Contact with other artists has always been of great importance to me. When the artists I know best used to meet.... the talk was mostly of ideas in painting. There was an unconscious collaboration between artists. Whether you agreed or disagreed was of no consequence. It was exciting and you were compelled to paint over your head.... If your painting was criticized adversely, you either imitated someone to give it importance, or you simply suffered and painted harder to make your feelings on canvas convincing... What does happen when artists meet is that we are able to see more clearly the unfolding of character as time goes on.
