Over the past 20 years, Purves has developed a theory of perception that he calls 'a wholly empirical strategy.' In this book, he provides a lucid explanation and comprehensive defense of his provocative ideas, and sets it in a broader evolutionary context. In addition to being of broad and general interest, it challenges biologists to find out how the brain accomplishes the remarkable feats that Purves documents.
