Abstract

What is theHistorical epistemologyhistorical epistemologyGayon, JeanOn historical epistemology of the life sciences? In what way does it differ from historico-philosophical reflection on “foundational” or “conceptual” issues in the sciences tout court?

In this essay I reflect on how to conduct historical epistemologiesHistorical epistemology of the life sciences, focusing on two interrelated cases I have worked on in the past: vitalismVitalism (history of) and the constitution of biology.
