"Dretske's chapter 'Sensation and Perception' in his new book Knowledge and the Flow of Information
is superb.... This is the first time in my experience that I have clarified my understanding of the psychology of perception and cognition by reading what a philosopher has to say on these subjects.... For an outsider, Dretske has an amazingly solid grasp of and sophistication about the field of perception. His argument is that sensory experience (perception) should be thought of as information in analog form and the mental activity of classifying, identifying, or, in short, cognizing what we perceive should be thought of as information extracted from perception and thus converted to digital form. I will recommend the book to my students and colleagues."
"Knowledge and the Flow of Information
is distinctive and original... such topics as knowledge, perception, sensation, 'content,' and concepts are treated in a unified framework, which should interest philosophers and cognitive psychologists alike. This book, like his earlier work, has many suggestive themes and insights, lucidly presented, but in a more interdisciplinary setting."
—Alvin I. Goldman
"Few who read this book will fail to profit. It is an intelligent, imaginative, well-informed, well-written investigation, of important issues in epistemology and philosophy of mind. The book itself is well-produced and sensibly priced. If Consumer Reports
rated philosophy books, this one would be a BEST BUY."
—Canadian Philosophical Review
"The author of this book is a philosopher, and he has written primarily to and for other philosophers. This work, however, is of interest to contemporary cognitive psychologists because Dretske has attempted to extend the concept of information into types of information similar to what we would commonly call knowledge. Indeed, cognitive scientists who are more broadly concerned with the nature of knowledge and language comprehension will be interested in Knowledge and the Flow of Information

This volume presents an attempt to develop a theory of knowledge using ideas derived from the mathematical theory of communication developed by Claude Shannon. Information is seen as an objective commodity defined by the dependency relations between distinct events. Knowledge is then analyzed as information caused belief.
