"All art work, such as music, architecture, and even religion and the laws of science, can be understood as the transformed wish for stability and order. But art work understood as work with a substance which can be grasped and formed is more suited for the development of the taste for exploration than work in other fields, for the fact of the inherent laws of material is of importance. They introduce boundaries for a task of free imagination."
"The crafts, understood as conventions of treating material, introduce another factor: traditions of operation which embody set laws. This may be helpful in one direction, as a frame for work. But these rules may also evoke a challenge. They are revokable, for they are set by man. They may provoke us to test ourselves against them. But always they provide a discipline which balances the hubris of creative ecstasy."
"Every work of art includes the activity of performance; whichever medium it takes."
