Excerpt from Symposium on Human Problems in the Utilization of Fallout Shelters: Held at the National Academy of Sciences, Washington, D. C., 11 and 12 February, 1960 Changes in culture occasioned by the introduction of innova tions have sometimes posed extremely complex and challenging problems for planners and administrators. The difficulty, as stu dents of society have known for many years, stems partly from the fact that material and non-material components of a culture are necessarily interrelated and their relationships are conditioned by a complex of basic values. More importantly, the student knows that a satisfactory integration of the new material component does not proceed automatically. Nor does the most lucid and authoritative presentation of all pertinent facts necessarily ensure a prompt or satisfactory adoption of a new element. Changes in basic material culture may require the most sophisticated planning considerations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
