XLI. This is the very same which is said by Epicurus and Hieronymus. Now, if those philosophers, whose opinion it is that virtue has no power of itself, and who say that the conduct which we denominate honorable and laudable is really nothing, and is only an empty circumstance set off with an unmeaning sound, can nevertheless maintain that a wise man is always happy, what, think you, may be done by the Socratic and Platonic philosophers? Some of these allow such superiority to the goods of the mind as quite to eclipse what concerns the body and all external circumstances. But others do not admit these to be goods; they make everything depend on the mind: whose disputes Carneades used, as a sort of honorary arbitrator, to determine. For, as what seemed goods to the Peripatetics were allowed to be advantages by the Stoics, and as the Peripatetics allowed no more to riches, good health; and other things of that sort than the Stoics, when these things were considered according to their reality, and not by mere names, his opinion was that there was no ground for disagreeing. Therefore, let the philosophers of other schools see how they can establish this point also. It is very agreeable to me that they make some professions worthy of being uttered by the mouth of a philosopher with regard to a wise man's having always the means of living happily.
XLII. But as we are to depart in the morning, let us remember these five days' discussions; though, indeed, I think I shall commit them to writing: for how can I better employ the leisure which I have, of whatever kind it is, and whatever it be owing to? And I will send these five books also to my friend Brutus, by whom I was not only incited to write on philosophy, but, I may say, provoked. And by so doing it is not easy to say what service I may be of to others. At all events, in my own various and acute afflictions, which surround me on all sides, I cannot find any better comfort for myself.
I. There are many things in philosophy, my dear Brutus, which are not as yet fully explained to us, and particularly (as you very well know) that most obscure and difficult question concerning the Nature of the Gods, so extremely necessary both towards a knowledge of the human mind and the practice of true religion: concerning which the opinions of men are so various, and so different from each other, as to lead strongly to the inference that ignorance[72] is the cause, or origin, of philosophy, and that the Academic philosophers have been prudent in refusing their assent to things uncertain: for what is more unbecoming to a wise man than to judge rashly? or what rashness is so unworthy of the gravity and stability of a philosopher as either to maintain false opinions, or, without the least hesitation, to support and defend what he has not thoroughly examined and does not clearly comprehend?
