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 perceptual demonstration in being non-causal. DA nicely explains key intuitions about phenomenal self-knowledge, makes possible an appealing diagnosis of blindsight cases, and yields a highly plausible view as to the extent of our first-person epistemic privilege. Because these virtues stem from construing phenomenal properties as non-relational features of states, my defense of DA constitutes a challenge to relational construals of phenomenal properties, including functionalism and representationalism. And I provide reason to doubt that they can meet this challenge

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 issues reflecting ‘what matters to humans’, such as knowledge of one’s own character and the moral significance of self-knowledge. Cassam also contributes to this field: he advances an inferentialist account of self-knowledge and a moderate instrumentalism about self-knowledge’s value.

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. Tyes strategy differs crucially from the claim that identities never stand in need of explanation because they constitute ultimate explanations; for he allows that identities such as water = H?O are explainable. Unlike WATER and H?O, which are descriptive concepts, phenomenal concepts are perspectival and hence irreducible to descriptive concepts, according to Tye. The fact that something picked out by a perspectival concept is identical to something picked out by a non-perspectival concept cannot be explained.1 So, he concludes, phenomenalphysical identities need not be explained

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 is some salient epistemic difference between (a) one’s belief that she thinks it will rain tomorrow, or that she has a headache, and (b) her belief that it is raining, or that another person has a headache.

_Arguing About the Mind_ is an accessible, engaging introduction to the core questions in the philosophy of mind. This collection offers a selection of thought-provoking articles that examine a broad range of issues from the mind and body relation to animal and artificial intelligence. Topics addressed include: the problem of consciousness; the nature of the mind; the relationship between the mind, body and world; the notion of selfhood; pathologies and behavioural problems; animal, machine and extra-terrestrial intelligence. The editors provide lucid introductions to each section, give an overview of the debate and outline the arguments of the papers. An original and stimulating reader, _Arguing About the Mind_ is ideal for students new to the philosophy of mind.

In self-attributing beliefs and desires, we exploit a method that is different from our methods for attributing such states to others. On one traditional diagnosis, this difference stems from the subject’s exclusive access to introspective evidence. Gallois rejects the “access to evidence” model of the epistemic difference between self-knowledge and other-knowledge; in this ambitious book he provides a non-introspectivist alternative account of first-person authority. His intriguing proposal is that rational subjects can know their consciously held propositional attitudes without observing their own states. While he allows that we sometimes have introspective evidence for our own propositional attitudes, he is deeply suspicious about the power often accorded to such evidence. Robust conceptions of rationality and state consciousness weigh heavily in Gallois’ arguments and, I think, threaten to trivialize his claim that we enjoy first-person authority. But by departing from introspectivist accounts of self-knowledge, Gallois has made a provocative opening move in a gambit which promises to advance our understanding of the epistemic difference between self-knowledge and other-knowledge.

"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 agreement about what precisely distinguishes self-knowledge from knowledge in other realms. Partially because of this disagreement, philosophers have endorsed competing accounts of how we acquire self-knowledge. These accounts have important consequences for the scope of mental content, for mental ontology, and for personal identity.

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-knowledge, our capacity for self-knowledge derives from our rational agency—our ability to conform our attitudes to our reasons, and to commit ourselves to those attitudes through avowals. This paper has two goals. The first is exegetical: to identify agentialism's defining thesis and precisely formulate the agentialist challenge to empiricism. The second goal is to defend empiricism from the agentialist challenge. I propose a way to understand the role of agency in reasoning and avowals, one that does justice to what is distinctive about these phenomena yet is compatible with empiricism about self-knowledge

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 focusing on Jackson’s argument, though I will also describe the main points of alleged similarity and dissimilarity between these two arguments.

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 detailed picture of the approach emerges in succeeding sections, which respond to a range of objections. Some critics charge that approaches of this sort are overly idealized, in that they ignore the cognitive flaws and limitations of actual human beings. I begin to address these worries in Section 2, by arguing that the epistemic commitments of the acquaintance approach are in fact relatively modest. In Section 3, I sketch a picture of introspective reference that explains how phenomenal reality can intersect with the epistemic in a phenomenal judgment, as the acquaintance approach requires. Drawing on this picture of introspective reference, Section 4 sets out a practical strategy for achieving knowledge by acquaintance. Some contemporary acquaintance theorists (BonJour 2003, Fumerton 1996) employ demanding epistemic standards for knowledge by acquaintance, standards beyond those mandated by the acquaintance approach. In Section 5 I show that instances of introspective knowledge that meet less demanding standards can satisfy the acquaintance approach’s epistemic commitments. The final sections concern the most direct challenges to the acquaintance approach, which target the claim that phenomenal reality intersects with the epistemic. According to one such challenge, this claim is belied by the fact that possessing a phenomenal concept is a matter of having certain dispositions. Section 6 draws on a discussion by Sosa (2003) to articulate this challenge, and responds to it on behalf of the acquaintance approach. Section 7 addresses Stalnaker’s (2008) worry that, if phenomenal reality intersected with the epistemic, phenomenal information would be incommunicable.

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. Materialist reduction of the phenomenal is, thus, untenable; materialists must adopt a more extreme, eliminativist view about the phenomenal
