Those who gave thee a body, furnished it with weakness; but He who gave thee Soul, armed thee with resolution. Employ it, and thou art wise; be wise and thou art happy. 630
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. 638
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. 651
