That sciences are guided by explicit and implicit ties to their surrounding social world is t new. Jaan Valsiner fills in the wide background of scholarship on the history of science, the recent focus on social studies of sciences, and the cultural and cognitive analyses of kwledge making. The theoretical scheme that he uses to explain the phemena of social guidance of science comes from his thinking about processes of development in general--his theory of bounded indeterminacy--and on the relations of human beings with their culturally organized environments. Valsiner examines reasons for the slow and nlinear progress of ideas in psychology as a science at the border of natural and social sciences. Why is that intellectual progress occurs in different countries at different times? Most responses are self-serving blinders for presenting science as a given rather than understanding it as a deeply human experience. For Valsiner, scientific kwledge is cultural at its core. Major changes have occurred in contemporary sciences--collective authorship, fragmentation of kwledge into small, quickly published (and equally quickly retractable) journal articles, and the counting of numbers of such articles by institutions as if that is a measure of scientific productivity. Scientists are inherently ambivalent about the benefit of these changes for the actual development of kwledge. There is a gradual takeover of the domain of scientific kwledge creation by other social institutions with vested interests in defending and promoting kwledge that serves their social interests. Sciences are entering into a new form of social servitude.
