Piso replied—Although, while our friend here (meaning me) is present, this matter will perhaps not be quite so easy; yet I will endeavour to call you back from this NewAcademy to that ancient one, in which (as you used to hear Antiochus say) those men are not alone reckoned who are called Academics,—Speusippus, Xenocrates, Polemo, Crantor, and the rest; but the old Peripatetics also, the chief of whom was Aristotle, whom, next to Plato, I think I may fairly call the prince of philosophers. Turn yourself, therefore, I entreat you, to those men; for from their writings and systems all liberal learning, all history, all elegance of language, may be derived; and also, so great is the variety of arts of which they were masters, that no one can come properly armed for any business of importance and credit without being tolerably versed in their writings. It is owing to them that men have turned out orators, generals, and statesmen; and, to descend to less important matters, it is from this Academy, as from a regular magazine of all the arts, that mathematicians, poets, musicians, aye, and physicians too, have proceeded.
I replied—You know well, O Piso, that my opinion is the same: but still the mention of it by you was very seasonable; for my relation Cicero is anxious to hear what was the doctrine of that Old Academy which you have been speaking of, and of the Peripatetics, about the chief good; and we think that you can very easily explain it to us, because you entertained Staseas the Neapolitan in your house for many years, and because, too, we are aware that you have been many months at Athens, investigating these very things, as a pupil of Antiochus. And he said, with a laugh, Come, come,—for you have very cleverly drawn me in to begin the discussion,—let us explain it to the young man if we can; for this solitude gives us the opportunity: but, even if a god had told me so, I would never have believed that I should be disputing in the Academy, like a philosopher. However, I hope I shall not annoy the rest of you while complying with his request. Annoy me, said I, who asked you? Quintus and Pomponius also said that they entertained the same wish; so he began. And I beg of you, Brutus, to consider whether what he said appears to you to sufficiently embrace the doctrines of Antiochus, which I know you, who were a constant attendant on the lectures of his brother Aristus, approve of highly. Thus he spoke:—
