Once we accept violence as an adaptation, it makes sense that its expression is calibrated to the environment. The same individual will behave differently if he comes of age in Detroit, Mich., versus Windsor, Ontario; in New York in the 1980s versus New York now; in a culture of honor versus a culture of dignity.

The irrationality of disgust suggests it is unreliable as a source of moral insight. There may be good arguments against gay marriage, partial-birth abortions and human cloning, but the fact that some people find such acts to be disgusting should carry no weight.

If our wondrous kindness is evidence for God, is our capacity for great evil proof of the Devil?

Paul Bloom Quotes
