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.

The distinction between the past, present and future is only a stubbornly persistent illusion.

The unleashed power of the atom has changed everything save our modes of thinking and we thus drift toward unparalleled catastrophe.

I never think of the future - it comes soon enough.

Coincidence is God's way of remaining anonymous.

When the solution is simple, God is answering.

I do not believe in the God of theology who rewards good and punishes evil.

I want to know all Gods thoughts; all the rest are just details.

God does not play dice.

We should take care not to make the intellect our god; it has, of course, powerful muscles, but no personality.

Great spirits have always encountered violent opposition from mediocre minds.

Nationalism is an infantile disease. It is the measles of mankind.

All that is valuable in human society depends upon the opportunity for development accorded the individual.

The devil has put a penalty on all things we enjoy in life. Either we suffer in health or we suffer in soul or we get fat.

Only one who devotes himself to a cause with his whole strength and soul can be a true master. For this reason mastery demands all of a person.

The true sign of intelligence is not knowledge but imagination.

The difference between stupidity and genius is that genius has its limits.

He who joyfully marches to music in rank and file has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would suffice.

Joy in looking and comprehending is nature's most beautiful gift.

Imagination is more important than knowledge.

Information is not knowledge.

Knowledge of what is does not open the door directly to what should be.

There comes a time when the mind takes a higher plane of knowledge but can never prove how it got there.

The only reason for time is so that everything doesn't happen at once.

I have just got a new theory of eternity.

Reality is merely an illusion, albeit a very persistent one.

The hardest thing to understand in the world is the income tax.

The attempt to combine wisdom and power has only rarely been successful and then only for a short while.

Look deep into nature, and then you will understand everything better.

Pure mathematics is, in its way, the poetry of logical ideas.

Occurrences in this domain are beyond the reach of exact prediction because of the variety of factors in operation, not because of any lack of order in nature.

We still do not know one thousandth of one percent of what nature has revealed to us.

Peace cannot be kept by force; it can only be achieved by understanding.

Politics is for the present, but an equation is for eternity.

I am not only a pacifist but a militant pacifist. I am willing to fight for peace. Nothing will end war unless the people themselves refuse to go to war.

Force always attracts men of low morality.

If you are out to describe the truth, leave elegance to the tailor.

Heroism on command, senseless violence, and all the loathsome nonsense that goes by the name of patriotism - how passionately I hate them!

Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either.

In matters of truth and justice, there is no difference between large and small problems, for issues concerning the treatment of people are all the same.

If we knew what it was we were doing, it would not be called research, would it?

It is strange to be known so universally and yet to be so lonely.

Anger dwells only in the bosom of fools.

When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity.

Common sense is the collection of prejudices acquired by age eighteen.

God always takes the simplest way.

That deep emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.

Imagination is everything. It is the preview of life's coming attractions.

I cannot imagine a God who rewards and punishes the objects of his creation and is but a reflection of human frailty.

Life is like riding a bicycle. To keep your balance, you must keep moving.
