Oliver Wendell Holmes, Jr., United States v. Ohio Oil Company…
“ We know that an act of legislation does not necessarily satisfy it. It may, however, be sufficient, or, to be more careful and accurate, there may be a regulation of the uses of property whose legality cannot be denied. Regulation is not a taking, and we are brought to the inquiry, what uses of property will subject it to regulation? I mean regulation in a special sense, not in the sense in which all property, whether its uses be public or private, is subject to regulation. ”
