Surrealists, who aspire to be cultural radicals, even revolutionaries, have often been under the well-intentioned illusion that they could be, indeed should be, Marxists. But Surrealist aestheticism is too suffused with irony to be compatible with the twentieth century’s most seductive form of moralism. Marx reproached philosophy for only trying to understand the world rather than trying to change it. Photographers, operating within the terms of the Surrealist sensibility, suggest the vanity of even trying to understand the world and instead propose that we collect it.
