Could you explain Christopher Caudwells Marxist understanding of art based on dialogue?

Martin Krenn: Neala Schleuning

There is a very interesting quote of the Marxist theoretician Christopher Caudwell in your book: “All art is conditioned by the concept of freedom which rules in the society that produces it; art is a mode of freedom, and a class society conceives freedom to be absolutely whatever relative freedom that class has attained to. In bourgeois art man is conscious of the necessity of outer reality, but not of his own, because he is unconscious of the society that makes him what he is. He is only a half-man.” Christopher Caudwells, Illusion and Reality (1937). Caudwell is a theoretician of the 1930s and widely forgotten. Could you explain his understanding of art? How it is based on a dialogue with the public and on exchange with ordinary life.
