Then we shall all, philosophers, scientists and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason — for then we should know the mind of God. John Polkinghorne, Hawking’s colleague at Cambridge University, is on the one hand critical of such an approach. “What is God doing in the book at all?”. On the other hand, he is himself searching for his own very particular version of a GUT. “There is indeed a Theory of Everything, but a theory that is much grander and more comprehensive and intellectually satisfying than any Grand Unified Theory of Particle Physics could ever be”. For former particle physicist Polkinghorne, this theory is his new field of work: theology. How does he come to this? In order to understand this, this article aims first to present Polkinghorne’s key ideas in their basic development, before looking more closely at his creed.en200 - Religion::230 - Christianity & Christian theology500 - Sciencearticle10.7892/boris.119920
