    Is Conscientiousness Always—or Ever—a Virtue?
    Dialogue 11 (2): 241-251. 1972.
    On most views of the nature of moral judgments, it is possible for a person to be mistaken in the belief that it is right to act in a certain way. When someone believes that it is right to do something, does that thing on the basis of such a belief, and yet in so doing commits deeds which are wrong by moral standards other than his own, we do not quite know whether to praise him for his conscientiousness while condemning his actions. He acts according to his conscience and does what he believes …Read more

    Trust and the problem of national reconciliation
    with Wilhelm Verwoerd
    Philosophy of the Social Sciences 32 (2): 178-205. 2002.
    The authors propose a conception of national reconciliation based on the building or rebuilding of trust between parties alienated by conflict. It is by no means obvious what reconciliation between large groups of people amounts to in practice or how it should be understood in theory. Lack of conceptual clarity can be illustrated with particular reference to postapartheid South Africa, where reconciliation between whites and blacks was a major goal of the Mandela government and the Truth and Rec…Read more

    What's Wrong with Slippery Slope Arguments?
    Canadian Journal of Philosophy 12 (2). 1982.
    Slippery slope arguments are commonly thought to be fallacious. But is there a single fallacy which they all commit? A study of applied logic texts reveals competing diagnoses of the supposed error, and several recent authors take slippery slope arguments seriously. Clearly, there is room for comment. I shall give evidence of divergence on the question of what sort of argument constitutes a slippery slope, distinguish four different types of argument which have all been deemed to be slippery slo…Read more

    Nuclear Illusion and Individual Obligations
    Canadian Journal of Philosophy 13 (4). 1983.
    Until very recently the topic of nuclear armaments and the prospects of global nuclear war have been relatively inconspicuous in the work of philosophers. With some exceptions, these and related themes have not figured prominently in the academic writings of philosophers; nor have they occupied space commensurate with their importance in courses and anthologies on applied ethics. Helen Caldicott's widely circulated film, ‘If You Love This Planet,’ and Jonathan Schell's moving book, The Fate of t…Read more

    How do Humans Think? How should we think? Almost all of philosophy and a great deal else depends in large part on the answers that we provide to such questions. Yet they are almost impossible to deal with in isolation; notions about nature of thought are almost bound to connect with metaphysical notions about where ideas come from, with notions about appropriate arenas for certainty, doubt, and belief, and hence with moral and religious ideas. The Western tradition of thinking about thinking tak…Read more
