 There are a couple of over-arching questions that are worth raising now with a (brief) overview in place. The outline offered here suggests that in a number of different ways feminists are keen to “unmask” or “uncover” or “demythologize” certain aspects of our ordinary (and philosophical) thinking. Where ordinarily we take ourselves to be dealing with an ontology of substances, natural things, intrinsic properties, we’re in fact dealing with an ontology of social things, relations, and non-substantive (and often normative) kinds. But what is the relationship between these sorts of “unmasking” projects and projects that count as part of “mainstream” philosophy, or more specifically, “mainstream” metaphysics? So much analytic metaphysics consists in “reconstructions” of our ordinary concepts; a significant amount of it is unabashedly “revisionary”. So along those lines, feminist metaphysics would seem to fit right in. Clearly feminist metaphysics differs from the mainstream in its subject matter and background assumptions, in particular in its focus on the possible value ladenness of our concepts, categories and theories, and its attention to the potential harms of justificatory ideologies. But are there more substantial differences? Is feminist metaphysics just “mainstream” metaphysics directed at different issues, or is there a deep difference? And if there is a deep difference, what exactly is it? Barnes and Mikkola have recently charged that certain prevalent conceptions of metaphysics in non-feminist circles even rule out feminist metaphysics. The charge is that prevalent conceptions of metaphysics in mainstream metaphysics take metaphysics to be concerned with the basic structure of reality and what is “fundamental”, where it is assumed that social reality cannot be fundamental or basic (Barnes 2014, forthcoming; Mikkola forthcoming). Jonathan Schaffer and Ted Sider have engaged with these charges (Schaffer forthcoming; Sider forthcoming), attempting to show that their respective metametaphysical theories allow room for feminist metaphysics and metaphysics of the social more generally.
