Proverbs 26:11 (King James Version)
Perhaps a lesson for certain politicians who think the Keynesian Economics of yesteryear offer solutions to today's financial woes?
"The study of history is a powerful antidote to contemporary arrogance. It is humbling to discover how many of our glib assumptions, which seem to us novel and plausible, have been tested before, not once but many times and in innumerable guises; and discovered to be, at great human cost, wholly false." -- Paul Johnson
