Quoting Uta Hagen:
In our search for genuine emotion and sensation and truthful behavior and action, we should never forget that *selection is our goal*. Nor should we forget the obligation to the playwright. We can perhaps aim to give even more than he had hope hoped for by our revelation of the detail of the human being he envisaged.
In defining the difference between reality in life and reality in art, Tolstoy said, „Something is added to nature which wasn’t there before.“ That „something“ is the artist’s point of view and his power of selection, which comes *from* life and makes for *new* life.
