Universal as are certain facts and symptoms of communities or individuals all times, there is nothing so rare in modern conventions and poetry as their normal recognizance. Literature is always calling in the doctor for consultation and confession, and always giving evasions and swathing suppressions in place of that “heroic nudity” 10 on which only a genuine diagnosis of serious cases can be built. And in respect to editions of Leaves of Grass in time to come (if there should be such) I take occasion now to confirm those lines with the settled convictions and deliberate renewals of thirty years, and to hereby prohibit, as far as word of mine can do so, any elision of them.
