Full Idea
Russell sought what was common to Euclidean and non-Euclidean systems, found it in the axioms of projective geometry, and took a Kantian view of them.
Clarification
A 'Kantian' view relies on intuition
Gist of Idea
Geometry is united by the intuitive axioms of projective geometry

A Reaction
Russell's work just preceded Hilbert's famous book. Tarski later produced some logical axioms for geometry.
