Ben Jonson
Talking and eloquence are not the same thing: to speak, and to speak well, are two things. A fool may talk, but a wise man speaks.
Be not ashamed of thy virtues; honor's a good brooch to wear in a man's hat at all times.
No man is so foolish but he may sometimes give another good counsel, and no man so wise that he may not easily err if he takes no other counsel than his own. He that is taught only by himself has a fool for a master.
Language most shews a man: Speak, that I may see thee.
He knows not his own strength that hath not met adversity.
