The progressive development of man is vitally dependent on invention.
I am unwilling to accord to some small−minded and jealous individuals the satisfaction of having thwarted my efforts. These men are to me nothing more than microbes of a nasty disease. My project was retarded by laws of nature. The world was not prepared for it. It was too far ahead of time, but the same laws will prevail in the end and make it a triumphal success.
One day man will connect his apparatus to the very wheel work of the universe. The very forces that motivate the planets in their orbits and cause them to rotate will rotate his own machinery.

Money does not represent such a value as men have placed upon it. All my money has been invested into experiments with which I have made new discoveries enabling mankind to have a little easier life.
If we use our fuel to get our power, we are living on our capital and exhausting it rapidly. This method is barbarous and wantonly wasteful, and will have to be stopped in the interest of coming generations. The heat of the sun's rays represents an immense amount of energy vastly in excess of waterpower...The sun's energy controlled to create lakes and rivers for motive purposes and transformation of arid deserts into fertile land.
The progressive development of man [has as its] ultimate purpose the complete mastery of mind over the material world.
I have been feeding pigeons, thousands of them for years. But there was one, a beautiful bird, pure white with light grey tips on its wings; that one was different. It was a female. I had only to wish and call her and she would come flying to me. I loved that pigeon as a man loves a women, and she loved me. As long as I had her, there was a purpose to my life.

This work somehow awakened my dormant powers of will and I began to practice self-control. At first my resolutions faded like snow in April, but in a little while I conquered my weakness and felt a pleasure I never knew before - that of doing as I willed.
Sometimes I feel that by not marrying, I made too great a sacrifice to my work.
Of all things I liked books best.
Man, like the universe, is a machine. Nothing enters our minds or determines our actions which is not directly or indirectly a response to stimuli beating upon our sense organs from without.
I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success ... Such emotions make a man forget food, sleep, friends, love, everything.
I am part of a light, and it is the music. The Light fills my six senses: I see it, hear, feel, smell, touch and think. Thinking of it means my sixth sense. Particles of Light are written note. A bolt of lightning can be an entire sonata. A thousand balls of lightening is a concert.. For this concert I have created a Ball Lightning, which can be heard on the icy peaks of the Himalayas.

If Mr. Edison had thought smarter he wouldn't sweat as much.
A single ray of light from a distant star falling upon the eye of a tyrant in bygone times may have altered the course of his life, may have changed the destiny of nations, may have transformed the surface of the globe, so intricate, so inconceivably complex are the processes in Nature.
