The great virtue of Block's discussion is its blending of philosophy and science, instigating an exciting empirical agenda to test his claims. Does cognition never adapt? Do all perceptual properties adapt? Do Block's signatures generalize to nonhuman animals, artificial systems, or other senses? Can iconicity account for the full breadth of visual representation? Whatever the answers, Block's approach offers deep insight into two fundamentally different aspects of mind.

This is a major work in the philosophy of perception. Its central insight is that many debates in philosophy of perception not only assume a distinction between perception and cognition, but often assume a specific way to draw it. That's why giving a theory of the distinction is such a fertile project, and why the book treats so many of the issues that shape contemporary work in this area - including the nature of consciousness, modularity, cognitive penetrability, and the differences between perception and memory, conceptual and non-conceptual contents, and propositional and non-propositional structures for content. The book invites responses along two dimensions: by engaging Block's theory of what grounds the distinction between perception and cognition, or by engaging what he says about the topics he treats in defending this theory. For this reason, the book has made a big impact.

Powerfully-argued, steeped in relevant science, and overflowing with insight, Block's landmark book will shape and stimulate debates about perception and thought for years to come.
