THREE:But numerous as are the obligations, whether real or imaginary, of the Alexandrian to the Athenian teacher, they range over a comparatively limited field. What most interests a modern student in Platonismits critical preparation, its conversational dialectic, its personal episodes, its moral enthusiasm, its political superstructurehad apparently no interest for Plotinus as a writer. He goes straight to the metaphysical core of the system, and occupies himself with re-thinking it in its minutest details. Now this was just the part which had either not been286 discussed at all, or had been very insufficiently discussed by his predecessors. It would seem that the revival of Platonic studies had followed an order somewhat similar to the order in which Platos own ideas were evolved. The scepticism of the Apologia had been taken up and worked out to its last consequences by the New Academy. The theory of intuitive knowledge, the ethical antithesis between reason and passion, and the doctrine of immortality under its more popular form, had been resumed by the Greek and Roman Eclectics. Plutarch busied himself with the erotic philosophy of the Phaedrus and the Symposium, as also did his successor, Maximus Tyrius. In addition to this, he and the other Platonists of the second century paid great attention to the theology adumbrated in those dialogues, and in the earlier books of the Republic. But meanwhile Neo-Pythagoreanism had intervened to break the normal line of development, and, under its influence, Plutarch passed at once to the mathematical puzzles of the Timaeus. With Plato himself the next step had been to found a state for the application of his new principles; and such was the logic of his system, that the whole stress of adverse circumstances could not prevent the realisation of a similar scheme from being mooted in the third century; while, as we have seen, something more remotely analogous to it was at that very time being carried out by the Christian Church. Platos own disappointed hopes had found relief in the profoundest metaphysical speculations; and now the time has come when his labours in this direction were to engage the attention hitherto absorbed by the more popular or literary aspects of his teaching.In the theory of reasoning the simple proposition is taken as a starting-point; but instead of deducing the syllogism379 from the synthesis of two premises, Aristotle reaches the premises through the conclusion. He tells us, indeed, that reasoning is a way of discovering from what we know, something that we did not know before. With him, however, it is really a process not of discovery but of proof. He starts with the conclusion, analyses it into predicate and subject or major and minor, and then, by a further analysis, introduces a middle term connecting the two. Thus, we begin with the proposition, Caius is mortal, and prove it by interpolating the notion humanity between its two extremes. From this point of view the premises are merely a temporary scaffolding for bringing the major and minor into connexion with the middle term; and this is also the reason why Aristotle recognises three syllogistic figures only, instead of the four admitted by later logicians. For, the middle may either be contained in one extreme and contain the other, which gives us the first figure; or it may contain both, which gives the second figure; or be contained in both, which gives the third; and this is an exhaustive enumeration of the possible combinations.274
