I was very much on the mathematical side, where you probably do your best work before you're forty-five. Having passed that significant date, I thought I would do something else.

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.

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 and religion...are friends, not foes, in the common quest for knowledge. Some people may find this surprising, for there's a feeling throughout our society that religious belief is outmoded, or downright impossible, in a scientific age. I don't agree. In fact, I'd go so far as to say that if people in this so-called 'scientific age' knew a bit more about science than many of them actually do, they'd find it easier to share my views.

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

When you realize that the laws of nature must be incredibly finely tuned to produce the universe we see, that conspires to plant the idea that the universe did not just happen, but that there must be a purpose behind it.

The remarkable insights that science affords us into the intelligible workings of the world cry out for an explanation more profound than that which itself can provide. Religion, if it is to take seriously its claim that the world is the creation of god, must be humble enough to learn from science what that world is actually like. The dialogue between them can only be mutually enriching.
