“Marxism is the opium of the intellectuals.”
Memoirs of Hecate County (1946) [New York Review Books Classics, 2004], Ch. 5, p. 340
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".
In 1955 the French philosopher Raymond Aron wrote a book on Marxism called L'Opium des intellectuels. Hence Wilson's line is often attributed to him.
