Sextus Empiricus, Against the Professors 1.1-2
“The schools of Epicurus and Pyrrho seem to have set forth the indictment against the professors of learning (toùs apò tôn mathemátôn) in a cursory way, although not from the same perspective. The Epicureans argue that none of those things that are taught may contribute to wisdom—this is an argument Epicurus made, as some contend, in order to cover up his own lack of education (for Epicurus was criticized by many for his ignorance: he couldn’t even speak correctly in everyday conversation!). In addition, he also antagonistic in this towards Plato and Aristotle, and other similar men, who were versed in many different fields.”
Τὴν πρὸς τοὺς ἀπὸ τῶν μαθημάτων ἀντίρρησιν κοινότερον μὲν διατεθεῖσθαι δοκοῦσιν οἵ τε περὶ τὸν ᾿Επίκουρον καὶ οἱ ἀπὸ τοῦ Πύρρωνος, οὐκ ἀπὸ τῆς αὐτῆς δὲ διαθέσεως, ἀλλ’ οἱ μὲν περὶ τὸν ᾿Επίκουρον ὡς τῶν μαθημάτων μηδὲν συνεργούντων πρὸς σοφίας τελείωσιν, ἤ, ὥς τινες εἰκάζουσι, τοῦτο προκάλυμμα τῆς ἑαυτῶν ἀπαιδευσίας εἶναι νομίζοντες (ἐν πολλοῖς γὰρ ἀμαθὴς ᾿Επίκουρος ἐλέγχεται, οὐδὲ ἐν ταῖς κοιναῖς ὁμιλίαις καθαρεύων), τάχα δὲ καὶ διὰ τὴν πρὸς τοὺς περὶ Πλάτωνα καὶ ᾿Αριστοτέλη καὶ τοὺς ὁμοίους δυσμένειαν πολυμαθεῖς γεγονότας•

Seneca, Moral Epistles 88.20
“Why do we train our children in the liberal arts? It is not because these studies can grant someone virtue, but because they prepare the soul for accepting it.”
“Quare ergo liberalibus studiis filios erudimus?” Non quia virtutem dare possunt, sed quia animum ad accipiendam virtutem praeparant.
Lactantius, Inst. Div. 3.7
“The highest good according to Herillus is knowledge; according to Zeno, to live congruously with nature, and according to some Stoics, to pursue virtue.”
Herilli summum bonum est scientia, Zenonis cum natura congruenter vivere, quorundam Stoicorum virtutem sequi.
