VI. The Sustained Note; the Rest; Discords

You see, it is only when we come so far in doing such things that we reach the point where the arts should be. Philistines may think, when they see something of this kind (see Fig. 15, drawing on the left), that it is a face. It is not a face; it is a line. A face is as follows: I must manage in such a way that no actual line is drawn, but a line, as it is, is allowed to arise out of the light and shade (see drawing on the right). Anyone who draws these lines, from the very moment he begins to draw, is no painter, indeed no artist at all. Only someone who allows the lines to arise either out of the colour, or out of the chiaroscuro [light and shade], is an artist.
