I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.

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.

I never pick up an item without thinking of how I might improve it. I never perfected an invention that I did not think about in terms of the service it might give others. I want to save and advance human life, not destroy it. I am proud of the fact that I never invented weapons to kill. The dove is my emblem.

Do the thing and the power will come.

I think work is the world's greatest fun.

I believe that the science of chemistry alone almost proves the existence of an intelligent creator.

The most necessary task of civilization is to teach people how to think. It should be the primary purpose of our public schools. The mind of a child is naturally active, it develops through exercise. Give a child plenty of exercise, for body and brain. The trouble with our way of educating is that it does not give elasticity to the mind. It casts the brain into a mold. It insists that the child must accept. It does not encourage original thought or reasoning, and it lays more stress on memory than observation.
