The classic, influential essay in 'descriptive metaphysics' by the distinguished English philosopher.

A collection of some of Sellars' lectures and articles from 1951 to 1962.

Consciousness and Mind presents David Rosenthal's influential work on the nature of consciousness. Central to that work is Rosenthal's higher-order-thought theory of consciousness, according to which a sensation, thought, or other mental state is conscious if one has a higher-order thought that one is in that state. The first four essays develop various aspects of that theory. The next three essays present Rosenthal's homomorphism theory of mental qualities and qualitative consciousness, and show how that theory fits with and helps sustain (...) the HOT theory. A crucial feature of homomorphism theory is that it individuates and taxonomizes mental qualities independently of the way we're conscious of them, and indeed independently of our being conscious of them at all. So the theory accommodates the qualitative character not only of conscious sensations and perceptions, but also of those which fall outside our stream of consciousness. Rosenthal argues that, because this account of mental qualities makes no appeal to consciousness, it enables us to dispel such traditional quandaries as the alleged conceivability of undetectable quality inversion, and to disarm various apparent obstacles to explaining qualitative consciousness and understanding its nature. Six further essays build on the HOT theory to explain various important features of consciousness, among them the complex connections that hold in humans between consciousness and speech, the self-interpretative aspect of consciousness, and the compelling sense we have that consciousness is unified. Two of the essays, one an extended treatment of homomorphism theory, appear here for the first time. There is also a substantive introduction, which draws out the connections between the essays and highlights their implications. (shrink)

Dorit Bar-On develops and defends a novel view of avowals and self-knowledge. Drawing on resources from the philosophy of language, the theory of action, epistemology, and the philosophy of mind, she offers original and systematic answers to many long-standing questions concerning our ability to know our own minds. We are all very good at telling what states of mind we are in at a given moment. When it comes to our own present states of mind, what we say goes; an (...) avowal such as "I'm feeling so anxious" or "I'm thinking about my next trip to Paris," it is typically supposed, tells it like it is. But why is that? Why should what I say about my present mental states carry so much more weight than what others say about them? Why should avowals be more immune to criticism and correction than other claims we make? And if avowals are not based on any evidence or observation, how could they possibly express our knowledge of our own present mental states? Bar-On proposes a Neo-Expressivist view according to which an avowal is an act through which a person directly expresses, rather than merely reports, the very mental condition that the avowal ascribes. She argues that this expressivist idea, coupled with an adequate characterization of expression and a proper separation of the semantics of avowals from their pragmatics and epistemology, explains the special status we assign to avowals. As against many expressivists and their critics, she maintains that such an expressivist explanation is consistent with a non-deflationary view of self-knowledge and a robust realism about mental states. The view that emerges preserves many insights of the most prominent contributors to the subject, while offering a new perspective on our special relationship to our own minds. (shrink)

A touchstone of much modern theorizing about the mind is the idea, still tac- itly accepted by many, that a state's being mental implies that it's conscious. This view is epitomized in the dictum, put forth by theorists as otherwise di-.

Sellars's short autobiography. It covers the period of his life up to his first publications, showing the breadth of his background and influences in philosophy.

As G. E. Moore famously observed, sentences such as 'It's raining but I don't think it is', though they aren't contradictory, cannot be used to make coherent assertions.' The trouble with such sentences is not a matter of their truth conditions; such sentences can readily be true. Indeed, it happens often enough with each of us that we think, for example, that it isn't raining even though it is. This shows that such sentences are not literally contradictory. But even though (...) such sentences have unproblematic truth conditions, we cannot say the same about their conditions of assertibility. There are no circumstances in which one can use such sentences to perform coherent assertoric speech acts. Situations exist in which these sentences would be true, but none in which anybody could use them to say so. (shrink)

Moore’s paradox occurs with sentences, such as (1) It’s raining and I don’t think it’s raining. which are self-defeating in a way that prevents one from making an asser- tion with them.1 But Mark Crimmins has given us a case of a sentence that is syntactically just like (1) but is nonetheless assertible. Suppose I know somebody, and know or have excellent reason to believe that I know that very person under some other guise. I do not know what that (...) other guise is, though I do know that I believe that the person I know under that other guise is an idiot. (shrink)
