"Humanity" is ultimately little more than acompendium of conventional wisdom. Glover offers little clear explanationof why these atrocities happened, content with describing them as theoutcome of a disastrous meeting between the darker aspects of "psychology"and new destructive technologies. Even his moral lessons are confusing yetpredictable; he observes that having a strong sense of identity can helppeople resist committing terrible acts, yet that at times a strongidentity can actually be forged in the commission of horrors. Religionplays a minor role in his analysis; problems of character are consideredin terms of identity rather than faith. More attention to the history ofthese terrible regimes--rather than simply repeating how terrible theywere--would have deepened not only the historical but the moral weight ofGlover's book.
