Why seeketh thou revenge, O man! with what purpose is it that thou pursuest it? Thinkest thou to pain thine adversary by it? Know that thou thyself feelest its greatest torments.
Reflection is the business of man; a sense of his state is his first duty: but who remembereth himself in joy? Is it not in mercy then that sorrow is allotted unto us?
To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.
Scorn also to depress thy competitor by any dishonest or unworthy method; strive to raise thyself above him only by excelling him; so shall thy contest for superiority be crowned with honour, if not with success.
True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance.
