The greatest discoveries will be along spiritual lines. This is the field where miracles are going to happen. Spiritual power is the greatest underdeveloped power and has the greatest future.

Education isn't play--and it can't be made to look like play. It is hard, hard work. But it can be made interesting work.

Through all the years of experimenting and research, I never once made a discovery. I start where the last man left off... All my work was deductive, and the results I achieved were those of invention pure and simple.

I was at the foot of my class.

Mr. Edison worked endlessly on a problem, using the method of elimination. If a person asked him if he were discouraged because so many attempts proved unavailing, he would say, "No, I am not discouraged, because every wrong attempt discarded is another step forward.".

It is very different to make a practical system and to introduce it. A few experiments in the laboratory would prove the practicability of system long before it could be brought into general use. You can take a pipe and put a little coal in it, close it up, heat it and light the gas that comes out of the stem, but that is not introducing gas lighting. I'll bet that if it were discovered to-morrow in New York that gas could be made out of coal it would be at least five years before the system would be in general use.

Sticking to it is the genius.
