282Imaginative Synthesis and the Basic Function of the Second Part of Kant’s Transcendental Deduction in BEuropean Journal of Philosophy 34 33-50. 2026.Most recent commentators on Kant’s Transcendental Deduction assume that the main purpose of the second part of the B-Deduction (“BD2") is to show that human intuitions must fall under categories for reasons connected with their spatio-temporal form. But there are good reasons to hold that the Deduction as a whole is concerned with pure categories, whose application to spatio-temporal objects is undetermined. If so, BD2 cannot establish a connection between the categories and the spatio-temporal …Read more

156Kant's Account of Our Representation of Space: The Form of Intuition, Synthesis, and the Formal IntuitionKant Yearbook 17 51-74. 2025.I take a new approach to the problem of interpreting the controversial footnote on B160-1 of Kant’s first Critique, focusing on philosophical considerations about conditions under which synthesis is required for the representation of properties of space, and I argue for the following position. The form of outer intuition, which does not involve synthesis, represents the three-dimensionality, continuity, holism and uniformity of space; but it cannot represent space’s singularity, because the form…Read more

96Perception and Objective KnowledgeIn Brian P. McLaughlin (ed.), The Proceedings of the Twentieth World Congress of Philosophy, Volume 5: Epistemology, Charlottesville: Philosophy Documentation Center. pp. 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

In Defence of the Adverbial Theory of ExperienceIn William J. Rapaport & Francesco Orilia (eds.), Thought, Language, and Ontology, Essays in Memory of Hector-Neri Castaneda, Kluwer Academic Publishers. pp. 95-106. 1998.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.

186Content and Causation in PerceptionPhilosophy 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

187Capitalist Exploitation, Self-Ownership, and EqualityPhilosophical 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

57Making Sense of Kant's Critique of Pure Reason: A Philosophical IntroductionBloomsbury Academic. 2022.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

103A Kantian Account of Animal CognitionPhilosophical 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

BelievingDissertation, 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

105Against the Careerist Conception of Well-BeingPhilosophical 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

215On the Semantics of Simple and Complex Demonstratives in EnglishSouthern 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

186Facts as TruthmakersThe 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

3193The Role of Imagination in PerceptionSouth 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

534Making Sense of Kant’s SchematismPhilosophy 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

121Against the Power of Force: Reflections on the Meaning of MoodMind 95 (379): 361-372. 1986.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

120Thought and LanguageSouth 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

2967Objectivism versus RealismPhilosophical 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

802Intentionality and NormativitySouth 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

134Sensibility and Understanding in Perceptual JudgmentsSouth 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

107"Ought" Judgments and MotivationAmerican 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
