    Externalism about mental content is now widely accepted. It is therefore surprising that there is no established definition of externalism. I believe that this is a symptom of an unrecognized fact: that the labels 'mental content externalism' -- and its complement 'mental content internalism' -- are profoundly ambiguous. Under each of these labels falls a hodgepodge of sometimes conflicting claims about the organism's contribution to thought contents, the nature of the self, relations between th…Read more

    Self‐Knowledge and Rational Agency: A Defense of Empiricism
    Philosophy and Phenomenological Research 96 (1): 91-109. 2018.
    How does one know one's own beliefs, intentions, and other attitudes? Many responses to this question are broadly empiricist, in that they take self-knowledge to be epistemically based in empirical justification or warrant. Empiricism about self-knowledge faces an influential objection: that it portrays us as mere observers of a passing cognitive show, and neglects the fact that believing and intending are things we do, for reasons. According to the competing, agentialist conception of self-know…Read more

    Renewed Acquaintance
    In Declan Smithies & Daniel Stoljar (eds.), Introspection and Consciousness, Oxford University Press. pp. 89-123. 2012.
    I elaborate and defend a set of metaphysical and epistemic claims that comprise what I call the acquaintance approach to introspective knowledge of the phenomenal qualities of experience. The hallmark of this approach is the thesis that, in some introspective judgments about experience, (phenomenal) reality intersects with the epistemic, that is, with the subject’s grasp of that reality. In Section 1 of the paper I outline the acquaintance approach by drawing on its Russellian lineage. A more de…Read more

    The definitive statement of the Knowledge Argument was formulated by Frank Jackson, in a paper entitled “Epiphenomenal Qualia” that appeared in The Philosophical Quarterly in 1982. Arguments in the same spirit had appeared earlier (Broad 1925, Robinson 1982), but Jackson’s argument is most often compared with Thomas Nagel’s argument in “What is it Like to be a Bat?” (1974). Jackson, however, takes pains to distinguish his argument from Nagel’s. This entry will follow standard practice in focusin…Read more

    Self-Knowledge for Humans, by Quassim Cassam (review)
    Mind 125 (497): 269-280. 2016.
    With this provocative book, Quassim Cassam aspires to reorient the philosophical study of self-knowledge so as to bring its methodology and subject matter into line with recognizably human concerns. He pursues this reorientation on two fronts. He proposes replacing what he sees as the field’s standard subject, an ideally rational being he calls Homo Philosophicus, with a more realistic Homo Sapiens. And he proposes shifting the field’s primary focus from ‘narrow epistemological concerns’ to issu…Read more

    Self-Knowledge and the Transparency of Belief
    In Anthony Hatzimoysis (ed.), Self-Knowledge, Oxford University Press. 2008.
    In this paper, I argue that the method of transparency --determining whether I believe that p by considering whether p -- does not explain our privileged access to our own beliefs. Looking outward to determine whether one believes that p leads to the formation of a judgment about whether p, which one can then self-attribute. But use of this process does not constitute genuine privileged access to whether one judges that p. And looking outward will not provide for access to dispositional beliefs,…Read more

    A primary goal of this chapter is to highlight neglected epistemic parallels between dualism and physicalism. Both dualist and physicalist arguments employ a combination of empirical data and armchair reflection; both rely on considerations stemming from how we conceptualize certain phenomena; and both aim to establish views that are compatible with scientific results but go well beyond the deliverances of empirical science. I begin the chapter by fleshing out the distinctive commitments of dual…Read more

    Overextending the mind
    In Brie Gertler & Lawrence Shapiro (eds.), Arguing About the Mind, Routledge. pp. 192--206. 2007.
    Clark and Chalmers argue that the mind is extended – that is, its boundary lies beyond the skin. In this essay, I will criticize this conclusion. However, I will also defend some of the more controversial elements of Clark and Chalmers's argument. I reject their conclusion because I think that their argument shows that a seemingly innocuous assumption, about internal states and processes, is flawed. My goal is not to conclusively refute Clark and Chalmers's conclusion. My aim is only to reveal t…Read more

    Self-Knowledge
    Stanford Encyclopedia of Philosophy. 2015.
    "Self-knowledge" is commonly used in philosophy to refer to knowledge of one's particular mental states, including one's beliefs, desires, and sensations. It is also sometimes used to refer to knowledge about a persisting self -- its ontological nature, identity conditions, or character traits. At least since Descartes, most philosophers have believed that self-knowledge is importantly different from knowledge of the world external to oneself, including others' thoughts. But there is little agre…Read more

    Acquaintance, Parsimony, and Epiphenomenalism
    In Sam Coleman (ed.), The Knowledge Argument, Cambridge University Press. pp. 62-86. 2019.
    Some physicalists (Balog 2012, Howell 2013), and most dualists, endorse the acquaintance response to the Knowledge Argument. This is the claim that Mary gains substantial new knowledge, upon leaving the room, because phenomenal knowledge requires direct acquaintance with phenomenal properties. The acquaintance response is an especially promising way to make sense of the Mary case. I argue that it casts doubt on two claims often made on behalf of physicalism, regarding parsimony and mental causat…Read more

    Rational Agency and the Struggle to Believe What Your Reasons Dictate
    In Cristina Borgoni, Dirk Kindermann & Andrea Onofri (eds.), The Fragmented Mind, Oxford University Press. 2021.
    According to an influential view that I call agentialism, our capacity to believe and intend directly on the basis of reasons—our rational agency—has a normative significance that distinguishes it from other kinds of agency (Bilgrami 2006, Boyle 2011, Burge 1996, Korsgaard 1996, Moran 2001). Agentialists maintain that insofar as we exercise rational agency, we bear a special kind of responsibility for our beliefs and intentions; and it is only those attitudes that represent the exercise of ratio…Read more

    The claim that there is an explanatory gap between physical and phenomenal properties is perhaps the leading current challenge to materialist views about the mind. Tye tries to block this challenge, not by providing an explanation to bridge the gap but by denying that phenomenalphysical identities introduce an explanatory gap. Since an explanatory gap exists only if there is something unexplained that needs explaining, and something needs explaining only if it can be explained , there is no gap.…Read more

    Self-Knowledge
    Routledge. 2010.
    The problem of self-knowledge is one of the most fascinating in all of philosophy and has crucial significance for the philosophy of mind and epistemology. Gertler assesses the leading theoretical approaches to self-knowledge, explaining the work of many of the key figures in the field: from Descartes and Kant, through to Bertrand Russell and Gareth Evans, as well as recent work by Tyler Burge, David Chalmers, William Lycan and Sydney Shoemaker. -/- Beginning with an outline of the distinction b…Read more

    This chapter concerns self-knowledge of our mental states, with a focus on how we know our own beliefs and intentions. It examines the agentialist approach to self-knowledge, which is driven by the idea that believing or intending on the basis of reasons is something that we DO, and hence involves agency. Agentialists maintain that, because beliefs and intentions are exercises of agency, self-knowledge of these attitudes differs fundamentally from self-knowledge of states that we simply undergo,…Read more

    A defense of the knowledge argument
    Philosophical Studies 93 (3): 317-336. 1999.
    This paper calls into question the viability of materialist reduction of the phenomenal. I revisit the 'Knowledge Argument', which claims that there is information about the phenomenal which is not reducible to, nor even inferable from, information about the physical. I demonstrate the failure of the two chief strategies for blocking the Knowledge Argument: analyzing phenomenal knowledge as an ability, and construing it as knowledge of facts which are ontologically reducible to physical facts. M…Read more

    My aim here is threefold: to show that conceptual facts play a more significant role in justifying explanatory reductions than most of the contributors to the current debate realize; to furnish an account of that role, and to trace the consequences of this account for conceivability arguments about the mind

    When read as demands for justification, these questions seem absurd. We don’t normally ask people to substantiate assertions like “I think it will rain tomorrow” or “I have a headache”. There is, at the very least, a strong presumption that sincere self-attributions about one’s thoughts and feelings are true. In fact, some philosophers believe that such self-attributions are less susceptible to doubt than any other claims. Even those who reject that extreme view generally acknowledge that there …Read more

    Goldberg (2003) defends externalism from Boghossian's (1998) version of the "armchair knowledge" objection. I argue here that, while Goldberg's challenge blocks a different version of this objection, it does not directly block Boghossian's version. And Goldberg's approach is not promising as a response to Boghossian's version of the armchair knowledge objection.

    Introspecting phenomenal states
    Philosophy and Phenomenological Research 63 (2): 305-28. 2001.
    This paper defends a novel account of how we introspect phenomenal states, the Demonstrative Attention account (DA). First, I present a set of necessary and sufficient conditions for phenomenal state introspection which are not psychological, but purely metaphysical and semantic. Next, to explain how these conditions can be satisfied, I describe how demonstrative reference to a phenomenal content can be achieved through attention alone. This sort of introspective demonstration differs from perce…Read more

    Smithies on Self-Knowledge of Beliefs
    Analysis 81 (4): 782-792. 2022.
    This commentary focuses on Smithies’ views about self-knowledge. Specifically, I examine his case for the striking thesis that rational thinkers will know all their beliefs. I call this the ubiquity of self-knowledge thesis. Smithies’ case for this thesis is an important pillar of his larger project, as it bears on the nature of justification and our ability to fulfill the requirements of rationality. Section 1 outlines Smithies’ argument for the ubiquity of self-knowledge. Section 2 sets the s…Read more

    Introspection
    In Patrick Wilken, Timothy J. Bayne & Axel Cleeremans (eds.), The Oxford Companion to Consciousness, Oxford University Press. pp. 76-111. 2009.
    Alas, things are not quite so simple. As James implies, the term ‘introspection’ literally means ‘looking within’, but of course we do not visually inspect the interiors of our crania. What unites proponents of introspection is the claim that we can recognize our own mental states through some sort of attention—a non-visual ‘looking’—whose immediate objects are thoughts or sensations within oneself, in a non-spatial sense of ‘within’. (The term ‘introspection’ is occasionally given an ecumenical…Read more

    The mechanics of self-knowledge
    Philosophical Topics 28 (2): 125-46. 2000.
    It is often said that we can know our own thoughts more directly or with more certainty than anyone else can know them. And this disparity is usually taken to be principled, in that we would not be the rational, reflective beings that we are without it. My aim is to trace the consequences of a principled disparity between self-knowledge and other-knowledge for what may be termed the “mechanics ” of self-knowledge . I use a new thought experiment to show that if introspective states are merely ca…Read more

    The relationship between phenomenality and intentionality: Comments on Siewert's The Significance of Consciousness
    PSYCHE: An Interdisciplinary Journal of Research On Consciousness 7. 2001.
    Charles Siewert offers a persuasive argument to show that the presence of certain phenomenal features logically suffices for the presence of certain intentional ones. He claims that this shows that phenomenal features are inherently intentional. I argue that he has not established the latter thesis, even if we grant the logical sufficiency claim. For he has not ruled out a rival alternative interpretation of the relevant data, namely, that intentional features are inherently phenomenal

    The subject's point of view – Katalin Farkas (review)
    Philosophical Quarterly 59 (237): 743-747. 2009.
    Farkas’ ambitious agenda is to advance a strongly internalist account of the mental. She makes impressive strides towards achieving this goal. Along the way, she presents important new arguments on a number of topics, including: how best to understand the ‘twin’ cases used in debates about content, the alleged incompatibility of content externalism and privileged access, and the prospects for defending Frege’s claim that sense determines reference. In this review, I survey a number of her argume…Read more

    The plain man thinks that material objects must certainly exist, since they are evident to the senses. Whatever else may be doubted, it is certain that anything you can bump into must be real; this is the plain man’s metaphysic. This is all very well, but the physicist comes along and shows that you never bump into anything: even when you run your hand along a stone wall, you do not really touch it. When you think you touch a thing, there are certain electrons and protons, forming part of your b…Read more

    Can feminists be cartesians?
    Dialogue 41 (1): 91-112. 2002.
    I defend one leading strand of Descartes's thought against feminist criticism. I will show that Descartes's “first-person” approach to our knowledge of minds, which has been criticized on feminist grounds, is at least compatible with key feminist views. My argument suggests that this strand of Cartesianism may even bolster some central feminist positions.
