Penn Jillette, writing for NPR:
I believe that there is no God. I’m beyond atheism. Atheism is not believing in God. Not believing in God is easy — you can’t prove a negative, so there’s no work to do. You can’t prove that there isn’t an elephant inside the trunk of my car. You sure? How about now? Maybe he was just hiding before. Check again. Did I mention that my personal heartfelt definition of the word “elephant” includes mystery, order, goodness, love and a spare tire?
Believing there’s no God stops me from being solipsistic. I can read ideas from all different people from all different cultures. Without God, we can agree on reality, and I can keep learning where I’m wrong. We can all keep adjusting, so we can really communicate. I don’t travel in circles where people say, “I have faith, I believe this in my heart and nothing you can say or do can shake my faith.” That’s just a long-winded religious way to say, “shut up,” or another two words that the FCC likes less. But all obscenity is less insulting than, “How I was brought up and my imaginary friend means more to me than anything you can ever say or do.” So, believing there is no God lets me be proven wrong and that’s always fun. It means I’m learning something.
