The object of literature is not dissimilar from these. Literature aims at releasing the emotions that arise from the formed words of a certain language. But literature is probably a less pure—and hence more universal—art than any I have yet examined. For it must be apparent to all minds that not only is a word a definite symbol of some fact, but also it is a thing capable of being spoken or sounded. The art of literature, then, in so far as it deals with definite statements, is akin to painting or photography: in so far as it deals with sounded words, it is akin to music.

Literature, therefore, does not depend on the peculiar twists and quirks which represent, to those who can read, the words, but rather on the essential words themselves. In fact, literature existed before writing; and writing in itself is of no value from the purely literary sense, except in so far as it preserves and transmits from generation to generation the literary emotion. Style, whether in prose or poetry, is an attempt to develop this essentially musical quality of literature, to evoke the magic that exists in the sound-quality of words, as well as to combine these sound-qualities in definite statements or sentences. The difference between prose and poetry is, therefore, not a difference of means, but of psychological effect and reaction. The means employed, the formed language, is the same: but the resultant impression is quite different.
In prose, the emotions expressed are those that are capable of development in a straight line. In so far as prose is pure, it confines itself to the direct orderly progression of a thought or conception or situation from point to point of a flat surface. The sentences, as they develop this conception from its beginning to conclusion, move on, and do not return upon themselves. The grouping of these sentences into paragraphs gives the breadth of the thought. The paragraphs, sections, and chapters are each a square, in that they represent a division of the main thought into parallel units, or blocks of subsidiary ideas. The sensation of depth is finally obtained by arranging these blocks in a rising climacteric progression, or in parallel lines, or in a sort of zigzag figure.
The psychological reaction that arises from the intelligent appreciation of poetry is quite different. In poetry, we have a succession of curves. The direction of the thought is not in straight lines, but wavy and spiral. It rises and falls on gusts of strong emotion. Most often it creates strongly marked loops and circles. The structure of the stanza or strophe always tends to the spherical. Depth is obtained by making one sphere contain a number of concentric, or overlapping spheres.
Hence, when we speak of poetry we usually mean regular rhyme and metre, which have for so long been considered essential to all poetry, not as a device for heightening musical effect, as so many people suppose, but merely to make these loops and circles more accentuated, and to make the line of the poem turn upon itself more recognizably. But it must be recognized that just as Giotto's circle was none the less a circle, although not drawn with compasses, so poetic circles can be constructed out of subtler and more musical curves than that which painstakingly follows the selfsame progression of beats, and catches itself up on the same point of rhyme for line after line. The key pattern on the lip of a Greek vase may be beautiful, but it is less beautiful, less satisfying, and less conclusive a test of artistic ability than the composition of satyrs and of mænads struggling about the centre. Therefore I maintain, and will continue to do so, that the mere craftsman-ability to write in regular lines and metres no more makes a man a poet than the ability to stencil wall-papers makes him a painter.
Rather is it more important to observe that almost any prose work of imaginative literature, if examined closely, will be found to contain a plentiful sprinkling of excellent verses; while many poems which the world hails as master-pieces, contain whole pages of prose. The fact is, that prose and poetry are to literature as composition and colour are to painting, or as light and shadow to the day, or male and female to mankind. There are no absolutely perfect poets and no absolutely perfect prose-writers. Each partakes of some of the characteristics of the other. The difference between poetry and prose is, therefore, a difference between a general roundness and a general squareness of outline. A great French critic, recently dead, who devoted perhaps the major part of his life to the study of the æsthetics of the French tongue, declared that Flaubert and Chateaubriand wrote only poetry. If there are those who cannot see that in the only true and lasting sense of the word poetry, this remark was perfectly just, then all I have written above will be in vain.

Along with the prevailing preoccupation with technique which so marks the early twentieth century, there has gone also a great change in the subject-matter of art. Having tried to explain the aesthetic form-basis of poetry, I shall now attempt to explain my personal way of viewing its content.
It is a significant fact that every change in technical procedure in the arts is accompanied by, and grows out of, a change in subject-matter. To take only one out of innumerable examples, the new subject-matter of Wagner's music-dramas, of an immeasurably higher order than the usual libretto, created a new form of music, based on motifs, not melodies. Other examples can easily be discovered. The reason for this is not difficult to find.
