The idea that theology might have something to say to science, especially if we see this as one of its responsibilities, might seem to us to be an odd question to ask. Ever since C.P. Snow proposed the idea of the ‘two cultures’, the impression of many, apart from those with a keen interest in interactions between science and religion, is that sciences are best left to their own devices. It seems obvious, at first sight, that it is primarily in the realms of history, language, literature, art and music that theology can find welcome dialogue partners. In popular culture, too, there is a residual memory that over-zealous religious fanatics in some way constricted science. The stories of conflict between Thomas Huxley and Bishop Wilberforce, Galtleo and the Holy See, have become inflated into mythologies of distrust and suspicion. The fact that the real historical accounts show many more nuances than this is important to establish, but is not really the point I am making here. Rather, I am suggesting that we have become so used to seeing the two areas of theology and science as separate, that we fail to notice in what ways the culture we live in is also one shaped by science, and that science itself is a profoundly cultural activity.
