New. No dust jacket. 436 p. This is the most rigorous, comprehensive treatment of race differences ever published. Philosopher Michael Levin's classic work first appeared in 1997 but quickly went out of print. Used copies sold for as much as $500.00. New Century Foundation has now published a completely reset, corrected edition, with a foreword by Jared Taylor. Anyone with an interest in race and the courage to follow the scientific data wherever they lead will find a goldmine of information, analysis, and wisdom in this classic treatment of one of the most profoundly important and taboo subjects of our time.
