We have merely scratched the surface of the store of knowledge which will come to us. I believe that we are now, a-tremble on the verge of vast discoveries - discoveries so wondrously important they will upset the present trend of human thought and start it along completely new lines .

I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.

The trouble with most people is that they quit before they start.

I am a vegetarian as well as a passionate anti-alcoholic, because I can thus make better use of my brain.

I never once failed at making a light bulb. I just found out 99 ways not to make one.

Good fortune is what happens when opportunity meets with planning.

I have better use for my brain than to poison it with alcohol. To put alcohol in the human brain is like putting sand in the bearings of an engine.
