The better angels of our nature

This riveting, myth-destroying book reveals how, contrary to popular belief, humankind has become progressively less violent, over millenia and decades. Can violence really have declined? The images of conflict we see daily on our screens from around the world suggest this is an almost obscene claim to be making. Extraordinarily, however, Steven Pinker shows violence within and between societies - both murder and warfare - really has declined from prehistory to today.
