Until I was twenty I was sure there was a being who could see everything I did and who didn't like most of it. He seemed to care about minute aspects of my life, like on what day of the week I ate a piece of meat. And yet, he let earthquakes and mudslides take out whole communities, apparently ignoring the saints among them who ate their meat on the assigned days. Eventually, I realized that I didn't believe there was such a being. It didn't seem reasonable. And I assumed that I was an atheist.As I understood the word, it meant that I was someone who didn't believe in a God; I was without a God. I didn't broadcast this in public because I noticed that people who do believe in a god get upset to hear that others don't. (Why this is so is one of the most pressing of human questions, and I wish a few of the bright people in this conversation would try to answer it through research.)But, slowly I realized that in the popular mind the word atheist was coming to mean something more - a statement that there couldn't be a God. God was, in this formulation, not possible, and this was something that could be proved. But I had been changed by eleven years of interviewing six or seven hundred scientists around the world on the television program Scientific American Frontiers. And that change was reflected in how I would now identify myself.The most striking thing about the scientists I met was their complete dedication to evidence. It reminded me of the wonderfully plainspoken words of Richard Feynman who felt it was better not to know than to know something that was wrong.
Drop a pebble in the water: just a splash, and it is gone;But there's half-a-hundred ripples circling on and on and on, Spreading, spreading from the center, flowing on out to the sea. And there is no way of telling where the end is going to be.Drop a pebble in the water: in a minute you forget,But there's little waves a-flowing, and there's ripples circling yet, And those little waves a-flowing to a great big wave have grown; You've disturbed a mighty river just by dropping in a stone.Drop an unkind word, or careless: in a minute it is gone;But there's half-a-hundred ripples circling on and on and on. They keep spreading, spreading, spreading from the center as they go, And there is no way to stop them, once you've started them to flow.Drop an unkind word, or careless: in a minute you forget,But there's little waves a-flowing, and there's ripples circling yet, And perhaps in some sad heart a mighty wave of tears you've stirred, And disturbed a life was happy ere you dropped that unkind word.Drop a word of cheer and kindness: just a flash and it is gone; But there's half-a-hundred ripples circling on and on and on, Bearing hope and joy and comfort on each splashing, dashing wave Till you wouldn't believe the volume of the one kind word you gave.Drop a word of cheer and kindness: in a minute you forget;But there's gladness still a-swelling, and there's joy a-circling yet, And you've rolled a wave of comfort whose sweet music can be heard Over miles and miles of water just by dropping one kind word.
