Histories

This, O king, is my advice to you. But you, Mardonius son of Gobryas, cease your foolish words about the Greeks, for they do not deserve to be maligned. By slandering the Greeks you incite the king to send this expedition; that is the end to which you press with all eagerness. Let it not be so.

Slander is a terrible business; there are two in it who do wrong and one who suffers wrong. The slanderer wrongs another by accusing an absent man, and the other does wrong in that he is persuaded before he has learned the whole truth; the absent man does not hear what is said of him and suffers wrong in the matter, being maligned by the one and condemned by the other.
