Abstract

In “Kant on Existence, Predication, and the Ontological Argument”, Hintikka argues that the so-called “Kant–Frege view” is wrong, for its supporters erroneously assume that for Kant ‘is’ is ambiguous. In this paper, I will first critically evaluate Hintikka’s arguments against the Kant–Frege view. Then, I will attempt to prove that Kant’s claim that existence is not a real predicate and Frege’s claim that existence is a quantifier are in fact logically interdependent. Finally, I will use the Kant–Frege view in order to reconcile the various claims that Kant makes about existence.
