[CHAPTER III.]
CATEGORIÆ.
Of the prodigious total of works composed by Aristotle, I have already mentioned that the larger number have perished. But there still remain about forty treatises, of authenticity not open to any reasonable suspicion, which attest the grandeur of his intelligence, in respect of speculative force, positive as well as negative, systematizing patience, comprehensive curiosity as to matters of fact, and diversified applications of detail. In taking account of these treatises, we perceive some in which the order of sequence is determined by assignable reasons; as regards others, no similar grounds of preference appear. The works called 1. De Cœlo; 2. De Generatione et Corruptione; 3. Meteorologica, — are marked out as intended to be studied in immediate succession, and the various Zoological treatises after them. The cluster entitled Parva Naturalia is complementary to the treatise De Animâ. The Physica Auscultatio is referred to in the Metaphysica, and discusses many questions identical or analogous, standing in the relation of prior to a posterior, as the titles indicate; though the title ‘Metaphysica’ is not affixed or recognized by Aristotle himself, and the treatise so called includes much that goes beyond the reach of the Physica. As to the treatises on Logic, Rhetoric, Ethics, Politics, Poetics, Mechanics, &c., we are left to fix for ourselves the most convenient order of study. Of no one among them can we assign the date of composition or publication. There are indeed in the Rhetorica, Politics, and Meteorologica, various allusions which must have been written later than some given events of known date; but these allusions may have been later additions, and cannot be considered as conclusively proving, though they certainly raise a presumption, that the entire work was written subsequently to those events.
The proper order in which the works of Aristotle ought to be studied (like the order proper for studying the Platonic dialogues),[1] was matter of debate from the time of his earliest editors and commentators, in the century immediately preceding the Christian era. Boêthus the Sidonian (Strabo’s contemporary and fellow-student) recommended that the works on natural philosophy and physiology should be perused first; contending that these were the easiest, the most interesting, and, on the whole, the most successful among all the Aristotelian productions. Some Platonists advised that the ethical treatises should be put in the front rank, on the ground of their superior importance for correcting bad habits and character; others assigned the first place to the mathematics, as exhibiting superior firmness in the demonstrations. But Andronikus himself, the earliest known editor of Aristotle’s works, arranged them in a different order, placing the logical treatises at the commencement of his edition. He considered these treatises, taken collectively, to be not so much a part of philosophy as an Organon or instrument, the use of which must be acquired by the reader before he became competent to grasp or comprehend philosophy; as an exposition of method rather than of doctrine.[2] From the time of Andronikus downward, the logical treatises have always stood first among the written or printed works of Aristotle. They have been known under the collective title of the ‘Organon,’ and as such it will be convenient still to regard them.[3]
[1] Scholia, p. 25, b. 37, seq. Br.; p. 321, b. 30; Diogen. L. iii. 62. The order in which the forty-six Aristotelian treatises stand printed in the Berlin edition, and in other preceding editions, corresponds to the tripartite division, set forth by Aristotle himself, of sciences or cognitions generally: 1. Theoretical; θεωρητικαί 2. Practical; πρακτικαί. 3. Constructive or Technical; ποιητικαί.
Patricius, in his Discussiones Peripateticæ, published in 1581 (tom. i. lib. xiii. p. 173), proclaims himself to be the first author who will undertake to give an account of Aristotle’s philosophy from Aristotle himself (instead of taking it, as others before him had done, from the Aristotelian expositors, Andronikus, Alexander, Porphyry, or Averroes); likewise, to be the first author who will consult all the works of Aristotle, instead of confining himself, as his predecessors had done, to a select few of the works. Patricius then proceeds to enumerate those works upon which alone the professors “in Italicis scholis� lectured, and to which the attention of all readers was restricted. 1. The Predicabilia, or Eisagoge of Porphyry. 2. The Categoriæ. 3. The De Interpretatione. 4. The Analytica Priora; but only the four first chapters of the first book. 5. The Analytica Posteriora; but only a few chapters of the first book; nothing of the second. 6. The Physica; books first and second; then parts of the third and fourth; lastly, the eighth book. 7. The De Cœlo; books first and second. 8. The De Generatione et Corruptione; books first and second. 9. The De Animâ; all the three books. 10. The Metaphysica; books Alpha major, Alpha minor, third, sixth, and eleventh. “Idque, quadriennio integro, quadruplicis ordinis Philosophi perlegunt auditoribus. De reliquis omnibus tot libris, mirum silentium.�
Patricius expressly remarks that neither the Topica nor the De Sophisticis Elenchis was touched in this full course of four years. But he does not remark — what to a modern reader will seem more surprising — that neither the Ethica, nor the Politica, nor the Rhetorica, is included in the course.
[2] Aristot. Topica, i. p. 104, b. 1, with the Scholia of Alexander, p. 259, a. 48 Br.; Scholia ad Analyt. Prior. p. 140, a. 47, p. 141, a. 25; also Schol. ad Categor. p. 36, a., p. 40, a., 8. This conception of the Organon is not explicitly announced by Aristotle, but seems quite in harmony with his views. The contemptuous terms in which Prantl speaks of it (Gesch. der Logik, i. 136), as a silly innovation of the Stoics, are unwarranted.
Aristotle (Metaph. E. i. p. 1025, b. 26) classifies the sciences as θεωρητικαί, πρακτικαί, ποιητικαί; next he subdivides the first of the three into φυσική, μαθηματική, πρώτη φιλοσοφία. Brentano, after remarking that no place in this distribution is expressly provided for Logic, explains the omission as follows: “Diese auffallende Erscheinung erklärt sich daraus, dass diese [the three above-named theoretical sciences] allein das reelle Sein betrachten, und nach den drei Graden der Abstraktion in ihrer Betrachtungsweise verschieden, geschieden werden; während die Logik das bloss rationelle Sein, das ὃν ὡς ἀληθές, behandelt.â€� (Ueber die Bedeutung des Seienden nach Aristoteles, p. 39.) — Investigations περὶ τῆς ἀληθείας, ὃν τρόπον δεῖ ἀποδέχεσθαι are considered by Aristotle as belonging to τὰ Ἀναλυκτικά; enquiries into method in the first instance, and into doctrine chiefly with a view to method (Metaphys. Γ. p. 1005, b. 2. In Metaphys. Γ. 1005, b. 7, he declares that these enquiries into method, or analysis of the principia of syllogistic reasoning, belong to the Philosophia Prima (compare Metaphys. Z. 12, p. 1037, b. 8). Schwegler in his Commentary (p. 161) remarks that this is one of the few passages in which Aristotle indicates the relation in which Logic stands to Metaphysics, or First Philosophy. The question has been started among his Ἀπορίαι, Metaph. B. 2, p. 999, b. 30.
