In their new video, "Is Community A Postmodern Masterpice?" Mike (the host) opens up by explaining what postmodernism is. I mean, not really. That's not how postmodernism works. But he does a pretty good job of covering the major reasons it's not easy to explain, and leads into the general idea enough that viewers might be able to distinguish postmodernism from other philosophical perspectives. It starts at the 1:00 mark, with the perfect introduction, "What is postmodernism? I'll give the philosophy and art history students a moment to finish their collective 'Ugh.'"
I'm posting this because I will be referring back to it regularly in otherwise usually frustrating conversations with my extended family.
