Fortune never helps the fainthearted.
What men have seen they know. . . .
A man though wise, should never be ashamed of learning more, and must unbend his mind.
Wisdom is a dreadful thing when it brings no knowledge to its possessor.
Whoe'er imagines prudence all his own, Or deems that he hath powers to speak and judge Such as none other hath, when they are known, They are found shallow.
Despair often breeds disease.
