Olaf Stapledon 
Last Men in London [EPUB ebook] 

Though this is a work of fiction, it does not pretend to be a novel. It has no hero but man. Since its purpose is not the characterization of individual human beings, no effort has been made to endow its few persons with distinctive personalities. There is no plot, except the theme of man’s struggle in this awkward age to master himself and to come to terms with the universe.
