Famous quotes containing the word designs:
“It is a mighty error to suppose that none but violent and strong passions, such as love and ambition, are able to vanquish the rest. Even idleness, as feeble and languishing as it is, sometimes reigns over them; it usurps the throne and sits paramount over all the designs and actions of our lives, and imperceptibly wastes and destroys all our passions and all our virtues.”
—François, Duc De La Rochefoucauld (1613–1680)
