Adler’s other books include “Ten Philosophical Mistakes” and “Six Great Ideas,” and he has served as chairman of the board of editors of Encyclopedia Britannica (http://www.eb.com/), director of the Institute of Philosophical Research, and senior associate of the Aspen Institute for Humanistic Studies (http://www.aspeninst.org/). In “A Guidebook to Learning,” Adler traces the history of the organization of knowledge from Greek and Roman antiquity to modern times. Ever wonder why a Ph.D. is a doctorate of philosophy? This book is for you.
