Isaac Newton. . . Newton was an unquestioning believer in an all-wise creator of the universe, and in his own inability - like the boy on the seashore - to fathom the entire ocean in all its depths. He therefore believed that there were not only many things in heaven beyond his philosophy, but plenty on earth as well, and he made it his business to understand for himself what the majority of intelligent men of his time accepted without dispute (to them it was as natural as common sense) - the traditional account of the creation.
