There is a great variety of feminist theories. Each one of them explains the achievement of women rights in a different way. Feminism theories emerged according to the necessities and conflict of interests of the period in which they were created. For this reason, much of them may appear in the first moment to be innovative, to be going against certain power structure imposed upon woman`s body. Nevertheless, when those theories are analyzed through the lens of the constituent power perspective used by Antonio Negri, the liberation perspective does not hold itself. In fact, they seem to be the result of an opposite effort towards the revolutionary process, an effort of the constituted power to break the liberation of women. In this sense, Judith Butler makes important criticisms to the frequently-used categories by the feminism movement and other minority movements. According to her, the struggle strategies used by minority movements lead the feminist movement to utilize the same apparatus of power that create unequal conditions for women, instead of supporting feminism expansion. One of the resources used is the appeal to identity, which excludes several categories of the movement and is essential to the elaboration of the Other concept. The criticisms to this traditional strategy as well as the theory founded by Butler help to enlighten a new way to retake the liberation process of women.
