Moral Letters to Lucilius Section 4

Adice nunc, quod quae veritati operam dat oratio, inconposita esse debet et simplex. Haec popularis nihil habet veri; movere vult turbam et inconsultas aures inpetu rapere, tractandam se non praebet, aufertur. Quomodo autem regere potest, quae regi non potest? Quid, quod haec oratio, quae sanandis mentibus adhibetur, descendere in nos debet? Remedia non prosunt, nisi inmorantur.

Ajoute que l’éloquence qui se consacre à la vérité doit être simple et sans apprêt, tandis que la
faconde populaire n’a rien de vrai. Elle veut remuer la foule, et entraîner tout d’un élan un auditoire sans expérience : elle ne se laisse pas examiner, elle est déjà loin. Or comment modérer les autres, quand on ne peut se modérer ? D’ailleurs le discours qui s’emploie à la guérison des âmes doit pénétrer tout l’homme :

Besides, speech that deals with the truth should be unadorned and plain. This popular style has nothing to do with the truth; its aim is to impress the common herd, to ravish heedless ears by its speed; it does not offer itself for discussion, but snatches itself away from discussion. But how can that speech govern others which cannot itself be governed? May I not also remark that all speech which is employed for the purpose of healing our minds, ought to sink into us? Remedies do not avail unless they remain in the system.
