Introduction: Mary Wollstonecraft (1759-1797) is established in the popular imagination as the “first feminist,” but another philosopher provided a systematic analysis of women’s subjugated condition and a call for female education nearly a century before Wollstonecraft’s A Vindication of the Rights of Woman (1792). Mary Astell’s (1666-1731) A Serious Proposal to the Ladies, for the Advancement of their True and Greatest Interest by a Lover of Her Sex, Parts I and II (1694, 1697) is a philosophical text that argues that women are in an inferior moral condition compared to men, analyses the causes of this problem, and presents a two-part remedy.
