Do scientists have a unique responsibility to society, and if so what is the character of this obligation? This is a practical question for those who are torn between a desire to devote themselves exclusively to science and an urge to promote the political and educational activity undertaken after the war. We present varying points of view on this problem, in the form of comments on a speech delivered by Dr. Bridgman before the A.A.A.S. in December, 1946. Dr. Oppenheimer's article on Page 64 bears in part upon the same subject. Dr. Bridgman is Hollis Professor of Mathematics and Natural Philosophy at Harvard, and received the Nobel Prize for Physics in 1946 for his work in the field of high pressures. His speech is reprinted from THE SCIENTIFIC MONTHLY for August 1947 by the kind permission of its editors.
