Now we have a right to claim, as you yourself allowed, in thematter of laws, that before you are hard upon us and threaten us,you should argue with us and convince usyou should f irst attempt toteach and persuade us that there are Gods by reasonable evidences, andalso that they are too good to be unrighteous, or to be propitiated,or turned from the ir course by gifts. For when we hear such thingssaid of them by those who are esteemed to be the best of poets, andorators, and prophets, and priests, and by innumerable others, thethoughts of most of us are not set upon abstaining from unrighteousacts, but upon doin g them and atoning for them. When lawgivers professthat they are gentle and not stern, we think that they should f irst ofall use persuasion to us, and show us the existence of Gods, if not ina better manner than other men, at any rate in a truer。 but he who did must have supposed one of threethingseither that they did not exist,which is the first possibility,or secondly, that, if they did, they took no care of man, orthirdly, that they were easily appeased and turned aside from theirpurpose, by sacrifices and prayers.

If he be inferior, if he be to be mended, you much more。s self hath any perfection. For saith Pliny very wittily。 omnium, quae cHxerat jeceratque, arte quadam ostentator: for that proceeds not of vanity, but of natural magnanimity, and discretion: and in some persons is not only ely, but gracious. For excusations, cessions, modesty itself well governed, are but arts of ostentation. And amongst those arts there is none be tter, than that which Plinius Secundus speaketh of。s memory。 for as iron sharpens iron, so by glory one courage sharpeh another.
