Each man has other motives, of more importance to him, and thereby you are often led astray,—compassion, jealousy, resentment, good nature, and a thousand more. For even though a man escape every other danger, he can never wholly escape those who do not want such a person as he is to exist. But, little by little, by accumulation of these errors the foundation is sapped, and the integrity of public life collapses.
Do not, men of Athens, give way to these motives today. Do not acquit the man who has done you such grievous wrong. Think of the story that will be told, if you do acquit him. Once upon a time certain ambassadors went from Athens to see Philip, and their names were Philocrates, Aeschines, Phryno, and Demosthenes. One of them not only made no gain from his mission, but delivered captives at his own expense; but another went about buying harlots and fish with the money for which he had sold his country.
