As I told you before, I would love to share with you some thoughts on the cultural links between Tolkien and the European New Right (ENR). Perhaps, these thoughts are not new and eventually commonplace for you, but even if it is so, maybe you can clarify some points.
I agree with you completely that the notion of mythical time expressed in Tolkien’s works was and still is the major reason of the adoption of his ideas by the ENR. Of course, the nostalgia, as you write, for "a total world view [and] a holistic understanding of existence, warm and 'alive'" is crucial to the ENR. In Tolkien’s works one can also find references to the four Yugas, which are important to the ENR influenced by Integral Traditionalism of René Guénon and some others: "the Ainulindale", "the Years of the Lamps", "the Years of the Trees" and "the Years of the Sun". However, I believe that Tolkien’s racism is also important for the ENR.
