Reality is merely an illusion albeit a very persistent one.
You cannot simultaneously prevent and prepare for war.
I do not believe that civilization will be wiped out in a war fought with the atomic bomb. Perhaps two-thirds of the people of the earth will be killed.

All that is valuable in human society depends upon the opportunity for development accorded the individual.
The man of science is a poor philosopher.
The whole of science is nothing more than a refinement of everyday thinking.
Most of the fundamental ideas of science are essentially simple and may as a rule be expressed in a language comprehensible to everyone.

Science is a wonderful thing if one does not have to earn one's living at it.
No amount of experimentation can ever prove me right a single experiment can prove me wrong.

Heroism on command senseless violence and all the loathsome nonsense that goes by the name of patriotism - how passionately I hate them!
Nationalism is an infantile disease. It is the measles of mankind.
It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature.

It's not that I'm so smart it's just that I stay with problems longer.
The difference between stupidity and genius is that genius has its limits.
To raise new questions new possibilities to regard old problems from a new angle requires creative imagination and marks real advance in science.
I am enough of an artist to draw freely upon my imagination.
Logic will get you from A to B. Imagination will take you everywhere.
The true sign of intelligence is not knowledge but imagination.
Imagination is everything. It is the preview of life's coming attractions.
Imagination is more important than knowledge.

When the solution is simple God is answering.
The distinction between the past present and future is only a stubbornly persistent illusion.
I never think of the future - it comes soon enough.

The environment is everything that isn't me.
It is a miracle that curiosity survives formal education.
Education is what remains after one has forgotten what one has learned in school.
