How much do you know about the philosophical journey of C.S. Lewis? Glenn J. Giokaris has written an interesting essay on this topic.
As many people who have read the life story of C.S. Lewis realize, at one time he was an atheist. However, for the most part, that is all that anyone knows.

Instead, it is important to view the conversion of C.S. Lewis within the context of the world around him. For Clive Staples Lewis was caught in a time of great philosophical debate at Oxford and England as a whole. Consequently, to better understand C.S. Lewis and his gradual conversion to Christianity, one must examine the philosophical battle between realism and idealism that was raging within Oxford. This battle eventually led Lewis down a road that caused him to reject both ideologies in favor of Christianity.
