If one does not understand the usefulness of the useless and the uselessness of the useful, one cannot understand art.
The Arts are man's most useless ... and essential ... activity.
A work of art is above all an adventure of the mind.
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.
I believe that in the history of art and of thought there has always been at every living moment of culture a will to renewal. This is not the prerogative of the last decade only. All history is nothing but a succession of crises - of rupture, repudiation and resistance. When there is no crisis, there is stagnation, petrifaction and death. All thought, all art is aggressive.
