Scientists need not and should not make the decisions about the uses of science and technology. Scientists have been trained in a peculiar manner. With all the elements in hand, they make a choice. It may be difficult, but it can be done. And once the solution is found, there is no doubt about it.
Political decisions call for different abilities.
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.
