    The complaint is a familiar one: unelected, politically unaccountable judges are using their powers of judicial review to subvert the democratic process by shaping public policy in accordance with their own personal moral/political views. It is tempting to dismiss this complaint as the grumbling of those, usually on the political right, who have been disaffected by court decisions with which they personally disagree. But this temptation must be resisted, since the critics of judicial review, such as Jeremy Waldron, raise important (...)

    L. W. Sumner (2006). Utility and Capability. Utilitas 18 (1):1-19.
    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 differences may remain are less important (...)

    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, (...)

    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 pluralism that currently dominates moral philosophy, (...)

    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; (...)

    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 (...)

    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 welfarists should recognize that rights, however derivative, are capable of constraining appeals (...)

    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 managerial and professional positions, as well as the (...)

    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 dispel (...)
