William Bechtel is professor of philosophy and science studies at the University of California, San Diego. He is the author and editor of many books, including Discovering Complexity (with Robert C. Richardson, 1993) and Connectionism and the Mind (with Adele Abrahamsen, 2002), and he is editor of the journal Philosophical Psychology. He is the current chair of the Cognitive Science Society and past president of the Society for Philosophy and Psychology and the Southern Society for Philosophy and Psychology.

“This volume…will be useful not only to cell biologists interested in the embryology of their field, but also to theorists and historians of science concerned with the boundaries of fields of intellectual inquiry.” -Choice
