The problem of unequal power in a discourse can be, and should be, separated from the intellectual product. A system of ideas, like Hegel's perhaps, might try to preempt all criticism from within its principles, but only a reader adrift and disoriented would accept the validity of such preemption at face value. A better approach is to examine the fundamental assumptions and presumptions of any system of ideas. The mapping from universally true principles of Generative Realism to ordinary everydayness allows for almost unlimited freedom to be, to choose, to think, to decide. Generative Realism is a realism, and assumes that something exists beyond the conceptual, thinking, choosing Social Self which constrains it.
Any realism is therefore just a power play.
But according to Generative Realism, it is not possible to be free of all facts. Even the freedom from facts that postmodernists claim is constrained by the postmodernists' embodiment, individuality, and intersubjectivity which make language and culture possible. If postmodernists were taken at face value, we would ignore them because they cannot speak to us, by their own standards. Another postmodernists complaint is that any system of ideas can only be a product of the culture in which it was produced, at a particular moment in historical time. Since everybody lives only in one moment of history and in one culture among many, there can be, in principle, no theory that applies universally to human beings.
