Leaves of Grass is one book that Whitman rewrote and enlarged for almost forty years, beginning with a thin 1855 edition and ending with the full sequence preserved here. Rather than telling a story, it is a gathering of songs, arranged into clusters such as Inscriptions, Children of Adam, Calamus, Drum-Taps, and Songs of Parting, all spoken in the long, unrhymed, surging lines that became his signature.
Its center is the sprawling poem Song of Myself, which announces the book's whole project in its first words. The speaker celebrates himself and sings himself, loafs and invites his soul, and declares that the atoms of his body are shared with the reader. From this single ordinary self the poem expands outward until it claims to contain and speak for everyone.
Whitman writes the body and the natural world with deliberate frankness. He calls himself the poet of the Body and of the Soul at once, praises physiology from top to toe, and sings the female equally with the male. Grass, sea, soil, breath, and sex are not lower than spirit in his account; they are where spirit is found, and he describes himself as a kosmos, turbulent and fleshy, no stander above other people or apart from them.
The method that carries this vision is the catalogue: page-long lists in which the contralto, the carpenter, the pilot, the lunatic, the bride, the slave at auction, and dozens more appear in rapid succession, each line a small open window. By naming so many different lives side by side and giving them equal weight, the poems enact the democracy they preach, refusing to accept anything that all cannot share on the same terms.
Running underneath is a settled answer to mortality. A child asks what the grass is, and the poet, unable to answer plainly, guesses it is the beautiful uncut hair of graves, the dead returning as new growth. He insists the smallest sprout shows there is really no death and that all goes onward and outward. The book ends as it sounds its barbaric yawp and then departs like air, bequeathing the poet to the dirt to grow from the grass, waiting somewhere for the reader to catch up.
