I will present a conceptual argument for a simulationist answer to (2). Given that our conception of mental states is employed in attributing mental states to others, a simulationist answer to (2) supports a simulationist answer to (1). I will not address question (3). Answers to (1) and (2) do not yield an answer to (3), since (1) and (2) concern only our actual practices and concepts. For instance, an error theory about (1) and (2) would say that our practices and concepts manifest a mistaken view about the real nature of the mental. Finally, I will not address question (2a), which is an empirical question and so is not immediately relevant to the conceptual argument that is of concern here

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 the individual and her community, and the epistemic availability of thoughts. This situation stems from the fact that contributors to debates about externalism differ in how they understand 'internal property'; these differences reveal (or, perhaps, generate) disparate conceptions of what is at issue in these debates. I argue that this situation is irremediable. There is no way to understand 'internal property' that will conform with prevailing beliefs about the nature of internalism and externalism, and with the usual taxonomy of leading positions. This ambiguity carries a heavy price: participants in these debates often argue at cross-purposes, disagreeing even on the nature of the evidence that could settle the question of externalism. Progress on the broad range of issues associated with these debates requires that we abandon the categories 'internalism' and 'externalism'. I close by suggesting a promising avenue for future research related to these issues.

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 causally related to introspected thoughts, the disparity between self-knowledge and other-knowledge is not truly principled. An account of self-knowledge adequate to a truly principled disparity will allow that thought tokens can be.

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 gloss, to refer to any method of knowing one’s own mental states, and not just self-directed attention. But the more restrictive use is standard, and provides the topic of the current entry.) As we will see, some contemporary philosophers and psychologists doubt that any such introspective process underlies self-knowledge.

My dissertation has three interrelated aims: to defend introspectivism, the view that the deliverances of introspection should be basic data for philosophical theories of the mind, from pivotal objections which inspire the currently prevailing anti-introspectivist approach to mentality; to advance a substantive account of introspection; and to lay the groundwork for a more general theory about the mental. ;I begin by analyzing a host of philosophical problems about the mind; in each, I isolate the source of perplexity in an epistemic factor. The body of the thesis is devoted to elucidating the ontological and epistemological status of mind by considering, in turn, phenomenality and intentionality. ;Physicalism lacks the resources to explain the individual subject's greater epistemic authority regarding the phenomenal as compared to the physical. My detailed account of phenomenal state introspection is therefore preferable to the physicalist explanations of phenomenal knowledge; its consequences include a counterexample to a widely-accepted constraint on concept possession and a minor modification to one familiar theory of de se reference. ;Similarly, functionalist reduction of intentional states cannot countenance our refusal to defer to empirical science regarding one's occurrent mental states to the same extent that we defer regarding physical states. My account of introspection, which does justice to the measure of authority we retain about our own intentional states, undermines both functionalism and content externalism about such states. ;Grave difficulties face each of the four currently popular views about the relation between phenomenality and intentionality. According to my alternative, occurrent phenomenal states and occurrent intentional states are importantly different yet share an epistemic feature which distinguishes them from physical states: our deference to empirical science regarding such occurrent states is limited in a way that our deference regarding physical states is not. The key to understanding the mind is thus intimately related to the primary source of philosophical problems about it, namely, the disparity between our knowledge of the mental and our knowledge of the physical

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 causation. I show that those who endorse the acquaintance response face special obstacles to invoking parsimony in an argument for physicalism. And I show how acknowledging the phenomenon of acquaintance can ease the dualist’s problems with mental causation, by dispelling three key objections to epiphenomenalism. The most challenging of these objections is that epiphenomenalism blocks an evolutionary explanation of the so-called “hedonic/utility match”. I propose that pleasures and pains, while themselves epiphenomenal, can nonetheless explain positive and negative associations with stimuli, associations that can contribute to fitness.

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 the best alternative for those who remain skeptical about the existence – or, perhaps, even the possibility – of extended minds

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 arguments and raise some questions about her proposed criterion for "mental".

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 body, which are attracted and repelled by certain electrons and protons in the thing you think you are touching, but there is no actual contact. … The electrons and protons themselves, however, are only crude first approximations, a way of collecting into a bundle either trains of waves or the statistical probabilities of various different kinds of events. Thus matter has become altogether too ghostly to be used as an adequate stick with which to beat the mind. —Bertrand Russell, “What is the Soul?” 193..

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 between self-knowledge and self-awareness and providing essential historical background to the problem, Gertler addresses specific theories of self-knowledge such as the acquaintance theory, the inner sense theory, and the rationalist theory, as well as leading accounts of self-awareness. The book concludes with a critical explication of the dispute between empiricist and rationalist approaches
