Enough, perhaps, has been said of the defects of this great mass of composition, both from the point of view of our special [Sidenote: _Survey of School Rhetoric._] investigation and from more general ones. It remains to say something of its merits from the former. As will have been seen, the relations of the rhetoricians to literary criticism differ at first sight surprisingly—less so, perhaps, when they come to be examined. Sometimes the general literary view seems to be almost entirely lost in a wilderness of details and technicalities. But sometimes also the merely forensic tendency disappears, the merely technical one in the narrow sense effaces itself, and we have an almost pure treatise on Composition, limited it may be by arbitrary restrictions, conditioned by professional needs, but still Composition in general—that is to say, after a fashion, and in a manner, Literature. Every now and then, as we saw above, the writer rises to the conception of Rhetoric as Prosaics—as the other half of that Art of Literature of which Poetics is the one. And—a less good thing, but also not without its good side—we even find glimpses and glimmerings of the notion, to be taken up and widely developed later, of Rhetoric as _including_ Poetics. But the best and most important part of the matter has yet to be summarised. The technical study of Rhetoric, even when pushed to the extremities of the terminological and classifying mania, encouraged and almost necessitated constant overhauling of actual literature for examples, and encouraged the characterisation of famous authors from this point of view. Even the orators by themselves formed no inconsiderable or undistinguished _corpus_ of Greek prose literature. But, as we have seen, it was customary, even for very strict formalists, to include the historians whose connection with the orators was so close; and it was very difficult to exclude philosophical writers, especially Plato. A man must have been of preternatural stolidity if he could ransack Demosthenes and Isæus, Herodotus and Thucydides and Xenophon, Plato, and the school philosophers whom we have so freely lost, and if he did not in the process develop some notion of prose literary criticism at large, nay, formulate some rules of it. And, as we have also seen from the very first, poetry was by no means barred. The orator might very often quote it; he was constantly to go to it for suggestions of subject or treatment, beauties of style, examples of figure and form. Therefore, directly if not indirectly, the rhetorical teacher and the historical student accepted the whole of literature for their province.
