This is the basis for a similarly titled PBS show, where Nicholi moderated a panel of citizens with different views of god and religion. The show & book both purport to use the lives and writings of Lewis and Freud to delve into deep questions of life, spirituality, and theology. Well, sort-a. Watching only a few segments of the program made me suspicious that Nicholi was NOT as neutral as he pretends. For one thing, I would argue that Lewis is NOT a good example (let alone the greatest of the 20th century, in Nicholi's view) of thoughtful, intellectually complex christian theistic apologetics. Nor is Freud a good example (again the greatest of the 20th century to Nicholi) of deep-thinking defender of atheism. Well, the book, and further research, revealed that no, Nicholi is certainly NOT neutral. One, he himself is a psychoanalyst--skewing his viewpoint for certain--but also a politically active conservative christian (e.g., a founding member of "Family Research Council," an American conservative christian group and part of the "Focus on the Family" group). Is he blind to how he is misleading the reader/viewer, or purposefully disingenuous? I leave that to you to decide. But I do not recommend you waste your time on the book.
