From my own view, the problem is with the conceptual limitations of the dualistic categories of dialectical mind. For 2000 years, dialectical reasoning has grown in sophistication by creating synthetic (or transcendent or meta-) narratives to reconcile contraries. Postmodernism comes along and points out that meta-narratives aren’t really doing the work that we supposed them to do. They don’t really solve the dichotomies, they basically take one of three ways out 1) reduce them to conceptually more foundational dichotomies — such that, for example, you have the ultimate contrasts in Buddhism “emptiness” and “form” and two truths doctrine (relative and absolute) , Schopenhauer gives us “world” and “representation” for Derrida we have “sameness” and “difference” or the ultimate contrast in Hegel “matter” and “spirit” or in Bhaskar “absence” and “identity” …. or 2) hold paradoxes simultaneously– as “two sides of the same coin” — this is Wilber’s tetra-emergence, or Heidegger’s paradoxical thinking, and also Nishida Kitaro’s answer to Hegel, or 3) establish a meta-theoretical framework upon which the endless synthetic narratives can be adjudicated — hence Integral theory is a meta-theory which contextualizes ‘green’ narratives as “higher” than “blue” narratives — the problem is, a different meta-theoretical framework such as Critical Realism can, through explanatory critique, counter the Integral meta- framework, and so one is left with the frustrating position of having to formulate a meta-meta framework to contextualize the meta-theoretical frameworks. It is easy to show that this pushes the situation of “grand narratives” up a notch in terms of conceptual sophistication, but it does not solve the problem of grand narratives and as such is still subject to the post-modern critique (IMO).
