All men are partially buried in the grave of custom, and of some we see only the crown of the head above ground. Better are the physically dead, for they more lively rot. Even virtue is no longer such if it be stagnant. A man's life should be constantly as fresh as this river. It should be the same channel, but a new water every instant.
