Karl Marx, in his Critique of Hegel's Philosophy of Right (1843-4), wrote "Religion…is the opium of the people" ("Die Religion…ist das Opium des Volkes"). Wilson was not the first writer to turn Marx’s statement on its head: Evelyn Waugh published a review of Harold Laski's Faith, Reason and Civilization in The Tablet, 22nd April 1944, under the headline "Marxism, the Opiate of the People".
