First published in 1949, Gilbert Ryle ’s The Concept of Mind is one of the classics of twentieth-century philosophy. Described by Ryle as a ‘sustained piece of analytical hatchet-work’ on Cartesian dualism, The Concept of Mind is a radical and controversial attempt to jettison once and for all what Ryle called ‘the ghost in the machine’: Descartes’ argument that mind and body are two separate entities. This sixtieth anniversary edition includes a substantial commentary by Julia Tanney and is essential reading (...) for new readers interested not only in the history of analytic philosophy but in its power to challenge major currents in philosophy of mind and language today.

If we were to connect two individuals’ brains together, how would this affect the individuals’ conscious experiences? In particular, it is possible for two people to share any of their conscious experiences; to simultaneously enjoy some token experiences while remaining distinct subjects? The case of the Hogan twins—craniopagus conjoined twins whose brains are connected at the thalamus—seems to show that this can happen. I argue that while practical empirical methods cannot tell us directly whether or not the twins share conscious (...) experiences, considerations about the locality of content processing in the brain entails that they most likely do so.

There is widely assumed to be a fundamental epistemological asymmetry between self-knowledge and knowledge of others. They are said to be ’categorically different in kind and manner’ , and the existence of such an asymmetry is taken to be a primitive datum in accounts of the two kinds of knowledge. I argue that standard accounts of the differences between self-knowledge and knowledge of others exaggerate and misstate the asymmetry. The inferentialist challenge to the asymmetry focuses on the extent to which (...) both self-knowledge and knowledge of others are matters of inference and interpretation. In the case of self-knowledge I focus on the so-called ‘transparency method’ and on the extent to which use of this method delivers inferential self-knowledge. In the case of knowledge of others’ thoughts, I discuss the role of perception as a source of such knowledge and argue that even so-called ’perceptual’ knowledge of other minds is inferential. I contend that the difference between self-knowledge and knowledge of others is a difference in the kinds of evidence on which they are typically based. (shrink)

I focus on two questions: what is knowledge, and how is knowledge possible? The latter is an example of a how-possible question. I argue that how-possible questions are obstacle-dependent and that they need to be dealt with at three different levels, the level of means, of obstacle-removal, and of enabling conditions. At the first of these levels the possibility of knowledge is accounted for by identifying means of knowing, and I argue that the identification of such means also contributes to (...) a proper understanding of what knowledge is. (shrink)

An epistemological how-possible question asks how knowledge, or knowledge of some specific kind, is possible. Familiar epistemological how-possible questions include ‘How is knowledge of the external world possible?’, ‘How is knowledge of other minds possible?’ and ‘How is a priori knowledge possible?’ These are the three questions that I tackle in my book. In each case, I explain how and why the question arises and propose a way of answering it. The main negative claim of the book is that transcendental (...) arguments are of little use in answering how-possible questions. A transcendental demonstration of the necessity of a certain kind of knowledge does not amount to an explanation of its possibility. The main positive claim is that such questions call for what I describe as a multi-levels response. I give an account of the multi-levels approach and put it to use in explaining how various kinds of knowledge are possible.Epistemological how-possible questions are not directly concerned with whether knowledge is possible, but if we cannot explain how a certain kind of knowledge is possible then the reality of that kind of knowledge is called into question. How-possible questions are obstacle-dependent. We ask how knowledge …. (shrink)

I know various contingent truths about my environment by perception. For example, by looking, I know that there is a computer before me; by hearing, I know that someone is talking in the corridor; by tasting, I know that the coffee has no sugar. I know these things because I have some built-in mechanisms specialized for detecting the state of my environment. One of these mechanisms, for instance, is presently transducing electromagnetic radiation (in a narrow band of wavelengths) coming from (...) the computer and the desk on which it sits. How that mechanism works is a complicated story—to put it mildly—and of course much remains unknown. But we can at least produce more-or- less plausible sketches of how the mechanism can start from retinal irradiation, and go on to deliver knowledge of my surroundings. Moreover, in the sort of world we inhabit, specialized detection mechanisms that are causally affected by the things they detect have no serious competition—seeing the computer by seeing an idea of the computer in the divine mind, for example, is not a feasible alternative.

This paper argues that, given a certain apparently inevitable thesis about content, we could not know our own minds. The thesis is that the content of a thought is determined by its relational properties.

What is dignity? My starting point is that dignity is one of those philosophical primitives that admit of no informative analysis. Nonetheless, I suggest, dignity might yield to indirect illumination when we consider the kind of experience we have (or rather find it fitting to have) in its presence. This experience, I claim, is what is sometimes known as recognition-respect. Through an examination of a neglected aspect of the phenomenology of recognition-respect, I argue that the possession of inner consciousness is (...) a precondition for the possession of dignity. The reason for this, I suggest, is that the ultimate privacy of the contents of our consciousness grounds a kind of inviolability characteristic of dignity. (shrink)

Humans are not model epistemic citizens. Our reasoning can be careless, our beliefs eccentric, and our desires irrational. Quassim Cassam develops a new account of self-knowledge which recognises this feature of human life. He argues that self-knowledge is a genuine cognitive achievement, and that self-ignorance is almost always on the cards.

Since Socrates, and through Descartes to the present day, the problems of self-knowledge have been central to philosophy's understanding of itself. Today the idea of ''first-person authority''--the claim of a distinctive relation each person has toward his or her own mental life--has been challenged from a number of directions, to the point where many doubt the person bears any distinctive relation to his or her own mental life, let alone a privileged one. In Authority and Estrangement, Richard Moran argues for (...) a reconception of the first-person and its claims. Indeed, he writes, a more thorough repudiation of the idea of privileged inner observation leads to a deeper appreciation of the systematic differences between self-knowledge and the knowledge of others, differences that are both irreducible and constitutive of the very concept and life of the person. Masterfully blending philosophy of mind and moral psychology, Moran develops a view of self-knowledge that concentrates on the self as agent rather than spectator. He argues that while each person does speak for his own thought and feeling with a distinctive authority, that very authority is tied just as much to the disprivileging of the first-person, to its specific possibilities of alienation. Drawing on certain themes from Wittgenstein, Sartre, and others, the book explores the extent to which what we say about ourselves is a matter of discovery or of creation, the difficulties and limitations in being ''objective'' toward ourselves, and the conflicting demands of realism about oneself and responsibility for oneself. What emerges is a strikingly original and psychologically nuanced exploration of the contrasting ideals of relations to oneself and relations to others. (shrink)

This book explores a neglected philosophical question: How do groups of interacting minds relate to singular minds? Could several of us, by organizing ourselves the right way, constitute a single conscious mind that contains our minds as parts? And could each of us have been, all along, a group of mental parts in close cooperation? Scientific progress seems to be slowly revealing that all the different physical objects around us are, at root, just a matter of the right parts put (...) together in the right ways: How far could the same be true of minds? This book argues that we are too used to seeing the mind as an indivisible unity and that understanding our place in nature requires being willing to see minds as composite systems, simultaneously one conscious whole and many conscious parts. In thinking through the implications of such a shift of perspective, the book relates the question of mental combination to a range of different theories of the mind (in particular panpsychism, functionalism, and Neo-Lockeanism about personal identity) and identifies, clarifies, and addresses a wide array of philosophical objections (concerning personal identity, the unity of consciousness, the privacy of experience, and other issues) that have been raised against the idea of composite minds. The result is an account of the metaphysics of composition and consciousness that can illuminate many different debates in philosophy of mind, concerning split brains, collective intentionality, and the combination problem, among others.

Recent debates on phenomenal consciousness have shown renewed interest for the idea that experience generally includes an experience of the self – a self-experience – whatever else it may present the self with. When a subject has an ordinary experience (as of a bouncing red ball, for example), the thought goes, she is not just phenomenally aware of the world as being presented in a certain way (a bouncy, reddish, roundish way in this case); she is also phenomenally aware of (...) the fact that it is presented to her. This supposed phenomenal dimension has been variously called “mineness”, “for-me-ness”, “pre-reflective self-awareness” and “subjective character”, among others. This view, associated with historical figures such as William James, Husserl, Merleau-Ponty and Sartre, is attracting a new surge of attention at the crossroads of phenomenology, analytic philosophy of mind and the philosophy of cognitive science, but also intense controversy. This book explores some of the questions running through the ongoing debate on the putative subjective dimension of experience: Does it exist?, the existence question; What is it?, the essence question; What is it for?, the function question; and What else does it explain?, the explanation question. The volume also surveys various domains of human experience, both normal and pathological, where a “sense of self” might be at play, including agency, bodily awareness, introspection, memory, emotions and values, and offers insights into the possible relations between the notions of subjective awareness involved. The first part of the book is devoted to more sceptical or deflationary views about self-experience, and the second, to more robust ones. (shrink)

Direct Social Perception (DSP) is the idea that we can non-inferentially perceive others’ mental states. In this paper, I argue that the standard way of framing DSP leaves the debate at an impasse. I suggest two alternative interpretations of the idea that we see others’ mental states: others’ mental states are represented in the content of our perception, and we have basic perceptual beliefs about others’ mental states. I argue that the latter interpretation of DSP is more promising and examine (...) the kinds of mental states that plausibly could satisfy this version of DSP. (shrink)

I present a perceptual account of other minds that combines a Husserlian insight about perceptual experience with a functionalist account of mental properties.

Abstract: Some propose that the question of how you know that James is angry can be adequately answered with the claim that you see that James is angry. Call this the Perceptual Hypothesis. Here, I examine that hypothesis. I argue that there are two different ways in which the Perceptual Hypothesis could be made true. You might see that James is angry by seeing his bodily features. Alternatively, you might see that James is angry by seeing his anger. If you (...) see that James is angry in the first way, your knowledge is inferential. If you see that James is angry in the second way, your knowledge is not inferential. These are different ways of knowing that James is angry. So the Perceptual Hypothesis alone does not adequately answer the question of how you know that fact. To ascertain how you know it, we need to decide whether or not you saw his anger. This is an epistemological argument. But it has consequences for a theory of perception. It implies that there is a determinate fact about which features of an object you see. This fact is made true independently of what you come to know by seeing. In the final section of the paper, I seek to undermine various ways in which the claim that you see James' anger may be thought implausible. (shrink)

It is widely held that introspection-based self-ascriptions of mental states are immune to error through misidentification , relative to the first person pronoun. Many have taken such errors to be logically impossible, arguing that the immunity holds as an “absolute” necessity. Here I discuss an actual case of craniopagus twins—twins conjoined at the head and brain—as a means to arguing that such errors are logically possible and, for all we know, nomologically possible. An important feature of the example is that (...) it is one where a person may be said to be introspectively aware of a mental state that occurs outside of her own mind. Implications are discussed for views of the relation between introspection and mental state ownership, and between introspection and epistemic criteria for the “mark of the mental.”. (shrink)

I argue that the feeling that one is the owner of his or her mental states is not an intrinsic property of those states. Rather, it consists in a contingent relation between consciousness and its intentional objects. As such, there are (a variety of) circumstances, varying in their interpretive clarity, in which this relation can come undone. When this happens, the content of consciousness still is apprehended, but the feeling that the content “belongs to me” no longer is secured. I (...) discuss the implications of a mechanism enabling personal ownership for understanding a variety of clinical syndromes as well normal mental function. (shrink)

According to the cohabitation account, all the persons that result from a fission event cohabit the same body prior to fission. This article concerns a problem for this account. Suppose Manuel and Jimena are suffering from an equally painful migraine. Unlike Jimena, however, Manuel will undergo fission. Assuming you have a spare painkiller, whom should you give it to? Intuitively, you have no more reason to give it to one or the other. The problem is that the cohabitation account suggests (...) otherwise. According to the account, there are two persons cohabiting Manuel’s body, in which case you should arguably give them the pill, since doing so alleviates the pain of more beings. One response argues that the two persons cohabiting Manuel’s body share one pain. Thus, giving them the pill alleviates no more pain than giving it to Jimena, and therefore you have no more reason to do one or the other. The goal of this article is to show that this response fails. (shrink)

I argue that it is possible literally to perceive the emotions of others. This account depends upon the possibility of perceiving a whole by perceiving one or more of its parts, and upon the view that emotions are complexes. After developing this account, I expound and reply to Rowland Stout's challenge to it. Stout is nevertheless sympathetic with the perceivability-of-emotions view. I thus scrutinize Stout's suggestion for a better defence of that view than I have provided, and offer a refinement (...) of my own proposal that incorporates some of his insights. (shrink)

We ordinarily speak of being able to see that there are people on the bus, Students in the class, And children playing in the street. If human beings are understood to be conscious entities, Then one of our ways of knowing that there are other conscious entities in the world besides ourselves is by seeing that there are. We also speak of seeing that he is angry, She is depressed, And so on. It is argued that this is, Indeed, One (...) way of knowing that there are other minds (and, Hence, That the problem of other minds is not a special epistemological problem). What helps to obscure this fact is the confusion between visibility and knowability--The confusion between seeing his pain and seeing that he is in pain. (shrink)

Several authors have speculated that (1) the pharmaceutical, genetic or other technological enhancement of human mental capacities could result in the creation of beings with greater moral status than persons, and (2) the creation of such beings would harm ordinary, unenhanced humans, perhaps by reducing their immunity to permissible harm. These claims have been taken to ground moral objections to the unrestrained pursuit of human enhancement. In recent work, Allen Buchanan responds to these objections by questioning both (1) and (2). (...) I argue that Buchanan’s response fails. However, I then outline an alternative response. This response starts from the thought that, though moral status-increasing human enhancements might render ordinary, unenhanced humans less immune to permissible harm, they need not worsen the overall distribution of this immunity across beings. In the course of the argument I explore the relation between mental capacity and moral status and between moral status and immunity to permissible harm. (shrink)

Do we have introspective access to our own thoughts? Peter Carruthers challenges the consensus that we do: he argues that access to our own thoughts is always interpretive, grounded in perceptual awareness and sensory imagery.

Animalists accuse the advocates of psychological approaches of identity of having to suffer a Problem of Too Many Thinkers. Eric Olson, for instance, is an animalist who maintains that if the person is spatially coincident but numerically distinct from the animal, then provided that the person can use its brain to think, so too can the physically indistinguishable animal. However, not all defenders of psychological views of identity assume the spatial coincidence of the person and the animal. Jeff McMahan and (...) lately Derek Parfit claim we are roughly brain-size, composed of just those parts of the human animal that directly produce thought. They claim to avoid the Problem of Too Many Thinkers because it is the brain-sized person who truly thinks, while the animal thinks only in a derivative sense in virtue of having a thinking proper part. Waiting in the wings are some dualists who claim that all materialist accounts fail to avoid the Problem of Too Many Thinkers. One such dualist, Dean Zimmerman, insists that wherever there is an ordinary material thing like a brain, there is also a mass with distinct persistence conditions and thus the threat of two material thinkers. Zimmerman contends that only positing an immaterial thinker can avoid the problem. (shrink)
