A must for anyone who doesn't understand atheism and doesn't want to. Be prepared to suspend disbelief and pretend that there is such a thing as an atheist world view, or that atheists share common views on anything other than their position that there is no logical reason to believe in the existence of any god or gods.
Ravi Zacharias has compiled one of the best examinations of the atheistic worldview. His book is scholarly, informative, and thought provoking. It is a must read for anyone who has questoins about the validity of atheism. I also recommend Ravi's book Can Man Live Without God?.
