Evola's racism included racism of the body, soul, and spirit, giving primacy to the latter factor, writing that "races only declined when their spirit failed." For his spiritual interpretation of different racial psychologies, Evola was influenced by the German race theorist Ludwig Ferdinand Clauss. Like Evola, Clauss believed that physical race and spiritual race could diverge as a consequence of miscegenation. Peter Staudenmaier notes that many other racists of the time found Evola's "spiritual racism" perplexing.
