Both science and religion explore aspects of reality, providing "a basis
for their mutual interaction as they present their different
perspectives onto the one world of existent reality," John Polkinghorne
argues. In One World he develops his thesis through an examination of
the nature of science, the nature of the physical world, the character
of theology, and the modes of thought in science and theology. He
identifies "points of interaction" and points of potential conflict
between science and religion. Along the way, he discusses creation,
determinism, prayer, miracles, and future life, and he explains his
rejection of scientific reductionism and his defense of natural
theology.
