Invention is the most important product of man's creative brain. The ultimate purpose is the complete mastery of mind over the material world, the harnessing of human nature to human needs.

My ear barely caught signals coming in regular succession which could not have been produced on earth.

To stop war by the perfection of engines of destruction alone, might consume centuries and centuries. Other means must be employed to hasten the end.

The scientists from Franklin to Morse were clear thinkers and did not produce erroneous theories. The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane. Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.

My belief is firm in a law of compensation. The true rewards are ever in proportion to the labour and sacrifices made.

But I hope that it will also be demonstrated soon that in my experiments in the West I was not merely beholding a vision, but had caught sight of a great and profound truth.

When wireless is fully applied the earth will be converted into a huge brain, capable of response in every one of its parts.
