The Greatest of the Eldar

[Feanaro]

"Furthermore, one can even argue that Fëanor had a weakness of spirit, when one considers his inability to deal with his anger, his rashness, cruelty, etc."

I would disagree entirely. I would say that Fëanor's spirit was perhaps too potent. Remember the meaning of his name: Spirit of Fire. All of these negative characteristics, I would argue, are not the product of having a weak spirit, but of an overly fiery one.

As for the rest of this topic, oblo did not throw a theory out into the fray. He answered a question by stating the author's opinion, which, when applied to his own works, is law. This is not to be contested. This topic should not have carried on for this long. If you don't agree with this, fine, but don't try to argue against the author's opinion (which is much more important than your own on such a subject).
