AMERICAN ASSOCIATION FORTHE ADVANCEMENT OF SCIENCEScience serves its readers as a forum for the
presentation and discussion of important issuesrelafed to the advancement of science, includingthe presentation of minority or conflicting pointsof view, rather than by publishing only materialon which a consensus has been reached. Accord-ingly, all articles published in Science-includingeditorials, news and comment. and book reviews-are signed and reflect the individual views of theauthors and not official points of view adopted- bythe AAAS or the institutions with which the authorsare affiliated.

NSF: A Look AheadOne cannot long occupy the director's chair at the National Science
Foundation without being struck by the fact that creative science in theUnited States is in a state of transition. And much of the feedback as-sociated with this fermentation is focused on NSF, which in this countryis often equated with creative science and scientists.
Science, as one of man's highest and greatest intellectual achievements,has had a pervasive and protracted influence on man, his way of life, andhis environment. And nowhere has its power for change been so dramaticas in the United States. Most scientists hold that the destructive forces letloose by science can be properly focused and wisely used. Accomplishingthese ends necessitates a major effort on the part of science and scientists-an effort dedicated to serving all of society and all of man. And whilefew can agree on the exact details, all concerned believe that science isindispensable for a future in which man is in reasonable harmony withhis physical and social environment.
Historically, the National Science Foundation has devoted a large pro-portion of its resources to the pursuit of disciplinary science-researchand science education motivated solely by the intrinsic needs of a disci-pline or the creative needs of individual scientists. This kind of program-ming has been highly successful and must continue, for it is the bedrockof all scientific enterprise. However, there must also be a heightenedawareness of the requirements placed on all science, and for this reasona significant share of the total resources available to NSF in the futuremust be devoted to the social and technological needs of the nation. This,however, does not mean that the Foundation should be diverted from itsearlier and historical purpose; in fact, this diversification should be con-strued as a means of strengthening that purpose.To ensure success, this additional objective must have the cooperation
of academic scientists, because a large number of the more creativescientists reside in academic institutions, and also because society andthe nation have great need of broadly trained scientists who are-highlymotivated and capable of pursuing careers associated with the publicinterest.To bring the best of science to bear on the social and technological
problems of society requires at least three steps. A larger number of themost creative members of the scientific community must be encouragedto associate themselves with the great problems of man and society; foreven though not all of the world's ills have a scientific or technologicalbase, the thought patterns of science and its intellectual-mnaterial accom-plishments are proof that science has much to offer society. The re-search and training institutions associated with creative science and themechanisms used to support science must be more clearly focused andreceptive to both the immediate and long-term interests of man andsociety. The National Science Foundation, as one of the most im-portant federal institutions to promote the progress of science, mustfocus a larger portion of its resources on all of science-not just onacademic science.The social milieu within which the NSF finds itself has changed so
markedly and so rapidly that we must not fail to accept the challengesoffered by these new and pressing opportunities. We should recognizethat, although science is one of the great cultural accomplishments ofman, public support on the scale required for man's survival can bejustified only as the needs of the larger society are reoognized.
-W. D. MCELROY, Director, National Science Foundation
On 1 February 1972, Dr. McElroy will become chancellor of the University of Californiaat San Diego.
