Cicero, Academica 4.10
“Certainly, while you may introduce a probable case, when those who are educated will prefer to read in Greek and those who do not understand will fail to read these things too, tell me, do you make your case enough? The fact is that those who could not read Greek and those who can will not dismiss the works of their own language. Truly, why would educated Greeks read Latin poets but not read Latin philosophers?
Perhaps it is because Ennius, Pacuvius, Attius and many others delight them because they have conveyed not the words of the Greeks but their power? How much more will philosophers please them, if they imitate Plato, Aristotle and Theophrastus the way our poets have Aeschylus, Sophocles, and Euripides? I notice that some of our orators who have followed Hyperides and Demosthenes are praised for it.”
Causam autem probabilem tu quidem adfers, aut enim Graeca legere malent qui erunt eruditi, aut ne haec quidem qui illa nesciunt; sed da mihi nunc—satisne probas? Immo vero et haec qui illa non poterunt et qui Graeca poterunt non contemnent sua. Quid enim causae est cur poëtas Latinos Graecis litteris eruditi legant, philosophos non legant? An quia delectat Ennius, Pacuvius, Attius, multi alii, qui non verba sed vim Graecorum expresserunt poëtarum? Quanto magis philosophi delectabunt, si, ut illi Aeschylum, Sophoclem, Euripidem, sic hi Platonem imitentur, Aristotelem, Theophrastum? Oratores quidem laudari video, si qui e nostris Hyperidem sint aut Demosthenem imitati.
