Full Idea

The vast continent of arithmetical truth cannot be brought into systematic order by laying down a fixed set of axioms and rules of inference from which every true mathematical statement can be formally derived. For some this was a shocking revelation.

Gist of Idea

Arithmetical truth cannot be fully and formally derived from axioms and inference rules
