ABSTRACT
This chapter offers some arguments in favour of the claim that science can be viewes, in some respects, as a single whole. It concerns the application of what has been said about practice to the case of science, so as to identify the sense in which one can legitimately speak of scientific practice in the singular. The chapter concentrates on two problems. The first one will concern how to understand the fact that protagonists of scientific activity seem to have different purposes. The second, which will demand a much longer treatment, will concern how to understand the fact that protagonists of scientific activity seem to have a purpose that is simply too general to be relevant. The chapter involves the application of what had been said about discourse to the case of science. It explores experimentation wherein both scientific practice and discourse are at work.
