  • Examples of the second sort of fact, social facts, are that this piece of paper is a five dollar bill, that he is a citizen of the U. S., that the New York Giants won the 1991 Superbowl, and that he owns a piece of property in Berkeley, CA. Of course, in order to state facts we need the existence of language, a social fact, but the facts we state can be distinguished from our statement of them.
