It's a question worth asking: do we, the new pagans, have a right to the ways and the lore of the old pagans?
To this, I would say: we do. They're ours by eldright.
David Cowley, who coined the term, defines eldright as “ancient right, tradition.” It comes to us by virtue of who we are.
We are the pagans, the True people. (It's an anthropological truism that practically every tribal name means the People, the Real People.) The contrary of this True is not false; the contrary of this True is unTrue. We are the ones who remain faithful (“true”) to the ways of the ancestors. Some have chosen other ways, as is their right. But in doing so they have thereby become unfaithful—untrue—to the ancestors and to their ways. Every people that remains True to its ancestral ways is a True people.
