    The Moral Basis of Vegetarianism
    Philosophy 53 (206). 1978.
    If someone abstains from meat-eating for reasons of taste or personal economics, no moral or philosophical question arises. But when a vegetarian attempts to persuade others that they, too, should adopt his diet, then what he says requires philosophical attention. While a vegetarian might argue in any number of ways, this essay will be concerned only with the argument for a vegetarian diet resting on a moral objection to the rearing and killing of animals for the human table. The vegetarian, in …Read more

    "Exists" and St. Anselm's Argument
    Grazer Philosophische Studien 3 (1): 59-70. 1977.
    This paper examines interpretations of the doctrine that "exists" is not a predicate (existence is not a property). None, it is concluded, is both true and a refutation of St. Anselm's "ontological" argument for the existence of God.

    Against Superkitten Ethics
    International Philosophical Quarterly 51 (4): 429-436. 2011.
    I here criticize the use of science-fiction examples in ethics, chiefly, though not solely, by defenders of abortion. We have no reliable intuitions concerning such examples—certainly nothing strong enough to set against the strong intuition that infanticide is virtually always wrong.

    Until recently, torture was regarded as an unthinkable act. But in the dark years following September 11, 2001, many people have defended it openly as they have many other kinds of action previously considered taboo. And the underlying issues are complicated. Yet at least a virtually absolute prohibition on interrogational torture can be rationally defended.

    One of the deepest problems in philosophical theology is that of divine causality and human freedom. The analogy between God and the author of a work of fiction can shed light on this and many other thorny problems in philosophical and dogmatic theology.

    On Slippery Slopes
    Philosophy 93 (3): 375-393. 2018.
    I here discuss an argument frequently dismissed as a fallacy – the slippery slope or camel's nose. The argument has three forms – analogical, argumentative, and prudential. None of these provides a deductive guarantee, but all can provide considerations capable of influencing the intellect. Our evaluation of such arguments reflects our background social and evaluative assumptions.

    What’s Wrong with Torture?
    International Philosophical Quarterly 49 (3): 317-332. 2009.
    Many of us want to say that there is an absolute—or at least a virtually absolute—prohibition on torturing people. But we live in a world in which firm moral restraints of all sorts are hard to defend. Neither contemporary conventional morality, nor any of the available moral theories, provides adequate support for the deliverances of the “wisdom of repugnance” in this area. Nor do they support casuistry capable of distinguishing torture from forms of rough treatment. I here make some suggestion…Read more

    Abortion: Three Perspectives
    with Michael Tooley, Celia Wolf-Devine, and Alison M. Jaggar
    Oup Usa. 2009.
    The newest addition to the Point/Counterpoint Series, Abortion: Three Perspectives features a debate between four noted philosophers - Michael Tooley, Celia Wolf-Devine, Philip E. Devine, and Alison M. Jaggar - presenting different perspectives on one of the most socially and politically argued issues of the past 30 years. The three main arguments include the "liberal" pro-choice approach, the "communitarian" pro-life approach, and the "gender justice" approach. Divided into two parts, the text …Read more

    Homicide Revisited
    Philosophy 55 (213): 329-347. 1980.
    Jonathan Glover and I, while not in such deep disagreement about the ethics of killing as to make all communication impossible, still disagree enough to make sustained confrontation worthwhile. At minimum, such confrontation should make it clear what are the most fundamental issues at stake in ethical arguments about various kinds of killing.
  • Justifying Terrorism: No Dogs or Philosophers Allowed
    with Ken Knisely, Robert Rafalko, and Scott Hibbard
    DVD. forthcoming.
    Can the use of terror as a political weapon ever be justified? What are the political implications of the struggle to define the concept of "terrorism"? Was the attack on the USS Cole a terrorist act? What role do the intentions of the terrorist and the state of mind of the victims play? Does the modern concept of the nation-state necessarily require the radical devaluation of the use of terror for political ends? With Robert Rafalko, Philip Devine, and Scott Hibbard

    The Structure of Conventional Morality
    International Philosophical Quarterly 45 (2): 243-256. 2005.
    In recent years, analytically trained philosophers have given extensive attention to various issues involved in the “culture wars,” including abortion, same-sex marriage, stem-cell research, and assisted suicide. There are, however, moral judgments that virtually no one questions. Defenses of adult-child sex, for example, are rare. There is also “conventional immorality”—the breach of conventional moral standards within roughly defined limits that at least limit the resulting damage to third par…Read more
