But enough of this. For I have written again and again for your encouragement. Let us now return to the remaining section of our subject as outlined.
Panaetius on Moral Duties.
7 Panaetius, then, has given us what is unquestionably the most thorough discussion of moral duties that we have, and I have followed him in the main—but with slight modifications. He classifies under three general heads the ethical problems which people are accustomed to consider and weigh: first, the question whether the matter in hand is morally right or morally wrong; second, whether it is expedient or inexpedient; third, how a decision ought to be reached, in case that which has the appearance of being morally right clashes with that which seems to be expedient. He has treated the first two heads at length in three books; but while he has stated that he meant to discuss the third head in its proper turn, he has never fulfilled his promise. 8 And I wonder the more at this, because Posidonius, a pupil of his, records that Panaetius was still alive thirty years after he published those three books. And I am surprised that Posidonius has but briefly touched upon this subject in certain memoirs of his, and especially, as he states that there is no other topic in the whole range of philosophy so essentially important as this.
Why Panaetius omitted the "Conflict" of the moral and the expedient.
9 Now, I cannot possibly accept the view of those who say that that point was not overlooked but purposely omitted by Panaetius, and that it was not one that ever needed discussion, because there never can be such a thing as a conflict between expediency and moral rectitude. But with regard to this assertion, the one point may admit of doubt—whether that question which is third in Panaetius's classification ought to have been included or omitted altogether; but the other point is not open to debate—that it was included in Panaetius's plan but left unwritten. For if a writer has finished two divisions of a threefold subject, the third must necessarily remain for him to do. Besides, he promises at the close of the third book that he will discuss this division also in its proper turn. 10 We have also in Posidonius a competent witness to the fact. He writes in one of his letters that Publius Rutilius Rufus, who also was a pupil of Panaetius's, used to say that "as no painter had been found to complete that part of the Venus of Cos which Apelles had left unfinished (for the beauty of her face made hopeless any attempt adequately to represent the rest of the figure), so no one, because of the surpassing excellence of what Panaetius did complete, would venture to supply what he had left undone."
11 III. Quam ob rem de iudicio Panaeti dubitari non potest; rectene autem hanc tertiam partem ad exquirendum officium adiunxerit an secus, de eo fortasse disputari potest. Nam, sive honestum solum bonum est, ut Stoicis placet, sive, quod honestum est, id ita summum bonum est, quem ad modum Peripateticis vestris videtur, ut omnia ex altera parte collocata vix minimi momenti instar habeant, dubitandum non est, quin numquam possit utilitas cum honestate contendere. Itaque accepimus Socratem exsecrari solitum eos, qui primum haec natura cohaerentia opinione distraxissent. Cui quidem ita sunt Stoici assensi, ut et, quicquid honestum esset, id utile esse censerent nec utile quicquam, quod non honestum.
12 Quodsi is esset Panaetius, qui virtutem propterea colendam diceret, quod ea efficiens utilitatis esset, ut ii, qui res expetendas vel voluptate vel indolentia metiuntur, liceret ei dicere utilitatem aliquando cum honestate pugnare; sed cum sit is, qui id solum bonum iudicet, quod honestum sit, quae autem huic repugnent specie quadam utilitatis, eorum neque accessione meliorem vitam fieri nec decessione peiorem, non videtur debuisse eius modi deliberationem introducere, in qua, quod utile videretur, cum eo, quod honestum est, compararetur. 13 Etenim quod summum bonum a Stoicis dicitur, convenienter naturae vivere, id habet hanc, ut opinor, sententiam: cum virtute congruere semper, cetera autem, quae secundum naturam essent, ita legere, si ea virtuti non repugnarent. Quod cum ita sit, putant quidam hanc comparationem non recte introductam, nec omnino de eo genere quicquam praecipiendum fuisse.
Atque[273] illud quidem honestum, quod proprie vereque dicitur, id in sapientibus est solis neque a virtute divelli umquam potest; in iis autem, in quibus sapientia perfecta non est, ipsum illud quidem perfectum honestum nullo modo, similitudines honesti esse possunt. 14 Haec enim officia, de quibus his libris disputamus, media Stoici appellant; ea communia sunt et late patent; quae et ingenii bonitate multi assequuntur et progressione discendi. Illud autem officium, quod rectum idem appellant, perfectum atque absolutum est et, ut idem dicunt, omnes numeros habet nec praeter sapientem cadere in quemquam potest. 15 Cum autem aliquid actum est, in quo media officia compareant,[274] id cumulate videtur esse perfectum, propterea quod volgus, quid absit a perfecto, non fere intellegit; quatenus autem intellegit, nihil putat praetermissum; quod idem[275] in poematis, in picturis usu venit in aliisque compluribus, ut delectentur imperiti laudentque ea, quae laudanda non sint, ob eam, credo, causam, quod insit in iis[276] aliquid probi, quod capiat ignaros, qui quidem,[277] quid in una quaque re vitii sit, nequeant iudicare; itaque, cum sunt docti a peritis, desistunt facile sententia.
The conflict between Expediency and Moral Rectitude only apparent.
11 III. In regard to Panaetius's real intentions, therefore, no doubt can be entertained. But whether he was or was not justified in adding this third division to the inquiry about duty may, perhaps, be a matter for debate. For whether moral goodness is the only good, as the Stoics believe, or whether, as your Peripatetics think, moral goodness is in so far the highest good that everything else gathered together into the opposing scale would have scarcely the slightest weight, it is beyond question that expediency can never conflict with moral rectitude. And so, we have heard, Socrates used to pronounce a curse upon those who first drew a conceptual distinction between things naturally inseparable. With this doctrine the Stoics are in agreement in so far as they maintain that if anything is morally right, it is expedient, and if anything is not morally right, it is not expedient.
