I have remained a simple fellow who asks nothing of the world; only my youth is gone - the enchanting youth that forever walks on air.

If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.

The only way to escape the corruptible effect of praise is to go on working.

Understanding of our fellow human beings...becomes fruitful only when it is sustained by sympathetic feelings in joy and sorrow.

It is a miracle that curiosity survives formal education.

[When asked "Dr. Einstein, why is it that when the mind of man has stretched so far as to discover the structure of the atom we have been unable to devise the political means to keep the atom from destroying us?"] That is simple, my friend. It is because politics is more difficult than physics.

I have just got a new theory of eternity.
