If our interpretation of the traditional doctrine of intension and extension is fair to Frege and Carnap then the whole psychologism/Platonism issue appears somewhat a tempest in a teapot as far as meaning-theory is concerned. (Of course it is a very important issue as far as general philosophy of mathematics is concerned.) For even if meanings are “Platonic” entities rather than “mental” entities on the Frege-Carnap view “grasping” those entities is presumably a psychological state (in the narrow sense). Moreover the psychological state uniquely determines the “Platonic” entity. So whether one takes the “Platonic” entity orthe psychological state as the “meaning” would appearto be somewhat a matter of convention.

And taking the psychological state to be the meaning would hardly have the consequence that Frege feared that meanings would cease to be public. For psychological states are “public” in the sense that different people (and even people in different epochs) can be in the same psychological state. Indeed Frege’s argument against psychologism is only an argument against identifying concepts with mental particulars not with mental entities in general.
