Abstract

Within French epistemology the question is central whether the present can be a reference point for the history of science or whether scientific practices should be understood within their own historical context. Both positions are linked with problems: either it results in a ‘whig history’ written from the perspective of the victors or it leads to the accusation of relativism and to resistance from the scientists themselves. Isabelle Stengers claims that this resistance by scientists must be considered as an essential element in the historiography of the sciences. She is part of a more recent generation of French philosophers of science, who build on the work of the earlier generation but with significant differences. Stengers interprets the scientist’s work as ‘in the service of history’: everyone must be forced to recognize their work not as the product of personal construction but as a necessary discovery in the history of science. The work of the historian of science is in conflict with the aims of the scientists themselves, who want to be seen as the norm of the present by which one should read the history of science. This service of history is not some external ideological factor, but an internal part of the scientific practice itself. The construction of the difference between the discovery of a pre-given fact and the construction of a fiction is for Stengers the core of the scientific practices. This use of history will be illustrated by the case of synthetic biology, as described by Bernadette Bensaude-Vincent. Synthetic biologists are invoking specific past or future scenario’s, such as that of synthetic chemistry or computer engineering, to legitimatize their current research projects and ambitions. From this perspective, the problematic tension between the past and the present is so hard to cope with because it is not merely a struggle among historians and philosophers of science, but also among the scientists themselves.
