    Know-wh does not reduce to know that
    American Philosophical Quarterly 53 (2): 109-122. 2016.
    Know -wh ascriptions are ubiquitous in many languages. One standard analysis of know -wh is this: someone knows-wh just in case she knows that p, where p is an answer to the question included in the wh-clause. Additional conditions have also been proposed, but virtually all analyses assume that propositional knowledge of an answer is at least a necessary condition for knowledge-wh. This paper challenges this assumption, by arguing that there are cases where we have knowledge-wh without knowledge…Read more

    The Subject’s Point of View
    Oxford University Press. 2008.
    Descartes's philosophy has had a considerable influence on the modern conception of the mind, but many think that this influence has been largely negative. The main project of The Subject's Point of View is to argue that discarding certain elements of the Cartesian conception would be much more difficult than critics seem to allow, since it is tied to our understanding of basic notions, including the criteria for what makes someone a person, or one of us. The crucial feature of the Cartesian vie…Read more

    Indiscriminability and the sameness of appearance
    Proceedings of the Aristotelian Society 106 (2): 39-59. 2006.
    Abstract: How exactly should the relation between a veridical perception and a corresponding hallucination be understood? I argue that the epistemic notion of ‘indiscriminability’, understood as lacking evidence for the distinctness of things, is not suitable for defining this relation. Instead, we should say that a hallucination and a veridical perception involve the same phenomenal properties. This has further consequences for attempts to give necessary and sufficient conditions for the identi…Read more

    A sense of reality
    In Fiona Macpherson & Dimitris Platchias (eds.), Hallucination: Philosophy and Psychology, Mit Press. pp. 399-417. 2013.
    Hallucinations occur in a wide range of organic and psychological disorders, as well as in a small percentage of the normal population According to usual definitions in psychology and psychiatry, hallucinations are sensory experiences which present things that are not there, but are nonetheless accompanied by a powerful sense of reality. As Richard Bentall puts it, “the illusion of reality ... is the sine qua non of all hallucinatory experiences” (Bentall 1990: 82). The aim of this paper is to f…Read more

    What is externalism?
    Philosophical Studies 112 (3): 187-208. 2003.
    The content of the externalist thesis about the mind depends crucially on how we define the distinction between the internal and the external. According to the usual understanding, the boundary between the internal and the external is the skull or the skin of the subject. In this paper I argue that the usual understanding is inadequate, and that only the new understanding of the external/internal distinction I suggest helps us to understand the issue of the compatibility of externalism and privi…Read more

    Does twin earth rest on a mistake?
    Croatian Journal of Philosophy 3 (8): 155-169. 2003.
    In this paper I argue against Twin-Earth externalism. The mistake that Twin Earth arguments rest on is the failure to appreciate the force of the following dilemma. Some features of things around us do matter for the purposes of conceptual classification, and others do not. The most plausible way to draw this distinction is to see whether a certain feature enters the cognitive perspective of the experiencing subject in relation to the kind in question or not. If it does, we can trace conceptual …Read more
