This all has to do, it seems to me, with a feeling for the mystery behind phenomena….

Thus art need not be either propagandistic for contemporary politics or indifferent to them. It is essentially another expression field for something more fundamental and deep-running than either art or politics, economics, science, society or religion. It is a self-subsisting discipline, that mysterious soul-relationship to the contemporary and corresponding politics.
