John Polkinghorne writes in this book about science and religion as "intellectual cousins under the skin" with a common interest in understanding. The first tries to comprehend physical reality and the second focuses upon divine reality. Polkinghorne, a former Cambridge Professor of Mathematical Physics and presently an Anglican priest, sees God as the creator of a marvelously complex universe filled with mystery and countless wonders. The author accepts evil and suffering as part of "a package deal" based on human free will. Whether discussing quarks, prayer, death, or everlasting life, Polkinghorne salutes the importance of both science and religion.
