I’ve just received a copy of Logos, the official journal of the C. S. Lewis Society of California. It has some interesting Lewis-related articles. Here are a couple of links to articles in the journal and another giving details of the society itself:

“The Argument from Reason,” by Victor Reppert

“The Ultimate Question of Origins: God and the Beginning of the Universe,” by William Lane Craig
