It's a mystery. Ordinary people off the street do not usually come up with big ideas, and people who claim to have done so are mostly crackpots. But my idea seems correct and substantial. I can't see why someone famous has not pointed it out, or why that task falls to someone as ordinary as me.
The idea: a person gets a tiny pleasure when two things match or fit well, and there must be a system in one's brain that generates the pleasure-response. These pleasures are like raindrops--insignificant one at a time but we get so many that they mold our lives. For example, the pleasure of conversing: that comes partly from the pleasure you feel when what someone says fits onto something already in your mind. If we had nothing but dry conversations designed merely to transfer facts, how different our lives would be. And not only conversation--in craftsman work, poems, sports, reading, music, arts and puzzles we are motivated partly by pleasure from things fitting or matching well. You feel this kind of pleasure, you have the needed system in your brain. It nudges and cheers us a thousand times a day--if it does not, we suffer depression--it is a pervasive influence that people would do well to notice.
