Book Description
The idea of a disjunctive theory of visual experiences first found expression in J.M. Hinton's pioneering 1973 book Experiences. In the first monograph in this exciting area since then, William Fish develops a comprehensive disjunctive theory, incorporating detailed accounts of the three core kinds of visual experience--perception, hallucination, and illusion--and an explanation of how perception and hallucination could be indiscriminable from one another without having anything in common. In the veridical case, Fish contends that the perception of a particular state of affairs involves the subject's being acquainted with that state of affairs, and that it is the subject's standing in this acquaintance relation that makes the experience possess a phenomenal character. Fish argues that when we hallucinate, we are having an experience that, while lacking phenomenal character, is mistakenly supposed by the subject to possess it. Fish then shows how this approach to visual experience is compatible with empirical research into the workings of the brain and concludes by extending this treatment to cover the many different types of illusion that we can be subject to.

Book Description
In a major Contribution to the theory of perception, A.D.Smith presents a truly original defense of direct realism the view that in perception we are directly aware of things in a physical world. It offers two arguements against direct realism-one conceening illusion, and one concerning hallueination that upto now no theory of perception could adequately rebut.At the heart of Smiths theory is a new way of drawing the distinction between perception and sensation alone with an unusual treatment of the nature of object of halluecination .

Book Description
It is commonly held that the experiences involved in cases of perception, illusion and hallucination all have the same nature. Disjunctivists deny this. They maintain that the kind of experience you have when you perceive the world isn’t one you could be having if you were hallucinating. A number of important debates in the philosophy of mind and epistemology turn on the question of whether this disjunctivist view is tenable. This is the first book-length introduction to this contested issue. Matthew Soteriou explains the accounts of perception that disjunctivists seek to defend, such as naïve realism, and the accounts to which they are opposed, such as sense-datum theories and representationalist theories. He goes on to introduce and assess key questions that arise in these debates: Is disjunctivism consistent with what has been established by the science of perception? Does introspective reflection support naïve realism? Can disjunctivism be motivated by appeal to the role that perception plays in enabling us to think demonstratively about mind-independent objects and qualities in our environment? Does disjunctivism offer the best account of perceptual knowledge? What can disjunctivists say about the nature of hallucination and illusion? Including chapter summaries, annotated further reading and a glossary, this book is an ideal starting point for anyone studying disjunctivism for the first time, as well as for more advanced students and researchers.

Book Description
Perception is one of the most pervasive and puzzling problems in philosophy, generating a great deal of attention and controversy in philosophy of mind, psychology and metaphysics. If perceptual illusion and hallucination are possible, how can perception be what it intuitively seems to be, a direct and immediate access to reality? How can perception be both internally dependent and externally directed? Perception is an outstanding introduction to this fundamental topic, covering both the perennial and recent work on the problem. Adam Pautz examines four of the most important theories of perception: the sense datum view; the internal physical state view; the representational view; and naïve realism, assessing each in turn. He also discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition of chapter summaries, suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.

Book Description
Naturalistic cognitive science, when realistically rendered, rightly maintains that to think is to deploy contentful mental representations. Accordingly, conscious perception, memory, and anticipation are forms of cognition that, despite their introspectively manifest differences, may coincide in content. Sometimes we remember what we saw; other times we predict what we will see. Why, then, does what it is like consciously to perceive, differ so dramatically from what it is like merely to recall or anticipate the same? Why, if thought is just representation, does the phenomenal character of seeing a sunset differ so stunningly from the tepid character of recollecting or predicting the sun's descent? J. Christopher Maloney argues that, unlike other cognitive modes, perception is in fact immediate, direct acquaintance with the object of thought. Although all mental representations carry content, the vehicles of perceptual representation are uniquely composed of the very objects represented. To perceive the setting sun is to use the sun and its properties to cast a peculiar cognitive vehicle of demonstrative representation. This vehicle's embedded referential term is identical with, and demonstrates, the sun itself. And the vehicle's self-attributive demonstrative predicate is itself forged from a property of that same remote star. So, in this sense, the perceiving mind is an extended mind. Perception is unbrokered cognition of what is real, exactly as it really is. Maloney's theory of perception will be of great interest in the philosophy of mind and cognitive science.

Book Description
In order to accurately describe and diagnose psychiatric illness, practitioners require in-depth knowledge of the signs and symptoms of behavioral disorders. Descriptive Psychopathology provides a broad review of the psychopathology of psychiatric illness, beyond the limitations of the DSM and ICD criteria. Beginning with a discussion of the background to psychiatric classification, the authors explore the problems and limitations of current diagnostic systems. The following chapters then present the principles of psychiatric examination and diagnosis, described with accompanying patient vignettes and summary tables, and related to different diagnostic concerns. A thought-provoking conclusion proposes a restructuring of psychiatric classification based on the psychopathology literature and its validating data. Written for psychiatry and neurology residents, as well as clinical psychologists, it is invaluable to anyone who accepts the responsibility for the care of patients with behavioral syndromes.

Book Description
The philosophy of perception investigates the nature of our sensory experiences and their relation to reality. Raising questions about the conscious character of perceptual experiences, how they enable us to acquire knowledge of the world in which we live, and what exactly it is we are aware of when we hallucinate or dream, the philosophy of perception is a growing area of interest in metaphysics, epistemology, and philosophy of mind. William Fish’s Philosophy of Perception introduces the subject thematically, setting out the major theories of perception together with their motivations and attendant problems. While providing historical background to debates in the field, this comprehensive overview focuses on recent presentations and defenses of the different theories, and looks beyond visual perception to take into account the role of other senses. Topics covered include: the phenomenal principle perception and hallucination perception and content sense-data, adverbialism and idealism disjunctivism and relationalism intentionalism and combined theories the nature of content veridicality perception and empirical science non-visual perception. With summaries and suggested further reading at the end of each chapter, this is an ideal introduction to the philosophy of perception.
