With Savages, The Weak In Body Or Mind Are Soon Eliminated. We Civilized Men, On The Other Hand, Do Our Utmost To Check The Process Of Elimination. We Build Asylums For The Imbecile, The Maimed And The Sick. Thus The Weak Members Of Civilized Societies Propagate Their Kind.

The Explanation Lies, As I Believe, In The Extreme Imperfection Of The Geological Record.
