Came home with Grzymala; we talked of Chopin. He said that Chopin's improvisations were far more daring than his finished compositions. They probably take the place of the sketch for a picture compared with the finished work. No! One does not spoil a painting by finishing! Perhaps there may be less scope for imagination once the work has been sketched out. You receive a different impression from a building under construction where the details are not yet shown, than from the same building when it has received its full complement of ornamentation and finish. It is the same with ruins, which appear all the more impressive because of the missing portions; their details are worn away or defaced and, as with buildings under construction, you see only rudiments and vague suggestions of mouldings and ornamentation. A finished building encloses the imagination within a circle and prevents it from straying beyond its limits. Perhaps the only reason why the sketch for a work gives so much pleasure is that each beholder can finish it as he chooses... Thus an artist does not spoil a picture by finishing it, but when he abandons the vagueness of the sketch he reveals his personality more fully, thereby displaying the full scope of his talent, but also its limitations.
