The world we have created is a product of our thinking; it cannot be changed without changing our thinking. If we want to change the world we have to change our thinking...no problem can be solved from the same consciousness that created it. We must learn to see the world anew.

A ship is always safe at the shore - but that is NOT what it is built for.

I learned many years ago never to waste time trying to convince my colleagues.

The ideals which have always shone before me and filled me with the joy of living are goodness, beauty, and truth. To make a goal of comfort or happiness has never appealed to me; a system of ethics built on this basis would be sufficient only for a herd of cattle.

Most mistakes in philosophy and logic occur because the human mind is apt to take the symbol for the reality.

In my relativity theory I set up a clock at every point in space, but in reality I find it difficult to provide even one clock in my room.

If my theory of relativity is proven successful, Germany will claim me as a German and France will declare me a citizen of the world. Should my theory prove untrue, France will say that I am a German, and Germany will declare that I am a Jew.
