 A practical proof is dramatic utility. The motions of a photoplay are in the service of the story. They should perform that work well, without waste of time and energy. An æsthetic proof is their power to stimulate our fancy and to sway our feeling. Pictorial motions should play for us, until by the illusion of art we can play with them. Another proof is reposefulness. For at the very moment when we are stimulated by art we desire to rest in satisfied contemplation. How pictorial motions may produce beauty on the screen by being at work, at play, and at rest will be told in the following chapters.
