    On the Myth of Psychotherapy
    Philosophy Psychiatry and Psychology 32 (1): 67-80. 2025.
    Thomas Szasz famously argued that mental illness is a myth. Less famously, Szasz argued that since mental illness is a myth, so too is psychotherapy. Szasz's claim that mental illness is a myth has been much discussed, but much less attention has been paid to his claim that psychotherapy is a myth. In the first part of this essay, I critically examine Szasz's discussion of psychotherapy to uncover the strongest version of his case for thinking that it is a myth. As we'll see, this involves an un…Read more

    Experiences of derealization: A naive realist account
    Philosophical Psychology. forthcoming.
    A major symptom of “Derealization/Depersonalization Disorder” is derealization. People who experience derealization report a sense of unreality when it comes to their surroundings, yet they still perceive those surroundings. How can this possibly be accommodated by a naive realist theory of experience – a theory on which the real external world is central to explaining the phenomenology of perception? I develop this question into a new problem for naive realism: the problem of derealization. But…Read more

    Mental Health Pluralism
    Medicine, Health Care and Philosophy 28 (1): 65-81. 2025.
    In addressing the question of what mental health is we might proceed as if there is a single phenomenon – mental health – denoted by a single overarching concept. The task, then, is to provide an informative analysis of this concept which applies to all and only instances of mental health, and which illuminates what it is to be mentally healthy. In contrast, mental health pluralism is the idea that there are multiple mental health phenomena denoted by multiple concepts of mental health. Analysis…Read more

    Naive realists hold that experience is to be understood in terms of an intimate perceptual relation between a subject and aspects of the world, relative to a certain standpoint. Those aspects of the world themselves shape the contours of consciousness. But blurriness is an aspect of some of our experiences that does not seem to come from the world. I argue that this constitutes a significant challenge to some forms of naive realism. But I also argue that there is a robust form of naive realism w…Read more

    The Problem of Perception
    with Tim Crane
    Stanford Encyclopedia of Philosophy. 2021.
    The Problem of Perception is a pervasive and traditional problem about our ordinary conception of perceptual experience. The problem is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perceptual experience be what we ordinarily understand it to be: something that enables direct perception of the world? These possibilities of error challenge the intelligibility of our ordinary conception of perceptual experience; the major theories …Read more

    Austerity and Illusion
    Philosophers' Imprint 20 (15): 1-19. 2020.
    Many contemporary theorists charge that naïve realists are incapable of accounting for illusions. Various sophisticated proposals have been ventured to meet this charge. Here, we take a different approach and dispute whether the naïve realist owes any distinctive account of illusion. To this end, we begin with a simple, naïve account of veridical perception. We then examine the case that this account cannot be extended to illusions. By reconstructing an explicit version of this argument, we show…Read more

    Visual experiences seem to exhibit phenomenological particularity: when you look at some object, it – that particular object – looks some way to you. But experiences exhibit generality too: when you look at a distinct but qualitatively identical object, things seem the same to you as they did in seeing the first object. Naïve realist accounts of visual experience have often been thought to have a problem with each of these observations. It has been claimed that naïve realist views cannot account…Read more

    VII—Naive Realism and Diaphaneity
    Proceedings of the Aristotelian Society 118 (2): 149-175. 2018.
    Naïve Realists think that the ordinary mind-independent objects that we perceive are constitutive of the character of experience. Some understand this in terms of the idea that experience is diaphanous: that the conscious character of a perceptual experience is entirely constituted by its objects. My main goal here is to argue that Naïve Realists should reject this, but I’ll also highlight some suggestions as to how Naïve Realism might be developed in a non-diaphanous direction.

    Epistemological Disjunctivism and its Representational Commitments
    In Casey Doyle, Joseph Milburn & Duncan Pritchard (eds.), New Issues in Epistemological Disjunctivism, Routledge. 2019.
    Orthodox epistemological disjunctivism involves the idea that paradigm cases of visual perceptual knowledge are based on visual perceptual states which are propositional, and hence representational. Given this, the orthodox version of epistemological disjunctivism takes on controversial representational commitments in the philosophy of perception. Must epistemological disjunctivism involve these commitments? I don’t think so. Here I argue that we can take epistemological disjunctivism in a new d…Read more

    Bálint’s syndrome, Object Seeing, and Spatial Perception
    Mind and Language 33 (3): 221-241. 2018.
    Ordinary cases of object seeing involve the visual perception of space and spatial location. But does seeing an object require such spatial perception? An empirical challenge to the idea that it does comes from reflection upon Bálint's syndrome, for some suppose that in Bálint's syndrome subjects can see objects without seeing space or spatial location. In this article, I question whether the empirical evidence available to us adequately supports this understanding of Bálint's syndrome, and expl…Read more

    We are grateful to Ganson and Mehta (forthcoming) for their reply to our defence of phenomenal particularism against the objections raised by Mehta in his (2014). Their reply clarifies the nature of their objections to phenomenal particularism and helps identify the locus of our disagreements. In what follows we aim to defend phenomenal particularism against the objections raised in their reply.

    In a 2010 article Turri puts forward some powerful considerations which suggest that Williamson's view of knowledge as the most general factive mental state is false. Turri claims that this view is false since it is false that if S sees that p, then S knows that p. Turri argues that there are cases in which (A) S sees that p but (B) S does not know that p. In response I offer linguistic evidence to suppose that in propositional contexts “see” does not have the sort of meaning (a purely perceptua…Read more

    The Formulation of Epistemological Disjunctivism
    Philosophy and Phenomenological Research 92 (1): 86-104. 2016.
    I argue that we should question the orthodox way of thinking about epistemological disjunctivism. I suggest that we can formulate epistemological disjunctivism in terms of states of seeing things as opposed to states of seeing that p. Not only does this alternative formulation capture the core aspects of epistemological disjunctivism as standardly formulated, it has two salient advantages. First, it avoids a crucial problem that arises for a standard formulation of epistemological disjunctivism—…Read more

    On the Particularity of Experience
    with Anil Gomes
    Philosophical Studies 173 (2): 451-460. 2016.
    Phenomenal particularism is the view that particular external objects are sometimes part of the phenomenal character of perceptual experience. It is a central part of naïve realist or relational views of perception. We consider a series of recent objections to phenomenal particularism and argue that naïve realism has the resources to block them. In particular, we show that these objections rest on assumptions about the nature of phenomenal character that the naïve realist will reject, and that t…Read more

    The Invalidity of the Argument from Illusion
    American Philosophical Quarterly 55 (4): 357-364. 2018.
    The argument from illusion attempts to establish the bold claim that we are never perceptually aware of ordinary material objects. The argument has rightly received a great deal critical of scrutiny. But here we develop a criticism that, to our knowledge, has not hitherto been explored. We consider the canonical form of the argument as it is captured in contemporary expositions. There are two stages to our criticism. First, we show that the argument is invalid. Second, we identify premises that …Read more

    Knowledge and Ways of Knowing
    Proceedings of the Aristotelian Society 114 (3pt3): 353-364. 2014.
    Quassim Cassam offers a conception of ways of knowing which he argues is preferable to rival accounts such as the account we find in Williamson. The correct way to think about ways of knowing matters for philosophers, such as Cassam and Williamson, who want to understand knowledge itself in terms of ways of knowing. So is Cassam right that his conception of ways of knowing is preferable to Williamson's? The discussion to follow is irenic in spirit: I will argue that in fact Cassam and Williamson…Read more
