 The concept of power is central to a wide variety of debates in feminist philosophy. Indeed, the very centrality of this concept to feminist theorizing creates difficulties in writing an entry such as this one: since the concept of power is operative on one way or another in almost all work in feminist theory, it is extremely difficult to place limits on the relevant sources. Throughout, I have emphasized those texts and debates in which the concept of power is a central theme, even if sometimes an implicit one. I have also prioritized those authors and texts that have been most influential within feminist philosophy, as opposed to the wider terrain of feminist theory or gender studies, though I acknowledge that this distinction is difficult to maintain and perhaps not always terribly useful. Debatable as such framing choices may be, they do offer some much needed help in delimiting the range of relevant sources and providing focus and structure to the discussion.
