"Knowledge is not wisdom: cleverness is not, not without awareness of our death, not without recalling just how brief our flare is. He who overreaches will, in his overreaching, lose what he possesses, betray what he has now. That which is beyond us, which is greater than the human, the unattainably great, is for the mad, or for those who listen to the mad, and then believe them."
