Moral Letters to Lucilius Section 3

Haec societas diligenter et sancte observata, quae nos homines hominibus miscet et iudicat aliquod esse commune ius generis humani, plurimum ad illam quoque, de qua loquebar, interiorem societatem amicitiae colendam proficit. Omnia enim cum amico communia habebit, qui multa cum homine.

L’exacte et religieuse observation de cette loi sociale qui fait que tous se confondent avec tous, qui proclame l’existence du droit commun de l’humanité, soutient puissamment aussi cette société plus intime dont je parle, qui est l’amitié. Tout sera commun entre amis, si presque tout l’est d’homme à homme.

This fellowship, maintained with scrupulous care, which makes us mingle as men with our fellow-men and holds that the human race have certain rights in common, is also of great help in cherishing the more intimate fellowship which is based on friendship, concerning which I began to speak above. For he that has much in common with a fellow-man will have all things in common with a friend.
