Many people into Kierkegaard are atheists. Of course, K was not. He might find the use of his works to defend that position interesting to say the least. Much of his work really is the basis for any 'Christian Psychology' with any real depth to it. K is very tough going sometimes for several resons, and many people need an overview before diging into the source material. This author does a great job in explaining K from a religous perspective. Particularly if you are a believer, this is a great place to start. Also the 'Hong' "Esential Kierkegaard" is a great anthology.
