Perhaps we will find it convenient here, too, to base perfectly clear ideas of the three existing schools of novel-writing upon these foregoing principles. It has been common for some time to hear of the Romantic and the Realistic school, and lately a third term has been brought into use by the Zola section who call themselves the Naturalistic school. It is easy to see that these terms have arisen from the greater or less prominence given now to the poetic activity, now to the scientific activity, in novel writing; those who most rely on the poetic being the Romantic, those on a combination of the poetic and scientific the Realistic, and those who entirely reject the imagination (as Zola professes to do) the Naturalistic school. At all events, then, not troubling ourselves with the Naturalists who, as we have seen, call that an experiment which is only an imaginative product; we are prepared to study the Novel as a work in which science is carried over into the region of art. We are not to regard the novel therefore as ought else but a work of art, and the novelist as an artist. One rejoices to find Emerson discussing the novel in this light purely, in his very suggestive essay on "Books":-- "Whilst the prudential and economical tone of society starves the imagination, affronted Nature gets such indemnity as she may. The novel is that allowance and frolic the imagination finds. Everything else pins it down, and men flee for redress to Byron, Scott, Disraeli, Dumas, Sand, Balzac, Dickens, Thackeray and Reade. "The imagination infuses a certain volatility and intoxication. It has a flute which sets the atoms of our frame in a dance, like planets; and, once so liberated, the whole man reeling drunk to the music, they never quite subside to their old stony state." Nay, we have such beautiful novels in the world, novels far from the experimental romances by which we are not _perfected_ but _infected_ (_non perficitur_, _inficitur_), as old Burton quotes in the _Anatomy_; novels in which scientific harmony has passed into its heavenly after-life of wisdom, novels in which the pure sense of poetic beauty is so tenderly drawn out, that I love to think of them in the terms which our most beauty-loving of modern poets has applied to beauty, in the opening of _Endymion_:
