Excellent reading, folks! It's no wonder Walt Whitman was a shock to such people: he was the supreme poet of the celebration of the body in that dull age when men most wanted to deny it.
I found an interesting article on Whitman's relationship to the subject;

Although perhaps that needs it's own thread.

Edit; I've just learned that Whitman's father was a devoted student of Frances Wright, attending her lectures and subscribing to her publication. There may be a more-than-cursory connection here after all.
