“The artist who has understood the truth about the class character of art must explain: in the interests of what class does he create his art? He is obliged to throw overboard all the insignificant theories about how art is above politics, how it exists for itself and is sufficient unto itself, how the artist is the “son of the heavens,” a celestial being, and so forth. If he is additionally convinced that his feelings and thoughts are on the side of the proletariat, then he must ask the question: how can he best “remove the veils” from surrounding reality in the interests of that class? This is by no means an idle question, especially in our era of the most strained class wars and battles. Elucidation of the truth about the class character of art would help many of today’s Soviet writers find their way in our modern literary world and avoid the errors, oftentimes very crude ones at that, which they are making.”
