Throughout the ages, many of the world's greatest thinkers have wrestled with the concept of -- and belief in -- God. It may seem unlikely that any new arguments or insights could be raised, but the twentieth century managed to produce two brilliant men with two diametrically opposed views about the question of God: Sigmund Freud and C. S. Lewis. They never had an actual meeting, but in "The Question of God," their arguments are placed side by side for the very first time.
