"Yesterday, a long conversation in Brecht’s sickroom about my essay "The Author as Producer." Brecht thought the theory I develop in the essay — that the attainment of technical progress in literature eventually changes the function of art forms (hence also of the intellectual means of production) and is therefore a criterion for judging the revolutionary function of literary works — applies to artists of only one type, the writers of the upper bourgeoisie, among whom he counts himself. "For such a writer," he said, "there really exists a point of solidarity with the interests of the proletariat: it is the point at which he can develop his own means of production. Because he identifies with the proletariat at this point, he is proletarianized — completely so — at this same point, i.e. as a producer. And his complete proletarianization at this one point establishes his solidarity with the proletariat all along the line.""
