    Perception and Extramission in De quantitate animae
    In Robert Pasnau (ed.), Oxford studies in medieval philosophy volume 9, Oxford University Press. pp. 1-39. 2021.
    Augustine is commonly interpreted as endorsing an extramission theory of perception in _De quantitate animae_. A close examination of the text shows, instead, that he is committed to its rejection. The discussion ends with some remarks about what it takes for an account of perception to be an extramission theory and with a review of the strength of evidence for attributing the extramission theory to Augustine on the basis of his other works.

    Priscian on Perception
    Phronesis 62 (4): 443-467. 2017.
    An aporia posed by Theophrastus prompts Priscian to describe the process by which perception formally assimilates to its object as a progressive perfection. I present an interpretation of Priscian’s account of perception’s progressive perfection, and I consider a dilemma for the general class of accounts to which Priscian’s belongs based on related problems raised by Plotinus and Aquinas. Doing so reveals the explanatory structure of Priscian’s account and the limitations of the general class of…Read more

    Open Questions and the Manifest Image
    Philosophy and Phenomenological Research 68 (2): 251-289. 2007.
    The essay argues that, on their usual metalinguistic reconstructions, the open question argument and Frege's puzzle are variants of the same argument. Each are arguments to a conclusion about a difference in meaning; each deploy compositionality as a premise; and each deploy a premise linking epistemic features of sentences with their meaning (which, given certain meaning‐platonist assumptions, can be interpreted as a universal instantiation of Leibniz's law). Given these parallels, each is soun…Read more

    Among the powers of living beings are intentional psychic powers, psychic powers that are of something. Thus, there is something seen, just as there is something feared or known. A puzzle arises when we consider whether these psychic powers might also be reflexive. Can these psychic powers be applied to themselves, or at least their exercise, such that the powers themselves, or their exercise, are their intentional objects? So, for example, in seeing what one does, and so being aware from within…Read more

    What is the relation between colors and our experience of them? A na?ve thought is this?the phenomenal character of color experience is determined by the qualitative character of the perceived color. When Norm perceives a red tomato, the qualitative character of his color experience is determined by the qualitative character of the color manifest in his experience of the tomato. If however, colors are mind- independent qualities of material objects, as they seem, pre-philosophically to be, then …Read more

    This is an essay on perception and its objects in the Timaeus. Two features of this work are noteworthy. First, the emphasis throughout is on Timaeus' views and not Plato's. Second, I show how broader aspects of Timaeus' cosmology are directly relevant to his philosophy of perception.

    Now with extra footnotes, by editorial demand! Final version accepted by Oxford Studies in Ancient Philosophy. This essay consists in a trick and a potential insight. The trick consists in a minimalist interpretation of color mixture. The account of color mixture is minimalist in the sense that, given certain background assumptions, there is no more to Timaeus’ account of color mixture than the list of the chromatic pathēmata and the list of how these combine to elicit perceptions of all the col…Read more

    Color and the inverted spectrum
    In Steven Davis (ed.), Vancouver Studies in Cognitive Science, Oxford University Press. pp. 187-214. 2000.
    If you trained someone to emit a particular sound at the sight of something red, another at the sight of something yellow, and so on for other colors, still he would not yet be describing objects by their colors. Though he might be a help to us in giving a description. A description is a representation of a distribution in a space (in that of time, for instance)

    Trinitarian Perception
    Aristotelian Society Supplementary Volume 91 (1): 21-41. 2017.
    We begin with a puzzle about how to intelligibly combine the active and passive elements of perception. For counsel, we turn to Augustine’s account of perception in De Trinitate. Augustine’s trinitarian account of perception offers an attractive resolution of our puzzle. Augustine’s resolution of our puzzle, however, cannot be straightforwardly adopted. It must be adapted. We end with speculation about how this might be done.

    Fictionalism in Metaphysics (edited book)
    Oxford University Press UK. 2005.
    Fictionalism is the view that a serious intellectual inquiry need not aim at truth. It came to prominence in philosophy in 1980, when Hartry Field argued that mathematics does not have to be true to be good, and Bas van Fraassen argued that the aim of science is not truth but empirical adequacy. Both suggested that the acceptance of a mathematical or scientific theory need not involve belief in its content. Thus the distinctive commitment of fictionalism is that acceptance in a given domain of i…Read more

    The transparency of truth
    Mind 106 (423): 475-497. 1997.
    Transparency is the following (alleged) property of truth: if one possesses the concept of truth, then to assert, believe, inquire whether it is true that S just is to assert, believe, inquire whether S (and conversely). It might appear (as it did to Frege in 'Thoughts') that if truth ascriptions were transparent, then the truth predicate must be redundant; but the fact that some truth ascriptions are not transparent-for instance, those that quantify over, name, or describe the proposition(s) to…Read more

    I defend and develop a traditional view in the metaphysics of sound, The Wave Theory of Sound. According The Wave Theory, as developed herein, sounds are not patterned disturbances so much as their propagation. And the propagation of a patterned disturbance is not a form of travel, but a dynamic in-formation, the wave-form successively inhering in diferently located parts of the dense and elastic medium. This conception, along with the assumption that we hear not only sounds but their sources, h…Read more

    Sound and Image
    In Christoph Limbeck-Lilienau & Friedrich Stadler (eds.), The Philosophy of Perception: Proceedings of the 40th International Ludwig Wittgenstein Symposium, De Gruyter. pp. 189-196. 2019.
    We hear sounds, and their sources, and their audible qualities. Sounds and their sources are essentially dynamic entities, not wholly present at any given moment, but unfolding through their temporal interval. Sounds and their sources, essentially dynamic entities, are the bearers or susbtrata of audible qualities. Audible qualities are qualities essentially sustained by activity. The only bearers of audible qualities present in auditory experience are essentially dynamic entities. Bodies are no…Read more

    The Trouble with Terminology
    Philosophical Books 49 (1): 33-41. 2008.
    Producing language that other people will be able to understand involves not just having a picture in your mind of the scenario…You have to deploy a shared linguistic system, according to established rules, using lexemes of known meaning, to present that picture to others in a way that will work for them. You have to consider whether there are other ways of viewing the situation at hand. You have to examine the wording you have chosen to see if it has ambiguities or unclarities. You have to put …Read more

    Respecting value
    European Journal of Philosophy 16 (3): 341-365. 2008.
    This conference is, in part, an expression of respect for Joseph Raz and his work from which we have all learned much. I thought it apt, then, to talk about Raz's (2001) views about respect as developed in chapter four of Value, Respect, and Attachment. Raz describes his views as having a Kantian origin. This might raise the eyebrow of some neo•Kantians or anyone inclined to interpret Kant as a formalist or as a constructivist. Nevertheless, I believe that Raz's views and Kant's, properly interp…Read more

    Sympathy in Perception
    Cambridge University Press. 2017.
    This is a book about the metaphysics of perception and discusses touch, audition, and vision. Though primarily concerned with the nature of perception, it draws heavily from the history of philosophy of perception, and connects the concerns of analytical and continental philosophers.

    Jimmy expresses sympathy for Scanlon’s contractualism but wonders whether it might be better developed in the context of a Humean expressivism. Jimmy presses this point, in part, by observing that much of what Scanlon wants to say about moral and normative discourse, such as their logical discipline and apparent truth-aptitude, can be accommodated by the expressivist. If all that Scanlon wants to say about moral and normative discourse can be accommodated by the expressivist then what content ca…Read more

    Color Illusion
    Noûs 45 (4): 751-775. 2011.
    As standardly conceived, an illusion is an experience of an object o appearing F where o is not in fact F. Paradigm examples of color illusion, however, do not fit this pattern. A diagnosis of this uncovers different sense of appearance talk that is the basis of a dilemma for the standard conception. The dilemma is only a challenge. But if the challenge cannot be met, then any conception of experience, such as representationalism, that is committed to the standard conception is false. Perhaps su…Read more

    In his 1904 letter to G.F. Stout, Cook Wilson distinguishes objective and sub- jective conceptions of appearance, and provides a diagnosis for the modern acceptance of the subjective conception in terms of a confused misdescrip- tion of the objective appearances that perceptual experience affords. More- over, Cook Wilson links subjective appearances with idealism, the suggestion being that perceptual appearances must be objective if they are to afford us with something akin to proof of a world w…Read more
