There's a victory and defeat-the first and best of victories, the lowest and worst of defeats-which each man gains or sustains at the hands not of another, but of himself.
PlatoPhysical excellence does not of itself produce a good mind and character: on the other hand, excellence of mind and character will make the best of the physique it is given.
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
