As this study traces the history of the dramatic intra-scientific conflict over nuclear weapons which has developed since World War II, it analyzes the politically relevant ideas, attitudes, and behavior of those scientists who have been influential in the formulation of American policy toward nuclear weapons. The author contends that the emergence of the scientist into the mainstream of American political life is one of the great events of our history. As he assays the situation, he emphasizes the growing need for effective measures for integrating scientist-advisers into national policy-making processes. This well documented book will be of lasting value to both scientists and public administrators, and it will be of vital interest to all concerned with current problems of the nuclear era.
