H. L. Mencken,
The American Language — The Language in the Making
(1919)
“ When the rest of literary America was still indulging in the polite language of pulpits and the lifeless rhetoric of its libraries, Whitman not only sensed the richness and vigor of the casual word, the colloquial phrase—he championed the vitality of slang, the freshness of our quickly assimilated jargons, the indigenous beauty of vulgarisms. He even predicted that no future native literature could exist that neglected this racy speech, that the vernacular of people as opposed to the language of literati would form the living accents of the best poets to come. ”
