2 things are required for post modernism. Matter replication and the low/zero cost energy to drive it. Once food and objects require little to no resources, the only way humanity can progress is into the realm of pure innovation and creativity. The post modern progressives think like this however....

They have no recourse for energy, economics, and curiosity. They expect to remove by force instead of by innovation. The force breeds resistance in general.

Basically the author "nailed it" w/this final quote from his article: ". . . Much of what we see being advanced under the banner of 'postmodernism' is simply hypocrisy in disguise."
I've pointed out for years that the claim of, "There is no such thing as absolute truth." is stupid on it's face - this claim itself would be a self-declaring "truth" statement. So let's stop the BS & REALLY have an intellectually HONEST discussion. . .

I'm learning about postmodernism myself and came across this article written by Michael Shermer in 2017:

[scientificamerican.com]

Shermer pointed out: "Students are being taught by these postmodern professors that there is no truth, that science and empirical facts are tools of oppression by the white patriarchy, and that nearly everyone in America is racist and bigoted, including their own professors, most of whom are liberals or progressives devoted to fighting these social ills." Scary right?

Then he concluded: "If you teach students to be warriors against all power asymmetries, don't be surprised when they turn on their professors and administrators. This is what happens when you separate facts from values, empiricism from morality, science from the humanities."

Will the leftist eat themselves soon enough?

The best book (in terms of clarity) on this subject is Stephen R. C. Hicks
Explaining Postmodernism: Skepticism and Socialism from Rousseau to Foucault (2011)

We perceive the world through our own senses that are vulnerable to distortion however a truth should be a repeatable finding . Post modernism as I understand it believes everything is a social construct all around us nothing is inherent and it is the social influencers that determiner us not innate character this I do not agree with I believe there is some social constructive elements but match is inherent in our genes as demonstrated by using the same experiments on human children as other primates and having the same results full stop for example monkeys giving toys to play with Will divide on the same gender lines as humans with female monkeys interested in toy babies. Another example is of monkeys giving tokens to exchange for chocolate soon trade those tokens for sexual favours from female monkeys who then consume the chocolate the oldest profession!!!

Postmodernism is essentially the idea that "truth" is subjective, and thus the product of the individual's own feelings or perspective. Postmodernism declares that if an individual believes something, or otherwise feels some form of reality is true, then it must be true [to that individual]. The danger in this line of thinking is that logic, reason (practical Aristotelian reasoning), and truth lose an objective quality. This is why I do not agree with the phrase "one's own/personal truth." Truth is truth. It is objective and it exists independent of one's choice to accept it or not. Postmodernism is a direct attack on objective truth, and, more specifically, on objective reality.

Can't say I put much credence in postmodernist philosophy, suffice to say I do believe each individual given enough time will arrive to their truths in life, and question things accordingly.

And look up Nick Land’s work called Machinic desire and Deleuze’s concept of deterritoriallization.
