Isn’t there a simple response to the materialist argument? You can say “purpose” is simply not a scientific idea. Instead, it’s an idea for theologians and philosophers to debate. Do you accept that distinction?
I sure do. But that distinction is usually violated in scientific literature and in much discussion of evolution. From the beginning of the modern world, science decided quite rightly that it wasn’t going to tackle such questions as purpose, value, meaning, importance, God, or even talk about intelligence or subjectivity. It was going to look for purely natural, causal, mechanical explanations of things. And science has every right to be that way. But that principle of scientific Puritanism is often violated by scientists who think that by dint of their scientific expertise, they are able to comment on such things as purpose. I consider that to be a great violation.

But Dawkins argues that a lot of claims made on behalf of God — about how God created the world and interacts with people — are ultimately questions about nature. Unless you say God has nothing to do with nature, those become scientific questions.
Well, I approach these issues by making a case for what I call “layered explanation.” For example, if a pot of tea is boiling on the stove, and someone asks you why it’s boiling, one answer is to say it’s boiling because H2O molecules are moving around excitedly, making a transition from the liquid state to the gaseous state. And that’s a very good answer. But you could also say it’s boiling because my wife turned the gas on. Or you could say it’s boiling because I want tea. Here you have three levels of explanation which are approaching phenomena from different points of view. This is how I see the relationship of theology to science. Of course I think theology is relevant to discussing the question, what is nature? What is the world? It would talk about it in terms of being a gift from the Creator, and having a promise built into it for the future. Science should not touch upon that level of understanding. But it doesn’t contradict what evolutionary biology and the other sciences are telling us about nature. They’re just different levels of understanding.
do you say to the atheists who demand evidence or proof of the existence of a transcendent reality?
The hidden assumption behind such a statement is often that faith is belief without evidence. Therefore, since there’s no scientific evidence for the divine, we should not believe in God. But that statement itself — that evidence is necessary — holds a further hidden premise that all evidence worth examining has to be scientific evidence. And beneath that assumption, there’s the deeper worldview — it’s a kind of dogma — that science is the only reliable way to truth. But that itself is a faith statement. It’s a deep faith commitment because there’s no way you can set up a series of scientific experiments to prove that science is the only reliable guide to truth. It’s a creed.
Are you’re saying scientists are themselves practicing a kind of religion?
The new atheists have made science the only road to truth. They have a belief, which I call “scientific naturalism,” that there’s nothing beyond nature — no transcendent dimension — that every cause has to be a natural cause, that there’s no purpose in the universe, and that scientific explanations, especially in their Darwinian forms, can account for everything living. But the idea that science alone can lead us to truth is questionable. There’s no scientific proof for that. Those are commitments that I would place in the category of faith. So the proposal by the new atheists that we should eliminate faith in all its forms would also apply to scientific naturalism. But they don’t want to go that far. So there’s a self-contradiction there.
