The reflection on science seems to be linked today with the concept of hypermodernity which refers to a society of excesses without any global alternative model. In this article, my aim is to show how the modernisation of our societies was connected with scientific development, and what place science may be expected to occupy in hypermodern societies—societies built around the notion of risk. After presenting the concept of hypermodernity, I propose an analysis of the inherent risks involved by the development of technology in our societies, and what limits may be desirable in order to prevent an excessive or partial valorisation of a "society of knowledge," a notion itself not without its problems. Finally, I remind of the possible contribution humanities and social sciences can make to maintain balance in what is today called a knowledge economy.
