The transcripts of various Congressional hearings contain many pages of fascinating information. In the following excerpts from his Doctor's thesis in political science, Mr. Hall uses the early hearings on the Atomic Energy Act and the National Science Foundation to show in what light the scientists appeared to members of Congress in the first years after the atomic bomb. That this attitude has become more realistic can be seen, for example, in the hearings before the Riehlman Committee (1954) described in an article by Edward Shils (Bulletin, December 1954). Mr. Hall sees the problem as one of differences in outlook between scientists and other members of the community. No attempt is made to inquire into the question of the extent to which the attitudes of scientists are made inevitable by the nature of science itself, for example, by the unquestionable international validity of scientific truth.
