Tusculan Disputations 2 ¶3 — Cicero (on the Stoics)

Cicero (on the Stoics), Tusculan Disputations 2 ¶3

But yet I am so far from desiring that no one should write against me, that it is what I most earnestly wish. For philosophy would never have been in such esteem in Greece itself, if it had not been for the strength which it acquired from the contentions and disputations of the most learned men. And therefore I recommend all men who have abilities to follow my advice to snatch this art also from declining Greece, and to transport it to this city, as our ancestors by their study and industry have imported all their other arts which were worth having. Thus the praise of oratory, raised from a low degree, is arrived at such perfection that it must now decline, and, as is the nature of all things, verge to its dissolution in a very short time. Let philosophy, then, derive its birth in Latin language from this time, and let us lend it our assistance, and bear patiently to be contradicted and refuted. And although those men may dislike such treatment who are bound and devoted to certain predetermined opinions, and are under such obligations to maintain them that they are forced, for the sake of consistency, to adhere to them even though they do not themselves wholly approve of them; we, on the other hand, who pursue only probabilities, and who cannot go beyond that which seems really likely, can confute others without obstinacy, and are prepared to be confuted ourselves without resentment. Besides, if these studies are ever brought home to us, we shall not want even Greek libraries, in which there is an infinite number of books, by reason of the multitude of authors among them; for it is a common practice with many to repeat the same things which have been written by others, which serves no purpose but to stuff their shelves; and this will be our case, too, if many apply themselves to this study.
