IX. This was the first philosophy handed down to them by Plato. And if you like I will explain to you those discussions which have originated in it. Indeed, said I, we shall be glad if you will; and I can answer for Atticus as well as for myself. You are quite right, said he; for the doctrine both of the Peripatetics and of the old Academy is most admirably explained.
Aristotle, then, was the first to undermine the doctrine of [pg 017] species, which I have just now mentioned, and which Plato had embraced in a wonderful manner; so that he even affirmed that there was something divine in it. But Theophrastus, a man of very delightful eloquence, and of such purity of morals that his probity and integrity were notorious to all men, broke down more vigorously still the authority of the old school; for he stripped virtue of its beauty, and made it powerless, by denying that to live happily depended solely on it. For Strato, his pupil, although a man of brilliant abilities, must still be excluded entirely from that school; for, having deserted that most indispensable part of philosophy which is placed in virtue and morals, and having devoted himself wholly to the investigation of nature, he by that very conduct departs as widely as possible from his companions. But Speusippus and Xenocrates, who were the earliest supporters of the system and authority of Plato,—and, after them, Polemo and Crates, and at the same time Crantor,—being all collected together in the Academy, diligently maintained those doctrines which they had received from their predecessors. Zeno and Arcesilas had been diligent attenders on Polemo; but Zeno, who preceded Arcesilas in point of time, and argued with more subtilty, and was a man of the greatest acuteness, attempted to correct the system of that school. And, if you like, I will explain to you the way in which he set about that correction, as Antiochus used to explain it. Indeed, said I, I shall be very glad to hear you do so; and you see that Pomponius intimates the same wish.
X. Zeno, then, was not at all a man like Theophrastus, to cut through the sinews of virtue; but, on the other hand, he was one who placed everything which could have any effect in producing a happy life in virtue alone, and who reckoned nothing else a good at all, and who called that honourable which was single in its nature, and the sole and only good. But as for all other things, although they were neither good nor bad, he divided them, calling some according to, and others contrary to nature. There were others which he looked upon as placed between these two classes, and which he called intermediate. Those which were according to nature, he taught his disciples, deserved to be taken, and to be considered worthy of a certain esteem. To those which were contrary to nature, he assigned a contrary character; and those of the [pg 018] intermediate class he left as neutrals, and attributed to them no importance whatever. But of those which he said ought to be taken, he considered some worthy of a higher estimation and others of a less. Those which were worthy of a higher esteem, he called preferred; those which were only worthy of a lower degree, he called rejected. And as he had altered all these things, not so much in fact as in name, so too he defined some actions as intermediate, lying between good deeds and sins, between duty and a violation of duty;—classing things done rightly as good actions, and things done wrongly (that is to say, sins) as bad actions. And several duties, whether discharged or neglected, he considered of an intermediate character, as I have already said. And whereas his predecessors had not placed every virtue in reason, but had said that some virtues were perfected by nature, or by habit, he placed them all in reason; and while they thought that those kinds of virtues which I have mentioned above could be separated, he asserted that that could not be done in any manner, and affirmed that not only the practice of virtue (which was the doctrine of his predecessors), but the very disposition to it, was intrinsically beautiful; and that virtue could not possibly be present to any one without his continually practising it.
And while they did not entirely remove all perturbation of mind from man, (for they admitted that man did by nature grieve, and desire, and fear, and become elated by joy,) but only contracted it, and reduced it to narrow bounds; he maintained that the wise man was wholly free from all these diseases as they might be called. And as the ancients said that those perturbations were natural, and devoid of reason, and placed desire in one part of the mind and reason in another, he did not agree with them either; for he thought that all perturbations were voluntary, and were admitted by the judgment of the opinion, and that a certain unrestrained intemperance was the mother of all of them. And this is nearly what he laid down about morals.
XI. But about natures he held these opinions. In the first place, he did not connect this fifth nature, out of which his predecessors thought that sense and intellect were produced, with those four principles of things. For he laid it down that fire is that nature which produces everything, and intellect, and sense. But he differed from them again, inasmuch [pg 019] as he thought it absolutely impossible for anything to be produced from that nature which was destitute of body; which was the character attributed by Xenocrates and his predecessors to the mind, and he would not allow that that which produced anything, or which was produced by anything, could possibly be anything except body.
But he made a great many alterations in that third part of his philosophy, in which, first of all, he said some new things of the senses themselves: which he considered to be united by some impulse as it were, acting upon them from without, which he called φαντασία, and which we may term perception. And let us recollect this word, for we shall have frequent occasion to employ it in the remainder of our discourse; but to these things which are perceived, and as it were accepted by the senses, he adds the assent of the mind, which he considers to be placed in ourselves and voluntary. He did not give credit to everything which is perceived, but only to those which contain some especial character of those things which are seen; but he pronounced what was seen, when it was discerned on account of its own power, comprehensible—will you allow me this word? Certainly, said Atticus, for how else are you to express καταληπτός? But after it had been received and approved, then he called it comprehension, resembling those things which are taken up (prehenduntur) in the hand; from which verb also he derived this noun, though no one else had ever used this verb with reference to such matters; and he also used many new words, for he was speaking of new things. But that which was comprehended by sense he called felt (sensum,) and if it was so comprehended that it could not be eradicated by reason, he called it knowledge; otherwise he called it ignorance: from which also was engendered opinion, which was weak, and compatible with what was false or unknown. But between knowledge and ignorance he placed that comprehension which I have spoken of, and reckoned it neither among what was right or what was wrong, but said that it alone deserved to be trusted.
And from this he attributed credit also to the senses, because, as I have said above, comprehension made by the senses appeared to him to be true and trustworthy. Not because it comprehended all that existed in a thing, but because it left out nothing which could affect it, and because [pg 020] nature had given it to us to be as it were a rule of knowledge, and a principle from which subsequently all notions of things might be impressed on our minds, from which not only principles, but some broader paths to the discovery of reason are found out. But error, and rashness, and ignorance, and opinion, and suspicion, and in a word everything which was inconsistent with a firm and consistent assent, he discarded from virtue and wisdom. And it is in these things that nearly all the disagreement between Zeno and his predecessors, and all his alteration of their system consists.
XII. And when he had spoken thus—You have, said I, O Varro, explained the principles both of the Old Academy and of the Stoics with brevity, but also with great clearness. But I think it to be true, as Antiochus, a great friend of mine, used to assert, that it is to be considered rather as a corrected edition of the Old Academy, than as any new sect. Then Varro replied—It is your part now, who revolt from the principles of the ancients, and who approve of the innovations which have been made by Arcesilas, to explain what that division of the two schools which he made was, and why he made it; so that we may see whether that revolt of his was justifiable. Then I replied—Arcesilas, as we understand, directed all his attacks against Zeno, not out of obstinacy or any desire of gaining the victory, as it appears to me, but by reason of the obscurity of those things which had brought Socrates to the confession of ignorance, and even before Socrates, Democritus, Anaxagoras, Empedocles, and nearly all the ancients; who asserted that nothing could be ascertained, or perceived, or known: that the senses of man were narrow, his mind feeble, the course of his life short, and that truth, as Democritus said, was sunk in the deep; that everything depended on opinions and established customs; that nothing was left to truth. They said in short, that everything was enveloped in darkness; therefore Arcesilas asserted that there was nothing which could be known, not even that very piece of knowledge which Socrates had left himself. Thus he thought that everything lay hid in secret, and that there was nothing which could be discerned or understood; for which reasons it was not right for any one to profess or affirm anything, or sanction anything by his assent, but men ought always to restrain their rashness and to keep it in check [pg 021] so as to guard it against every fall. For rashness would be very remarkable when anything unknown or false was approved of; and nothing could be more discreditable than for a man's assent and approbation to precede his knowledge and perception of a fact. And he used to act consistently with these principles, so as to pass most of his days in arguing against every one's opinion, in order that when equally important reasons were found for both sides of the same question, the judgment might more naturally be suspended, and prevented from giving assent to either.
This they call the New Academy, which however appears to me to be the old one, if, at least, we reckon Plato as one of that Old Academy. For in his books nothing is affirmed positively, and many arguments are allowed on both sides of a question; everything is investigated, and nothing positive affirmed. Still let the school whose principles I have explained, be called the Old Academy, and this other the New; which, having continued to the time of Carneades, who was the fourth in succession after Arcesilas, continued in the same principles and system as Arcesilas. But Carneades, being a man ignorant of no part of philosophy, and, as I have learnt from those who had been his pupils, and particularly from Zeno the Epicurean, who, though he greatly differed from him in opinion, still admired him above all other men, was also a person of incredible abilities...
