While looking for a Jefferson quote, I happened upon this website. Note the name: "nobeliefs.com." I suppose they are unfamiliar with the Sage of Monticello’s comment: "I consider belief to be the assent of the mind to an intelligible proposition." Jefferson, of course, believed that a "Wall of Separation" was a reasonable way to disestablish religion in America precisely because he believed that the teachings of natural law were intelligible, and therefore could be comprehended by reason. He left speculative opinions outside the wall, for people to entertain in private. Nowadays, we have many Americans who believe in the wall of separation, but no longer believe in natural law. The result is what one would expect.
