Ben Johnson

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.
Ben Johnson - Timber; or, Discoveries Made Upon Men and Matter
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.

- Ben Johnson
