"The greatest invention in the world is..." - Quote by Thomas Edison

“I love great music and art, but I think 'cubist' songs and paintings are hideous.”

“I did not fail two thousand times. I merely found two thousand ways not to make a lightbulb.”

“I am 67, but I'm not too old to make a fresh start.”

“It is time for us now as a nation to exercise the same reasonable foresight in dealing with our great natural resources that would be shown by any prudent man in conserving and widely using the property which contains the assurance of well-being for himself and his children.”

“I have to say that my kids, like every child in America, is completely absorbed with Harry Potter. And so, I have gotten sucked into it, too; I can't wait for the next one to come out. I am trying to figure out what happens with Harry and Voldemort. So we have been reading that.”

“Children are people, and they should have to reach to learn about things, to understand things, just as adults have to reach if they want to grow in mental stature.”

“The pendulum of the mind alternates between sense and nonsense, not between right and wrong.”

“Let not your mind run on what you lack as much as on what you have already.”

“Nobody trips over mountains. It is the small pebble that causes you to stumble. Pass all the pebbles in your path and you will find you have crossed the mountain. The mind does not create what it perceives, anymore than the eye creates the rose.”
