"I believe each individual is naturally entitled to do as he pleases with himself and the fruit of his labor, so far as it in no wise interferes with any other mans rightsthat each community, as a State, has a right to do exactly as it pleases with all the concerns within that State that interfere with the right of no other State, and that the general government, upon principle, has no right to interfere with anything other than that general class of things that does concern the whole."
