How can it dwell where, as Plato says, continual Becoming and never Being is the sole form of existence? In the first place, a man never is happy, but spends his whole life in striving after something which he thinks will make him so; he seldom attains his goal, and when he does, it is only to be disappointed; he is mostly shipwrecked in the end, and comes into harbour with masts and rigging gone.
