… is from page 131 of H.L. Mencken’s A Second Mencken Chrestomathy (1995):
The curse of man, and the cause of his worst woes, is his stupendous capacity for believing the incredible. He is forever embracing delusions, and each new one is more preposterous than all that have gone before.
DBx: Indeed so. We human beings are just intelligent enough to delude ourselves into believing the absurd to be obvious and the obvious to be absurd. And as Mencken says, this condition is indeed a curse.
