Last Men in London

Blurb

Last Men in London is a science fiction novel by Olaf Stapledon.
The narrator is the same member of the eighteenth and final human species who purportedly induced Stapledon to write Last and First Men. Last Men in London is the story of this being's exploration of the consciousness of a present-day Englishman named Paul, from childhood through service with an ambulance crew in the First World War to adult life as a schoolteacher faced with a "submerged superman" in his class nicknamed Humpty. The inadequacies of Paul's character, the various dilemmas he has to face during his life, and the occasional influence of the advanced being who shares his experiences, provide Stapledon with a semi-autobiographical platform on which to expound his philosophical and moral beliefs.
The book includes a piece of satire on sexual morality. An unspecified future human species is presented as having an attitude to nutrition analogous to the First Men's sexual puritanism. Hence they invent mouth aprons and food privies, while having sex in public.
