 Metaphysics is the study of the basic structure of reality, of what there is and what it is like. It considers, for example, concepts such as identity, causation, substance, and kind, that seem to be presupposed by any form of inquiry; and it attempts to determine what there is at the most general level. For example, are there minds in addition to bodies? Do things persist through change? Is there freewill or is all action determined by prior events? But since metaphysics not only concerns itself with what there is (ontology), but also the nature of that which exists, metaphysicians ask, for example, whether numbers, if they exist, are dependent upon human thought and practices in some way, whether the concepts and categories we use to think of and describe reality influence or determine in any way what is described, and whether and how values are embodied in our categories and descriptions. It should thus not come as a surprise that there could be a specifically feminist metaphysics, where the question of prime importance is to what extent the central concepts and categories of metaphysics, in terms of which we make sense of our reality, could be value laden in ways that are particularly gendered.
