This is just a theory. I was considering this.
What if, perhaps in the Rightist ruling party's infatuation with Communism and the Left (coming from Europe's revolutions, I suppose…) people in those days developed these possibly false spiritual ideas such as 'Hermetic mentalism' and "thought-form based spirituality".
See, to contrast Marx's idea that human consciousness is driven by materialism….many of those in the right…perhaps the ruling party or the academics clung to these anti-Marx ideas that human consciousness is driven by ideas, rather than materialism. Chiefly, the ideas of those in position of power and many on the Right are wealthy or influential.
It's like, in the same way people idolize the Bible and turn the Bible into idolatry (this is a sure fact, IMHO), perhaps these Right-leaning academics in those days turned those post-Hegelian concepts and ideologies into idolatry seeing as they were driven by this anti-Marx notion that human consciousness is driven by ideas.
This theory of mine is kinda off the wall, and I don't think it is credible because there is so much involved we're talking about here and so many people and so many ideas and so much time between the days of Marx and today.
