The role of the President's science adviser, however large or small, is fraught with momentous consequences for national security. Yet all too often the subject is a neglected chapter in the literature of both science and presidential studies. In this sixth volume, the Miller Center draws on a group of the most able thinkers in the scientific community, most of whom have had experience in science advising. Their presentations, which were given in the winter and autumn of 1987, are included along with questions posed by the audience. Divided into three sectionsoPhilosophy, Practice, and Problems othe volume views science advising through the eyes of the presidency. Contents: Introduction, Kenneth W.
