But not only medicine, engineering, and painting are arts; living itself is an art - in fact, the most important and at the same time the most difficult and complex art to be practised by man. Its object is not this or that specialised performance, but the performance of living, the process of developing into that which one is potentially. In the art of living, man is both the artist and the object of his art; he is the sculptor and the marble; the physician and the patient.
