Whitman is a poet of all the senses, but listening, it seems, engaged him with special force: many of his work's best-known passages set down what had come to him through the ear. No gesture of style so pronounced can be accidental, and I would guess that the turn toward hearing was a necessary counterweight to Whitman's extroversion. To listen means to be quiet oneself. It is an action demanding inaction, requiring reception. For a person whose genius was kinetic, whose artistic ambition was virtually all-consuming, to listen was to renounce the bounding realms of ego. The ears hear what comes from outside the self. We cannot choose to open or close them, and the sounds of the earth come to us, entering our bodies and touching the ears’ attuned bones and hairs. Whitman’s listening, then, is a kind of synecdoche for his passion: through it he invites inside himself all of existence.
