    The Demand for Justification in Ethics
    Journal of Philosophical Research 15 1-14. 1990.
    The common belief that the epistemic credentials of ethics are quite questionable, and therefore in need of special justification, is an illusion made possible by the logical gap between reason and belief. This gap manifests itself sometimes even outside ethics. In ethics its manifestations are common, because of the practical nature of ethics. The attempt to cover it up takes the form of exorbitant demands for justification and often leads to espousing noncognitivism.

    The Metaphysics of G.E. Moore (review)
    Review of Metaphysics 37 (4): 868-870. 1984.
    This book is a welcome addition to the growing literature on the classics of analytic philosophy. O'Connor's discussion of Moore's philosophy is intelligent, useful, and generally accurate and informed. The title of the book is somewhat misleading. For O'Connor discusses all major parts of Moore's philosophy except his ethics. Hence much of the book is concerned with Moore's defense of common sense, his philosophy of perception, and his conception of analysis, topics that have received much atte…Read more

    The Examined Life (review)
    Review of Metaphysics 43 (2): 406-408. 1989.
    This is a welcome addition to the growing literature in an ethics that is unself-consciously and unabashedly normative. It is concerned with what good lives are and how they can be achieved. At least in civilized contexts, good lives depend on self-direction, which itself depends on possessing the virtues of self-control, self-knowledge, moral sensitivity, and wisdom. These are discussed in detail and with insight. The other-regarding virtues of justice and benevolence are also acknowledged but …Read more

    Skepticism About the External World
    Oxford University Press. 1998.
    One of the most important and perennially debated philosophical questions is whether we can have knowledge of the external world. Butchvarov here considers whether and how skepticism with regard to such knowledge can be refuted or at least answered. He argues that only a direct realist view of perception has any hope of providing a compelling response to the skeptic and introduces the radical innovation that the direct object of perceptual, and even dreaming and hallucinatory, experience is alwa…Read more

    Reality (review)
    Philosophy and Phenomenological Research 67 (2): 497-500. 2003.
    This is not a textbook or an introduction. It is an important original contribution to metaphysics. Professor Loptson sees metaphysics as “the most general science,” and correctly points out that this is how, though under different names, it was understood by Democritus, Aristotle, Descartes, Locke, Leibniz, and of course many others.

    Our Robust Sense of ReaUty
    Grazer Philosophische Studien 25 (1): 403-421. 1985.
    Anti-Meinongian philosophers, such as Russell, do not explain what they mean by existence when they deny that there are nonexistent objects — they just sense robustly. I argue that any plausible explanation of what they mean tends to undermine their view and to support the Meinongian view. But why are they so strongly convinced that they are right? I argue that the reason is to be found in the special character of the concept of existence, which has been insufficiently examined by anti-Meinongia…Read more
