According to the usual story, analytic philosophy was born when Bertrand Russell revolted against a version of Hegel’s idealism that had dominated the Cambridge philosophy scene.

Paul Redding explains how Russell’s failed attempt to use Gottlob Frege’s logic as a foundation not only for mathematics, but for the natural sciences, ended up calling for solutions found in Hegel’s philosophy.
