Was Walt Whitman an Anarchist?

I saw this quote once and it intrigued me. I even sometimes include it as a signature for outgoing mail But the more I look at it the more I realize it could be taken in several ways. Does anybody know? Was he an anarchist?

Here is the quote:

“The shallow consider liberty a release from all law, from every constraint. The wise see in it, on the contrary, the potent Law of Laws.”
– Walt Whitman (“Notes Left Over” 1881)
