“Thought” is somewhat briefly referred to Rhetoric (_vide infra_), and then we come to Diction. This is treated rather oddly, though the oddity will not seem so odd to those who have carefully studied the contents, still more the texts, of the foregoing chapter. Much of the handling is purely grammatical. The “Figures,” especially metaphor, make some appearance: and of style proper we hear little more than that it is to be clear without being mean, though we have some illuminative examples of this difference. Then Aristotle passes briefly to Epic, his prescription for which is an application of that already given—the single action, with its beginning, middle, and end. The organism, with its _oikeia hedone_, the parts, the kinds are the same, with the exception of song and scenery. The only differences are scale (Epic being much larger) and metre, with a fuller allowance for the improbable, the irrational. Some rather desultory remarks on difficulties of criticism or interpretation follow, and the piece ends abruptly with a consideration of the purely academic question whether Epic or Tragedy ranks higher. Some had given the primacy to Epic: Aristotle votes for Tragedy, and gives his reasons. This summary has been cut down purposely to the lowest point consistent with sufficiency and clearness; but I trust it is neither insufficient nor obscure. We may now see what can be observed in it. We observe, in the first place, not merely a far fuller dose of criticism than in anything studied hitherto, but also a great [Sidenote: _Characteristics, general._] advance of critical _theory_. Not only has the writer got beyond the obscure, fragmentary, often irrelevant, utterances of the early philosophers: but he is neither conducting a particular polemic, as was Aristophanes, nor speaking to the previous question, like Plato. An _a posteriori_ proof of the depth and solidity of the inquiry may be found in the fact that it is still, after more than two thousand years, hardly in the least obsolete. But we are not driven to this: its intrinsic merit is quite sufficient. At the same time, there are certain defects and drawbacks in it which are of almost as much importance as its merits, and which perhaps require prior treatment. That it is incomplete admits of no doubt; that part of it shows signs of corruption, that there are possible garblings and spurious insertions, does not admit of very much. But the view throughout is so firm and consistent; the incidental remarks tally so well with what we should expect; and, above all, the exclusions or belittlings are so significant, that if the treatise were very much more complete, it would probably not tell us very much more than we know or can reasonably infer already.
