"Let's find and remedy all our weaknesses before our enemies get a chance to say a word. That is what Charles Darwin did. ...When Darwin completed the manuscript of his immortal book "The Origin Of Species" he realized that the publication of his revolutionary concept of creation would rock the intellectual and religious worlds.
