*56* In this way, then, in certain doubtful cases moral rectitude is defended on the one side, while on the other side the case of expediency is so presented as to make it appear not only morally right to do what seems expedient, but even morally wrong not to do it. This is the contradiction that seems often to arise between the expedient and the morally right. #Cicero's decision in the cases.# But I must give my decision in these two cases; for I did not propound them merely to raise the questions, but to offer a solution. *57* I think, then, that it was the duty of that grain dealer not to keep back the facts from the Rhodians, and of this vendor of the house to deal in the same way with his purchaser. The fact is that merely holding one's peace about a thing does not constitute concealment, but concealment consists in trying for your own profit to keep others from finding out something that you know, when it is for their interest to know it. And who fails to discern what manner of concealment that is and what sort of person would be guilty of it? At all events he would be no candid or sincere or straightforward or upright or honest man, but rather one who is shifty, sly, artful, shrewd, underhand, cunning, one grown old in fraud and subtlety. Is it not inexpedient to subject oneself to all these terms of reproach and many more besides? *58* XIV. Quodsi vituperandi, qui reticuerunt, quid de iis existimandum est, qui orationis vanitatem adhibuerunt? C. Canius, eques Romanus, nec infacetus et satis litteratus, cum se Syracusas otiandi, ut ipse dicere solebat, non negotiandi causa contulisset, dictitabat[315] se hortulos aliquos emere velle, quo invitare amicos et ubi se oblectare sine interpellatoribus posset. Quod cum percrebruisset, Pythius ei quidam, qui argentariam faceret Syracusis, venales quidem se hortos non habere, sed licere uti Canio, si vellet, ut suis, et simul ad cenam hominem in hortos invitavit in posterum diem. Cum ille promisisset, tum Pythius, qui esset ut argentarius apud omnes ordines gratiosus, piscatores ad se convocavit et ab iis petivit, ut ante suos hortulos postridie piscarentur, dixitque, quid eos facere vellet. Ad cenam tempori[316] venit Canius; opipare a Pythio apparatum convivium, cumbarum ante oculos multitudo; pro se quisque, quod ceperat, afferebat, ante pedes Pythi pisces abiciebantur. *59* Tum Canius: "Quaeso," inquit, "quid est hoc, Pythi? tantumne piscium? tantumne cumbarum?" Et ille: "Quid mirum?" inquit, "hoc loco est Syracusis quicquid est piscium, hic aquatio, hac villa isti carere non possunt." Incensus Canius cupiditate contendit a Pythio, ut venderet; gravate ille primo; quid multa? impetrat. Emit homo cupidus et locuples tanti, quanti Pythius voluit, et emit instructos; nomina facit, negotium conficit. Invitat Canius postridie familiares suos, venit ipse mature; scalmum nullum videt, quaerit ex proximo vicino, num feriae quaedam piscatorum essent, quod eos nullos videret.
