I have long held that the greatest tragedy, among countless misfortunes that recur in the long and agonizing human story, is not when evil triumphs over good, or when oppression overcomes freedom, or even the wretched loss of ten billion potential might-have-beens. No, the most devastating defect in our character -- a trait that held us down ever since the caves -- is the very same twist in our natures that makes us such fine storytellers. I am talking about our incredible penchant for -- and creativity at -- self delusion and rationalization. The lengths that we all go to, in order to convince ourselves that we are the smart ones, virtuous and right... often in complete denial of blatant evidence to the contrary. It is the one magical act that all of us can easily perform, at near genius level.
