In The New Politics of Science, David Dickson points out that 'the scientific community has its own internal power structures, its elites, its hierarchies, its ideologies, its sanctioned norms of social behavior, and its dissenting groups. And the more that science, as a social practice, forms an integral part of the economic structures of the society in which it is embedded, the more the boundaries and differences between the two dissolve. Groups inside the scientific community-and vice versa-to achieve their own political ends.' In this edition, Dickson has included a new preface commenting on the continuing and increasing influence of industrial and defense interests on American scientific research in the 1980s.
