Donald Norman, author of Living with Complexity and The Design of Everyday Things <br> Doug Hofstadter and Emmanuel Sander rip apart everyday understanding to reveal insights of both mind and universe. The key is to recognize that analogies and concepts are the same things, that they are ubiquitous, universal, and key to understanding human thought. Easy to read, but deep to comprehend. The result is both enjoyable and profound. <br><br>Barbara Tversky, Professor Emerita of Psychology, Stanford University, and Professor of Psychology and Education, Columbia Teachers College<br> Surfaces and Essences has much of both. And more. This book is fun! And serious. Category, analogy (and similarity) are at the core of cognition. On every page, you will find delights: you will be informed, you will be puzzled; you will agree vehemently and you will disagree just as vehemently; you will ponder. And you will return for more. <br>
