An Argument for Existentialism

Abstract

Existentialism about propositions is the view that a proposition expressed in a sentence containing a nonempty name or indexical depends ontologically on the referent of the name or indexical: the proposition could not exist if the referent did not. The paper focuses on names. It discusses some arguments for existentialism and then presents a novel one. That argument does not presuppose that propositions have constituents, and it could be accepted by those who hold broadly Fregean views about names. It shows that, for example, if Aristotle had not existed, no sentence could have meant that Aristotle is a philosopher. The paper also touches on the consequences of existentialism.
