I think he touched on some stuff that's still relevant today. You have that idea of the Ubermensch:
Nietzsche introduces the concept of the Übermensch in contrast to the other-worldliness of Christianity: Zarathustra proclaims the Übermensch to be the meaning of the earth and admonishes his audience to ignore those who promise other-worldly hopes in order to draw them away from the earth.[3][4] The turn away from the earth is prompted, he says, by a dissatisfaction with life, a dissatisfaction that causes one to create another world in which those who made one unhappy in this life are tormented. The Übermensch is not driven into other worlds away from this one.
I posted on that
just last night, I was saying that there are those who embrace a cold and analytical view of this world to gain power from it, and in so doing forsake ideals and religious concepts, and that furthermore this is leading to a bifurcation of the culture into a small group of extreme elites vs. believers. I said the left is in kind of an uncomfortable place in between, most not embracing hardcore dogma, but still holding to a priori moral ideas like the very religious.
So yeah, its all as fresh and as real as it was back then. And I totally understanding looking at that choice between amoral embrace of the world and faith, and choosing faith. I understand it completely.
