When I first read this quote I just went Wow! That really describes the reality so succinctly and so well. It opened my eyes then....and they are still open. Because who are we? We are the same "person" when we were a baby; when we were in school; when we became an adult; when we will be old and grey. There is something about us that stays the same even as our body changes. And that is who we really are....you can call it a soul.
The above quote is by Walter M. Miller Jr. (sometimes wrongly ascribed to C.S. Lewis) in Miller's only published novel called A Canticle for Leibowitz. Published in 1959, it won the Hugo award for best novel in 1961. It's about a post-apocalyptic society and is the compilation of 3 novellas with a number of changes so they flowed together as one novel. The 3 parts:
Miller was a science fiction short story writer in the 1950's. He first won the Hugo award in 1955 for his story "The Darfsteller". He suffered from PTSD (Post Traumatic Stress Syndrome) from his time in the Air Force on bombing missions during WWII, and was very reclusive for the rest of his life. Through his works as a artist/writer , he made a very valuable contribution. The novel really stimulates ones mind about the world.
