“The Indo-German identification” A book which entered the official NSDAP texts in anthropology and heredity, which tracks their indo-scythian ancestry back to India which had been believed to be the origins of humanity. They believed the Ahnenerbe would create a sense of unity between Germanic peoples if they knew their glorious ancestry. “National Socialism and race” by Anthony James Gregor It shows the writings of Hans Guenther, Karl Weinlaender and Hitler, it debunks the Nordic hypothesis of a “biological Aryan race” which Weinlaender and Guenther believed. While showing the metaphysical beliefs Hitler wrote about, i.e. a race based off things like Pathos, Ethos, Logos, (immaterial values) it explains how Hitler dismissed any Biological notion of race, and rather used what continental Europeans believed during the middle ages about race. “Positive Christianity in the third Reich” Haven't read this but it goes in depth on what Positive Christianity meant, most likely about the unification of all Christian denominations and the separation of the Church and the state, as they were recognized as two different realms. It goes hand in hand with point 24 of the 25 point party program. Also debunks any accusations that Germans were anti-christian when actually they were anti-clericals. “Fascist Economics and Socialism of duty” by Welwesberg Archive Points out that fascist economics are secondary and upholds all that the metaphysical world is above the temporal. I have to go so I cant explain this one as much. But basically it doesn’t necessarily talk about their economic program in depth, so if you want something like that go read Gottfried Feders manifesto, and speeches.
