It seems to me that nothing would be more foolish than to re-establish the worship of Wotan. Our old mythology ceased to be viable when Christianity implanted itself. Nothing dies unless it is moribund.
The teachings of the Bible are so interwoven and entwined with our whole civic and social life that it would be literally impossible for us to figure to ourselves what that life would be if these teachings were removed.
If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrariwise, what it is, it wouldn't be. And what it wouldn't be it would. You see?
To consider this desirable would be to delight in the slaughter of men; and he who delights in the slaughter of men cannot get his will in the kingdom.
Without birth and death, and without the perpetual transmutation of all the forms of life, the world would be static, rhythm-less, undancing, mummified.
I don't really know what the dream role would be. That's a hard question to answer. You never really know, until you're immersed into something, how passionate you feel for it and how it unravels.
