Once we reject the view that claims that no political position can rest on performative contradiction, and allow the performative function as a claim and an act whose effects unfold in time, then we can actually entertain the opposite thesis, namely, that there can be no radical politics of change without performative contradiction. To exercise a freedom and to assert an equality precisely in relation to an authority that would preclude both is to show how freedom and equality can and must move beyond their positive articulations. The contradiction must be relied upon, exposed, and worked on to move toward something new. There seems to be no other way. I think we can understand it as a mobilization of discourse with some degree of freedom without legal legitimation on the basis of which demands for both equality and freedom are made.
