There was a whole language that I could never make function for myself; it revolved around words like 'tortured', 'struggle'. 'pain'... I could never see these qualities in paint – I could see them in life and art that illustrates life. But I could not see such conflicts in the materials and I knew that it had to be in the attitude of the painter.
