The essence of a culture of honor is that it does not sanction predatory or instrumental violence, but only retaliation after an insult or other mistreatment.

So holding many factors constant, we find that living in a civilization reduces one’s chances of being a victim of violence fivefold.

Organisms are selected to deploy violence only in circumstances where the expected benefits outweigh the expected costs.

cademics and intellectuals are culture vultures. In a gathering of today’s elite, it is perfectly acceptable to laugh that you barely passed Physics for Poets and Rocks for Jocks and have remained ignorant of science ever since, despite the obvious importance of scientific literacy to informed choices about personal health and public policy. But saying that you have never heard of James Joyce or that you tried listening to Mozart once but prefer Andrew Lloyd Webber is as shocking as blowing your nose on your sleeve or announcing that you employ children in your sweatshop, despite the obvious unimportance of your tastes in leisure-time activity to just about anything.

Challenge a person's beliefs, and you challenge his dignity, standing, and power. And when those beliefs are based on nothing but faith, they are chronically fragile. No one gets upset about the belief that rocks fall down as opposed to up, because all sane people can see it with their own eyes. Not so for the belief that babies are born with original sin or that God exists in three persons or that Ali is the second-most divinely inspired man after Muhammad. When people organize their lives around these beliefs, and then learn of other people who seem to be doing just fine without them--or worse, who credibly rebut them--they are in danger of looking like fools. Since one cannot defend a belief based on faith by persuading skeptics it is true, the faithful are apt to react to unbelief with rage, and may try to eliminate that affront to everything that makes their lives meaningful.

Revenge and retaliation always perpetuate the cycle of anger, fear and violence.
