It is graceful in a man to think and to speak with propriety, to act with deliberation, and in every occurrence of life to find out and persevere in the truth. On the other hand, to be imposed upon, to mistake, to falter, and to be deceived, is as ungraceful as to rave or to be insane.

No one has leave to sin.

Peace is liberty in tranquillity.
