This NWO-funded research programme focuses on the assumptions and methodology of the writing of history of science. History of science is in many respects a flourishing discipline: it currently yields an impressive volume of studies. Systematic reflection about the ways in which history of science may…

Historiography of science is in its current self-image a non-evaluative discipline. Its main goal is to understand past processes of knowledge formation on their own terms. In the last few decades this approach has greatly improved our understanding of the phenomenon of science. Yet, something strange…

Nature and History, Towards a Hermeneutic Philospohy of Historiography of Science

ASLU 16

Is it possible to formulate a new conceptual foundation for attributing an evaluative role to historiography of science, without relinquishing the historiographic sensitivity of recent work in the discipline?

The aim of this project is to foster a historiography that does justice both to the realization that scientific knowledge is constructed by local, contingent, and contextual processes, and the claims of science to objective validity.

This project will construct an inventory of possible conceptions of the resistance of the world to scientists’ claims and theories.

In what way is constructivist logic able to account for both the role of the judging agent in inference and the universal claims of logical validity?

In 2022, Leiden is the European City of Science. This means a year full of attention to science, knowledge and art. And, of course, the Faculty of Social and Behavioural Sciences cannot be absent. Discover what our researchers have on offer during that year.

This book explores how physicists, astronomers, chemists, and historians in the late nineteenth and early twentieth centuries employed ‘epistemic virtues’ such as accuracy, objectivity, and intellectual courage. In doing so, it takes the first step in providing an integrated history of the sciences…

The demolition of the high-rise building is ready. The remaining debris are removed and the area is cleared. For the demolition, the University applied the BREEAM evaluation method at the level of ‘Excellent’, which means that the demolition operations were carbon neutral and did not cause any form…

In comparing a selection of 18th-century histories to a representative sample of 19th-century histories of science, this project inquires: Which early modern vices persisted into the 19th century and to what extent were those vices embodied in anecdotes, conveyed through commonplaces, or symbolically…

This project aims to situate the current policy concept of ‘valorization of scientific knowledge’ in historical and epistemological perspectives. Conceptual understanding of the utility of scientific practices is developed in dialogue with historical analyses of the politics of knowledge in European…
