Quote in context:
I often feel, looking at Klee, that he watched himself as he worked, just to see where his mind would lead him. Working in a spirit both of rigorous formal enquiry and childlike impetuousness and spontaneity, he kept himself guessing as well as us.Another wonderful passage caught Madelaine Maior's eye:
You need to sidle up to things, let your eye snag on a detail, get sucked in then turn away again, allowing yourself to look while your mind is elsewhere. Being inattentive is as important as close inspection. An art as generative and fecund as Klee's is particularly susceptible to this kind of looking. Just follow your eye.
