When we come under the spell of the deeper domain of technology, its economic character and even its power aspect fascinate us less than its playful side. Then we realize we that we are involved in a play, a dance of the spirit, which cannot be grasped by calculation. What is ultimately left for science is intuition alone - a call of destiny. This playful feature manifests itself more clearly in small things than in the gigantic works of our world. The crude observer can only be impressed by large quantities - chiefly when they are in motion - and yet there are as many organs in a fly as in a leviathan.
