"The rise of modern natural sciences was based on the belief that knowledge about nature would increase steadily and that sooner or later it would prove useful for people and society. How these expectations shaped the self-image and the development of the natural sciences is the subject of this book. It turns out that expectations have repeatedly changed: from the universal ideal of utility of the 17th and 18th centuries to the promise of technical progress that is decisive today. The unshakable belief in the usefulness of the natural sciences has always been accompanied by the insight that progress in knowledge can only be guaranteed if research is not based solely on short-term needs. In her story of the modern understanding of science, Désirée Schauz draws a bow from early modern natural research to the natural sciences of the 20th century. With its long-term perspective and its conceptual historical instruments, this book not only makes an important contribution to the modern history of science, but also provides a historically sound basis for current debates on science and innovation policy."-- publisher's website.
