsolved, rights will remain vulnerable to skepticism. Here, Sumner constructs both a coherent concept of a moral right and a workable substantive theory of rights to provide the moral foundation necessary to di…Read more

    Welfare, happiness, and ethics
    Oxford University Press. 1996.
    Moral philosophers agree that welfare matters. But they disagree about what it is, or how much it matters. In this vital new work, Wayne Sumner presents an original theory of welfare, investigating its nature and discussing its importance. He considers and rejects all notable theories of welfare, both objective and subjective, including hedonism and theories founded on desire or preference. His own theory connects welfare closely with happiness or life satisfaction. Reacting against the value pl…Read more

    When medical assistance in dying (MAiD) was legalized in Canada in June 2016, the question of allowing decisionally capable persons to make advance requests in anticipation of later incapacity was reserved for further consideration during the mandatory parliamentary review originally scheduled to begin in June 2020 (but since delayed by COVID-19). In its current form the legislation does not permit such requests, since it stipulates that at the time at which the procedure is to be administered …Read more

    Hate speech, understood broadly, is any form of expression intended to arouse hatred or contempt toward members of a particular social group. When university administrators have reason to believe that a planned speaking event on campus may feature hate speech (at least in the eyes of some), how should they respond? In this paper I address this question as it arises for Canadian universities. I argue that, where the regulation of campus speech is concerned, the right course of action for unive…Read more

    Utility and Capability
    Utilitas 18 (1): 1-19. 2006.
    When Amartya Sen defends his capability theory of well-being he contrasts it with the utility theory advocated by the classical utilitarians, including John Stuart Mill. Yet a closer examination of the two theories reveals that they are much more similar than they appear. Each theory can be interpreted in either a subjective or an objective way. When both are interpreted subjectively the differences between them are slight, and likewise for the objective interpretations. Finally, whatever differ…Read more

    Welfare, Happiness, and Pleasure
    Utilitas 4 (2): 199-223. 1992.
    Time and philosophical fashion have not been kind to hedonism. After flourishing for three centuries or so in its native empiricist habitat, it has latterly all but disappeared from the scene. Does it now merit even passing attention, for other than nostalgic purposes? Like endangered species, discredited ideas do sometimes manage to make a comeback. Is hedonism due for a revival of this sort? Perhaps it is overly optimistic to think that it could ever flourish again in its original form; the ev…Read more

    Two Theories of the Good: L. W. SUMNER
    Social Philosophy and Policy 9 (2): 1-14. 1992.
    Suppose that the ultimate point of ethics is to make the world a better place. If it is, we must face the question: better in what respect? If the good is prior to the right — that is, if the rationale for all requirements of the right is that they serve to further the good in one way or another — then what is this good? Is there a single fundamental value capable of underlying and unifying all of our moral categories? If so, how might it defeat the claims of rival candidates for this role? If n…Read more

    Animal welfare and animal rights
    Journal of Medicine and Philosophy 13 (2): 159-175. 1988.
    Animal liberationists tend to divide into two mutually antagonistic camps: animal welfarists, who share a utilitarian moral outlook, and animal rightists, who presuppose a structure of basic rights. However, the gap between these groups tends to be exaggerated by their allegiance to oversimplified versions of their favored moral frameworks. For their part, animal rightists should acknowledge that rights, however basic, are also defeasible by appeals to consequences. Contrariwise, animal welfaris…Read more

    Is Virtue Its Own Reward?: L. W. SUMNER
    Social Philosophy and Policy 15 (1): 18-36. 1998.
    If I lead a life of virtue, that may well be good for you. But will it also be good for me? The idea that it will—or even must—is an ancient one, and its appeal runs deep. For if this idea is correct then we can provide everyone with a good reason—arguably the best reason—for being virtuous. However, for all the effort which has been invested in defending the idea, by some of the best minds in the history of philosophy, it remains unproven. Worse, in this skeptical age hardly anyone really belie…Read more

    I am grateful to John Woods and David Soles for the careful attention they have given to some of the central arguments of Abortion and Moral Theory, though I wish that they had revealed fewer respects in which those arguments were seriously underdeveloped. In what follows I will try to supply some of the needed further development. I address the main points at issue in what I conceive to be their order of ascending importance.

    Positive Sexism
    Social Philosophy and Policy 5 (1): 204. 1987.
    No one who cares about equal opportunity can derive much comfort from the present occupational distribution of working women. In the various industrial societies of the West, women comprise between one quarter and one-half of the national labor force. However, they tend to clustered in employment sectors – especially clerical, sales, and service J occupations – which rank relatively low in remuneration, status, autonomy, and other perquisites. Meanwhile, the more prestigious and rewarding manage…Read more

    Toward a Credible View of Abortion
    Canadian Journal of Philosophy 4 (1). 1974.
    As little as a decade ago most moral philosophers still believed that the exercise of their craft did not include defending positions on actual moral problems. More recently they have come to their senses, one happy result being a spate of articles in the last few years on the subject of abortion. These discussions have contributed much toward an understanding of the abortion issue, but for the most part they have not attempted a full analysis of the morality of abortion. Such an analysis is too…Read more
