LotR -- Book 1 - Chapter 02 - The Shadow of the Past

[Fordim Hedgethistle]

Oh, but we can pursue the question here, but I don't think we're going to get anywhere. As I cited above (but will do so again here)

[Frodo] unfastened [the Ring] and handed it slowly to the wizard. It felt suddenly very heavy, as if either it or Frodo himself was in some way reluctant for Gandalf to touch it.

In this quote, I think we have both possibilities that you suggest davem put side by side and held in some kind of difficult and tense balance -- perhaps suspended is a better way of putting it. The text is uncertain about what's going on here: is the Ring reluctant (and thus 'in charge,' plunging us into a Manichean world of Good vs Evil, in which the individual will is merely the battleground upon which these large forces confront one another), or is Frodo reluctant (and thus still possessing his will, moving us into a world of good or evil choices)?

This ambiguity perhaps explains the ambiguity of this strangly split Frodo -- is a flawed person showing those flaws but able to overcome them, or is he a Good person being taken over by Evil? I think that these questions are introduced here, raised to a fever pitch as the novel progresses, but then never fully answered (which is a smart move on Tolkien's part, I would suggest. . .)
