Despite its length and sometimes overwrought writing style, this article does not quite manage to "explain" postmodernism, so much as caricature its worst manifestations and developments. We're all aware that these developments exist, but treating them as if they were the only product of the aforementioned 'French intellectuals' that might be worthy of notice strikes me as quite counterproductive! To take just one example from the beginning, the article claims that Nietzsche and Heidegger espoused "anti-realism and[] rejection of the concept of the unified and coherent individual"... I mean, really? Says who? (Is the author even aware that Heidegger lived in a hut in the woods most of his life? Does he think that this should tell us nothing about what he was actually trying to say, if not always with the greatest clarity?) And that's just the first issue I spotted here - to take another, if you think postmodernism can be described as "decidedly left wing", you're clearly unfamiliar with the rather nuanced stances of many of its proponents.
