The late Mrs. Thomas A. Edison told me that when her famous husband was dying he whispered to his physician: “It is very beautiful over there.” Edison was the world’s greatest scientist. All his life he had worked with phenomena. He was of a factual cast of mind. He never reported anything as a fact until he saw it work. He would never have reported: ‘It is very beautiful over there’ unless, having seen, he knew it to be true.
