After all these ages of the assiduous cultivation of literature, there has grown up in men a kind of lust of the mere art of writing, just as, after so many generations of religious training, there has grown up a passion for religious forms and observances. "Mere literature" has come to be a current phrase in criticism, meaning, I suppose, that the production to which it is applied is notable only for good craftsmanship. In the same spirit one speaks of mere scholarship, or of a certain type of man as a mere gentleman. It was mere literature that Whitman was afraid of, the æsthetic disease, the passion for letters, for poetry, divorced from love of life and of things. None knew better than he that the ultimate value of any imaginative and emotional work, even of the Bible, is its literary value. Its spiritual and religious value is inseparably connected with its literary value. "Leaves of Grass" is not bookish; it is always the voice of a man, and not of a scholar or conventional poet, that addresses us. We all imbue words more or less with meanings of our own; but, from the point of view I am now essaying, literature is the largest fact, and embraces all inspired utterances. The hymn-book seeks to embody or awaken religious emotion alone; would its religious value be less if its poetic value were more? I think not. The best of the Psalms of David, from the religious point of view, are the best from the literary point of view. What reaches and thrills the soul,--that is great art. What arouses the passions--mirth, anger, indignation, pity--may or may not be true art. No one, for instance, can read "Uncle Tom's Cabin" without tears, laughter, anger; but no one, I fancy, could ever get from it that deep, tranquil pleasure and edification that the great imaginative works impart. Keble's poetry is more obviously religious than Wordsworth's or Arnold's, but how short-lived, because it is not embalmed in the true artistic spirit! In all the great poems, there is something as deep and calm as the light and the sky, and as common and universal. I find this something in Whitman. In saying, therefore, that his aim was ulterior to that of art, that he was not begotten by the literary spirit, I only mean that his aim was that of the largest art, and of the most vital and comprehensive literature. We should have heard the last of his "Leaves" long ago had they not possessed unmistakably the vitality of true literature, "incomparable things, incomparably well said," as Emerson remarked.
