With apologies to those who hate reading stuff on LOTR (so why did you open this one, anyway?:)), I just realized this morning that there’s a sort of open question, at least in my reading of Tolkien, on the choices those of Elf-human ancestry were to make to be of one “kind” or the other:
Luthien, Elf on her father’s side and Maia on her mother’s, chose to become a human being in order to be with Beren whatever betided. By a special grace, this was granted her.
Tuor, husband of Idril Celebrindal, by a similar special grace, was permitted to be joined to the Eldar, though human, and to go to the West.
Earendel, son of Tuor and Idril, and Elwing, granddaughter of Luthien and Beren, ended up transformed mythically into the Morning Star and a sea bird. (No wonder Elrond has issues; imagine living 7,000 years knowing that that’s what’d happened to your parents when you were little! :))
After various violent deaths, their descendants of all of these eventually dwindled to Elrond and Elros, the “Halfelven,” who were given the irrevocable choice of to which kindred they would belong. We are told that Elros chose to be human, was granted a lifespan of 500 years, and became the first King of Numenor – and, eventually, the ancestor of Aragorn. Elrond, on the other hand, chose to be of elvenkind, married Celeborn and Galadriel’s daughter Celebrindal, and had three kids.
Okay, there is no question in canonical Tolkien but that Vardamir Nolimon and all the heirs of Elros are considered human and nothing but. The trace of elf-blood that remains ennobles them but apparently has no effect.
But the three children of Elrond are given the same choice as he and his brother had – though they can “delay the choice” – and the books leave Arwen choosing to be of humankind out of love for Aragorn, and the brothers continuing not to make a final choice.
There appears to be a contradiction here – you can, apparently, opt out of Elfdom but not out of Humanness. That doesn’t sound like it fits the philosophical underpinnings of the Tolkien universe. Any Tolkien geeks who care to explain what’s going on?
