    Multi-level computational methods for interdisciplinary research in the HathiTrust Digital Library
    with Jaimie Murdock, Colin Allen, Katy Börner, Robert Light, Simon McAlister, Andrew Ravenscroft, Robert Rose, Doori Rose, Jun Otsuka, John Lawrence, and Chris Reed
    PLoS ONE 12 (9). 2017.
    We show how faceted search using a combination of traditional classification systems and mixed-membership topic models can go beyond keyword search to inform resource discovery, hypothesis formulation, and argument extraction for interdisciplinary research. Our test domain is the history and philosophy of scientific work on animal mind and cognition. The methods can be generalized to other research areas and ultimately support a system for semi-automatic identification of argument structures. We…Read more

    In this paper we look at the manual analysis of arguments and how this compares to the current state of automatic argument analysis. These considerations are used to develop a new approach combining a machine learning algorithm to extract propositions from text, with a topic model to determine argument structure. The results of this method are compared to a manual analysis.

    This paper aims to shed new light on certain philosophical theories of perceptual experience by examining the semantics of perceptual ascriptions such as “Jones sees an apple.” I start with the assumption, recently defended elsewhere, that perceptual ascriptions lend themselves to intensional readings. In the first part of the paper, I defend three theses regarding such readings: I) intensional readings of perceptual ascriptions ascribe phenomenal properties, II) perceptual verbs are not ambiguo…Read more

    Representationalism and Sensory Modalities: An Argument for Intermodal Representationalism
    American Philosophical Quarterly 54 (3): 251-268. 2017.
    Intermodal representationalists hold that the phenomenal characters of experiences are fully determined by their contents. In contrast, intramodal representationalists hold that the phenomenal characters of experiences are determined by their contents together with their intentional modes or manners of representation, which are nonrepresentational features corresponding roughly to the sensory modalities. This paper discusses a kind of experience that provides evidence for an intermodal represent…Read more

    Consciousness and Intentionality
    In Uriah Kriegel (ed.), Oxford Handbook of Philosophy of Consciousness, Oxford University Press. forthcoming.
    Philosophers traditionally recognize two main features of mental states: intentionality and phenomenal consciousness. To a first approximation, intentionality is the aboutness of mental states, and phenomenal consciousness is the felt, experiential, qualitative, or "what it'€™s like" aspect of mental states. In the past few decades, these features have been widely assumed to be distinct and independent. But several philosophers have recently challenged this assumption, arguing that intentionalit…Read more

    The rational role of experience
    Inquiry: An Interdisciplinary Journal of Philosophy 61 (5-6): 467-493. 2018.
    If there is content that we reason on, cognitive content, it is in the head and accessible to reasoning mechanisms. This paper discusses the phenomenal theory of cognitive content, according to which cognitive contents are the contents of phenomenal consciousness. I begin by distinguishing cognitive content from the closely associated notion of narrow content. I then argue, drawing on prior work, that the phenomenal theory can plausibly account for the cognitive contents of many relatively simpl…Read more

    We can classify theories of consciousness along two dimensions. First, a theory might be physicalist or dualist. Second, a theory might endorse any of these three views regarding causal relations between phenomenal properties (properties that characterize states of our consciousness) and physical properties: nomism (the two kinds of property interact through deterministic laws), acausalism (they do not causally interact), and anomalism (they interact but not through deterministic laws). In this …Read more

    Quantum leaps in philosophy of mind
    Journal of Consciousness Studies 11 (12): 17--42. 2004.
    I discuss the quantum mechanical theory of consciousness and freewill offered by Stapp (1993, 1995, 2000, 2004). First I show that decoherence-based arguments do not work against this theory. Then discuss a number of problems with the theory: Stapp's separate accounts of consciousness and freewill are incompatible, the interpretations of QM they are tied to are questionable, the Zeno effect could not enable freewill as he suggests because weakness of will would then be ubiquitous, and the holism…Read more

    Tracking Representationalism
    In Andrew Bailey (ed.), Philosophy of Mind: The Key Thinkers, Continuum. pp. 209-235. 2014.
    This paper overviews the current status of debates on tracking representationalism, the view that phenomenal consciousness is a matter of tracking features of one's environment in a certain way. We overview the main arguments for the view and the main objections and challenges it faces. We close with a discussion of alternative versions of representationalism that might overcome the shortcomings of tracking representationalism

    This paper compares tracking and phenomenal intentionality theories of intentionality with respect to the issue of naturalism. Tracking theories explicitly aim to naturalize intentionality, while phenomenal intentionality theories generally do not. It might seem that considerations of naturalism count in favor of tracking theories. We survey key considerations relevant to this claim, including some motivations for and objections to the two kinds of theories. We conclude by suggesting that natura…Read more

    Intensional Perceptual Ascriptions
    Erkenntnis 82 (3): 513-530. 2017.
    This paper defends the view that perceptual ascriptions such as “Jones sees a cat” are sometimes intensional. I offer a range of examples of intensional perceptual ascriptions, respond to objections to intensional readings of perceptual ascriptions, and show how widely accepted semantic accounts of intensionality can explain the key features of intensional perceptual ascriptions.

    The representational theory of consciousness
    Dissertation, Australian National University. 2010.
    A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model which specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. One of the main difficulties with consciousness is that we lack a language in which to formulate …Read more

    The Role of Consciousness in Grasping and Understanding
    Philosophy and Phenomenological Research 95 (2): 285-318. 2017.
    One sometimes believes a proposition without grasping it. For example, a complete achromat might believe that ripe tomatoes are red without grasping this proposition. My aim in this paper is to shed light on the difference between merely believing a proposition and grasping it. I focus on two possible theories of grasping: the inferential theory, which explains grasping in terms of inferential role, and the phenomenal theory, which explains grasping in terms of phenomenal consciousness. I argue …Read more

    Phenomenal Intentionality
    The Stanford Encyclopedia of Philosophy. 2016.
    Phenomenal intentionality is a kind of intentionality, or aboutness, that is grounded in phenomenal consciousness, the subjective, experiential feature of certain mental states. The phenomenal intentionality theory (PIT), is a theory of intentionality according to which there is phenomenal intentionality, and all other kinds of intentionality at least partly derive from it. In recent years, PIT has increasingly been seen as one of the main approaches to intentionality.

    One central brand of representationalism claims that the specific phenomenal character of an experience is fully determined by its content. A challenge for this view is that cognitive and perceptual experiences sometimes seem to have the same representational content while differing in phenomenal character. In particular, it might seem that one can have faint imagery experiences or conscious thoughts with the same contents as vivid perceptual experiences. This paper argues that such cases never …Read more

    Representationalism, perceptual distortion and the limits of phenomenal concepts
    Canadian Journal of Philosophy 45 (1): 16-36. 2015.
    This paper replies to objections from perceptual distortion against the representationalist thesis that the phenomenal characters of experiences supervene on their intentional contents. It has been argued that some pairs of distorted and undistorted experiences share contents without sharing phenomenal characters, which is incompatible with the supervenience thesis. In reply, I suggest that such cases are not counterexamples to the representationalist thesis because the contents of distorted exp…Read more

    What do philosophers believe?
    Philosophical Studies 170 (3): 465-500. 2014.
    What are the philosophical views of contemporary professional philosophers? We surveyed many professional philosophers in order to help determine their views on 30 central philosophical issues. This article documents the results. It also reveals correlations among philosophical views and between these views and factors such as age, gender, and nationality. A factor analysis suggests that an individual's views on these issues factor into a few underlying components that predict much of the variat…Read more

    Representationalists argue that phenomenal states are intentional states of a special kind. This paper offers an account of the kind of intentional state phenomenal states are: I argue that they are underived intentional states. This account of phenomenal states is equivalent to two theses: first, all possible phenomenal states are underived intentional states; second, all possible underived intentional states are phenomenal states. I clarify these claims and argue for each of them. I also addre…Read more
