Now, in the decade of Darfur and Iraq, a statement like that might seem somewhere between hallucinatory and obscene. But I'm going to try to convince you that that is the correct picture. The decline of violence is a fractal phenomenon. You can see it over millennia, over centuries, over decades and over years, although there seems to have been a tipping point at the onset of the Age of Reason in the sixteenth century. One sees it all over the world, although not homogeneously.
