A quote from Paul Klee

"In my productive activity, every time a type grows beyond the stage of its genesis, and I have about reached the goal, the intensity gets lost very quickly, and I have to look for new ways. It is precisely the way which is productive -- this is the essential thing; becoming is more important than being.

Graphic work as the expressive movement of the hand holding the recording pencil -- which is essentially how I practice it -- is so fundamentally different from dealing with tone and colour that one can use this technique quite well in the dark, even in the blackest night. On the other hand, tone (movement from light to dark) presupposes some light, and color presupposes a great deal of light."

[1914]
