Jack, Aldous and Jack

Our problems are man-made, therefore they may be solved by man. And man can be as big as he wants. No problem of human destiny is beyond human beings. — John F. Kennedy*  

There's only one corner of the universe you can be certain of improving, and that's your own self. — Aldous Huxley  

Fallen man is not simply an imperfect creature who needs improvement: he is a rebel who must lay down his arms. — C. S. Lewis*  

Kennedy, Huxley and Lewis all died on the same day, November 22, 1963. This interesting factoid prompted a great book by Peter Kreeft, Between Heaven and Hell: A Dialog Somewhere Beyond Death with John F. Kennedy, C. S. Lewis & Aldous Huxley.  Kreeft says in the foreword: 

"It would be part of “The Great Conversation” that has been going on for millennia. For these three men represented the three most influential philosophies of life in our human history: ancient Western theism (Lewis), modern Western humanism (Kennedy) and ancient Eastern pantheism (Huxley).
These three men also represented the three most influential versions of Christianity in our present culture: traditional, mainline or orthodox
Christianity (what Lewis called “mere Christianity”), modernist or humanistic Christianity (Kennedy), and Orientalized or mystical Christianity (Huxley)."

*Both Kennedy and Lewis were called Jack by family and friends.
