"great artists can be uncertain. Of course they are while strugggling to find solutions. Tolstoi's scripts are almost indecipherable. Emily Dickinson provided four or more alternates for every word; Beethoven wrestled with endings to the point of exhaustion; in our day Jerome Robbins and his lack of decision are a byword in the dance profession. But all of these knew very well what they did not want, and what they did not want was the current coin, the well-worn usage. What they wanted was something newly experienced, and therefore unknown and hard to attain."
