Darkness and the Light' is a science-fiction novel by British writer Olaf Stapledon. In this work written during World War II, Stapledon projects two separate futures for humanity, depending not on the outcome of that particular conflict but on the failure or success of a future "Tibetan Renaissance" to influence the temper and ideology of the militaristic Russian and Chinese empires that threaten it. One of the futures involves worldwide Chinese imperialism and the subsequent degeneration and extinction of the human race, unable to defend itself against speedily evolving rats. The other ends in overthrowing the empires and creation of a worldwide socialist utopia.
