§109.11

​Etiamnunc sapientis animum perite movere nemo alius potest quam sapiens, sicut hominem movere rationaliter non potest nisi homo. Quomodo ergo ad rationem movendam ratione opus est, sic ut moveatur ratio perfecta, opus est ratione perfecta.

​Furthermore, no one else can skillfully move the mind of a wise man than a wise man, just as nothing can move a human being rationally except a human being. Therefore, just as reason is needed to move reason, so for perfected reason to be moved, perfected reason is needed.

§109.12

​Prodesse dicuntur et qui media nobis largiuntur, pecuniam, gratiam, incolumitatem, alia in usus vitae cara aut necessaria. In his dicetur etiam stultus prodesse sapienti. Prodesse autem est animum secundum naturam movere virtute sua ut eius, qui movebitur.1 Hoc non sine ipsius quoque, qui proderit, bono fiet. Necesse enim alienam virtutem exercendo exerceat et suam.2

​Those also are said to benefit us who lavish upon us indifferent things—money, influence, safety, and other things dear or necessary for the uses of life . In these, even a fool will be said to benefit a wise man. But to benefit is to move the mind according to nature by one’s own virtue, just as by the virtue of the one who is to be moved. This will not happen without the good also of the very one who is to benefit. For of necessity, by exercising another’s virtue, he exercises his own as well.

§109.13

​Sed ut removeas ista, quae aut summa bona sunt aut summorum efficientia, nihilominus prodesse inter se sapientes possunt. Invenire enim sapientem sapienti per se res expetenda est, quia natura bonum omne carum est bono et sic quisque conciliatur bono quemadmodum sibi.

​But though you should remove those things which are either the highest goods or efficient causes of the highest, nevertheless wise men can benefit one another. For to find a wise man is for a wise man a thing to be sought for its own sake, because by nature every good is dear to a good man, and thus everyone is reconciled to a good in the same way as to himself.

§109.14

​Necesse est ex hac quaestione argumenti causa in alteram transeam.3 Quaeritur enim, an deliberaturus sit sapiens, an in consilium aliquem advocaturus. Quod facere illi necessarium est, cum ad haec civilia et domestica venitur et, ut ita dicam, mortalia. In his sic illi opus est alieno consilio quomodo medico, quomodo gubernatori, quomodo advocato et litis ordinatori. Proderit ergo sapiens aliquando sapienti, suadebit enim. Sed in illis quoque magnis ac divinis, ut diximus, communiter honesta tractando et animos cogitationesque miscendo utilis erit.

​Of necessity I must pass from this question to another for the sake of the argument. For it is asked whether a wise man will deliberate, or whether he will call someone into counsel. To do this is necessary for him when it comes to these civil and domestic and, so to speak, mortal affairs. In these he has need of another’s counsel just as of a physician, of a pilot, of an advocate and legal adviser. Therefore a wise man will sometimes benefit a wise man, for he will advise him. But also in those great and divine matters, as we have said, he will be useful by treating honorable things in common and by mixing their minds and thoughts.

§109.15

​Praeterea secundum naturam est et amicos complecti et amicorum auctu ut suo proprioque laetari. Nam nisi hoc fecerimus, ne virtus quidem nobis permanebit, quae exercendo sensu valet, virtus autem suadet praesentia bene conlocare, in futurum consulere, deliberare et intendere animum; facilius intendet explicabitque qui aliquem sibi adsumpserit. Quaeret itaque aut perfectum virum aut proficientem vicinumque perfecto. Proderit autem ille perfectus, si consilium communi prudentia iuverit.

​Furthermore, it is according to nature both to embrace friends and to rejoice in the advancement of friends as if it were one’s own. For unless we do this, not even virtue will remain with us, which is strong by exercising the mind; and virtue advises to lay out present things well, to consult for the future, to deliberate and to direct the mind; he who has taken someone to himself will direct and unfold it more easily. Therefore he will seek either a perfect man or one who is making progress and close to the perfect. And that perfect man will benefit him, if he assists his counsel with their common prudence.

§109.16

​Aiunt homines plus in alieno negotio videre, vitio hoc illis evenit, quos amor sui excaecat quibusque dispectum utilitatis timor in periculis excutit; incipiet sapere securior et extra metum positus. Sed nihilominus quaedam sunt, quae etiam sapientes in alio quam in se diligentius vident. Praeterea illud dulcissimum et honestissimum "idem velle atque idem nolle "sapiens sapienti praestabit; egregium opus pari iugo ducet.

​Men say that they see more in another’s business; this happens to them by a defect, whom self-love blinds and whom fear in dangers shakes out of the discernment of utility; one who is safer and placed outside of fear will begin to be wise. But nevertheless there are certain things which even wise men see more diligently in another than in themselves. Besides, that sweetest and most honorable thing, “to will the same and to nill the same,” a wise man will afford to a wise man; he will draw an excellent work under an equal yoke.

§109.17

​Persolvi id quod exegeras, quamquam in ordine rerum erat, quas moralis philosophiae voluminibus complectimur. Cogita, quod soleo frequenter tibi dicere, in istis nos nihil aliud quam acumen exercere. Totiens enim illo revertor: quid ista me res iuvat? Fortiorem fac iam, iustiorem, temperantiorem. Nondum exerceri vacat; adhuc medico mihi opus est.

​I have paid what you demanded, although it was in the order of things which we embrace in the volumes of moral philosophy. Reflect on what I am accustomed to say to you frequently: in those matters we exercise nothing else than our acumen. For so often do I return thither: how does that thing help me? Make me now braver, more just, more temperate. There is no leisure yet to be exercised; as yet I have need of a physician.

§109.18

​Quid me poscis scientiam inutilem? Magna promisisti; exige, vide. Dicebas intrepidum fore,4 etiam si circa me gladii micarent, etiam si mucro tangeret iugulum; dicebas securum fore, etiam si circa me flagrarent incendia, etiam si subitus turbo toto navem meam mari raperet. Hanc mihi praesta curam, ut voluptatem, ut gloriam contemnam. Postea docebis inplicta solvere, ambigua distinguere, obscura perspicere; nunc doce quod necesse est. VALE.

​Why do you demand of me a useless knowledge? You have promised great things; exact them, see to them. You said that I would be intrepid, even if swords should flash around me, even if a blade should touch my throat; you said that I would be secure, even if fires should blaze around me, even if a sudden tempest should snatch my ship away in the whole sea. Render me this care, so that I may despise pleasure, so that I may despise glory. Afterward you will teach me to solve what is entangled, to distinguish what is ambiguous, to see through what is obscure; now teach what is necessary. FAREWELL.

Syntax notes4 items
  1. 109.12virtute sua ut eius, qui movebitur

    The structure consists of the ablative of means virtute sua without a preposition and the clause introduced by the conjunction ut with an ellipsis ut [virtute] eius. It contrasts the virtue of the agent of movement (virtute sua) with that of the patient (eius = of the one who will be moved).

  2. 109.12Necesse enim alienam virtutem exercendo exerceat et suam

    The impersonal expression necesse [est] directly introduces the subjunctive exerceat without the conjunction ut. The ablative gerund exercendo expresses means, and its logical (and grammatical) subject is that of exerceat (the benefactor).

  3. 109.14Necesse est ex hac quaestione argumenti causa in alteram transeam

    The impersonal verbal phrase necesse est is followed by the present subjunctive transeam (first-person singular) without ut. This omission of ut after necesse est is a standard construction in classical Latin.

  4. 109.18Dicebas intrepidum fore

    An accusative with infinitive (AcI) construction, where the infinitive fore (a contracted form of futurum esse) depends on the main verb dicebas. The subject accusative me is omitted as it is clear from the context (e.g., from the preceding Quid me poscis). The subsequent dicebas securum fore shares the same structure.
