"But my personal religious experience of knowing and loving God is so special," believers will often say, "that I feel sorry for you atheists who have nothing like that." Oh, really? I play jazz piano.
...Suppose I were to say, "Oh, you poor non-jazz musicians; you don't know what you are missing. I can't describe it to you, and even if you listen to us you are not going to understand what is happening in our minds. It's very real and you'll just have to take our word for it."
You would understand that I am talking about something that is happening to me, not to you, and the fact that you lack my inner experience is no threat to your own self-worth or worldview. What if I were to say that the only way you can have true meaning in your life is if you practice piano for four hours a day for 20 years and learn to play jazz, like I did? You would think I was joking, or seriously deluded.
I do not deny that spiritual experiences are real. They happen all over the world, in most religions. I deny that they point to anything outside of the mind. I had many religious experiences, and I can still have them if I want. As an atheist I can still speak in tongues and "feel the presence of God."
...I know some atheists who pooh-pooh religious experiences, thinking they are all made up, purely psychological tricks of an unsophisticated mind. But they are wrong. Religious experiences are very real. I had them as a believer, and I can duplicate them as a nonbeliever.
Most of us have had convincing dreams. Suppose you had a horrible nightmare that a bogeyman was crawling in your bedroom window. You sit up screaming, waking up the rest of the house. Your hands are sweating and your heart is pounding and your breath is shallow. No one would deny that you just had a very real experience. That nightmare was a powerful moment, with physical consequences. Based on your behavior alone, we would conclude that something happened to you.
But there is no bogeyman crawling through the window. Once you realize it is a dream, you can relax and go back to sleep. That's how it is with me. I have realized that these religious experiences that I had, and can still duplicate if I should desire, are all in the mind. Of course, why would I want a phony religious experience -- especially the nightmare of hell? -- when I can have something more beautiful playing the piano?
