Bones are coordinated to form the skeleton.
Even at rest they depend on mutual support.
This is furnished by the ligaments.
Theirs is a secondary function; one could speak of a hierarchy of function.
The next step in motoric organization leads from bone to muscle. The tendon is the mediary between these two.

And now an altogether revolutionary discovery: to adapt oneself to the contents of the paintbox is more important than [to] nature and its study. I must some day be able to improvise freely on the chromatic keyboard of the rows of watercolor cup.

The artist does not ascribe to the natural form of appearance the same convincing significance as the realists who are his critics. He does not feel so intimately bound to that reality, because he cannot see in the formal products of nature the essence of the creative process. He is more concerned with formative powers than with formal products.
