Cicero, De Finibus 1.64
“A subject remains which is especially important to this debate, that is friendship which, as you believe, will completely disappear if pleasure is the greatest good. Concerning friendship, Epicurus himself says that of all the paths to happiness wisdom has prepared, there is none greater, more productive, or more enchanting than this one. And he did not advocate for friendship in speech alone but much more through his life, his deeds and his customs.
Myths of the ancients illustrate how great friendship is—in those tales however varied and numerous you seek from the deepest part of antiquity and you will find scarcely three pairs of friends, starting with Theseus and up to Orestes. But, Epicurus in one single and quite small home kept so great a crowd of friends united by the depth of their love. And this is still the practice among Epicureans.”
XX Restat locus huic disputationi vel maxime necessarius, de amicitia, quam si voluptas summum sit bonum affirmatis nullam omnino fore; de qua Epicurus quidem ita dicit, omnium rerum quas ad beate vivendum sapientia comparaverit nihil esse maius amicitia, nihil uberius, nihil iucundius. Nec vero hoc oratione solum sed multo magis vita et factis et moribus comprobavit. Quod quam magnum sit fictae veterum fabulae declarant, in quibus tam multis tamque variis, ab ultima antiquitate repetitis, tria vix amicorum paria reperiuntur, ut ad Orestem pervenias profectus a Theseo. At vero Epicurus una in domo, et ea quidem angusta, quam magnos quantaque amoris conspiratione consentientes tenuit amicorum greges! quod fit etiam nunc ab Epicureis.
