 all-important consequence of this first departure from Platonism was that Aristotle became and remained primarily a metaphysician. After Plato’s death, coming to his third period he made a further departure from Platonism in his didactic works on politics and rhetoric, written in connexion with Alexander and Theodectes. Those on politics (Fragm. 646–648) were designed to instruct Alexander on monarchy and on colonization; and in them Aristotle agreed with Plato in assigning a moral object to the state, but departed from him by saying that a king need not be a philosopher, as Plato had said in the Republic, but does need to listen to philosophers. Still more marked was his departure from Plato as regards rhetoric. Plato in the Gorgias, (501 ) had contended that rhetoric is not an art but an empirical practice ( ); Aristotle in the Gryllus (Fragm. 68-69), written in his second period, took according to Quintilian a similar view. But in his third period, in the Theodectea (Fragm. 125 seq.), rhetoric is treated as an art, and is laid out somewhat in the manner of his later Art of Rhetoric; while he also showed his interest in the subject by writing a history of other arts of rhetoric called  (Fragm. 136 seq.). Further, in treating rhetoric as an art in the Theodectea he was forced into a conclusion, which carried him far beyond Plato’s rigid notions of proof and of passion: he concluded that it is the work of an orator to use persuasion, and to arouse the passions ( ), e.g. anger and pity (ib. 133-134). Nor could he treat poetry as he is said to have done without the same result.

On the whole then, in his early dialectical and didactic writings, of which mere fragments remain, Aristotle had already diverged from Plato, and first of all in metaphysics. During his master’s life, in the second period of his own life, he protested against the Platonic hypothesis of forms, formal numbers and the one as the good, and tended to separate metaphysics from dialectic by beginning to pass from dialogues to didactic works. After his master’s death, in the third period of his own life, and during his connexion with Alexander, but before the final construction of his philosophy into a system, he was tending to write more and more in the didactic style; to separate from dialectic, not only metaphysics, but also politics, rhetoric and poetry; to admit by the side of philosophy the arts of persuasive language; to think it part of their legitimate work to rouse the passions; and in all these ways to depart from the ascetic rigidity of the philosophy of Plato, so as to prepare for the tolerant spirit of his own, and especially for his ethical doctrine that virtue consists not in suppressing but in moderating almost all human passions. In both periods, too, as we shall find in the sequel, he was already occupied in composing some of the extant writings which were afterwards to form parts of his final philosophical system. But as yet he had given no sign of system, and—what is surprising—no trace of logic. Aristotle was primarily a metaphysician against Plato; a metaphysician before he was a logician; a metaphysician who made what he called primary philosophy ( ) the starting-point of his philosophical development, and ultimately of his philosophical system.

The system which was taught by Aristotle at Athens in the fourth period of his life, and which is now known as the Aristotelian philosophy, is contained not in fragments but in extant books. It will be best then to give at once a list of these extant works, following the traditional order in which they have long been arranged, and marking with a dagger (†) those which are now usually considered not to be genuine, though not always with sufficient reason.
