This paper argues that Hannah Arendt's political theory offers key insights into the power that binds together the feminist movement - the power of solidarity. Second-wave feminist notions of solidarity were grounded in notions of shared identity; in recent years, as such conceptions of shared identity have come under attack for being exclusionary and repressive, feminists have been urged to give up the idea of solidarity altogether. However, the choice between (repressive) identity and (fragmented) non-identity is a false opposition, and (...) the Arendtian account of solidarity developed here allows us to move beyond this opposition. Thus, Arendt provides us with a model of solidarity that can stand a post-identity politics feminist theory in good stead. (shrink)
