    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

  • 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

    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

    How Demonstratives Denote
    Southern Journal of Philosophy 22 (1): 91-104. 1984.
    Focusing on the simple demonstrative ‘that’ and demonstrative expressions of the form ‘that F,’ this paper reviews four accounts of what determines the denotations of demonstratives—the description theory, according to which the work is done by a proper definite description associated with the demonstrative; the causal theory, according to which it is done by a non-deviant causal chain connecting the object and the demonstrative; the demonstration theory, according to which it is done by a demon…Read more

    Elementary Formal Semantics for English Tense and Aspect
    Philosophical Papers 21 (3): 215-241. 1992.
    This paper presents an approach to the elementary temporal semantics of the English tense system, the atoms of which are the present tense, the past tense, the progressive auxiliary, the perfective auxiliary, and the modal will as used for the future. It offers accounts of the forms of temporal semantics of core verb phrases of different categories and of the atoms of the tense system, using machinery that that yields appropriate compositional accounts of the temporal semantics of compound, tens…Read more

    Sensibility and Understanding in Perceptual Judgments
    South African Journal of Philosophy 18 (4): 356-369. 1999.
    The main aim of this paper is to work toward an account of how sensibility and understanding combine in perceptual judgments, with the emphasis on the role of sensibility in both the justification of such judgments and the explanation of how it is possible for them to apply to an objective world. I argue that in themselves sensory intuitions function as (animal level) beliefs about the environment, and that these beliefs have the status of perceptual judgments to the extent to which they are emb…Read more

    "Ought" Judgments and Motivation
    American Philosophical Quarterly 39 (2). 2002.
    Competing metaethical theories are sometimes cast as alternative ways of responding to an inconsistency between two apparent features of moral judgments, viz., that they are truth-apt expressions of belief and that they have motivational force. I argue that this is an oversimplification that fails to address some important data that can be accommodated on the basis of a straightforward “good reasons” account of “ought” judgments that explains why certain of these judgments have motivational forc…Read more

    How to Be a Normative Expressivist
    Philosophy and Phenomenological Research 80 (1): 182-207. 2009.
    Expressivism can make space for normative objectivity by treating normative stances as pro or con attitudes that can be correct or incorrect. And it can answer the logical challenges that bedevil it by treating a simple normative assertion not merely as an expression of a normative stance, but as an expression of the endorsement of a proposition that is true if and only if that normative stance is correct. Although this position has superficial similarities to normative realism, it does full jus…Read more

    Facts and Truth-Making
    Topoi 29 (2): 137-145. 2010.
    This essay is a reflection on the idea of truth-making and its applications. I respond to a critique of my 1986 paper on truth-making and discuss some key principles at play in the Truth-maker Program as it has emerged over the past 25 years, paying special attention to negative and general truths. I maintain my opposition to negative and general facts, but give an improved account of how to do without them. In the end, I accept Truth-maker Maximalism and a weakened form of Truth-maker Necessita…Read more

    Indexical Reference and the Ontology of Belief
    South African Journal of Philosophy 1 65-74. 1982.
    According to the propositional view of belief, a belief situation involves a believer’s standing in the relation of belief to a proposition. It is argued that the propositional view has unacceptable implications concerning the identity conditions of belief situations involving beliefs with indexical contents, especially where such beliefs are held over a period of time during which background circumstances change. After a critical discussion of Perry’s alternative to the propositional view, a ve…Read more

    Against the Careerist Conception of Well-Being
    Philosophical Forum 31 (1). 2000.
    According to “the careerist conception of well-being,” a worthwhile life must involve the realization of a life plan that the agent has freely, consciously, and reflectively chosen from a position of self-knowledge and realistic foresight about her like future circumstances; that it includes the setting of short-, medium, and long-term challenges based on that overall plan, and ongoing success at meeting these challenges. This conception of well-being expresses a live philosophical position, but…Read more

    Sense Experiences and Their Contents: A Defense of the Propositional Account
    Inquiry: An Interdisciplinary Journal of Philosophy 33 (2): 215-30. 1990.
    A number of philosophers are committed to the view that sense experiences, in so far as they have contents, have propositional contents, but this is more often tacitly accepted than argued for in the literature. This paper explains the propositional account and presents a basic case in support of it in a simple and straightforward way which does not involve commitment to any specific philosophical theory of perception

    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
