Why do human beings behave as they do?
We are able to savage acts of violence but in addition spectacular feats of kindness: is one side of our nature destined to win out over the other?
Every act of human behaviour has a couple of layers of causation, spiralling back seconds, minutes, hours, days, months, years, even centuries, right back to the daybreak of time and the origins of our species.
