If you are going to tell people the truth, you had better make them laugh or they will kill you.
Every work of art (unless it is a psuedo-intellectualist work, a work already comprised in some ideology that it merely illustrates, as with Brecht ) is outside ideology, is not reducible to ideology. Ideology circumscribes without penetrating it. The absence of ideology in a work does not mean an absence of ideas; on the contrary it fertilizes them.
