Instead of power, what about competence, beauty, skill, talent? It's self-contradicting, because it gives you no direction for action. Questions everything. Reading literature through a postmodern lens, who is the group being represented. Takes the thing and strips all meaning from it. To destroy all system of beliefs. To even ask the question of what the meaning of life is postmodern, it's postmodern to think of the future. Borderlines nihilism. You can't be for or against anything. It exhausts all theories and values. Such that you have no ground to stand on. If you take deconstructionism to it's very end, it boils down to power, pitting the oppressor against the oppressed.
