What power is Elrond referring to?

[Ainaserkewen]

Didn't Elrond also have foresight.

I never got that in the movie. What does "foresight" really mean anyway? I mean, I know it means you can see the future and what not, but why? And how? Elrond in particular. As far as I remember, I think a thread here came to the conclution that he was just really smart and could put together the puzzle pieces better because of his age and wisdom. There was obviously some magic involved here, but I doubt it was Elrond's...but I may be wrong because of whatever "powers" being a keeper of one of the Elvish rings brings you. Perhaps that's to be considered.

You know, I love these speculation threads...in a way, they're like thought experiments with no real evidence from the text, only ideas from the readers.
