Scholars have long recognised that Mary Astell builds her feminist critique of society on a foundation of Cartesian views about human nature and the passions. At the same time, the full extent of the influence of Descartes’ view of embodiment on the solution Astell proposes in her Serious Proposal to the Ladies is only beginning to come to light. In this paper, I contribute to this ongoing project by arguing that Astell builds on Descartes’ ideas by addressing a blind spot (...) in his view, namely, that that the embodied self is socially situated, and that therefore, our social context plays a crucial formative role in the development of our passions. In doing so, I show Astell extends Cartesian philosophy beyond an egalitarian feminist critique of society, but also to a positive political theory offering a solution to the problems she identifies. Thusly, Astell shows the political potential of Cartesian philosophy as a framework for social critique and to seek solutions to the problems such a critique can bring out. (shrink)
