The vices are very justly man's executioners. - Vicesimus Knox

God commands (people) to maintain justice, kindness, and proper relations with their relatives. He forbids them to commit indecency, sin, and rebellion.

The vices of which we are full we carefully hide from others, and we flatter ourselves with the notion that they are small and trivial; we sometimes even embrace them as virtues.

To flee vice is the beginning of virtue, and to have got rid of folly is the beginning of wisdom.
