Letter 4: To Antipater (5-7)

This is the sort of frankness which princes, if they have worthy and fitting greatness of soul, honor as being useful, while those whose natural gifts are weaker than the powers they possess take such frankness ill, as if it forced them to act in some degree contrary to their desires—ignorant as they are that those who dare to speak out most fearlessly in opposition to measures in which expediency is the issue are the very persons who can provide them with more power than others to accomplish what they wish.

For it stands to reason that it is because of those who always and by choice speak to please that not only monarchies cannot endure—since monarchies are liable to numerous inevitable dangers—but even constitutional governments as well, though they enjoy greater security: whereas it is owing to those who speak with absolute frankness in favor of what is best that many things are preserved even of those which seemed doomed to destruction. For these reasons it is indeed fitting that in the courts of all monarches those who declare the truth should be held in greater esteem than those who, though they aim to gratify in all they say, yet say naught that merits gratitude; in fact, however, the former find less favor with some princes.

This experience Diodotus has met with in his relations with some of the potentates of Asia, to whom he had often been of service, not only in offering counsel, but also in venturing upon dangerous deeds; because of his frankness of speech in matters involving their best interests he has been both deprived of honors he had at home and cheated of many hopes elsewhere, and the flattery of men of no consequence had greater weight than his own good services.
