The rulers of the state are the only persons who ought to have the privilege of lying, either at home or abroad; they may be allowed to lie for the good of the state.
PlatoIf there is a good and wise God, then there also exists a progress of humanity toward perfection.
PlatoTrue opinions are a fine thing and do all sorts of good so long as they stay in their place; but they will not stay long. They run away from a man's mind, so they are not worth much until you tether them by working out the reason. Once they are tied down, they become knowledge, and are stable.
Plato
