M. Tullius Cicero Divinatio in Q. Caecilium 60

[60] In truth, if you had received ever so many injuries from your praetor, still you would deserve greater credit by bearing them than by revenging them; but when nothing in his life was ever done more rightly than that which you call an injury, shall these judges determine that this cause, which they would not even tolerate in any one else, shall appear in your case to be a reasonable one to justify the violation of your ancient connection? When even if you had received the greatest injury from him, still, since you have been his quaestor, you cannot accuse him and remain blameless yourself. But if no injury has been done you at all, you cannot accuse him without wickedness; and as it is very uncertain whether any injury has been done you, do you think that there is any one of these men who would not prefer that you should depart without incurring blame rather than after having committed wickedness?
