【正文】 ures have more of the ballast, than of the sail. In fame of learning, the flight w ill be slow, without some feathers of ostentation. Q ui de contenmenda gloria libros scribunt, nomen suum inscribunt. Socrates, Aristotle, Galen, were men firil of ostentation. Certainly vainglory helpeth to perpetuate a man\39。s memory。 and virtue was never so beholding to human nature, as it received his due at the second hand. Neither had the fame of Cicero, Seneca, Plinius Secundus, borne her age so well, if it had not been joined with some vanity in themselves: like unto varnish, that makes sealings not only shine, but last But all this while, when I speak of vainglory, I mean not of that property, that Tacitus doth attribute to Mucianus。 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 s peaketh of。 which is to be liberal of praise and mendation to others, in that wherein a man\39。s self hath any perfection. For saith Pliny very wittily。 In mending another, you do your self right。 for he that you mend, is either superior to you, in that you mend, or inferior. If he be inferior, if he be to be mended, you much more。 if he be superior, if he be not to be mended, you much less. Glorious men are the scorn of wise men。 the admiration of fools。 the idols of parasites。 and the slaves of their own vaunts. 第 21 頁 共 19 頁 LastIndexNext And now having spoken of assaults, let us sum up all acts ofviolence under a single law, which shall be as follows:No one shallta ke or carry away any of his neighbour39。s goods, neither shall heuse anything which is his neighbour39。s without the consent of theowner。 for these are the offences which are and have been, and willever be, the source of all the aforesaid evils. The greatest of themare excesses and insolences of youth, and are offences against thegreatest when they are done against religion。 and especially greatwhen in violation of public and holy rites, or of the partly monrites in which tribes and phratries share。 and in the second degreegreat when they are mitted against private rites and sepulchres,and in the third degree (not to repeat the acts formerly mentioned),when insults are offered to parents。 the fourth kind of violence iswhen any one, regardless of the author ity of the rulers, takes orcarries away or makes use of anything which belongs to them, nothaving their consent。 and the f ifth kind is when the violation ofthe civil rights of an individual demands reparation. There shouldbe a mon law embracing all these cases. For we have already said ingeneral terms what shall be the punishment of sacrilege, whetherfraudulent or violent, and now we have to determine what is to bethe punishment of those w ho speak or act insolently toward the G first we must give them an admonition which may be in thefollowing terms:No one who in obedience to the laws believed thatthere were Gods, ever intentionally did any unholy act, or uttered anyunlawful word。 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. Cleinias. What shall we say or do to these persons? Athenian Stranger. My good friend, let us first hear the jests whichI suspect that they in their superiority will utter against us. Cle. What jests? Ath. They will make some irreverent speech of this sort:O inhabitants of A thens, and Sparta, and Cnosus, they will reply, inthat you spea k truly。 for some of us deny the very existence of theGods, w hile others, as you say, are of opinion that they do not careabout us。 and others that they are turned from their course bygifts. 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 manne r than other men, at any rate in a truer。 and whoknows but that we shall hearken to you? If then our request is afair one, please to accept our challenge. Cle. But is there any difficulty in proving the existence of theGods? Ath. How would you prove it? Cle. How ? In the first place, the earth and the sun, and the starsand the universe, and the fair order of the seasons, and thedivision of them into years and months, furnish proof s of theirexistence。 and also there is the fact that all Hellenes and barbariansbelieve in them. Ath. I fear, my sweet friend, though I will not say that I muchregard, the contempt with w hich the profane will be likely to assailus. For you do not understand the nature of their plaint, and youfancy that they rush into impiety only from a love of sensualpleasure. Cle. Why, Stranger, what other reason is there? Ath. One which you who live in a different atmosphere would neverguess. Cle. What is it? Ath. A very grievous sort of ignorance which is imagi
