Thomas Edison

I owe my success to the fact that I never had a watch. I never knew what time it was, so I never stopped working.

The greatest invention of all time is the human mind.

I am not a believer in the theory of evolution. I believe in the theory of creation. I believe that God created the world and everything in it.

I have always been a great admirer of women. I think they are the most wonderful creatures on earth. I think they are more intelligent than men. I think they are more capable than men. I think they are more practical than men.

I have never seen a man who was afraid of a woman. I have seen men who were afraid of women's tongues. I have seen men who were afraid of women's brains. I have seen men who were afraid of women's strength.

I have a theory that the human voice is immortal. It is a form of energy that never dies. It just changes form. I believe that we can record the voices of the dead and play them back.

I don't think there is any such thing as an immortal soul. I think that the soul is just a function of the brain, and when the brain dies, the soul dies. I think that the soul is just a collection of memories and experiences.

I am not a spiritualist, but I am a firm believer in the fact that we can communicate with the beyond. I believe that we can build a machine that will allow us to hear the voices of the dead.

I have friends in the other world. I have had very pleasant conversations with them. I am rather unorthodox in this matter. I believe that they are still alive and that we can communicate with them.

I am not a spiritualist. I am not a medium. I am a scientist. I am trying to build a machine to communicate with the dead. I am trying to prove that there is life after death. I am trying to prove that the soul is immortal.

We will make electricity so cheap that only the rich will burn candles.

Five percent of the people think; ten percent of the people think they think; and the other eighty-five percent would rather die than think.

Show me a thoroughly satisfied man and I will show you failure.

I am proud of the fact that I never invented weapons to kill.

All bibles are man-made.

So far as the religion of the day is concerned, it is a damned fake … Religion is all bunk.

You will have many opportunities in life to keep your mouth shut: You should take advantage of every one of them.

I owe my success to the fact that I never had a clock in my workroom. Seventy-five of us worked twenty hours every day and slept only four hours — and thrived on it.

I told [John Kruesi] I was going to record talking, and then have the machine talk back. He thought it absurd. However, it was finished, the foil was put on; I then shouted 'Mary had a little lamb', etc.

Just because something doesn't do what you planned it to do doesn't mean it's useless.
