Off. 1.13.1Atque etiam sī quid singulī temporibus adductī hostī prōmīsērunt, est in eō ipsō fidēs cōnservanda, ut prīmō Pūnicō bellō Rēgulus captus ā Poenīs cum dē captīvīs commūtandīs Rōmam missus esset iūrāssetque sē reditūrum, prīmum, ut vēnit, captīvōs reddendōs in senātū nōn cēnsuit, deinde, cum retinērētur ā propinquīs et ab amīcīs, ad supplicium redīre māluit quam fidem hostī datam fallere.Also, if individuals, led by circumstances, have promised anything to the enemy, good faith must be kept even in that very matter, as in the First Punic War Regulus, captured by the Carthaginians, when he had been sent to Rome to negotiate an exchange of prisoners and had sworn that he would return, first, as soon as he came, proposed in the senate that the prisoners should not be returned, and then, when he was held back by his relatives and friends, chose to return to execution rather than break the faith he had given to the enemy. Off. 1.13.41Ac dē bellicīs quidem officiīs satis dictum est.And enough has been said about the duties of war. Off. 1.13.41Meminerīmus autem etiam adversus īnfimōs iūstitiam esse servandam.Let us remember, moreover, that justice must be maintained even towards the lowest.
Off. 1.13.41Est autem īnfima condiciō et fortūna servōrum, quibus nōn male praecipiunt quī ita iubent ūtī, ut mercennāriīs: operam exigendam, iūsta praebenda.Now the lowest condition and fortune is that of slaves, regarding whom those give sound advice who bid us treat them as hired labourers: work is to be required of them, and their due provided. Off. 1.13.41Cum autem duōbus modīs, id est aut vī aut fraude, fīat iniūria, fraus quasi vulpēculae, vīs leōnis vidētur;Since wrong is done in two ways, that is, either by force or by fraud, fraud seems to belong to the little fox, force to the lion; Off. 1.13.41utrumque homine aliēnissimum, sed fraus odiō digna maiōre.both are utterly foreign to man, but fraud deserves the greater hatred. Off. 1.13.41Tōtīus autem iniūstitiae nūlla capitālior quam eōrum, quī tum, cum maximē fallunt, id agunt, ut virī bonī esse videantur.But of all injustice none is more deadly than that of those who, at the very moment when they are most deceiving, act so as to seem good men. Off. 1.13.41Dē iūstitiā satis dictum.Enough has been said about justice.
