If any one convict in a court of law a stranger or aslave of a theft of public property, let the co urt determine whatpunishment he sha ll suffer, or what penalty he shall pay, bearing inmind that he is probably not incurable. But the citizen w ho has beenbrought up as our citizens w ill have been, if he be found guilty ofrobbing his country by fraud sold anyadulterated goods, in addition to losing the goods themselves, shallbe beaten with stripesa stripe for a drachma, according to theprice of the goods。 and the herald shall proclaim in the agora theoffence for which he is going to be beaten. The warden of the agoraand the guardians of the law shall obtain information from experiencedpersons about the rogueries and adulterations of the sellers, andshall write up what the seller ought and ought not to do in each case。and let them inscribe their laws on a column in front of the courtof the wardens of the agora, that they may be clear instructors ofthose who have business in the agora. Enough has been said in what haspreceded about the wardens of the city, and if anything seems to bewanting, let them municate with the guardians o f the law, and writedow n the omission, and place on a column in the court of the wardensof the city the primary and secondary regulations which are laiddown for them about their office. After the practices of adulteration naturally follow the practicesof retail trade. Concerning these, we will first of all give a word ofcounsel and reason, and the law shall e afterwards. Retail trade ina city is not by nature intended to do any harm, but quite thecontrary。 for is not he a benefactor who reduces the inequalitiesand inco mmensurabilities of goods to equality and mon measure?And this is what the power of money acplishes, and the merchant maybe said to be appointed for this purpose. The hireling and thetavernkeeper, and many other occupations, some of them more andothers less seemly alike have this object。they seek to satisfy ourneeds and equalize our possessions. Let us then endeavour to seewhat has brought retail trade into illodour, and wherein, lies thedishonour and unseemliness of it, in order that if not entirely, wemay yet partially, cure the evil by legislation. To effec t this isno easy matter, and requires a great deal of virtue. Cleinias. What do you mean? Athenian Stranger. Dear Cleinias, the class of men is smalltheymust have been rarely gifted by nature, and trained byeducationwho, when assailed by wants and desires, are able to holdout and observe moderation, and when they might make a great deal ofmoney are sober in their w ishes, and prefer a moderate to a largegain. Bu t the mass of mankind are the very opposite: the ir desires areunbounded, and when they might gain in moderation they prefer gainswithout limit。 wherefore all that relates to retail trade, andmerchandise, and the keeping o f taverns, is denounced and numberedamong dishonourable things. For if what I trust may never be andwill not be, we were to pel, if I may venture to say a ridiculousthing, the best men everywhere to keep taverns for a time, or carry onretail trade, or do anything of that sort。 or if, in consequence ofsome fate or necessity, the best women were pelled to followsimilar callings, t hen we should know how agreeable and pleasant allthese things are。 and if all such occupations were managed onincorrupt principles, they would be honoured as we honour a motheror a nurse. But now that a man g oes to desert places and builds bouseswhich can only be reached be long journeys, for the sa ke of retailtrade, and receives strangers who are in need at the welerestingplace, and gives them peace and calm when they are tossed bythe storm, or cool shade in the heat。 and then instead of behavingto them as friends, and showing the duties of hospitality to hisguests, treats them as enemies and captives who are at his mercy,and will not release them until they have paid the most unjust,abominable, and extortionate ransom these are the sort of practices,and foul evils they are, which cast a reproach upon the succour ofadversity. And the legislator ought always to be devising a remedy forevils of this nature. T here is an ancient saying, which is also a trueone To fight against two opponents is a difficult thing, as isseen in diseases and in many other cases. And in this case also thewar is against two enemieswealth and poverty。 one of whom corruptsthe soul of man with luxury, while the other drives him by pain intoutter shamelessne ss. What remedy can a city of sense find against thisdisease? In the first place, they must have as few retail traders aspossible。 and in the second place, they must assign the oc cupationto that class of men whose corruption w ill be the least injury tothe state。 and in the third place, they must devise some way wherebythe followers of these occupations themselves will not readily fallinto habits of unbridled shamelessness and meann ess. After this preface let our law run as follows, and may fortunefavour us:No landowner among the Mages, w hose city the God isrestoring and resettlingno one, that is, of the 5040 families,shall bee a retail trader either voluntarily or involuntarily。neither shall he be a merchant, or do any service for privatepersons unless they equally serve him, except for his father or hismother, and their fathers and mothers。 and in general for his elderswho are freemen, and whom he serves as a freeman. Now it isdifficult to determine accur ately the things w hich are worthy orunworthy of a freeman, but let those who have obtained the prize ofvirtue give judgment about them in accordance with their feelings ofright and wrong. He who in any way shares in the illib
