  Other feminist critics note that liberalism continues to treat unproblematically many of the concepts that theorists in the 1990s and since have problematized, such as “woman” as a stable and identifiable category and the unity of the self underlying self-rule or autonomy. Critics (such as Zerilli 2009) have argued that the universal values that liberals such as Okin invoked were really expanded particulars, with liberal theorists mistaking their ethnocentrically derived values as universal ones. At the same time, however, some feminist critics are showing how many of the values of liberalism could be performatively reconstituted. (See section 2.7)
