*135* The subjects of conversation are usually affairs of the home or politics or the practice of the professions and learning. Accordingly, if the talk begins to drift off to other channels, pains should be taken to bring it back again to the matter in hand--but with due consideration to the company present; for we are not all interested in the same things at all times or in the same degree. We must observe, too, how far the conversation is agreeable and, as it had a reason for its beginning, so there should be a point at which to close it tactfully. *136* XXXVIII. Sed quo modo in omni vita rectissime praecipitur, ut perturbationes fugiamus, id est motus animi nimios rationi non optemperantes, sic eius modi motibus sermo debet vacare, ne aut ira exsistat aut cupiditas aliqua aut pigritia aut ignavia aut tale aliquid appareat, maximeque curandum est, ut eos, quibuscum sermonem conferemus, et vereri et diligere videamur. Obiurgationes etiam non numquam incidunt necessariae, in quibus utendum est fortasse et vocis contentione maiore et verborum gravitate acriore, id agendum etiam, ut ea facere videamur irati. Sed, ut ad urendum et secandum, sic ad hoc genus castigandi raro invitique veniemus nec umquam nisi necessario, si nulla reperietur alia medicina; sed tamen ira procul absit, cum qua nihil recte fieri, nihil considerate potest. *137* Magnam autem partem[133] clementi castigatione licet uti, gravitate tamen adiuncta, ut severitas adhibeatur et contumelia repellatur, atque etiam illud ipsum, quod acerbitatis habet obiurgatio, significandum est, ipsius id causa, qui obiurgetur, esse susceptum. Rectum est autem etiam in illis contentionibus, quae cum inimicissimis fiunt, etiamsi nobis indigna audiamus, tamen gravitatem retinere, iracundiam pellere. Quae enim cum aliqua perturbatione fiunt, ea nec constanter fieri possunt neque iis, qui adsunt, probari. Deforme etiam est de se ipsum praedicare falsa praesertim et cum irrisione audientium imitari militem gloriosum.

But as we have a most excellent rule for every phase of life, to avoid exhibitions of passion, that is, mental excitement that is excessive and uncontrolled by reason; so our conversation ought to be free from such emotions: let there be no exhibition of anger or inordinate desire, of indolence or indifference, or anything of the kind. We must also take the greatest care to show courtesy and consideration toward those with whom we converse. #(1) in reproofs,#
