And all knowledge, when separated from justice and virtue, is seen to be cunning and not wisdom; wherefore make this your first and last and constant and all-absorbing aim, to exceed, if possible, not only us but all your ancestors in virtue; and know that to excel you in virtue only brings us shame, but that to be excelled by you is a source of happiness to us.
PlatoFor though a man should be a complete unbeliever in the being of gods; if he also has a native uprightness of temper, such persons will detest evil in men; their repugnance to wrong disinclines them to commit wrongful acts; they shun the unrighteous and are drawn to the upright.
PlatoUntil philosophers rule as kings or those who are now called kings and leading men genuinely and adequately philosophise, that is, until political power and philosophy entirely coincide, while the many natures who at present pursue either one exclusively are forcibly prevented from doing so, cities will have no rest from evils,... nor, I think, will the human race.
