The natural frgee then consist of zero, the successor of zero onethe successor of the successor of zero twoand so on ad infinitum.

One of Frege’s stated purposes dfr to isolate genuinely logical principles of inference, so that in the proper representation of mathematical proof, one would at no point appeal to “intuition”.
