" This hour I tell things in confidence.
I might not tell everybody, but I will tell you.

To publish these lines is, of course, to tell everybody. Much as he wants to take us into his confidence, seduce with the warmth and directness of his voice, he's also making one of his sly jokes: he's created an intimacy with all the doors and windows open, in which you could be anyone at all. Even as I laugh at the line, I feel the gesture of his arm around my shoulder, drawing my ear nearer his mouth. What is the difference, in a poem, between performed intimacy and the real thing? What, in a work of art, is not performed? Whitman, perhaps more than any poet before him, explored and exploited poetry's strange duality. In the best poems, we feel the poet's breath, the almost-physical presence of the speaker created by all the tools at the writer's disposal. I sometimes feel that Walt has just walked into the room, as present now as he ever was, a sensual, breathing body that he somehow seems to have constructed of nothing but words. "
