Historian Nicholas Goodrick-Clarke analyzed the topic in The Occult Roots of Nazism in which he argued there were in fact links between some ideals of Ariosophy and Nazi ideology. He also analyzed the problems of the numerous popular occult historiography books written on the topic. He sought to separate empiricism and sociology from the modern mythology of Nazi occultism that exists in many books which "have represented the Nazi phenomenon as the product of arcane and demonic influence".
