How is Sir Pol different than Volpone?

Sir Politic is a knight and traveler from England, who prides himself on knowing the ways of a gentleman. He is a know-it-all who in fact knows not very much at all. He puts tremendous stake in his reputation and in many ways acts as a foil for Volpone. Unlike Volpone's, however, Sir Politic's get-rich-quick schemes are not exploitative.
