Functionalism in the philosophy of mind is the doctrine that what makes something a mental state of a particular type does not depend on its internal constitution, but rather on the way it functions, or the role it plays, in the system of which it is a part. This doctrine is rooted in Aristotle's conception of the soul, and has antecedents in Hobbes's conception of the mind as a “calculating machine”, but it has become fully articulated (and popularly endorsed) only (...) in the last third of the 20th century. Though the term ‘functionalism’ is used to designate a variety of positions in a variety of other disciplines, including psychology, sociology, economics, and architecture, this entry focuses exclusively on functionalism as a philosophical thesis about the nature of mental states.

Defenders of pragmatic theories of knowledge (such as contextualism and sensitive invariantism) argue that these theories, unlike those that invoke a single standard for knowledge, comport with the intuitively compelling thesis that knowledge is the norm of assertion and practical reason. In this paper, I dispute this thesis, and argue that, therefore, the prospects for both “high standard” approach, and contend that if one abandons the thesis that knowledge is the norm of assertion and practical reason, the most serious arguments (...) against it lose force.

Philosophers have traditionally held that claims about necessities and possibilities are to be evaluated by consulting our philosophical intuitions; that is, those peculiarly compelling deliverances about possibilities that arise from a serious and reflective attempt to conceive of counterexamples to these claims. But many contemporary philosophers, particularly naturalists, argue that intuitions of this sort are unreliable, citing examples of once-intuitive, but now abandoned, philosophical theses, as well as recent psychological studies that seem to establish the general fallibility of intuition.In the (...) first two sections of this paper, I evaluate these arguments, and also the counter-arguments of contemporary defenders of tradition. In the next two sections, I sketch an alternative account of the role of philosophical intuitions that incorporates elements of traditionalism and naturalism - and defend it against other such views. In the final section, however, I discuss intuitions about conscious experience, and acknowledge that my view may not extend comfortably to this case. This may seem unfortunate, since so much contemporary discussion of the epistemology of modality seems motivated by worries about the mind-body problem, and informed by the position one wishes to endorse. But, as I argue, if conscious experience is indeed an exception to the view I suggest in this paper, it is an exception that proves - and can illuminate - the rule. (shrink)

ABSTRACTType B, or a posteriori, physicalism is the view that phenomenal-physical identity statements can be necessarily true, even though they cannot be known a priori—and that the key to understanding their status is to understand the special features of our phenomenal concepts, those concepts of our experiential states acquired through introspection. This view was once regarded as a promising response to anti-physicalist arguments that maintain that an epistemic gap between phenomenal and physical concepts entails that phenomenal and physical properties are (...) distinct. More recently, however, many physicalists have lost confidence in the view, and have proposed less promising defences of physicalism—or have become outright sceptical about its prospects. I argue here that these physicalists have underestimated the resources of Type B physicalism and are thereby retreating too quickly—or fighting battles that have already been won. (shrink)

In this paper I discuss the claim that the successful reduction of qualitative to physical states requires some sort of intelligible connection between our qualitative and physical concepts, which in turn requires a conceptual analysis of our qualitative concepts in causal-functional terms. While I defend this claim against some of its recent critics, I ultimately dispute it, and propose a different way to get the requisite intelligible connection between qualitative and physical concepts.

Molyneux's Question, that is, “Suppose a man born blind, and now adult, and taught by his touch to distinguish between a cube and a sphere... and the blind man made to see: Quaere, whether by his sight, before he touched them, he could now distinguish, and tell, which is the globe, which the cube”, was discussed by many theorists in the 17th and 18th centuries, and has recently been addressed by contemporary philosophers interested in the nature, and identity conditions, of (...) perceptual concepts. My main concern in this paper is to argue – against Evans, Campbell, and a number of other contemporary philosophers – that a test of the sort Molyneux envisioned, at least if carefully designed and administered, can indeed be a crucial experiment for the claim that we deploy the same perceptual concepts when identifying shapes by sight and by touch. I will explore some implications of this argument for a theory of recognitional concepts. And I’ll try to trace out some unhappy consequences of various alternative views. (shrink)

It is standard practice in philosophical inquiry to test a general thesis (of the form 'F iff G' or 'F only if G') by attempting to construct a counterexample to it. If we can imagine or conceive of1an F that isn't a G, then we have evidence that there could be an F that isn't a G — and thus evidence against the thesis in question; if not, then the thesis is (at least temporarily) secure. Or so it is standardly (...) claimed.But there is increasing skepticism about how seriously to take what we can imagine or conceive as evidence for (or against) a priori philosophical theses, given the many historical examples of now-questionable theses that once seemed impossible to doubt — and also the recent experimental research ..

Abstract: Type-B materialism is the thesis that though phenomenal states are necessarily identical with physical states, phenomenal concepts have no a priori connections to physical or functional concepts. Though type-B materialists have invoked this conceptual independence to counter a number of well-known arguments against physicalism (e.g. the conceivability of zombies, the ignorance of Mary, the existence of an 'explanatory gap'), anti-physicalists have raised objections to this strategy. My aim here is to defend type-B materialism against these objections, by arguing that (...) they share the common problem of not taking the central features of the view sufficiently seriously. However, I will end by noting that type-B materialism raises other questions, and suggesting that what stands in the way of an adequate naturalistic account of phenomenal states may be the propensity to take type-B materialism more seriously than it deserves.

In a footnote to his ‘What is it Like to be a Bat?’, Thomas Nagel sketches a promising account of phenomenal concepts that purports to explain why mind-body identity statements, even if necessary, will always seem contingent. Christopher Hill and Brian McLaughlin have recently developed this sketch into a more robust theory. In Nagel's more recent work, however, he suggests that the only adequate theory of phenomenal concepts is one that makes the relation between phenomenal and physical states intelligible, or (...) ‘transparent’. Developing such a theory, however, appears to be no easy task. In this paper I argue that the Nagel-Hill-McLaughlin proposal is preferable – and that a serious problem with it, noticed by Stephen Yablo, can be avoided by revising the proposal according to some further suggestions made by Nagel himself.

Levin argues that the results of the most methodologically sound and philosophically relevant studies discussed in this volume [ Experimental Philosophy] could have been obtained from the armchair, and thus that experimental philosophy may not present a serious challenge to the traditional methods of analytic philosophy.

This paper challenges some leading views about the conditions under which the ascription of beliefs and desires can make sense of, or provide reasons for, a creature's behavior. I argue that it is unnecessary for behavior to proceed from beliefs and desires according to the principles of logic and decision theory, or even from principles that generally get things right. I also deny that it is necessary for behavior to proceed from principles that, though perhaps subrational, are similar to those (...) that we ourselves use. I then propose some conditions that are considerably weaker, and argue that they fulfill the descriptive and explanatory requirements of intentional ascription. (shrink)

In this thoughtful, rich, and extremely ambitious book, Norton Nelkin develops a "Scientific Cartesian" theory of sensation and perception, consciousness, conceptual content, and concept formation. The theory is Cartesian primarily because its account of mental states is realist, individualist, and internalist; Nelkin also holds, with Descartes, that perceptions are spontaneous judgments and that at least some of our concepts are innate. But, unlike Descartes, Nelkin rejects dualism and treats the mind as something that can be studied by the same methods (...) as other natural phenomena; indeed, Nelkin goes further than many contemporary theorists in attempting to make his views consistent with, and informed by, studies in the cognitive sciences.

A recent study published in Nature Neuroscience purports to have answered a question posed to Locke in 1688 by his friend William Molyneux, namely, whether ‘a man born blind and made to see’ would be able to identify, immediately and by vision alone, objects previously known only by touch. The answer, according to the researchers – and as predicted by Molyneux, as well as Locke, Berkeley, and others – is ‘likely negative. The newly sighted subjects did not exhibit an immediate (...) transfer of their tactile shape knowledge to the visual domain’. Since then, however, many commentators have argued that the answer is still not clear. Moreover, in the contemporary literature on Molyneux’s Question, and more generally on cross-modal perception and the individuation of the senses, it is sometimes hard to determine what question is being investigated. In this paper, I distinguish a number of different questions about the relation between visual and tactual perception that can arise when considering Molyneux’s... (shrink)

The study of perception and the role of the senses have recently risen to prominence in philosophy and are now a major area of study and research. However, the philosophical history of the senses remains a relatively neglected subject. Moving beyond the current philosophical canon, this outstanding collection offers a wide-ranging and diverse philosophical exploration of the senses, from the classical period to the present day. Written by a team of international contributors, it is divided into six parts: -/- Perception (...) from Non-Western Perspectives Perception in the Ancient Period Perception in the Medieval Latin/Arabic Period Perception in the Early Modern Period Perception in the Post-Kantian Period Perception in the Contemporary Period. The volume challenges conventional philosophical study of perception by covering a wide range of significant, as well as hitherto overlooked, topics, such as perceptual judgment, temporal and motion illusions, mirror and picture perception, animal senses and cross-modal integration. By investigating the history of the senses in thinkers such as Plotinus, Auriol, Berkeley and Cavendish; and considering the history of the senses in diverse philosophical traditions, including Chinese, Indian, Byzantine, Greek and Latin it brings a fresh approach to studying the history of philosophy itself. -/- Including a thorough introduction as well as introductions to each section by the editors, The Senses and the History of Philosophy is essential reading for students and researchers in the history of philosophy, perception, philosophy of mind, philosophical psychology, aesthetics and eastern and non-western philosophy. It will also be extremely useful for those in related disciplines such as psychology, religion, sociology, intellectual history and cognitive sciences. (shrink)

In recent years, functionalism has emerged as the most appealing candidate for a materialistic theory of mind. Its central thesis - that types of mental states can be defined in terms of their causal and counterfactual relations to the sensory stimulations, other internal states, and behavior of the entities that have them - offers hope for a reasonable materialism: it promises type-identity conditions for beliefs, sensations, and emotions that are not irreducibly mental, yet would permit entities that are physically quite (...) different to be in mental states of the same type.

Many well-known arguments against physicalism—e.g., Chalmers’s Zombie Argument and Kripke’s Modal Argument—contend that it is conceivable for there to be physical duplicates of ourselves that have no conscious experiences (or, conversely, for there to be disembodied minds) and also that what is conceivable is possible—and therefore, if phenomenal-physical identity statements are supposed to be necessary, then physicalism can’t be true. Physicalists typically respond to these arguments either by questioning whether such creatures can truly be conceived, or denying that the conceivability (...) of such creatures provides good evidencefor their ‘metaphysical’ possibility. An increasing number of physicalists, however, contest these arguments in a different way, namely, by suggesting that the conceivability premises in these arguments beg the question: one’s ability to conceive of the existence of zombies (or disembodied minds) depends exclusively on what one antecedently believes to be the nature of conscious experience (or the theories of consciousness one tacitly accepts)—and therefore cannot legitimately be used to draw conclusions about whether conscious experiences could be physical states or processes. My aim in this paper is to consider, and raise questions about, (various versions of) this response to the antiphysicalist arguments—and argue that physicalists have more promising ways to disarm them.

In traditional armchair methodology, philosophers attempt to challenge a thesis of the form ‘F iff G’ or ‘F only if G’ by describing a scenario that elicits the intuition that what has been described is an F that isn’t G. If they succeed, then the judgment that there is, or could be, an F that is not G counts as good prima facie evidence against the target thesis. Moreover, if these intuitions remain compelling after further (good faith) reflection, then traditional (...) armchair methodology takes the judgment to be serious (though not infallible) evidence against the target thesis—call it secunda facie evidence—that should not be discounted as long as those intuitions retain their force. Some philosophers, however, suggest that this methodology is incompatible with epistemological naturalism, the view that philosophical inquiry should be sensitive to empirical observations, and argue that traditional armchair methodology must deemphasize the role of intuitions in philosophical inquiry. In my view, however, this would be a mistake: as I will argue, the most effective way to promote philosophical progress is to treat intuitions as having the (prima and secunda) evidential status I’ve described. But I will also argue that philosophical inquiry can produce a theory that is sensitive to empirical observations and the growth of empirical knowledge, even if it gives intuitions the prima- and secunda-facie evidential status that traditional armchair methodology demands—and thus that traditional armchair methodology, if properly practiced, need not be abandoned by naturalists, or even (except for a few exceptions) be much revised.

In "the subjective view", Colin mcginn contends that a dispositional (or "subjectivist") account of secondary qualities may be incompatible with physicalism, As it provides special reasons to think that the experiences of secondary qualities cannot be reduced to physical or functional states. The primary aim of this paper is to show that such an account of secondary qualities is compatible with--Indeed, Encourages--A physico-Functional theory of experience. Further, It argues that if secondary quality experiences cannot be reduced to physical or functional (...) states, Then the dispositional account of secondary qualities cannot hope to match the explanatory adequacy of a sophisticated reductionist view.

In Naming and Necessity, Kripke argues that clearly conceived (or imagined) scenarios that seem to be counterexamples to a posteriori identity theses can indeed count as evidence against them—but only if, after reflection on our understanding of their constituent terms and the relevant empirical facts, we find that they cannot be acceptably reconstrued as intuitions about something else. This makes trouble for phenomenalphysical identity statements such as ‘pain is C-fiber stimulation’, since most agree that such statements cannot be so reconstrued—and (...) thus some materialists reject Kripke’s account of the link between conceivability and possibility entirely. In my view, however, this is a mistake, since it impoverishes our resources for evaluating a posteriori modal claims;the better strategy for materialists is to show that phenomenal-physical identity statements comprise a special class of statements to which Kripke’s general strategy does not apply. In this paper I contribute to this project by examining, and challenging, Stephen Yablo’s (2005) general objections to Kripke’s strategy, and sketch a principled way to draw a distinction between phenomenal-physical identity statements and other a posteriori modal claims.

The Metaphysics of Mind presents and discusses the major contemporary theories of the nature of mind, including Dualism, Physicalism, Role-Functionalism, Russellian Monism, Panpsychism, and Eliminativism. Its primary goal is to examine the strengths and weaknesses of the theories in question, including their prospects for explaining the special qualitative character of sensations and perceptual experiences, the special outer-directedness of beliefs, desires, and other intentional states, and—more generally—the place of mind in the world of nature, and the relation between mental states and (...) the behaviors that they cause. It also discusses, briefly, some further questions about the metaphysics of mind, namely, whether groups of individuals, or entire communities, can possess mental states that cannot be reduced to the mental states of the individuals in those communities, and whether the boundaries between mind and world are as sharp as they may seem.

Many contemporary philosophers contend that a positive answer to Molyneux’s Question -- the question of whether a “man born blind and made to see” would be able to identify spatial figures, without touching them, on first viewing -- requires that there be a *rational connection* between the representations of those figures afforded by vision and by touch. This paper explores the question of what this could mean if the representations are non-discursive, or “pure recognitional” concepts, and argues that the most (...) plausible answer to this question can be invoked to resolve analogous questions about the individuation of phenomenal concepts.

In Naming and Necessity, Kripke argues that intuitions about what is possible play a limited, but important, role in challenging philosophical theses, counting as evidence against them only if they cannot be reconstrued as intuitions about something else, compatible with the thesis in question. But he doesn't provide clear guidelines for determining when such intuitions have been successfully reconstrued, leading some to question their status as evidence for modal claims. In this paper I focus on some worries, articulated by Michael (...) Della Rocca, about whether modal intuitions can be evidence for claims about essential properties, and argue that there is a way of viewing the role of modal intuition in philosophical argument that can preserve their evidential force.

Recently, a number of philosophers have argued that sensory images – “mental pictures” or other sense-based images of various situations – provide the best evidence for what is possible. In this paper I identify the best argument for this conclusion, but contend that it shows that certain non-sensory representations provide good evidence for possibility as well. That is, though I endorse the claim that the sensory imagination can be a source of evidence for what is possible, I deny that it (...) is the only source. I also sketch some consequences of this view for the thesis that sensations and perceptual experiences are identical to physical states. (shrink)
