A friend recommended Olaf Stapledon’s Last and First Men. It certainly is philosophically interesting, as science fiction goes, but I don’t agree with most reviewers that it is Hegelian in spirit. I’d say it’s more Bradley than Hegel (few Brits had read Hegel in 1931 anyway), with some Nietzsche tagged on the end. Stapledon was friends with the geneticist Haldane at Oxford who was also in the CPGB, so the Hegelianism may have filtered through a certain Marxism. The Stapledon / Haldane pairing seem also to have really antagonised a certain C.S. Lewis, who created a fantasy world with divine meaning in response to their own speculations.
