Why, why are people all balls of bitter dust? Because they won't fall off the tree when they're ripe. They hang on to their old positions when the position is overpast, till they become infested with little worms and dry-rot.
Those persons are happiest in this restless and mutable world who are in love with change, who delight in what is new simply because it differs from what is old; who rejoice in every innovation, and find a strange alert pleasure in all that is, and that has never been before.
It is the free alone which never changes, and the unchangeable alone which is free; for change is produced by something exterior to a thing, or within itself, which is more powerful than the surroundings.
