Interesting - I would agree that either you're a materialist or you're not, and that either you think the world is made up of entirely psychical matter or you don't. In that sense, it is MMs against DDs/AAs. But there is something which unites MMs and DDs against AAs, namely the denial or repudiation of one aspect of our subjective life that is immediately observable to every person. The materialist is in the trap of has to somehow account for everything rich and lively and interesting about human life - consciousness, poetry, art, love, mysticism, feeling, thought, free will. I don't think materialism, to use your language, provide any explanatory value for these things we all know so well. The DD has the equal and opposite problem - it's busy trying to shake off the material world and the body. AAs, I will grant, have problems - but it is not a lack of accounting for things. If anything, it is accounting for them too well, and having to do some leg work to show exactly how this conception of soul differs from Descartes and Plato's dualism and brings it "to earth." For that I would turn to Aristotle's "De Anima" and Aquinas' "Summa".
