Men judge generally more by the eye than by the hand, for everyone can see and few can feel. Every one sees what you appear to be, few really know what you are.
— Nicolo Machiavelli
Il Principe (The Prince), 1515

Quote in Context:
For this reason a prince ought to take care that he never lets anything slip from his lips that is not replete with the above-named five qualities, that he may appear to him who sees and hears him altogether merciful, faithful, humane, upright, and religious. There is nothing more necessary to appear to have than this last quality, inasmuch as men judge generally more by the eye than by the hand, because it belongs to everybody to see you, to few to come in touch with you. Every one sees what you appear to be, few really know what you are, and those few dare not oppose themselves to the opinion of the many, who have the majesty of the state to defend them; and in the actions of all men, and especially of princes, which it is not prudent to challenge, one judges by the result.
