From his unique perspective as both theoretical physicist and Anglican priest, Professor Polkinghorne considers aspects of quantum physics and theology, and explores the deep connections between them. With clarity, he demonstrates that these two truth-seeking enterprises engage in similar rational techniques of inquiry and share a common kinship in the search for truth.

The author identifies many parallels between quantum physics and theology, including patterns of historical development, wrestling with perplexities (such as quantum interpretation and the problem of evil) and the drive for an overarching view in the grand unified theories of physics and in Trinitarian theology. Ultimately, Polkinghorne shows that the viewpoints of theology and science are by no means mutually exclusive, for they are propelled by a desire to understand the world through experienced reality.
