The clarity and stability of these divisions of modernity are now being challenged in many ways. Some of these challenges come from modern technology itself. Another challenge to the modern divisions comes from studies of science and technology. Historical studies show that these divisions have not existed since time immemorial. Thus the results of science are not only the construction of rational technology and objective nature.
Politicians rely heavily on experts when risks, environmental or technological, are at stake.
Some argue that in practice, the most important desisions when it comes to risks are settled by those who describe them scientifically. Everyday life, practice and culture are part of what makes science, and science is producing everyday life. It produces nature as well as technology. So nature is part of our moral, of social order. Thus nature is culture.
