Science and Spirit interview (2004)
Context: A great many people say we have language and imagination to posit creators, interveners, and agencies that we can't actually prove. And yet some people experience God within them--these experiences are not drawn-up hypotheses. It's possible those of us who don't feel God within them have deficient brains that aren't capable of such experiences; or alternatively, the people who experience these things have brains that somehow create them. As near as I can tell, the jury is out on that. I may be a non-theist who doesn't include a god concept in my religious orientation because I have an incompetent brain, or perhaps theists have brains giving them inaccurate information.
