It is hard to believe that it was only in 1986 that the first two modern books on Mary Astell were published, one a biography, the other a collection of complete and excerpted works. In the 30 years since, all of Astell’s major writings have been made available, several with substantive introductions, and three monographs, an anthology of critical essays, and dozens of academic articles from multiple disciplines have been published. We can now add to the growing list this book by Jacqueline Broad, who has mastered and engages with all of this primary and secondary literature. Broad is the first to read Astell’s texts as parts of “a united and consistent” (5) philosophical system with a moral theory at its core, which she importantly claims is how Astell understood her own work. Broad’s unmistakable grasp of Astell does not always manifest itself evenly; one chapter tackles a particular work while another deals with a theme and yet another makes central a conflict in the secondary literature. Further, one chapter is overwhelmed by comparisons with those who influenced Astell, in another they rarely appear, and in none but the conclusion are contemporary links pursued, though they practically beg to be explored. Nonetheless, everyone will learn from this text, several debates about Astell are resolved in it, and Astell’s philosophical status is generally elevated.
