Superb interview in this month's National Geographic with Scientist/Christian Francis Collins.

Horgan: What do you think about the field of neurotheology, which attempts to identify the neural basis of religious experiences?

Collins: I think it's fascinating but not particularly surprising. We humans are flesh and blood. So it wouldn't trouble me—if I were to have some mystical experience myself—to discover that my temporal lobe was lit up. That doesn't mean that this doesn't have genuine spiritual significance. Those who come at this issue with the presumption that there is nothing outside the natural world will look at this data and say, "Ya see?" Whereas those who come with the presumption that we are spiritual creatures will go, "Cool! There is a natural correlate to this mystical experience! How about that!"
