[34] What Strabo asserts about the Peripatetic Scholarchs succeeding Theophrastus (viz., μηδὲν ἔχειν φιλοσοφεῖν πραγματικῶς, ἀλλὰ θέσεις ληκυθίζειν: that they could not handle philosophy in a businesslike way — with those high generalities and that subtle analysis which was supposed to belong to philosophy — but gave smooth and ornate discourses on set problems or theses) is fully borne out by what we read in Cicero about these same Peripatetics. The Stoics (immediate successors and rivals) accused their Peripatetic contemporaries even of being ignorant of Dialectic: which their founder, Aristotle, in his works that we now possess, had been the first to raise into something like a science. Cicero says (De Finibus, iii. 12, 41): “His igitur ita positis (inquit Cato) sequitur magna contentio: quam tractatam à Peripateticis mollius (est enim eorum consuetudo dicendi non satis acuta, propter ignorationem Dialecticæ), Carneades tuus, egregiâ quâdam exercitatione in dialecticis summâque eloquentiâ, rem in summum discrimen adduxit.â€� Also Cicero, in Tuscul. Disput. iv. 5. 9: “Quia Chrysippus et Stoici, quum de animi perturbationibus disputant, magnam partem in iis partiendis et definiendis occupati sunt, illa eorum perexigua oratio est, quâ medeantur animis nec eos turbulentos esse patiantur. Peripatetici autem ad placandos animos multa afferunt, spinas partiendi et definiendi prætermittunt.â€� This last sentence is almost an exact equivalent of the words of Strabo: μηδὲν ἔχειν φιλοσοφεῖν πραγματικῶς, ἀλλὰ θέσεις ληκυθίζειν. Aristotle himself, in the works which we possess, might pass as father of the Stoics rather than of the Peripatetics; for he abounds in classification and subdivision (spinas partiendi et dividendi), and is even derided on this very ground by opponents (see Atticus ap. Euseb. Præp. Ev. xv. 4); but he has nothing of the polished amplification ascribed to the later Peripatetics by Strabo and Cicero. Compare, about the Peripatetics from Lykon to Kritolaus, Cicero, De Finibus, v. 5: “Lyco, oratione locuples, rebus ipsis jejunior.â€� Plutarch (Sylla, c. xxvi.) calls these later Peripatetics χαριέντες καὶ φιλόλογοι, &c.
I shall assume this variety, both of subject and of handling, as a feature to be admitted and allowed for in Aristotle, when I come to discuss the objections of some critics against the authenticity of certain treatises among the forty-six which now pass under his name. But in canvassing the Aristotelian Canon I am unable to take the same ground as I took in my former work, when reviewing the Platonic Canon. In regard to Plato, I pointed out a strong antecedent presumption in favour of the Canon of Thrasyllus — a canon derived originally from the Alexandrine librarians, and sustained by the unanimous adhesion of antiquity. In regard to Aristotle, there are no similar grounds of presumption to stand upon. We have good reason for believing that the works both of Plato and Aristotle — if not all the works, at least many of them, and those the most generally interesting — were copied and transmitted early to the Alexandrine library. Now our Plato represents that which was possessed and accredited as Platonic by the Byzantine Aristophanes and the other Alexandrine librarians; but our Aristotle does not, in my judgment, represent what these librarians possessed and accredited as Aristotelian. That which they thus accredited stands recorded in the Catalogue given by Diogenes, probably the work of Hermippus, as I have already stated; while our Aristotle is traceable to the collection at Athens, including that of Apellikon, with that which he bought from the heirs of Neleus, and to the sifting, correction, and classification, applied thereto by able critics of the first century B.C. and subsequently; among whom Andronikus is best known. We may easily believe that the library of Apellikon contained various compositions of Aristotle, which had never been copied for the Alexandrine library — perhaps never prepared for publication at all, so that the task of arranging detached sections or morsels into a whole, with one separate title, still remained to be performed. This was most likely to be the case with abstruser speculations, like the component books of the Metaphysica, which Theophrastus may not have been forward to tender, and which the library might not be very eager to acquire, having already near four hundred other volumes by the same author. These reserved works would therefore remain in the library of Theophrastus, not copied and circulated (or at least circulated only to a few private philosophical brethren, such as Eudêmus), so that they never became fully published until the days of Apellikon.[35]
[35] The two Peripatetic Scholarchs at Athens, Straton and Lykon, who succeeded (after the death of Theophrastus and the transfer of his library to Skêpsis) in the conduct of the school, left at their decease collections of books, of which each disposes by his will (Diogen. L. v. 62; v. 73). The library of Apellikon, when sent by Sylla to Rome, contained probably many other Aristotelian MSS., besides those purchased from Skêpsis.
Michelet, in his Commentary on the Nikomachean Ethica, advances a theory somewhat analogous but bolder, respecting the relation between the Catalogue given by Diogenes, and the works contained in our Aristotle. Comm. p. 2. “Id solum addam, hoc Aristotelis opus (the Nikomachean Ethica), ut reliqua omnia, ex brevioribus commentationibus consarcinatum fuisse, quæ quidem vivo Aristotele in lucem prodierint, cum unaquæque disciplina, e quâ excerpta fuerint in admirabilem illum quem habemus ordinem jam ab ipso Aristotele sive quodam ejus discipulo redacta, in libris Aristotelis manu scriptis latitaverit, qui hereditate ad Nelei prolem, ut notum est, transmissi, in cellâ illâ subterraneâ Scepsiâ absconditi fuerunt, donec Apellicon Teius et Rhodius Andronicus eos ediderint. Leguntur autem commentationum illarum de Moribus tituli in elencho librorum Aristotelis apud Diogenem (v. 22-26): περὶ ἀρετῶν (Lib. ii., iii. c. 6-fin. iv. nostrorum Ethicorum); περὶ ἑκουσίου (Lib. iii. c. 1-5); &c. Plerumque enim non integra volumina, sed singulos libros vel singula volumina diversarum disciplinarum, Diogenes in elencho suo enumeravit.â€�
In his other work (Essai sur la Métaphysique d’Aristote, pp. 202, 205, 225) Michelet has carried this theory still farther, and has endeavoured to identify separate fragments of the Aristotelian works now extant, with various titles in the Catalogue given by Diogenes. The identification is not convincing.
But though the edition published by Andronikus would thus contain many genuine works of Aristotle not previously known or edited, we cannot be sure that it would not also include some which were spurious. Reflect what the library of Apellikon, transported to Rome by Sylla, really was. There was in it the entire library of Theophrastus; probably, also, that of Neleus, who must have had some books of his own, besides what he inherited from Theophrastus. It included all the numerous manuscript works composed by Aristotle and Theophrastus, and many other manuscript works purchased or acquired by them, but composed by others — the whole in very bad order and condition; and, moreover, the books which Apellikon possessed before, doubtless as many Aristotelian books as he could purchase. To distinguish, among this heterogeneous mass of manuscripts, which of them were the manuscripts composed by Aristotle; to separate these from the writings of Theophrastus, Eudêmus, or other authors, who composed various works of their own upon the same subjects and with the same titles as those of Aristotle — required extreme critical discernment and caution; the rather, since there was no living companion of Aristotle or Theophrastus to guide or advise, more than a century and a half having elapsed since the death of Theophrastus, and two centuries since that of Aristotle. Such were the difficulties amidst which Apellikon, Tyrannion, and Andronikus had to decide, when they singled out the manuscripts of Aristotle to be published. I will not say that they decided wrongly; yet neither can I contend (as I argued in the case of the Platonic dialogues) that the presumption is very powerful in favour of that Canon which their decision made legal. The case is much more open to argument, if any grounds against the decision can be urged.
Andronikus put in, arranged, and published the treatises of Aristotle (or those which he regarded as composed by Aristotle) included in the library conveyed by Sylla to Rome. I have already observed, that among these treatises there were some, of which copies existed in the Alexandrine library (as represented by the Catalogue of Diogenes), but a still greater number which cannot be identified with the titles remaining of works there preserved. As to the works common to both libraries, we must remember that Andronikus introduced a classification of his own, analogous to the Enneads applied by Porphyry to the works of Plotinus, and to the Tetralogies adopted by Thrasyllus in regard to the Dialogues of Plato; so that even these works might not be distributed in the same partitions under each of the two arrangements. And this is what we actually see when we compare the Catalogue of Diogenes with our Aristotle. Rhetoric, Ethics, Physics, Problems, &c., appear in both as titles or subjects, but distributed into a different number of books or sections in one and in the other; perhaps, indeed, the compositions are not always the same.
Before I proceed to deal with the preserved works of Aristotle — those by which alone he is known to us, and was known to mediæval readers, I shall say a few words respecting the import of a distinction which has been much canvassed, conveyed in the word exoteric and its opposite. This term, used on various occasions by Aristotle himself, has been also employed by many ancient critics, from Cicero downwards; while by mediæval and modern critics, it has not merely been employed, but also analysed and elucidated. According to Cicero (the earliest writer subsequent to Aristotle in whom we find the term), it designates one among two classes of works composed by Aristotle: exoteric works were those composed in a popular style and intended for a large, indiscriminate circle of readers: being contrasted with other works of elaborated philosophical reasoning, which were not prepared for the public taste, but left in the condition of memorials for the instruction of a more select class of studious men. Two points are to be observed respecting Cicero’s declaration. First, he applies it to the writings not of Aristotle exclusively, but also to those of Theophrastus, and even of succeeding Peripatetics; secondly, he applies it directly to such of their writings only as related to the discussion of the Summum Bonum.[36] Furthermore, Cicero describes the works which Aristotle called exoteric, as having proems or introductory prefaces.[37]
[36] Cicero, De Finibus, v. 5, 12. “De summo autem bono, quia duo genera librorum sunt, unum populariter scriptum, quod ἐξωτερικὸν appellabant, alterum limatius, quod in commentariis reliquerunt, non semper idem dicere videntur: nec in summâ tamen ipsâ aut varietas est ulla, apud hos quidem quos nominavi, aut inter ipsos dissensio.â€�
The word limatius here cannot allude to high polish and ornament of style (nitor orationis), but must be equivalent to ἀκριβέστερον, doctius, subtilius, &c. (as Buhle and others have already remarked, Buhle, De Libris Aristot. Exoter. et Acroam. p. 115; Madvig, ad Cicero de Finib. v. 12; Heitz, p. 134), applied to profound reasoning, with distinctions of unusual precision, which it required a careful preparatory training to apprehend. This employment of the word limatius appears to me singular, but it cannot mean anything else here. The commentarii are the general heads — plain unadorned statements of facts or reasoning — which the orator or historian is to employ his genius in setting forth and decorating, so that it may be heard or read with pleasure and admiration by a general audience. Cicero, in that remarkable letter wherein he entreats Lucceius to narrate his (Cicero’s) consulship in an historical work, undertakes to compose “commentarios rerum omniumâ€� as materials for the use of Lucceius (Ep. ad Famil. v. 12. 10). His expression, “in commentariis reliquerunt,â€� shows that he considered the exoteric books to have been prepared by working up some naked preliminary materials into an ornate and interesting form.
