This is a book about sensory states and their apparent characteristics. It confronts a whole series of metaphysical and epistemological questions and presents an argument for type materialism: the view that sensory states are identical with the neural states with which they are correlated. According to type materialism, sensations are only possessed by human beings and members of related biological species; silicon-based androids cannot have sensations. The author rebuts several other rival theories, and explores a number of important issues: the (...) forms and limits of introspective awareness of sensations, the semantic properties of sensory concepts, knowledge of other minds, and unity of consciousness. The book is a significant contribution to the philosophy of mind, and has much to say to psychologists and cognitive scientists. (shrink)

This book presents a comprehensive theory of consciousness. The initial chapter distinguishes six main forms of consciousness and sketches an account of each one. Later chapters focus on phenomenal consciousness, consciousness of, and introspective consciousness. In discussing phenomenal consciousness, Hill develops the representational theory of mind in new directions, arguing that all awareness involves representations, even awareness of qualitative states like pain. He then uses this view to undercut dualistic accounts of qualitative states. Other topics include visual awareness, visual appearances, (...) emotional qualia, and meta-cognitive processing. This important work will interest a wide readership of students and scholars in philosophy of mind and cognitive science. (shrink)

In the first chapter of his Knowledge and Lotteries, John Hawthorne argues that thinkers do not ordinarily know lottery propositions. His arguments depend on claims about the intimate connections between knowledge and assertion, epistemic possibility, practical reasoning, and theoretical reasoning. In this paper, we cast doubt on the proposed connections. We also put forward an alternative picture of belief and reasoning. In particular, we argue that assertion is governed by a Gricean constraint that makes no reference to knowledge, and that (...) practical reasoning has more to do with rational degrees of belief than with states of knowledge.

What is the role of conscious experience in the epistemology of perceptual knowledge: how should we characterise what is going on in seeing that o is F in order to illuminate the contribution of seeing o to their status as cases of knowing that o is F? My proposal is that seeing o involves conscious acquaintance with o itself, the concrete worldly source of the truth that o is F, in a way that may make it evident to the subject (...) that o is an instance of ‘x is F’ as she understands this, and hence evident that o is F. Seeing that o is F is thus a way of its being evident that o is F and is therefore a way of knowing that o is F. (shrink)

This volume presents a selection of essays by the leading philosopher Christopher S. Hill. Together, they address central philosophical issues related to four key concerns: the nature of truth; the relation between experiences and brain states; the relation between experiences and representational states; and problems concerning knowledge.

There is an important family of semantic notions that we apply to thoughts and to the conceptual constituents of thoughts - as when we say that the thought that the Universe is expanding is true. Thought and World presents a theory of the content of such notions. The theory is largely deflationary in spirit, in the sense that it represents a broad range of semantic notions - including the concept of truth - as being entirely free from substantive metaphysical and (...) empirical presuppositions. At the same time, however, it takes seriously and seeks to explain the intuition that there is a metaphysically or empirically 'deep' relation linking thoughts to reality. Thus, the theory represents a kind of compromise between deflationism and versions of the correspondence theory of truth. This book will appeal to students and professionals interested in the philosophy of logic and language. (shrink)

The type identity theory, according to which types of mental state are identical to types of physical state, fell out of favour for some years but is now being considered with renewed interest. Many philosophers are critically re-examining the arguments which were marshalled against it, finding in the type identity theory both resources to strengthen a comprehensive, physicalistic metaphysics and a useful tool in understanding the relationship between developments in psychology and new results in neuroscience. This volume brings together leading (...) philosophers of mind, whose essays challenge in new ways the standard objections to type identity theory, such as the multiple realizability objection and the modal argument. Other essays show how cognitive science and neuroscience are lending new support to type identity theory and still others provide, extend and improve traditional arguments concerning the theory's explanatory power.

Most areas of philosopher Edmund Husserl’s thought have been explored, but his views on logic, mathematics, and semantics have been largely ignored. These essays offer an alternative to discussions of the philosophy of contemporary mathematics. The book covers areas of disagreement between Husserl and Gottlob Frege, the father of analytical philosophy, and explores new perspectives seen in their work.

As the subtitle indicates, this book is concerned with the relationship between consciousness and the physical world. It recommends a novel and disturbingly pessimistic view about this topic that it calls “naturalistic mysterianism.” The view is naturalistic because it maintains that states of consciousness are reducible to physical properties of the brain. It counts as “mysterian” because it asserts that the physical properties in question are entirely beyond our ken—that they lie well beyond the scope of contemporary neuroscience, and quite (...) likely beyond the scope of any body of scientific knowledge that we might develop in the future. Naturalistic mysterianism thus affirms the unity of consciousness with the physical world, while also claiming that the nature of that unity will forever elude us, due to inherent limits of our cognitive capacities.

It is free to read at Oxford Scholarship Online and offered as a free PDF download from OUP and selected open access locations. Christopher S. Hill argues that perceptual experience constitutively involves representations of worldly items, and that the relevant form of representation can be explained in broadly biological terms. He then maintains that the representational contents of perceptual experiences are perceptual appearances, interpreted (...) as relational, viewpoint-dependent properties of external objects. There is also a complementary explanation of how the objects that possess these properties are represented. Hill maintains that perceptual phenomenology can be explained reductively in terms of the representational contents of experiences, and uses this doctrine to undercut the traditional arguments for dualism. This treatment of perceptual phenomenology is expanded to encompass cognitive phenomenology, the phenomenology of moods and emotions, and the phenomenology of pain. Hill also offers accounts of the various forms of consciousness that perceptual experiences can possess. One aim is to argue that phenomenology is metaphysically independent of these forms of consciousness, and another is to de-mystify the form known as phenomenal consciousness. The book concludes by discussing the relations of various kinds that perceptual experiences bear to higher-level cognitive states, including relations of format, content, and justification or support.

Visual experience is shaped by a number of factors that are independent of the external objects that we perceive—factors like lighting, angle of view, and the sensitivities of photoreceptors in the retina. This paper seeks to catalog, analyze, and explain the fluctuations in visual phenomenology that are due to such factors.

There are two main accounts of what it is for external objects to be presented in visual experience. According to particularism, particular objects are built into the representational contents of experiences. Existentialism is a quite different view. According to existentialism, the representational contents of perceptual experiences are general rather than particular, in the sense that the contents can be fully captured by existentially quantified statements. The present paper is a defense of existentialism. It argues that existentialism is much better equipped (...) than particularism to explain the contents of hallucinations, and it defends existentialism against three objections. (shrink)

In this critical notice of Kment's _Modality and Explanatory Reasoning_, we focus on Kment’s arguments for impossible worlds and on a key part of his discussion of the interactions between modality and explanation – the analogy that he draws between scientific and metaphysical explanation.

Schellenberg's book The unity of perception is full of innovative ideas and challenges to preconceptions. This discussion endorses several of Schellenberg's main contentions, but it also challenges her handling of several key topics, such as hallucinations and perceptual awareness of particulars, and it expresses doubts about the informativeness of her main analytic tool, the notion of a perceptual capacity.

In this paper I celebrate the virtues of Hurlburt and Schwitzgebel's path-breaking book on introspection, but I also exp-ress dissatisfaction with a few of its recurring themes. The main body of the paper consists of seven theses about the way in which the study of introspection should be conducted. Thus, to a large extent, the paper is a methodological proposal, though it also makes a number of concrete claims about the nature of introspection, and about the epistemological status of its (...) deliverances. The methodology I endorse is quite different than the one that Hurlburt advocates, but even so, it is compatible with assigning a large role to Descriptive Experience Sampling. Equally, while I am no fan of Schwitzgebel's radical scepti-cism about introspection, he and I are of like mind on a number of spe-cific epistemological issues, and we share the sense that it would be useful to draw on other areas of cognitive science in extending Descriptive Experience Sampling and refining it.

My goal is to formulate a theory of introspection that can be integrated with a strongly reductionist account of sensations that I have defended elsewhere. In pursuit of this goal, I offer a skeletal explanation of the metaphysical nature of introspection and I attempt to resolve several of the main questions about the epistemological status of introspective beliefs.

In order to defend her claim that the concept object is biologically determined, Carey must answer Quine's gavagai argument, which purports to show that mastery of any concept with determinate reference presupposes a substantial repertoire of logical concepts. I maintain that the gavagai argument withstands the experimental data that Carey provides, but that it yields to an a priori argument.

We introduce the notion of positive local combinatorial dividing-lines in model theory. We show these are equivalently characterized by indecomposable algebraically trivial Fraïssé classes and by complete prime filter classes. We exhibit the relationship between this and collapse-of-indiscernibles dividing-lines. We examine several test cases, including those arising from various classes of hypergraphs.

Chalmers’s anti-materialist argument runs as follows.
