"Why do we want to prove them wrong? Because we need them to be wrong. For if they are wrong, and we are right, then our untruth becomes truth: our selfishness becomes justice and virtue: our cruelty and lust cannot be fairly condemned. We can rest secure in the fiction we have determined to embrace as 'truth.' What we desire is not the truth, but rather that our lie should be proved 'right,' and our iniquity be vindicated as 'just.' This is what we have done to pervert our natural, instinctive appetite for truth.
"No wonder we hate. No wonder we are violent. No wonder we exhaust ourselves in preparing for war! And in doing so, of course, we offer the enemy another reason to believe that he is right, that he must arm, that he must get ready to destroy us. Our own lie provides the foundation of truth on which he erects his own lie, and the two lies together react to produce hatred, murder, disaster."
--Thomas Merton, Conjectures of a Guilty Bystander--
