Moral Letters to Lucilius Section 9

Extollere se, quae iustam magnitudinem implevere, non possunt. Quicumque fuerint sapientes, pares erunt et aequales. Habebit unusquisque ex iis proprias dotes: alius erit adfabilior, alius expeditior, alius promptior in eloquendo, alius facundior; illud, de quo agitur, quod beatum facit, aequalest in omnibus.

Tout ce qui a rempli ses proportions naturelles ne peut plus grandir. Tous ceux qui auront atteint la sagesse seront égaux, seront pairs entre eux ; chacun d’eux aura ses qualités à lui : tel sera plus affable ou plus alerte, ou parlera plus facilement, plus éloquemment que tel autre ; mais le point essentiel, mais ce qui fait le bonheur sera égal chez tous.

Things which have reached their full stature cannot grow higher. Men who have attained wisdom will therefore be equal and on the same footing. Each of them will possess his own peculiar gifts: one will be more affable, another more facile, another more ready of speech, a fourth more eloquent; but as regards the quality under discussion, - the element that produces happiness, - it is equal in them all.
