A synoptic overview of a bunch of quite different strains in philosophy that all in various ways share the name "materialism". It explicitly doesn't pay much attention to the kind of materialism I am familiar with, the scientific naturalism of Dennett, cognitive science, and general tech-atheist-rationalist discourse. It's focused more on people like Marx, Nietzsche, and the various ways they have thought about the body and the corporeal nature of thought and existence.
The problem is that you just can't throw out fundamental cultural dualities like that. They are too strong, too connected to how we think. You discard the supernatural, and people think you are throwing away morality, awareness, love, sacredness, and everything else that is traditionally connected to the divine. And they may be right!
This is one reason I am spending my free time hanging out with intelligent supernaturalists and trying to be part of their club.
