"The wisest man may be wiser to-day than he was yesterday, and to-morrow than he is to-day. Total freedom from change would imply total freedom from error; but this is the prerogative of Omniscience alone. The world, however, are very censorious, and will hardly give a man credit for simplicity and singleness of heart, who is not only in the habit of changing his opinions, but also of bettering his fortunes by every change."
