David Lewis steps off a plane from Australia in 2000 and falls seriously ill. In the final year of his life, he decides to take on Christianity, but does not live long enough to write a paper, leaving only his notes. His longtime friend Philip Kitcher turns the notes into Lewis' final piece on the evil of the Christian God. In our final episode of the series, we look at the philosophy of religion and examine the lasting legacy of David Lewis. Guest voices include Steffi Lewis, Ellen Lewis, Donald Lewis, Alan Hajek, John Bigelow, Frank Jackson, Anthony Fischer, Helen Beebe, and Meghan Sullivan. The remaining episodes of Season 5 will be released bi-weekly from here on out.
