As to your question: "Who overcomes the world?" It certainly isn't the Superman, who must end up being destroyed with it. 1 John 5 tells us all we need to know about this "overcoming the world" business. It tells us the only way we can do that.
Good stuff. Really, thank you again. Ayn Rand and Orwell explained the left/totalitarian motivation as the will to power . . . but I was never satisfied with that because of the reality denying nature of their thought. The leftist totalitarian has to live in the nightmare they create as well, even if they are partially in charge of the nightmare. Voegelin’s explanation of it as a psychological phenomenon . . . a turning away from reality that requires others to accept the illusion as well to avoid facing reality rings true to me at a deeper level than just the desire for power. Probably different mixes of the three motivations exist person by person who promote a totalitarian or God denying agenda: protecting a denial of reality, the will to power, and a malignant desire to afflict others with your pain and problems (invitation of them into your hell).
