Mathematics knows no races or geographic boundaries; for mathematics, the cultural world is one country.

My country is the world, and my religion is to do good.

And so, my fellow Americans: ask not what your country can do for you — ask what you can do for your country.

My fellow citizens of the world: ask not what America will do for you, but what together we can do for the freedom of man.

I believe it is the duty of each of us to act as if the fate of the world depended on him. Admittedly, one man by himself cannot do the job. However, one man can make a difference… We must live for the future of the human race, and not for our own comfort or success.
