learning at work

"Every film of the Cinema Novo begins at zero, like Lumiere. When filmmakers decide to begin at zero, to create a cinema with new kinds of plot, interpretation, rhythm, and poetry, they begin the dangerous and revolutionary adventure of learning at work, of uniting the parallel activities of theory and practice, of reformulating theory at the outset of each practical move, of behaving according to Nelson Pereira dos Santos' appropriate phrase, when he quotes a Portuguese poet: "I don't know where I am going; but I know where I am not going.""
