Parable of the Klee ...

“The artist has studied this world of variety and has, we may suppose, unobtrusively found his way in it. His sense of direction has brought order into the passing stream of image and experience. This sense of direction in nature and life, this branching and spreading array, I shall compare with the root of the tree. From the root the sap flows to the artist, flows through him, flows to his eye. Thus he stands as the trunk of the tree. Battered and stirred by the strength of the flow, he guides the vision on into his work. As, in full view of the world, the crown of the tree unfolds and spreads in time and space, so with his work. Nobody would affirm that the tree grows its crown in the image of its root.… Different functions expanding in different elements must produce divergences. [The artist], standing at his appointed place, the trunk of the tree, he does nothing other than gather and pass on what comes to him from the depths. He neither serves nor rules – he transmits. His position is humble. And the beauty at the crown is not his own. He is merely a channel.”

(Paul Klee, On Modern Art.)
