    Perception and Objective Knowledge
    The Proceedings of the Twentieth World Congress of Philosophy 5 29-38. 2000.
    McDowell and Putnam are right to insist that objective knowledge is possible only because we are open to the world in perception, but neither of them offers an adequate account of the relationship between perception and perceptual judgments (which are at the core of our most fundamental knowledge of the world). This paper, intended as a contribution to the development of a sophisticated commonsense realism, proposes an account in terms of which perceptions acquire the status of perceptual judgme…Read more
  • This paper criticizes act-object accounts of experience and defends a version of the adverbial theory that is based on the assumption that sensory experiences always have propositional contents—in the sense that they do not represent bare individuals and properties, but whole states of affairs.

    Content and Causation in Perception
    Philosophy and Phenomenological Research 54 (4): 767-785. 1994.
    In order to perceive something, one must have a sense experience which it causes and which has a content that fits it appropriately. But veridical hallucinations show that more is required, viz., that the experience must also be caused by the object of perception in the right sort of way. The best account of what this amounts to is that the object causes the experience by means of a “reliable mechanism,” i.e., a causal mechanism which is generally apt to connect objects to experiences with conte…Read more

    Capitalist Exploitation, Self-Ownership, and Equality
    with Peter Hudson and Darrel Moellendorf
    Philosophical Forum 32 (3). 2001.
    Traditional Marxists hold that capitalist modes of production are unjustly exploitative. In 'Self-Ownership, Freedom and Equality' G. A. Cohen argues that this ``exploitation charge'' commits traditional Marxists to the thesis that people own themselves (``self-ownership''). If so, then traditional Marxism is vulnerable to a libertarian challenge to its commitment to equality. Cohen, therefore, recommends that Marxists abandon the exploitation charge. This paper undermines Cohen's case for the a…Read more

    This book explains Kant's major claims in the Critique of Pure Reason, how they hang together, and how Kant supports them, clarifying the way in which his reasoning unfolds over the course of this groundbreaking work. The book concentrates on key parts of the B edition that are essential to a basic understanding of Kant's project and provides a sympathetic account of Kant's reasoning about perception, space, time, judgment, substance, causation, objectivity, synthetic a priori knowledge, and the…Read more

    A Kantian Account of Animal Cognition
    Philosophical Forum 48 (4): 369-393. 2017.
    Kant holds that “on the basis of their actions” we can infer that “animals act in accordance with representations” (Critique of the Power of Judgment, 5: 464, fn.). Animals, like humans, have the powers of sensibility, imagination and choice, but lack the human powers of understanding, reason and free choice. They also lack first-person representation, consciousness, concepts and inner sense. Nevertheless, animals have an analog of reason that involves connections of representations that explain…Read more

    Perception and Objective Knowledge
    In The Proceedings of the Twentieth World Congress of Philosophy, Charlottesville: Philosophy Documentation Center. pp. 29-38. 2000.

  • Semantics for Conditionals
    Dissertation, University of the Witwatersrand, Johannesburg (South Africa). 1976.
  • Believing
    Dissertation, Indiana University. 1980.
    The emphasis in Part II is on the truth conditions of belief sentences. The chief aim is to show how the ontological account of belief advanced in Part I can serve as a basis for a theory of truth conditions for such sentences. The formal theory developed in Part II can, however, be discussed without reference to the earlier ontology. Chapter 11 presents the basic framework for the theory, and also deals with the truth conditions of the belief sentences which are construed as basic. In the later…Read more

    Objective Reasons
    Southern Journal of Philosophy 45 (4): 533-563. 2007.
    In order to establish that judgments about practical reasons can be objective, it is necessary to show that the applicable standards provide an adequate account of truth and error. This in turn requires that these standards yield an extensive set of substantive, publicly accessible judgments that are presumptively true. This output requirement is not satisfied by the standards of universalizability, consistency, coherence, and caution alone. But it is satisfied if we supplement them with the pri…Read more

    Facts as Truthmakers
    The Monist 69 (2): 177-188. 1986.
    Facts, I am pleased to observe, are back in fashion. For some time now they have had staunch friends in the American Midwest, and these days they are embraced as far afield as Sydney and San Francisco. But what are facts, and what facts are there? My answer to the first part of this question, which I shall not pursue further, is the same as Russell’s and the early Wittgenstein’s: Facts are what constitute the objective world, and what make true sentences and thoughts true and false sentences and…Read more

    Drawing on Stalnaker’s projection strategy, a revised version of the Ramsey test, and Dudman’s account of the evaluation of projective conditionals (e.g., “If Hitler invades England, Germany will win the war” and “If Hitler had invaded England, Germany would have won the war”), I offer a novel truth-conditional account of the semantics of a range of English conditionals. This account resolves some key puzzles in the philosophical literature about semantic differences between maximally similar co…Read more

    Reasons in Action
    Philosophical Papers 42 (3). 2013.
    When an agent performs an action because she takes something as a reason to do so, does she take it as a normative reason for the action or as an explanatory reason? In Reasons Without Rationalism, Setiya criticizes the normative view and advances a version of the explanatory view. This paper advances a version of the normative view and shows that it is not subject to Setiya's criticisms. It also shows that Setiya's explanatory account is subject to two fatal flaws, viz., that it raises question…Read more

    Making Sense of Kant’s Schematism
    Philosophy and Phenomenological Research 55 (4): 777-797. 1995.
    In this paper I advance an account of Kant’s Schematism according to which a schema in general is a pattern of imaginative synthesis that explains how intuitions have the content required for them to fall under a concept corresponding to the schema. An empirical schema is a pattern of imaginative synthesis that is responsive to the qualities of the sensations involved in the intuition which it synthesizes. A transcendental schema, in contrast, is not responsive to the particular qualities of the…Read more

    According to a common account, grammatical mood is merely a conventional indicator of force with no semantic significance. Focusing on indicatives, interrogatives and imperatives, I advance two reasons to reject this “force treatment” of mood. First, it can be shown that the mood of a subordinate clause can have semantic significance that affects the sense of a sentence in which it is embedded—which the force treatment cannot accommodate. Second, the speech acts of asserting, asking and ordering…Read more

    On the Semantics of Simple and Complex Demonstratives in English
    Southern Journal of Philosophy 39 (4): 487-505. 2001.
    According to a straightforward, conservative account of English demonstratives, simple and complex demonstratives are referring expressions belonging to the same semantic category (but they could be understood as either terms or quantifiers); the denotation of a complex demonstrative “dF” (if it has one) must satisfy the nominal “F” in “dF”; and both simple and complex demonstratives function as rigid designators. According to a recent alternative advanced by Lepore and Ludgwig, simple and compl…Read more

    Intentionality and Normativity
    South African Journal of Philosophy 17 (2): 142-151. 1998.
    The intentionality of virtually all thought that is distinctive of human beings is linguistically based and constitutively normative. As Robert Brandom claims in Making It Explicit, this normativity is best understood as having roots in social practice. But Brandom is wrong to insist that all intentionality is normative (thus denying intentionality to nonhuman, nonlinguistic animals). For even the simple social practices that ground the most primate norms presuppose robust nonnormative intention…Read more

    The Role of Imagination in Perception
    South African Journal of Philosophy 15 (4): 133-138. 1996.
    This article is an explication and defense of Kant’s view that ‘imagination is a necessary ingredient of perception itself’ (Critique of Pure Reason, A120, fn.). Imagination comes into perception at a far more basic level than Strawson allows, and it is required for the constitution of intuitions (= sense experiences) out of sense impressions. It also plays an important part in explaining how it is possible for intuitions to have intentional contents. These functions do not involve the applicati…Read more

    Thought and Language
    South African Journal of Philosophy 21 (3): 200-218. 2002.
    This article defends the view that nonlinguistic animals could be capable of thought (in the sense in which the mere possession of beliefs and desires is sufficient for thought). It is easy to identify flaws in Davidson's arguments for the thesis that thought depends upon language if one is open to the idea that some nonlinguistic animals have beliefs. It is, however, necessary to do more than this if one wishes to engage with the deeper challenge underlying Davidson's reasoning, viz., that of p…Read more

    Objectivism versus Realism
    Philosophical Forum 42 (1): 79-104. 2011.
    Realism about affirmations of a given type is the view that these affirmations are to be understood as assertions that attempt to describe a largely independent reality, and that they are correct if and only if they manage to do so (regardless of whether they can be known to be correct). Objectivisim about affirmations of a given type is the view that they are subject to adequate, non-arbitrary standards of correctness, and that there are a significant number of non-trivial affirmations of this …Read more
