[Gwathagor]

Proof? Faith is an island in the setting sun, but proof is the bottom line for everyone...no, wait, that's Paul Simon...

I don't really have any textual proof; I've basically made a philosophical argument based on inference. I personally think the line about wise men watching the stars is pretty clear, but I'll see if I can't dig up something more substantial. Something in the letters, or the HoMe, or the Unfinished Tales.

Cheers.
