Moral Letters to Lucilius Section 13

Adice nunc, quod oratio certam regulam non habet; consuetudo illam civitatis, quae numquam in eodem diu stetit, versat. Multi ex alieno saeculo petunt verba, duodecim tabulas loquuntur. Gracchus illis et Crassus et Curio nimis culti et recentes sunt, ad Appium usque et Coruncanium redeunt. Quidam contra, dum nihil nisi tritum et usitatum volunt, in sordes incidunt.

Ajoute qu’en littérature il n’y a point de règle absolue. On varie au gré des usages sociaux, qui jamais ne restent longtemps les mêmes.

Nombre de gens exploitent le vocabulaire d’un autre âge : ils parlent la langue des douze tables ; Gracchus, Crassus, Curio sont pour eux trop polis, trop modernes : ils remontent jusqu’à Appius et Coruncanius.

Moreover, style has no fixed laws; it is changed by the usage of the people, never the same for any length of time. Many orators hark back to earlier epochs for their vocabulary, speaking in the language of the Twelve Tables. Gracchus, Crassus, and Curio, in their eyes, are too refined and too modern; so back to Appius and Coruncanius! Conversely, certain men, in their endeavour to main- tain nothing but well-worn and common usages, fall into a humdrum style.
