Philosophers
It remains only to speak of those who have written on subjects of philosophy. Hitherto we have had but few of this kind. Cicero, as in all other respects, so also in this, was a worthy rival of Plato. Brutus has written some excellent treatises, the merit of which is far superior to that of his orations. He supports admirably well the weight of his matter, and seems to feel what he says. Cornelius Celsus, in the manner of the Skeptics, has written a good many tracts, which are not without elegance and perspicuity. Plancus, among the Stoics, may be read with profit, for the sake of becoming acquainted with the things he discusses. Catius, an Epicurean, has some levity in his way, but in the main is not an unpleasing author.
