“Some people are so extremely whiffling and inconsiderable that they are as far from any real faults as from substantial virtues.”
—François, Duc De La Rochefoucauld (1613–1680)
“The money complex is the demonic, and the demonic is God’s ape; the money complex is therefore the heir to and substitute for the religious complex, an attempt to find God in things.”
