"Gottlieb's outrageously good"
This book provided one of the most interesting insights I've ever had in to how people originally began to inspect their lives and the world around them. It traces, literally, how people started to think. I'd never understood where logic came from. As someone else enthused, "ignore this book at your peril" or something like that. There is nothing I've heard out there, contemporary or otherwise, which comes a gnat's hair close to paralleling the degree of intellectual clarity this book describes.
