*109* Then there are others, quite different from these, straightforward and open, who think that nothing should be done by underhand means or treachery. They are lovers of truth, haters of fraud. There are others still who will stoop to anything, truckle to anybody, if only they may gain their ends. Such, we saw, were Sulla and Marcus Crassus. The most crafty and most persevering man of this type was Lysander of Sparta, we are told; of the opposite type was Callicratidas, who succeeded Lysander as admiral of the fleet. So we find that another, no matter how eminent he may be, will condescend in social intercourse to make himself appear but a very ordinary person. Such graciousness of manner we have seen in the case of Catulus--both father and son--and also of Quintus Mucius Mancia. I have heard from my elders that Publius Scipio Nasica was another master of this art; but his father, on the other hand--the man who punished Tiberius Gracchus for his nefarious undertakings--had no such gracious manner in social intercourse [...], and because of that very fact he rose to greatness and fame. Countless other dissimilarities exist in natures and characters, and they are not in the least to be criticized. *110* XXXI. Admodum autem tenenda sunt sua cuique non vitiosa, sed tamen propria, quo facilius decorum illud, quod quaerimus, retineatur. Sic enim est faciendum, ut contra universam naturam nihil contendamus, ea tamen conservata propriam nostram sequamur, ut, etiamsi sint alia graviora atque meliora, tamen nos studia nostra nostrae naturae regula[103] metiamur; neque enim attinet naturae repugnare nec quicquam sequi, quod assequi non queas. Ex quo magis emergit, quale sit decorum illud, ideo quia nihil decet invita Minerva, ut aiunt, id est adversante et repugnante natura. *111* Omnino si quicquam est decorum, nihil est profecto magis quam aequabilitas _cum_[104] universae vitae, tum singularum actionum, quam conservare non possis, si aliorum naturam imitans omittas tuam. Ut enim sermone eo debemus uti, qui innatus[105] est nobis, ne, ut quidam, Graeca verba inculcantes iure optimo rideamur, sic in actiones omnemque vitam nullam discrepantiam conferre debemus. *112* Atque haec differentia naturarum tantam habet vim, ut non numquam mortem sibi ipse consciscere alius debeat, alius [in eadem causa] non debeat.[106] Num enim alia in causa M. Cato fuit, alia ceteri, qui se in Africa Caesari tradiderunt? Atqui ceteris forsitan vitio datum esset, si se interemissent, propterea quod lenior eorum vita et mores fuerant faciliores, Catoni cum incredibilem tribuisset natura gravitatem eamque ipse perpetua constantia roboravisset semperque in proposito susceptoque consilio permansisset, moriendum potius quam tyranni vultus aspiciendus fuit.
