John F. Kennedy, C.S. Lewis and Aldous Huxley each represented a distinctive worldview (secular humanism, Christianity and Eastern pantheism, respectively). It's remarkable that they all died on the very same day, Nov. 22, 1963.
Dr. Peter Kreeft, Professor of Philosophy at Boston College, understands well the respective worldviews each man held. Kreeft wrote a fascinating and highly entertaining imaginative book about the three meeting and conversing after death. It is titled Between Heaven and Hell: A Dialog Somewhere Beyond Death with John F. Kennedy, C.S. Lewis & Aldous Huxley. I read the book years ago and it has recently been re-issued.
Now Peter Kreeft talks about the book in a National Review Online podcast.
