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? Perception is an outstanding introduction to this fundamental topic, covering both the perennial problems and recent work on the problem. Adam Pautz examines four of the most important theories of perception: the sense datum view; the Qualia view; the intentional view; and the disjunctive view, assessing each in turn. He also discusses the relationship between perception and the physical world, in particular arguments for physical reductivism in perception, and the problem of sensory qualities such as color. Useful examples are included throughout the book to illustrate the problematic nature of perception, including consciousness, hallucination, illusion, blindsight, the reliability of introspection, and whether perception is conceptual or non-conceptual. The addition of chapter summaries, annotated further reading and a glossary make Perception essential reading for anyone studying the topic and students of philosophy of mind, philosophy of psychology and metaphysics.
