*39* Now, in my opinion at least, every walk and vocation in life calls for human co-operation--first and above all, in order that one may have friends with whom to enjoy social intercourse. And this is not easy, unless one is looked upon as a good man. So, even to a man who shuns society and to one who spends his life in the country a reputation for justice is essential--even more so than to others; for they who do not have it [but are considered unjust] will have no defence to protect them and so will be the victims of many kinds of wrong. *40* So also to buyers and sellers, to employers and employed, and to those who are engaged in commercial dealings generally, justice is indispensable for the conduct of business. #Honour among thieves.# Its importance is so great, that not even those who live by wickedness and crime can get on without some small element of justice. For if a robber takes anything by force or by fraud from another member of the gang, he loses his standing even in a band of robbers; and if the one called the "Pirate Captain" should not divide the plunder impartially, he would be either deserted or murdered by his comrades. Why, they say that robbers even have a code of laws to observe and obey. And so, because of his impartial division of booty, Bardulis, the Illyrian bandit, of whom we read in Theopompus, acquired great power, Viriathus, of Lusitania, much greater. He actually defied even our armies and generals. But Gaius Laelius--the one surnamed "the Wise"--in his praetorship crushed his power, reduced him to terms, and so checked his intrepid daring, that he left to his successors an easy conquest. Since, therefore, the efficacy of justice is so great that it strengthens and augments the power even of robbers, how great do we think its power will be in a constitutional government with its laws and courts? *41* XII. Mihi quidem non apud Medos solum, ut ait Herodotus, sed etiam apud maiores nostros iustitiae fruendae causa videntur olim bene morati reges constituti. Nam cum premeretur inops[203] multitudo ab iis, qui maiores opes habebant, ad unum aliquem confugiebant virtute praestantem; qui cum prohiberet iniuria tenuiores, aequitate constituenda summos cum infimis[204] pari iure retinebat.[205] Eademque constituendarum legum fuit causa, quae regum. *42* Ius enim semper est quaesitum aequabile; neque enim aliter esset ius. Id si ab uno iusto et bono viro consequebantur, erant eo contenti; cum id minus contingeret, leges sunt inventae, quae cum omnibus semper una atque eadem voce loquerentur. Ergo hoc quidem perspicuum est, eos ad imperandum deligi solitos, quorum de iustitia magna esset opinio multitudinis. Adiuncto vero, ut idem etiam prudentes haberentur, nihil erat, quod homines iis auctoribus non posse consequi se arbitrarentur. Omni igitur ratione colenda et retinenda iustitia est cum ipsa per sese (nam aliter iustitia non esset), tum propter amplificationem honoris et gloriae.
