2 In consideration of this, I have frequently held my tongue, and overcome an impatient man with patience; since I could neither teach an unteachable man, nor check an impious one with religion, nor restrain a frantic man with gentleness. But yet, when you say that very many are complaining that to us it is ascribed that wars arise more frequently, that plague, that famines rage, and that long droughts are suspending the showers and rains, it is not fitting that I should be silent any longer, lest my silence should begin to be attributed to mistrust rather than to modesty; and while I am treating the false charges with contempt, I may seem to be acknowledging the crime. I reply, therefore, as well to you, Demetrianus, as to others whom perhaps you have stirred up, and many of whom, by sowing hatred against us with malicious words. you have made your own partisans, from the budding forth of your own root and origin, who, however, I believe, will admit the reasonableness of my discourse; for he who is moved to evil by the deception of a lie, will much more easily be moved to good by the cogency of truth.
