The Journal of the American Philosophical Association will be running a number of special series, each unified by a given theme designed to introduce readers to a field of philosophy with which they may not be familiar. The editorial conceit is to commission specialists to take a somewhat free hand in writing in an area they are passionate about, but in a way that is accessible to a new audience. In this issue, we kick off our Special Series in Women in the History of Philosophy with a paper by Jessica Gordon-Roth that addresses scholarly disagreement over the nature of the monistic ontology of Anne Finch Conway (1631–1679). Future issues will continue the series on an occasional basis, featuring papers on contributions to Western Philosophy by women from various periods of its history.
