• The concept of the aesthetic
    Stanford Encyclopedia of Philosophy. 2017.
    Introduced into the philosophical lexicon during the Eighteenth Century, the term ‘aesthetic’ has come to be used to designate, among other things, a kind of object, a kind of judgment, a kind of attitude, a kind of experience, and a kind of value. For the most part, aesthetic theories have divided over questions particular to one or another of these designations: whether artworks are necessarily aesthetic objects; how to square the allegedly perceptual basis of aesthetic judgments with the fact…Read more
  • Eighteenth Century British Aesthetics
    Stanford Encyclopedia of Philosophy. 2018.
    18th-century British aesthetics addressed itself to a variety of questions: What is taste? What is beauty? Is there is a standard of taste and of beauty? What is the relation between the beauty of nature and that of artistic representation? What is the relation between one fine art and another? How ought the fine arts be ranked one against another? What is the nature of the sublime and ought it be ranked with the beautiful? What is the nature of genius and what is its relation to taste? Although…Read more

  • Intelligible Beauty
    Aristotelian Society Supplementary Volume 96 (1): 147-164. 2022.
    Arthur Danto argued from the premiss that artworks are essentially cognitive to the conclusion that they are incidentally aesthetic. I wonder why Danto, and the very many of us he persuaded, came to believe that the cognitive and the aesthetic oppose one another. I argue, contrary to Danto’s historical claims, that the cognitive and the aesthetic did not come into opposition until the late nineteenth or early twentieth century, and that they were brought into opposition for reasons of art-critic…Read more

  • Six Encounters with Bolzano’s Aesthetics
    Estetika: The European Journal of Aesthetics 63 (1): 89-112. forthcoming.
    The symposium comprises six short reflections on Bernard Bolzano’s essays in aesthetics. James Shelley and Mohan Matthen treat the theories of beauty and the arts in their own terms, Jennifer Judkins approaches Bolzano from the perspective of musical performance practice, and Claire Kirwin, Katalin Makkai, and Sandra Shapshay put Bolzano in dialogue with Immanuel Kant, Arthur Schopenhauer, and Friedrich Nietzsche.
  • Most students of philosophy, at one time or another, have worked through Descartes' Meditations and witnessed this reduction of the world to the res cogitans and consequent attempt to recover the real, or extra-mental, world through proofs for God's existence and divine veracity. Whatever our final assessment of the validity and soundness of these proofs may be, there can be no doubt that the judgment of history is that they fail, leaving Descartes' conception of the self forever confined to the…Read more
  • Last year, as some of you may recall, I took it upon my chairly shoulders to solve the problem of causation, where this problem can be stated this way: What is causation? According to the analysis I offered, C is a cause of E if and only if C makes E happen. I am happy to report that, in the year since delivering this account of causation, no objections have arisen. The critics have been silenced. Indeed, my colleague Dan Hausman, the Herbert Simon Professor of Philosophy, reports that he is no …Read more
  • Why flatulence is funny

The backfire, bant, bucksnort, booty bomb, colon cologne, drifter, fanny bubble, gasser, gurgler, moon beam, nether belch, pants puffer, pooh tune, rip-snort, sphincter whistle, thunder dumpling, tush tickler, and trouser cough. These are synonyms for a bodily function that is as natural as breathing, eating, or sleeping. Yet unlike other physiological functions, the ‘flatus’ is a source of e…Read more

  • A Propositional Theory of Truth
    Notre Dame Journal of Formal Logic 59 (4): 503-545. 2018.
    The liar and kindred paradoxes show that we can derive contradictions if our language possesses sentences lending themselves to paradox and we reason classically from schema about truth: Sis true iffp, where the letter p is to be replaced with a sentence and the letter S with a name of that sentence. This article presents a theory of truth that keeps at the expense of classical logic. The theory is couched in a language that possesses paradoxical sentences. It incorporates all the instances of t…Read more
  • Classical Logic and the Liar
    Logic and Logical Philosophy 29 (1): 35-56. 2020.
    The liar and kindred paradoxes show that we can derive contradictions when we reason in accordance with classical logic from the schema (T) about truth: S is true iff p, where ‘p’ is to be replaced with a sentence and ‘S’ with a name of that sentence. The paper presents two arguments to the effect that the blame lies not with (T) but with classical logic. The arguments derive contradictions using classical logic, but instead of appealing to (T), they invoke semantic claims that seem even harder …Read more
  • An Argument for Existentialism
    Acta Analytica 35 (4): 507-520. 2020.
    Existentialism about propositions is the view that a proposition expressed in a sentence containing a nonempty name or indexical depends ontologically on the referent of the name or indexical: the proposition could not exist if the referent did not. The paper focuses on names. It discusses some arguments for existentialism and then presents a novel one. That argument does not presuppose that propositions have constituents, and it could be accepted by those who hold broadly Fregean views about na…Read more

    Ratio 35 (2): 104-111. 2022.
    Ratio, Volume 35, Issue 2, Page 104-111, June 2022.
  • If we wish to formulate an axiomatic truth-theory interpreting a modal language and treat the symbol of necessity as a sentential operator and not as a quantifier over possible worlds, there arise various problems. These are due partly to the fact that words could have meant something other than what they actually mean and partly to certain principles of modal metaphysics. One of those principles is existentialism about propositions: a proposition that is expressed in a sentence containing a non…Read more
  • A theory of truth
    Cambridge University Press. 2024.
    The paradoxes about truth are the subject of extensive research. Developing an original approach, this book argues that we should diverge from classical logic and presents a number of formal theories of truth. Also included is a beginner-friendly introduction to semantic paradoxes, and a discussion of alternative non-classical theories.
  • Moral realism
    Philosophical Review 95 (2): 163-207. 1986.
  • Master's Dissertation (Awarded Distinction from Warwick University – assessed by Professors Stephen Houlgate and Christine Battersby, 2002)
  • The thesis that follows proffers a solution to the mind-matter problem, the problem as to how mind and matter relate. The proposed solution herein is a variant of panpsychism – the theory that all (pan) has minds (psyche) – that we name pansentient monism. By defining the suffix 'psyche' of panpsychism, i.e. by analysing what 'mind' is (Chapter 1), we thereby initiate the effacement of the distinction between mind and matter, and thus advance a monism. We thereafter critically examine the preval…Read more

  • Pantheism: One and all
    Philosophical Psychology 38 (7): 3292-3317. 2025.
    Pantheism – All is God – is the hidden doctrine behind many reported psychedelic-occasioned experiences, both in the literature and in clinical trials, yet its meaning is little understood in the clinical and therapeutic spheres. This essay therefore seeks to remedy this deficit by offering a fresh outline of Pantheism via the exploration of its etymology and history, the meanings of pan/all and theos/God, before traveling into a Pantheism typology that covers the two veritable varieties, Monist…Read more
