“ Man's life, as required by his nature, is not the life of a mindless brute, of a looting thug or a mooching mystic, but the life of a thinking being—not life by means of force or fraud, but life by means of achievement—not survival at any price, since there's only one price that pays for man's survival: reason. ”
 Ayn Rand, Atlas Shrugged (1957). copy citation
