This book is about the social causes of WW I. Adams points the finger at how manhood was defined, at the gulf between the sexes and how men desired the company of other men, at the boredom created by the Industrial Age, at how killing and blood-letting were prized, and at a crazed nationalism as the defining causes. Unfortunately, the book lacks power and by the end is nothing more than a diatribe against war.
