Abstract

The purpose of this paper is to highlight an aspect of Elisabeth’s intellectual life that has received little scholarly attention so far, namely Elisabeth’s involvement with the sciences of her day. Firstly, this paper provides a survey of Elisabeth’s interest in and engagement with various scientific disciplines, such as mathematics, medicine, natural philosophy, and microscopy, drawing on her letter exchange with Descartes and several other intellectuals as well as additional documents, such as dedications of scientific works to Elisabeth. Secondly, this paper investigates Elisabeth’s involvement with one particular scientific discipline, namely astronomy. Analyzing Elisabeth’s letter exchange with Andreas Colvius and Constantijn Huygens and additional letters and testimonies, I show that Elisabeth played an active part in at least three current debates in astronomy, namely concerning the discoveries of the satellites of Jupiter, the emerging maps of the moon, and the invention of the new telescopes. Based on the evidence provided in this paper, it is argued that Elisabeth’s intellectual biography should be broadened. It is not sufficient to perceive her only as a critic of Descartes’ philosophy, as this characterization does not accommodate her scientific commitments, but rather as a multitalented intellectual.
