In "What is it Like to be a Bat?" Thomas Nagel argues that we cannot imagine what it is like to be a bat or presently understand how physicalism might be true. Both arguments have been seriously misunderstood. I defend them against various objections, point out a problem with the argument against physicalism, and show how the problem can be solved.

My purpose in this paper is to discuss and defend an objection to physicalist or materialist accounts of the mind.

This paper suggests that it is largely a want of notional distinctions which fosters the "explanatory gap" that has beset the study of consciousness since T. Nagel's revival of the topic. Modifying Ned Block's controversial claim that we should countenance a "phenomenal module" which exists in its own right, we argue that there is a way to recuperate the intuitions he appeals to without engaging in an onerous reification of the facet in question. By renewing with the full type/token/tone trichotomy (...) developed by C. S. Peirce, we think the distinctness Block (rightly) calls attention to can be seen as stemming not from any separate module lurking within the mind, but rather from our ability to prescind qualities from occurrences.

In this article I distinguish the notion of there being something it is like to be a certain kind of creature from that of there being something it is like to have a certain kind of experience. Work on consciousness has typically dealt with the latter while employing the language of the former. I propose several ways of analyzing what it is like to be a certain kind of creature and find problems with them all. The upshot is that even (...) if there is something it is like to have certain kinds of experience, it does not follow that there is anything it is like to be a certain kind of creature. Skepticism about the existence of something that it is like to be an F is recommended. (shrink)

The concept of consciousness has been the source of much philosophical, cognitive scientific and neuroscientific discussion for the past two decades. Many scientists, as well as philosophers, argue that at the moment we are almost completely in the dark about the nature of consciousness. Stuart Sutherland, in a much quoted remark, wrote that.

I discuss the meaning of 'There's something e is like', in the context of a reply to Eric Lormand's 'The explanatory stopgap'. I argue that Lormand is wrong to think it has a specially perceptual meaning. Rather, it has one of at least four candidate meanings: (a) e is some way as regards its subject; (b) e is some way and e's being that way is in the possession of its subject; (c) e is some way in the awareness of (...) its subject; (d) e's subject is the "experiencer" of e. I provide additional argumentation for the view in this paper that in the context, 'like this' functions as a predicate variable. (shrink)

It is common parlance among philosophers who inquire into the nature of consciousness to speak of there being something it is like for the subject of a mental state to be in it. The popularity of the ‘what-it-is-like’ phrase stems, in part, from the assumption that it enables us to distinguish, in an intuitive and illuminating way, between conscious and unconscious mental states: conscious mental states, unlike unconscious mental states, are such that there is something it is like for their (...) subjects to be in them. The ‘what-it-is-like’ phrase, however, has not gone unopposed; some very clever philosophers have vigorously disputed it. Peter Hacker, for example, argues that the phrase should be abandoned because it is ungrammatical, and Paul Snowdon argues that it should be abandoned because the propositions expressed by its usage are either trivial or false. This paper mounts a case for the claim that neither of these conclusions is warranted. Against Hacker, it is argued that the arguments he produces for the ungrammaticality of the phrase are unpersuasive, and against Snowdon it is argued that he fails to consider a plausible and independently motivated interpretation of the phrase, and that on this interpretation, the propositions expressed by its usage are nontrivially true.

The central claim of this paper is that what it is like to see green or any other perceptible property is just the perceptual mode of presentation of that property. Perceptual modes of presentation are important because they help resolve a tension in current work on consciousness. Philosophers are pulled by three mutually inconsistent theses: representational externalism, representationalism, and phenomenal internalism. I throw my hat in with defenders of the first two: the externalist representationalists. We are faced with the problem (...) of explaining away intuitions that favor phenomenal internalism. Perceptual modes of presentation account for what it is like to see properties in a way that accommodates those intuitions without vindicating phenomenal internalism itself. Perceptual MoPs therefore provide a new way of being an externalist representationalist. (shrink)

Is there an explanatory gap between raw feels and raw material? Some philosophers argue, and many other people believe, that scientific explanations of conscious experience cannot be as satisfying as typical scientific explanations elsewhere, even in our wildest dreams. The underlying philosophical claims are.

Physicalism in philosophy of mind is the doctrine that mental states and processes, if they are something, are physical states and processes. Notoriously, Frank Jackson has attacked physicalism with the knowledge argument. This paper does not consider whether the knowledge argument is successful. Instead, the author argues that the ability reply to the knowledge argument fails. The central assumption of this objection is that Mary, by having colour experiences, acquires a set of abilities rather than new beliefs as required by (...) the knowledge argument. Against the ability reply, it is maintained that Mary on her release acquires new beliefs about objects looking the same colour. As a preliminary, it is shown, against an important criticism of the knowledge argument, that we can make sense of what Mary knows about colour experience when in the black-and-white laboratory.

ABSTRACT. Thought experiments about de se attitudes and Jackson’s original Knowledge Argument are compared with each other and discussed from the perspective of a computational theory of mind. It is argued that internal knowledge, i.e. knowledge formed on the basis of signals that encode aspects of their own processing rather than being intentionally directed towards external objects, suffices for explaining the seminal puzzles without resorting to acquaintance or phenomenal character as primitive notions. Since computationalism is ontologically neutral, the account also (...) explains why neither Lewis’s two gods nor Mary’s surprise in the Knowledge Argument violate physicalism. (shrink)

Phenomenology is based on a doctrine of evidence that accords a crucial role to the human capacity to conceptualise or ‘intuit’ features of their experience. However, there are grounds for holding that some experiential entities to which phenomenologists are committed must be intuition-transcendent or ‘dark’. Examples of dark phenomenology include the very fine-grained perceptual discriminations which Thomas Metzinger calls ‘Raffman Qualia’ and, crucially, the structure of temporal awareness. It can be argued, on this basis, that phenomenology is in much the (...) same epistemological relationship to its own subject matter as descriptive (i.e. ‘phenomenological’) physics or biology are to physical and biological reality: phenomenology cannot tell us what phenomenology is really ‘about’. This does not mean we should abjure phenomenology. It implies, rather, that the domain of phenomenology is not the province of a self-standing, autonomous discipline but must be investigated with any empirically fruitful techniques that are open to us (e.g. computational neuroscience, artificial intelligence, etc.). Finally, it entails that while a naturalized phenomenology should be retained as a descriptive, empirical method, it should not be accorded transcendental authority. (shrink)

It is common for philosophers to hold that experience can be characterized in a basic way as being something it is like for someone to undergo. In the paper it is argued that when this slogan is examined it is in some respects trivial and in others mistaken. It is concluded that the slogan should be abandoned.

Colours and consciousness both present us with metaphysical problems. But what exactly are the problems? According to standard accounts, they are roughly the following. On the one hand, we have reason to believe, about both colour and consciousness, that they are identical with some familiar natural phenomena. But on the other hand, it is hard to see how these identities could obtain. I argue that this is an adequate characterisation of our metaphysical problem of colour, but a mischaracterisation of the (...) problem of consciousness. It mischaracterises the problem by presenting consciousness as more 'colour-like' than we have reason to take it to be. The real problem of consciousness is, I suggest, that almost nothing theoretically useful is known about this phenomenon at present. I also explore some implications of this perspective on the problem of consciousness. Given the shape of the problem, I argue that we can't rule out all forms of eliminativism about consciousness. Nor can we rule out that future research will close the ' explanatory gap' that consciousness gives rise to. (shrink)
