Why do you call yourself an atheist? Why not an agnostic?
Well, technically, you cannot be any more than an agnostic. But I am as agnostic about God as I am about fairies and the Flying Spaghetti Monster. You cannot actually disprove the existence of God. Therefore, to be a positive atheist is not technically possible. But you can be as atheist about God as you can be atheist about Thor or Apollo. Everybody nowadays is an atheist about Thor and Apollo. Some of us just go one god further.
When you're talking about God, are you really talking about the God of the Bible -- Yahweh of the Old Testament?
Well, as it happens, I am because I have an eye to the audience who's likely to be reading my book. Nobody believes in Thor and Apollo anymore so I don't bother to address the book to them. So, in practice, it's addressed to believers in the Abrahamic God.

Now, there are an awful lot of people who call themselves religious -- or some people prefer to use the word "spiritual" -- even though they don't go to church. They aren't part of any organized religion. They don't believe in a personal God. Some don't even like the word "God" because there's so much baggage attached to that word. But they still have some powerful feeling that there is a transcendent reality. And they often engage in some spiritual practice in their own lives. Would you call these people "religious"?
That's a difficult question. I probably would call them religious. It depends on exactly what they do believe. The first chapter of "The God Delusion" talks about Einstein, who often used the word "God." Einstein clearly was an atheist in the sense that he didn't believe in any sort of personal God. He used the word "God" as a metaphoric name for that which we don't yet understand, for the deep mysteries at the foundation of the universe.
But I think most people would call Einstein a deist. He suggested that God may have created the laws of nature, the laws of physics, to get the universe started.
Some people have maintained that position. My judgment, reading what Einstein said, is that he was not a deist. He certainly believed in some sort of deep mystery, as do I. And it is possible to use the word "religious" to describe such a person. On that basis, one could even say that I am a religious person or Carl Sagan was a religious person. But for me, the divide comes with whether you believe there is some kind of a supernatural, personal being. And I think deists, as well as theists, believe that. By that criterion, I don't think Einstein was a deist. He certainly wasn't a theist, although the language he used might lead you to think he was. I think it's misleading to use a word like "God" in the way Einstein did. I'm sorry that Einstein did. I think he was asking for trouble, and he certainly was misunderstood.
Your definition of religious belief seems to involve a personal being. I think a lot of people would disagree. They may consider themselves strongly religious, but they would regard the whole idea of a personal God to be an outdated notion of what religion is.
Well, then I would want to know what they did mean by it. I would take my stand on whether the god or the being -- whatever we're talking about -- is complicated and improbable and has those attributes of a person -- intelligence, creativity, something of that sort. If you believe that the universe was created by a designing intelligence, whether you call that personal or not, that seems to me to be a good definition of God. That's what I don't believe in. And that's what Einstein did not believe in.
Once you get past the biblical literalists, I think most people assume that science and religion are actually quite compatible. Stephen Jay Gould famously argued that they were "non-overlapping magisteria": Science covers the empirical realm of facts and theories about the observable universe, and religion deals with ultimate meaning and moral value. But you're very critical of this argument, right?
Yes, I think religious belief is a scientific belief, in the sense that it makes claims about the universe which are essentially scientific claims. If you believe the universe was created and inhabited by a supreme being, that would be a very different kind of universe from the sort of universe that wasn't created and does not house a creative intelligence. That is a scientific difference. Miracles. If you believe in miracles, that is clearly a scientific claim, and scientific methods would be used to evaluate any miracle that somebody claimed evidence for.
Suppose, hypothetically, that forensic archaeologists, in an unlikely series of events, gained evidence -- perhaps from some discovered DNA -- which showed that Jesus did not really have an earthly father, that he really was born of a virgin. Can you imagine any theologian taking refuge behind Stephen Jay Gould's non-overlapping magisteria and saying, "Nope, DNA evidence is completely irrelevant. Wrong magisterium. Science and religion have nothing to do with each other. They just peacefully coexist." Of course they wouldn't say that. If any such evidence were discovered, the DNA evidence would be trumpeted to the skies.
