Wow, what a great article (almost)!

As a postmodern philosopher, I can say that Mr. McKnight's article about "truth" in postmodern thought is very accurate- but he isn't telling the whole truth. 

In postmodernism, Truth breaks down into categorizes, or as I like to call them - narratives. For example, you have truth that takes the shape of collective narratives like science, where truth is rooted in things like the periodic table and the laws of physics. This Mr. McKnight forgets to mention. 

What he does, is conflates narratives. He conflates a political narrative with another narrative, individual truth. Today, I will agree with Mr. McKnight that there is no truth in the political narrative. But that is because ideology obscures truth. Four main ideologies and their methodologies socialism, liberalism, conservatism and capitalism prevent a political truth from existing.

As for you who read this, you know that truth exists, because you know what you believe as true.
