Promises are, therefore, sometimes not to be kept; and trusts are not always to be restored. Suppose that a person leaves his sword with you when he is in his right mind, and demands it back in a fit of insanity; it would be criminal to restore it to him; it would be your duty not to do so. Again, suppose that a man who has entrusted money to you proposes to make war upon your common country, should you restore the trust? I believe you should not; for you would be acting against the state, which ought to be the dearest thing in the world to you. Thus there are many things which in and of themselves seem morally right, but which under certain circumstances prove to be not morally right: to keep a promise, to abide by an agreement, to restore a trust may, with a change of expediency, cease to be morally right. With this I think I have said enough about those actions which masquerade as expedient under the guise of prudence, while they are really contrary to justice. *96* Since, however, in Book One we derived moral duties from the four sources of moral rectitude, let us continue the same fourfold division here in pointing out how hostile to virtue are those courses of conduct which seem to be, but really are not, expedient. We have discussed wisdom, which cunning seeks to counterfeit, and likewise justice, which is always expedient. There remain for our discussion two divisions of moral rectitude, the one of which is discernible in the greatness and pre-eminence of a superior soul, the other, in the shaping and regulation of it by temperance and self-control. *97* XXVI. Utile videbatur Ulixi, ut quidem poëtae tragici prodiderunt (nam apud Homerum, optimum auctorem, talis de Ulixe nulla suspicio est), sed insimulant eum tragoediae simulatione insaniae militiam subterfugere voluisse. Non honestum consilium, at utile, ut aliquis fortasse dixerit, regnare et Ithacae vivere otiose cum parentibus, cum uxore, cum filio. Ullum tu decus in cotidianis laboribus et periculis cum hac tranquillitate conferendum putas? Ego vero istam contemnendam et abiciendam, quoniam, quae honesta non sit, ne utilem quidem esse arbitror. *98* Quid enim auditurum putas fuisse Ulixem, si in illa simulatione perseveravisset? qui cum maximas res gesserit in bello, tamen haec audiat ab Aiace: #(Accius or Pacuvius, Judicium Armorum?) _Inc. inc. fab._, Ribbeck^2 55-60# Cuius ípse princeps iúris iurandí fuit, Quod ómnes scitis, sólus neglexít fidem; Furere ássimulare, né coiret, ínstitit. Quodní Palamedi pérspicax prudéntia Istíus percepset[354] málitiosam audáciam, Fidé sacratae[355] iús perpetuo fálleret. *99* Illi vero non modo cum hostibus, verum etiam cum fluctibus, id quod fecit, dimicare melius fuit quam deserere consentientem Graeciam ad bellum barbaris inferendum.
