Postmodernism and “post-truth”
The point of postmodernism is not and was never “there are no facts”, the denial of an objective reality. The point is that facts are unevenly distributed across a metamedium which distributes half-facts and falsehoods with equal facility. The point is that the whole-truth-and-nothing-but-the-truth objective reality is by definition inaccessible to the subjective experience of individuals; there is far too much to know for any one individual to know it all. The point is that he who controls the distribution of stories controls the stories themselves.
