Post-modernism isn't so much, there isn't any truth: more that there isn't any singular truth, as in, it's relative to perspective. This doesn't preclude outright lying, though - expounding false facts seems to be a move towards totalitarianism. I'm looking forward to a 21st review of the last 4 years by one of our bright philosopher/theorists and how it compares to the totalitarianism of the early 20th century.
