I very much enjoyed my career in science. I didn't leave science because I was disillusioned, but felt I'd done my bit for it after about twenty-five years.

Science cannot tell theology how to construct a doctrine of creation, but you can't construct a doctrine of creation without taking account of the age of the universe and the evolutionary character of cosmic history.

Evolution, of course, is not something that simply applies to life here on earth; it applies to the whole universe.

Of course, nobody would deny the importance of human beings for theological thinking, but the time span of history that theologians think about is a few thousand years of human culture rather than the fifteen billion years of the history of the universe.
