Over time, the selfsame ideologies become “hegemonic,” not because they change, but because circumstances change while the ideology becomes more and more concerned with its own preservation. What causes this decline into reification and stasis is precisely the absence of reflexiveness within ideological thought, the inability to recognize its own origins and limitations, and the lack of opportunities for thinking differently. In the sense we are discussing it here, criticality is the opposite of the hegemonic.
