The scientist is motivated primarily by curiosity and a desire for truth.

Happy indeed is the scientist who not only has the pleasures which I have enumerated, but who also wins the recognition of fellow scientists and of the mankind which ultimately benefits from his endeavors.

Science, almost from its beginnings, has been truly international in character. National prejudices disappear completely in the scientist's search for truth.

Only a small part of scientific progress has resulted from planned search for specific objectives. A much more important part has been made possible by the freedom of the individual to follow his own curiosity.

Medicine also disregards national boundaries.

And literature frequently rises to heights that make it international.

A chemist who does not know mathematics is seriously handicapped.
