No Abstractions Allowed

Postmodernists deny that abstractions are more than vicious fictions. Their radical, irrational, and skeptical epistemology is well known. 

But then they add abstraction and objective reality back into the mix by arguing that power is the ontological substrata of the world, and that this metaphysical reality must be accepted and honored. Now, the power of group versus group is the reality claim the neo-Marxists champion the dispossessed groups as their allies in this incessant, inevitable war.

One of the things that I like—in part--about postmodernists is that they deny that truth exists or that it is universal. Some skeptical keeps us epistemically humble, careful, and wary of totalistic claims. As a moderate I believe that truth exists and that it can be rationally, linguistically, scientifically known with near universal certainty.

Now, the postmodernists are liars and hypocrites epistemologically. They contradict themselves: epistemologically: they are skeptical relativists and they are ontological absolutists. They actually were absolutists all along, because the metaphysical absolutism is a cover for their epistemological absolutism--that Marxism is the one truth faith to be spread all over the world. They are now revealed as epistemological and ontological absolutists, true believers.

For a while, a few decades, they opined about epistemological relativism, but humans require values or they go mad. 

When the metanarratives of a people are hollowed out and discarded, the nihilists for a while, aver that no replacement metanarrative is possible, needed, required, or sought after.

Then what always happens is the people revolt: without a rational, sensible, human metanarrative or set of metanarratives, they will replace it with an ism, an abstraction, a word that they now worship and solely, enthusiastically support as the ultimate, the one panacea. That people would join a mass movement as true believers every time the culture collapses, if there is no replacement value system, is proof that people require metanarrative, an objective narrative, a universal account of how the world works. 

People biologically, religiously and ontologically require an account of objective reality, which is evidence that objective reality is out there, and the subject must always characterize the object and create meaning or go mad. The account may not be perfect or irrefutable, but it must be composed, distributed, and accepted as the cultural theme accepted by the majority of a people. This is one proof that there is an external world.

In their videos, Jordan Peterson and Stephen Hicks seem roughly to accept that there is an ontological substrata of power, but they urge that power be used for good not evil.
