A sensible man will remember that the eyes may be confused in two ways - by a change from light to darkness or from darkness to light; and he will recognize that the same thing happens to the soul.
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.
Plato... our purpose in founding our state was not to promote the happiness of a single class, but, so far as possible, of the whole community. Our idea was that we were most likely to justice in such a community, and so be able to decide the question we are trying to answer. We are therefore at the moment trying to construct what we think is a happy community by securing the happiness not of a select minority, but of a whole.
