【正文】 assured that there are two things which lead men tobelieve in the Gods, as we have already stated? Cle. What are they? Ath. One is the argument about the soul, which has been alreadymentionedthat it is the eldest, and most divine of all things, towhich motion attaining generation gives perpetual existence。 the otherwas an argument from the order of the motion of the stars, and ofall things under the dominion of the mind which ordered theuniverse . If a man look upon the world not lightly or substances, and to these theyassigned the causes of all things. Such studies gave rise to muchatheism and perplexity, and the poets took occasion to beabusive paring the philosophers to shedogs uttering vain howlings,and talking other nonsense of the same sort. But now, as I said, thecase is reversed. Cle. How so? Ath. No man can be a true worshipper of the Gods who does not know these two principlesthat the soul is the eldest of all things whichare born, and is immortal and rules over all bodies。 moreover, as Ihave now said several times, he who has not contemplated the mind ofnature which is said to exist in the stars, and gone through theprevious training, a nd seen the connection of music with these things,and harmonized them all w ith laws and institutions, is not able togive a reason of such things as have a reason. And he who is unable toacquire this in addition to the ordinary virtues of a citizen, canhardly be a good ruler of a whole state。 but he should be thesubordinate of other rulers. Wherefore, Cleinias and Megillus, letus consider whether we may not add to all the other laws which we havediscussed this further onethat the nocturnal assembly of themagistrates, which has also shared in the whole scheme of educationproposed by us, shall be a guard set according to law for thesalvation of the state. Shall we propose this? Cle. Certainly, my good friend, we will if the thing is in anydegree possible. Ath. Let us make a mon effort to gain such an object。 for I toowill gladly share in the attempt. Ath. In the first place, a list would have to be made out of thosewho by their ages and studies and dispositions and habits are wellfitted for the duty of a guardian. In the next place, it w ill not beeasy for them to discover themselves what they ought to learn, orbee the disciple of one whor the city。 none of the present pany oflegislators, as I may call them, would hesitate about that. And thestate will be perfected and bee a waking reality, which a littlewhile ago we attempted to create as a dream and in idea only, minglingto gether reason and mind in one image, in the hope that our citizensmight be duly mingled and rightly educated。 and being educated, anddwelling in the citadel of the land, might bee perfect guardians,such as we have never seen ionship and right, as we enactedbefore. Now we must not conceal from ourselves that such laws areapt to be oppressive and that there may sometimes be a hardship in thelawgiver c ommanding the kinsman of the dead man to marry his relation。be may be thought not to have considered the innum erable hindranceswhich may arise among men in the execution of such ordinances。 forthere may be cases in which the parties re fuse to obey, and areready to do anything rather than marry, when there is some bodily ormental malady or defect among those who are bidden to marry or bemarried. Persons may fancy that the legislator never thought ofthis, but they are mistaken。 wherefore let us ma ke a mon prelude onbehalf of the lawgiver and of his subjects, the law begging the latterto f ive the legislator, in that he, having to take care of themon weal, cannot order at the same time the various circumstancesof individuals, and begging him to pardon them if naturally they aresometimes unable to fulfil the act which he in his ignorance imposesupon them. Cle. And how, Stranger, can we act most fairly under thecircumstances? Ath. There must be arbiters chosen to deal with such laws and thesubjects of them. Cle. What do you mean? Ath. I mean to say, that a case may occur in which the nephe w,having a rich father, will be unw illing to marry the daughter of hisuncle。 he w ill have a feeling of pride, and he will wish to lookhigher. And there are cases in which the legislator w ill be imposingupon him the greatest calamity, and he w ill be pelled to disobeythe law, if he is required, for example, to take a w ife who is mad, orhas some other terrible malady of soul or body, such as makes lifeintolerable to the sufferer. Then let what we are saying concerningthese c ases be embodied in a law:If any one finds fault w ith theestablished laws respecting testaments, both as to other matters andespecially in what relates to marriage, and asserts that thelegislator, if he were alive and present, would not pel him toobey that is to say, would not pel those who are by our lawrequired to marry or be given in marriage, to do eitherand somekinsman or guardian dispute this, the reply is that the legislator left fifteen of the guardians of the law to be arbiters and fathers oforphans, male or female, and to them let the disputants have recourse,and by their aid determine any matters of the kind, admitting theirdecision to be final. But if any one thinks that too great power isthus given to the guardians of the la w, let him bring hisadversaries into the court of the select judges, and there have thepoints in dispute determined. And he who loses the cause shall havecensure and blame from the legislator, which, by a man of sense, isfelt to be a penalty far heavier than a great loss of money. Thus will orphan children have a second birth. After their f irstbirth we spoke of their nurture and education, and after theirsecond birth, when they have lost their parents, we ought to ta kemeasures that the misfortune of orphanhood may be as little sad tothem as possible. In the first place, we say that the guardian
