I have five pebbles, not too different in size and weight, yet a randomness about them. If I drop them on the carpet they will scatter. Now we could run an experiment and we would find that we cannot put these pebbles in shapes that would be as elegant and as nicely related and with as great a variety as every time they fall. It is better than anything we could do. I have great respect for the way I find things. Every time something falls I look. I cannot believe the relationships. The intricacy. You hear a noise and you say ‘What is that?’ Respect for the affirmation of the unexpected.
