Steven Pinker
Penguin, 2011, 832 pp.

Descrição da editora:

"Violence has been diminishing for millennia and we may be living in the most peaceful time in our species's existence. For most of history, war, slavery, infanticide, child abuse, assassinations, pogroms, gruesome punishments, deadly quarrels, and genocide were ordinary features of life. But today, Pinker shows (with the help of more than a hundred graphs and maps) all these forms of violence have dwindled and are widely condemned. How has this happened?"
