John Foster presents a penetrating investigation into the question: what is it to perceive a physical object? Is perceptual contact with a physical object, he asks, something fundamental, or does it break down into further factors? If the latter, what are these factors, and how do they combine to secure the contact? For most of the book, Foster addressed these questions in the framework of a realist view of the physical world. But the arguments which thereby unfold - arguments which (...) undermine direct realism and establish a version of the sense-datum theory - lead to the conclusion that we do no perceive physical objects at all. The only way to avoid this conclusion is by abandoning physical realism for a form of idealism, and this is the option which Foster finally embraces. The Nature of Perception makes an important contrbution to the ongoing debate: it sheds fresh light on the traditional issues, and breathes new life into positions which most current philosophers assumeto be dead.

The Problem of Perception offers two arguments against direct realism--one concerning illusion, and one concerning hallucination--that no current theory of ...

This paper, which has both a historical and a polemical aspect, investigates the view, dominant throughout the eighteenth and nineteenth centuries, that the sense of sight is, originally, not phenomenally three-dimensional in character, and that we must come to interpret its properly two-dimensional data by reference to the sense of 'touch'. The principal argument for this claim, due to Berkeley, is examined and found wanting. The supposedly confirming findings concerning 'Molyneux subjects' are also investigated and are shown to be either (...) irrelevant or disconfirming. Recent investigations on infant and neonatal perception are discussed and are also found to be disconfirming. An innatist version of the theory is then considered and is shown to be undermined by the largely 'Gibsonian' character of early space-perception. Finally three recent arguments in favour of the theory - two from psychologists, one from a philosopher - are considered and answered. (shrink)

In The Problem of Perception, A.D. Smith’s central aim is to defend the view that we can directly perceive ordinary objects, such as cups, keys and the like.1 The book is organized around the two arguments that Smith considers to be serious threats to the possibility of direct perception: the argument from illusion, and the argument from hallucination. The argument from illusion threatens this possibility because it concludes that indirect realism is true. Indirect realism is the view that we perceive (...) mind-independent ordinary objects, but can only do so indirectly, by perceiving mind-dependent objects: objects whose existence depends on being perceived or thought about. The argument from hallucination draws a similar conclusion: if we perceive mindindependent ordinary objects at all, then our perception of them is indirect in the same way. In responding to these arguments, Smith develops an account of percep- tual consciousness. Perceptual consciousness is a kind of experience, distinct from what Smith calls ‘mere sensory experiences’, or equivalently, ‘mere sensation’. Perceptual consciousness is experience that is properly percep- tual, in which one has the phenomenology of perceiving things in the external world (including one’s body) that exist independently of one’s mind. Perceptual consciousness on its own does not suffice for actually being in perceptual contact with mind-independent reality, although it suffices for it to seem as if one i s . It follows that perceptual consciousness does not suffice for direct perception of ordinary objects, or for direct realism. Nevertheless, Smith holds that the correct account of perceptual consciousness is a crucial element in blocking the arguments from illusion and hallucination, and therefore in supporting the possibility of direct perception. This is an extraordinarily engaging book. Within a single, unified narrative, one encounters the views of many philosophers—Husserl, Fine, Broad, Sextus Empiricus, Loar, Schopenhauer, Meinong, Burge, Dilthey, Russell, Dennett, Sartre, O’Shaughnessy, Evans, Berkeley, Craig, Brentano and many....

In her careful consideration of my book, The Problem of Perception (henceforth, PP), Susanna Siegel highlights what she takes to be a number of shortcomings in the work. First, she suggests that a sense‐datum theorist has two options–what she calls the “complex sense‐data option” and the “two‐factor option”–that survive the argument of my book unscathed. I consider these two options in the first two sections of this reply. Secondly, she criticizes my suggestion that there are three and only three basic (...) and independent sources of perceptual consciousness: an issue I take up in my third section. Thirdly, she expresses reservations about my response to the argument from hallucination. In particular, she argues that the phenomenological considerations on which I put so much weight cannot settle the fundamental issue here. I address this criticism in the fourth section of this reply. Finally, she spends a certain amount of time discussing the notion of a “veridicality‐rele‐vant property”, a topic to which I devote the concluding section of this reply. (shrink)

The senses, or sensory modalities, constitute the different ways we have of perceiving the world, such as seeing, hearing, touching, tasting and smelling. But how many senses are there? How many could there be? What makes the senses different? What interaction takes place between the senses? This book is a guide to thinking about these questions. Together with an extensive introduction to the topic, the book contains the key classic papers on this subject together with nine newly commissioned essays. One (...) reason that these questions are important is that we are receiving a huge influx of new information from the sciences that challenges some traditional philosophical views about the senses. This information needs to be incorporated into our view of the senses and perception. Can we do this whilst retaining our pre-existing concepts of the senses and of perception or do we need to revise our concepts? If they need to be revised, then in what way should that be done? Research in diverse areas, such as the nature of human perception, varieties of non-human animal perception, the interaction between different sensory modalities, perceptual disorders, and possible treatments for them, calls into question the platitude that there are five senses, as well as the pre-supposition that we know what we are counting when we count them as five (or more). This book will serve as an inspiring introduction to the topic and as a basis from which further new research will grow. (shrink)
