Here he is on Al Jazeera, in the interview I quoted in my USA Today piece. The quotation comes at about minute 3:45. It is this:
Spirituality can mean something that I'm very sympathetic to, which is, a sort of sense of wonder at the beauty of the universe, the complexity of life, the magnitude of space, the magnitude of geological time. All those things create a sort of frisson in the breast, which you could call spirituality.
But, I would be very concerned that it shouldn't be confused with supernaturalism.
