Why It's So Hard for Scientists to Believe in God
So if you want to answer questions about how nature works, how biology works, for instance, science is the way to get there. Scientists believe in that, and they are very troubled by a suggestion that other kinds of approaches can be taken to derive truth about nature. And some I think have seen faith as therefore a threat to the scientific method and therefore to be resisted.
But faith in its perspective is really asking a different set of questions. And that’s why I don’t think there needs to be a conflict here. The kinds of questions that faith can help one address are more in the philosophical realm. Why are we all here? Why is there something instead of nothing? Is there a God? Isn’t it clear that those aren't scientific questions and that science doesn’t have much to say about them? But you either have to say, well those are inappropriate questions and we can’t discuss them, or you have to say, we need something besides science to pursue some of the things that humans are curious about.
