They call for an understanding of a great number of facts. They call for decisions made on the basis of insufficient evidence. More than anything, politics calls for feeling and for compromise things that the scientist in his magnificent but sharply circumscribed field has no occasion to practice. When he deals with the intricate but consistent web of nature, he may be a genius. In the ever changing world of human relations, he is a child.
Scientists have responsibilities that are real and great.
The scientist must try to understand nature and to extend man s use of that understanding. When a scientist has learned what he can learn and built what he can build, his work is not yet done. He must also explain in clear and simple terms what he has found and what he has constructed. And there his responsibility as a scientist ends. The decision on how to use the results of science is not his.
