John Heil’s new book ranges over many of the major topics in metaphysics, including substance, properties, causation, space, time, parts and wholes, modality, essence, agency, and consciousness. It has interesting things to say about all of the issues it discusses, but there are three topics that are especially prominent in the book, and which help to organize the discussion. These all flow from the differences between our everyday, commonsense understanding of reality and the representations that are offered by science.

I argue for three claims. (1) The phenomenology of visual experience is exhausted by awareness of appearance properties (i.e., certain constantly changing characteristics of external objects that are relational and viewpoint‐dependent). (2) Cognition differs from perception in that it has a purely discursive or linguistic dimension, whereas perception is pervasively analog and iconic; but this does not determine a border between the two domains, for cognition also has a massive iconic dimension. And (3) certain raging debates in teleosemantics can be resolved by acknowledging that perceptual representations in more primitive organisms tend to have dual contents (e.g., both small, moving black object, and food).

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.

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.

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.

This chapter focuses on three parts of Goldman's work, beginning with his model of the processes that underlie ascriptions of mental states to others. It maintains that Goldman errs in ignoring the role that knowledge of testimony plays in those processes. The second topic will be the theory of introspection that Goldman developed in the early 1990s. The reader may be surprised to find that most of the author remarks are concerned with this topic, given that Goldman's views about introspection have changed dramatically in recent years. It is the author impression, however, that that his earlier theory has been hugely influential, and that it continues to shape research on cognitive phenomenology and self‐knowledge. The third topic will be Goldman's more recent theory of introspection ‐ the theory that he develops in Simulating Minds. The chapter sketches alternatives to the main components of Goldman's theory, together with some of the motivation for accepting them.

Jaegwon Kim relied principally on armchair methods in approaching problems in philosophy of mind. This paper is concerned with the nature of such methods and their prospects of success. Identifying the main armchair methods as introspection, modal reasoning involving conceivability tests, and conceptual analysis, the paper argues that insofar as the first two members of this trio aim to reveal the constitutive metaphysical natures of mental states, they are unable to reach their objective. In contrast, it defends conceptual analysis, arguing that Quine’s attempt to discredit it fails. More specifically, it maintains that a certain form of conceptual role semantics is immune to Quine’s strictures against meaning, and that this conception of meaning allows room for armchair discoveries about the meanings of our words (though it has no tendency to provide access to deep facts about the constitutive metaphysical natures of extralinguistic entities).

Rowlands is concerned to explain and defend a doctrine about the relationship between mental states and physical states that he calls supervenience materialism. Very roughly speaking, this is the doctrine that it is the possession of physical properties by an object that makes for or determines the possession of mental properties by that object. In explaining this doctrine, Rowlands discusses various questions of interpretation, such as what should be meant by ‘determines’ and by ‘physical property’, and he also considers the implications of the doctrine for a family of questions about psychological laws and psychological explanations. In defending the doctrine, he does not attempt anything like a direct proof of its truth, but rather argues that it is to be preferred to other materialist doctrines that are studied in the literature.

I will be concerned in these pages with the views that Gilbert Harman puts forward in his immensely stimulating paper Self-Reflexive Thoughts.¹ Harman maintains that self referential thoughts are possible, and also that they are useful. I applaud both of these claims. An example of a self referential thought is the thought that every thought, including this present one, has a logical structure. I feel sure that this thought exists, for I have entertained it on a number of occasions. Moreover, I feel that it is extremely useful. Without deploying it, how could we tell the whole truth about the nature of thoughts?

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.
