Chamberlain's book demonstrates the folly of trying to formulate an objective morality apart from an ultimate, absolute and personal standard. The book is entertaining in its Socratic dialogue format. The author gives a fair presentation of the non-theistic systems of ethics and carefully demonstrates why they cannot yield a true morality. Chamberlain doesn't deny that non-theists can be moral. He simply demonstrates why their morality has no rational basis. If you're interested in Christian apologetics of this kind, you might read Peter Kreeft's (Catholic) books, Socrates Meets Jesus, The Unaborted Socrates, and Between Heaven and Hell. All are written in a similar, Socratic style, but Kreeft's are as funny as they are intellectually stimulating. Chamberlain's and Kreeft's books are a great addition to any library. ~ An Amazon Reader
