I am reminded of four definitions: A Radical is a man with both feet firmly planted—in the air. A Conservative is a man with two perfectly good legs who, however, has never learned to walk forward. A Reactionary is a somnambulist walking backwards. A Liberal is a man who uses his legs and his hands at the behest—at the command—of his head.
