Against Philon, On his Scrutiny

Now you will recognize that the contest will be an unequal one: my resources will not be so ample for showing up his character as his were for contriving his villainies. Nevertheless, if I should not altogether discharge my part in speaking to the accusation, it would not be right that he should benefit by that, but rather that he should be rejected on the score of any points that I can demonstrate to your satisfaction.

For my speech will be found defective only on account of my imperfect acquaintance with the whole of his actions, but adequate on account of the vileness of all his ways. And I also call upon those among you who may have more ability in speaking than I to amplify my exposure of his offences, and to make use of any points that I omit for accusing Philon, in your turn, of offences known to you. For it is not from my sole statement that you ought to form your views of his character.
