War! What Is It Good For? Conflict and the Progress of Civilization From Primates to Robots BY IAN MORRIS. Farrar, Straus and Giroux, 2014, 512 pp. $30.00.
The philosopher Alfred North Whitehead once remarked that the history of European philosophy consists of a series of footnotes to Plato.

A HISTORY OF VIOLENCE
Morris’ account begins 10,000 years ago, in the Stone Age, when the planet’s several million human inhabitants lived in small, warring bands of hunter-gatherers. In this unhappy era, by admittedly very rough estimates, between ten and 20 percent of all people could expect to die violently at the hands of others. Over the next five millennia, conditions improved thanks to the first great change in the history of the human species: the advent of agriculture and the development of large,
