But to enable a prince to form an opinion of his servant there is one test which never fails; when you see the servant thinking more of his own interests than of yours, and seeking inwardly his own profit in everything, such a man will never make a good servant, nor will you ever be able to trust him; because he who has the state of another in his hands ought never to think of himself, but always of his prince, and never pay any attention to matters in which the prince is not concerned. On the other hand, to keep his servant honest the prince ought to study him, honouring him, enriching him, doing him kindnesses, sharing with him the honours and cares; and at the same time let him see that he cannot stand alone, so that many honours may not make him desire more, many riches make him wish for more, and that many cares may make him dread chances. When, therefore, servants, and princes towards servants, are thus disposed, they can trust each other, but when it is otherwise, the end will always be disastrous for either one or the other. CHAPTER XXIII. HOW FLATTERERS SHOULD BE AVOIDED I do not wish to leave out an important branch of this subject, for it is a danger from which princes are with difficulty preserved, unless they are very careful and discriminating. It is that of flatterers, of whom courts are full, because men are so self-complacent in their own affairs, and in a way so deceived in them, that they are preserved with difficulty from this pest, and if they wish to defend themselves they run the danger of falling into contempt. Because there is no other way of guarding oneself from flatterers except letting men understand that to tell you the truth does not offend you; but when every one may tell you the truth, respect for you abates. Therefore a wise prince ought to hold a third course by choosing the wise men in his state, and giving to them only the liberty of speaking the truth to him, and then only of those things of which he inquires, and of none others; but he ought to question them upon everything, and listen to their opinions, and afterwards form his own conclusions. With these councillors, separately and collectively, he ought to carry himself in such a way that each of them should know that, the more freely he shall speak, the more he shall be preferred; outside of these, he should listen to no one, pursue the thing resolved on, and be steadfast in his resolutions. He who does otherwise is either overthrown by flatterers, or is so often changed by varying opinions that he falls into contempt.
