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.

I'm a very passionate believer in the unity of knowledge. There is one world of reality - one world of our experience that we're seeking to describe.

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.

God didn't produce a ready-made world. The Creator has done something cleverer than this, making a world able to make itself.

Hope is much more than a mood. It involves a commitment to action.... What we hope for should be what we are prepared to work for...as far as that power lies in us.

I also think we need to maintain distinctions - the doctrine of creation is different from a scientific cosmology, and we should resist the temptation, which sometimes scientists give in to, to try to assimilate the concepts of theology to the concepts of science.

Bottom up thinkers try to start from experience and move from experience to understanding. They don't start with certain general principles they think beforehand are likely to be true; they just hope to find out what reality is like.
