Single Idea 15211

[filed under theme 6. Mathematics / C. Sources of Mathematics / 10. Constructivism / e. Psychologism ]

Full Idea

The assumption that there is an exclusive dichotomy between the formal and the psychological is, in our view, an error of enormous consequence.

Gist of Idea

There is not an exclusive dichotomy between the formal and the logical

A Reaction

I agree entirely with this, and am opposed to the Fregean view of the matter. The psychology is the bridge between the physical world and the logic. Frege had to be a platonist, so that the formalism could latch onto something.
