Context: When the first flint, the first shell, was shaped into a weapon, that action shaped man. As he molded and complicated his tools, so they molded and complicated him. He became the first scientific animal. And at last, via information theory and great computers, he gained knowledge of all his parts. He formed the Laws of Integration, which reveal all beings as part of a pattern and show them their part in the pattern. There is only the pattern; the pattern is all the universe, creator and created.

Context: My son's a painter. All through school his teachers tell him he's a genius. I tell him to paint me an apple that looks like and apple before he paints me one that doesn't. Go where you can go, but start from someplace recognizable. Making the simple complicated is commonplace; making the complicated simple, awesomely simple, that's creativity.
