Andtherefore the judges must be men of character, for they will requireboth wisdom and courage。and also it has been the ruin of thetheatre。 and these pleasures are so farfrom being the same, as you describe the Egyptian to be, or having thesame principle s, that they are never the same. Ath. Most true, Cleinias。and, on the other hand, if he have a wealth passing that of Cinyras orMidas, and be unjust, he is wretched and lives in misery? As thepoet says, and with truth: I sing not, I care not about him whoacplishes all noble things, not having justice。 or, again, to be a tyrant and do as youlike 。 and thereupon I proceeded to 。 but not so great, if the bad man lives only a very shorttime. These are the truths which, if I am not mistaken, you willpersuade or c ompel your poets to utter with suitable acpaniments ofharmony and rhythm, and in these they must train up your youth. Am Inot right? For I plainly declare that evils as they are termed aregoods to the unjust, and only evils to the just, and that goods aretruly good to the good, but evil to the evil. Let me ask again, Areyou and I agreed about this? Cle. I think that we partly agree and partly do not. Ath. When a man has health and wealth and a tyranny which lasts, andwhen he is preeminent in strength and courage, and has th e gif t ofimmortality, and none of the socalled evils which counterbalancethese goods, but only the injustice and insolence of his own natureofsuch an one you are, I suspect, unwilling to believe that he ismiserable rather than happy. Cle. That is quite true. Ath. Once more: Suppose that he be valiant and strong, andhandsome and rich, and does throughout his whole life whatever helikes, still, if he be unrighteous and insolent, would not both of youagre e that he will of necessity live basely? You will surely grantso much? Cle. Certainly. Ath. And an evil life too? Cle. I am not equally disposed to grant that. Ath. Will he not live painfully and to his own disadvantage? Cle. How can I possibly say so? Ath. How! Then may Heaven make us to be of one mind, for now weare of tw o. To me, dear Cleinias, the truth of what I am saying isas plain as the fact that Crete is an island. And, if I were alawgiver, I would try to ma ke the poets and all the citizens spea kin this strain, and I would inflict the heaviest penalties on anyone in all the land who should dare to say that there are bad menwho lead pleasant lives, or that the profitable and gainful is ohing, and the just another。 and letno other thing that is called good ever be his. For the goods of whichthe many speak are not really good: f irst in the catalogue is placedhealth, beauty next, wealth third。 and hence there occurreda misapprehension on your part. For when evils are far gone andirremediable, the task of censuring them is never pleasant, althoughat times necessary. But as we do not really differ, will you let meask you whether you consider such institutions to be more prevalentamong the Cretans and Lacedaemonians than among the other Hellenes? Cle. Certainly they are. Ath. And if they were extended to the other Hellenes, would it be animprovement on the present state of things? Cle. A very great improvement, if the customs which prevail amongthem were such as prevail among us and the Lacedaemonians, and such asyou were just now saying ought to prevail. Ath. Let u
