And these subjects were very frequently and very copiously discussed by us at other times, and once also in the villa of Hortensius, which is at Bauli, when Catulus, and Lucullus, and I myself had arrived there the day after we had been staying with Catulus. And we had come thither rather early [pg 027] in the day, because we had intended, if the wind was fair, to set sail, Lucullus for his villa near Naples, and I myself towards mine, in the district of Pompeii. When, therefore, we had had a short conversation on the terrace, we sat down where we were.
IV. Then Catulus said,—Although what we were inquiring into yesterday was almost wholly explained in such a manner that nearly the whole question appears to have been discussed, still I long to hear what you promised to tell us, Lucullus, as being what you had learnt from Antiochus. I, indeed, said Hortensius, did more than I intended, for the whole matter ought to have been left untouched for Lucullus, and indeed, perhaps it was: for I only said such things as occurred to me at the moment; but I hope to hear something more recondite from Lucullus.
Lucullus rejoined, I am not much troubled, Hortensius, at your expectation, although there is nothing so unfavourable for those who wish to give pleasure; but still, as I am not very anxious about how far I can prove to your satisfaction the arguments which I advance, I am the less disturbed. For the arguments which I am going to repeat are not my own, nor such that, if they are incorrect, I should not prefer being defeated to gaining the victory; but, in truth, as the case stands at present, although the doctrines of my school were somewhat shaken in yesterday's discussion, still they do seem to me to be wholly true. I will therefore argue as Antiochus used to argue; for the subject is one with which I am well acquainted. For I used to listen to his lectures with a mind quite unengaged, and with great pleasure, and, moreover, he frequently discussed the same subject over again; so that you have some grounds for expecting more from me than you had from Hortensius a little while ago. When he had begun in this manner we prepared to listen with great attention.
And he spoke thus:—When I was at Alexandria, as proquæstor, Antiochus was with me, and before my arrival, Heraclitus, of Tyre, a friend of Antiochus, had already settled in Alexandria, a man who had been for many years a pupil of Clitomachus and of Philo, and who had a great and deserved reputation in that school, which having been almost utterly discarded, is now coming again into fashion; and I used often to hear Antiochus arguing with him; but they both conducted [pg 028] their discussions with great gentleness. And just at that time those two books of Philo which were yesterday mentioned by Catulus had been brought to Alexandria, and had for the first time come under the notice of Antiochus; and he, though naturally a man of the mildest disposition, (nor indeed was it possible for any one to be more peaceable than he was,) was nevertheless a little provoked. I was surprised, for I had never seen him so before: but he, appealing to the recollection of Heraclitus, began to inquire of him whether he had seen those works of Philo, or whether he had heard the doctrines contained in them, either from Philo or from any one else of the Academic school? And he said that he had not; however, he recognised the style of Philo, nor, indeed, could there be any doubt about it; for some friends of mine, men of great learning, Publius and Caius Setilius, and Tetrilius Rogus were present, who said that they heard Philo advance such operations at Rome; and who said that they had written out those two books from his dictation. Then Antiochus repeated what Catulus mentioned yesterday, as having been said to Philo by his father, and many other things besides; nor did he forbear even to publish a book against his own master, which is called “Sosus.”
I therefore, then, as I was much interested in hearing Heraclitus arguing against Antiochus, and Antiochus against the Academicians, paid great attention to Antiochus, in order to learn the whole matter from him. Accordingly, for many days, collecting together Heraclitus and several learned men, and among them Aristus, the brother of Antiochus, and also Ariston and Dion, men whom he considered only second to his brother in genius, we devoted a great deal of time to that single discussion.
But we must pass over that part of it which was bestowed on refuting the doctrines of Philo; for he is a less formidable adversary, who altogether denies that the Academicians advance those arguments which were maintained yesterday. For although he is quite wrong as to the fact, still he is a less invincible adversary. Let us speak of Arcesilas and Carneades.
V. And having said this, he began again:—You appear to me, in the first place, (and he addressed me by name,) when you speak of the old natural philosophers, to do the same [pg 029] thing that seditious citizens are in the habit of doing when they bring forward some illustrious men of the ancients, who they say were friends of the people, in the hope of being themselves considered like them. They go back to Publius Valerius, who was consul the first year after the expulsion of the kings. They enumerate all the other men who have passed laws for the advantage of the people concerning appeals when they were consuls; and then they come down to these better known men, Caius Flaminius, who, as tribune of the people, passed an Agrarian law some years before the second Punic war, against the will of the senate, and who was afterwards twice elected consul; to Lucius Cassius and Quintus Pompeius; they are also in the habit of classing Publius Africanus in the same list; and they assert that those two brothers of infinite wisdom and exceeding glory, Publius Crassus and Publius Scævola, were the advisers of Tiberius Gracchus, in the matter of the laws which he proposed; the one, indeed, as we see, openly; the other, as we suspect, in a more concealed manner. They add also Caius Marius; and with respect to him they speak truly enough: then, having recounted the names of so many illustrious men, they say that they are acting up to their principles.
In like manner, you, when you are seeking to overturn a well-established system of philosophy, in the same way as those men endeavoured to overturn the republic, bring forward the names of Empedocles, Anaxagoras, Democritus, Parmenides, Xenophanes, and even Plato and Socrates. But Saturninus, (that I may name my own enemy rather than any one else,) had nothing in him resembling those ancient men; nor are the ungrounded accusations of Arcesilas to be compared to the modesty of Democritus. And yet those natural philosophers, though very seldom, when they have any very great difficulty, make loud and violent outcries, as if under the influence of some great excitement, Empedocles, indeed, does so to such a degree, that he appears to me at times to be mad, crying out that all things are hidden, that we feel nothing, see nothing, and cannot find out the true character of anything whatever. But for the most part all those men appear to me to affirm some things rather too positively, and to profess that they know more than they really do know. But if they then hesitated while discussing new subjects, like children lately born, are we for that reason [pg 030] to think that nothing has been explained in so many ages by the greatest genius and the most untiring industry? May we not say that, after the establishment of some wise and important schools of philosophy, then, as Tiberius Gracchus arose in an excellent constitution, for the purpose of throwing everything into confusion, so Arcesilas rose up to overturn the established philosophy, and to shelter himself under the authority of those men who asserted that nothing could be known or perceived; in which number we ought not to include Plato or Socrates; the one because he left behind him a most perfect school, namely, the Peripatetics and Academics, differing in name, but agreeing in all substantial matters: and from whom the Stoics themselves differ in words rather than in opinions. But Socrates, who always disparaged himself in arguing, attributed more knowledge to those whom he wished to refute. So, as he was speaking differently from what he really thought, he was fond of using that kind of dissimulation which the Greeks call εἰρωνεία; which Fannius says Africanus also was in the habit of indulging in, and that that ought not be considered a bad habit in him, as it was a favourite practice of Socrates.
VI. But, however, we will allow, if you like, that all those things were unknown to the ancients:—was nothing effected then, by their being thoroughly investigated, after that Arcesilas, disparaging Zeno, (for that is supposed to have been his object,) as discovering nothing new, but only correcting previous changes of names, while seeking to upset his definitions, had attempted to envelop the clearest possible matters in darkness? And his system, which was at first not at all approved of, although it was illustrated both by acute genius and by an admirable wittiness of language, was in the next generation adopted by no one but Lacydes; but subsequently it was perfected by Carneades, who was the fourth in succession from Arcesilas; for he was the pupil of Hegesinus, who had been the pupil of Evander, the disciple of Lacydes, and Lacydes himself had been the pupil of Arcesilas; but Carneades maintained it for a long time, for he lived ninety years; and those who had been his pupils had a very high reputation, of whom Clitomachus displayed the most industry, as the number of books which he composed testifies; nor was there less brilliancy of genius in him than there was of eloquence in Charmadas, or of sweetness in Melanthius of Rhodes. [pg 031] But Metrodorus of Stratonice was thought to be the one who had the most thorough understanding of Carneades. And your friend Philo attended the lectures of Clitomachus for many years; but as long as Philo was alive the Academy was never in want of a head.
But the business that we now propose to ourselves, of arguing against the Academicians, appears to some philosophers, and those, too, men of no ordinary calibre, to be a thing that ought not to be done at all; and they think that there is no sense at all in, and no method of disputing with men who approve of nothing; and they blame Antipater, the Stoic, who was very fond of doing so, and say that there is no need of laying down exact definitions of what knowledge is, or perception, or, if we want to render word for word, comprehension, which they call κατάληψις; and they say that those who wish to persuade men that there is anything which can be comprehended and perceived, are acting ignorantly; because there is nothing clearer than ἐνάργεια, as the Greeks call it, and which we may call perspicuity, or evidentness if you like,—coining words, if you will permit us to do so, that this fellow (meaning me) may not think that he is the only person to whom such liberties are permitted. Still they thought that no discourse could be found which should be more intelligible than evidentness itself; and they thought that there was no need of defining things which were so clear.
