Do the Ringwraiths feel pain?

Yes, but Mirkgirl, this is a setting where spirits in general definitely seem to feel emotion, so that hardly applies. Besides, you might as well ask, "how could they think, without brains?"

Look, in principle I deplore the all-purpose "it's magic" excuse some fans use– but in practice I think there is a limit to how much you can cast a supernatural story in terms of our real-world knowledge of science. You certainly can't use a totally materialist world-view, at any rate, since that won't allow for the existence of spirits at all.

See? Fear is an emotion. And how do you know what the rules of, er, "not-flesh" are?

–Anyway there's another aspect to all this, too:

So physical is imho not a proper way to address anything that has to do with them.

Here's a continuation of the quote given by Zil:

Merry's sword had stabbed him from behind, shearing through the black mantle, and passing up beneath the hauberk had pierced the sinew behind his mighty knee

.
The Battle of the Pelennor Fields.

Which doesn't really sound "metaphorical" to me at all. I'm not sure what a knee could be a metaphor of, are you?

This has all been discussed here before, of course... but I think the idea is that they're not fully immaterial spirits, but rather have a sort of half-life in the "wraith-world". The question of how "real" their bodies are is left ambiguous, though.
