Well, obviously I can read what the quote is, but I'm not sure where it's from...

It appears the quote itself isn't the problem; it's identifying the speaker. Here's a hint.
It was said by a wise person, directed to one who had just done a dangerously foolish thing.
Coincidentally, I just posted in a thread in The Books in the last day or two which touched upon the chapter from which this one was taken.

No, the burned hand teaches best. After that advice about fire goes to the heart.

Another Gandalf, that purveyor of fine quotes, in response to Pippin's saying that now that he's been harrowed by looking Sauron in the eye (so to speak) through the Palantir, even if all the stones were before him he'd sit on his hands. Or something to that effect.

We have a winner!

Go ahead, Mnemosyne.

Let's try this one on for size.

"- - - / - - - - / - - / - - / - - - - - - - / - - / - - / - - - / - - / - - - - -."

L, please.

Are there any O's ?

LO! O no, there are no L's. What the L?

4 gaping O's for you, though.

"- - - / - - - - / o - / - - / - - o - - - - / - - / - - / o - - / - o / - - - - -."

Hmm. What about S, then?

SO, no L

"- - - / - - - - / o - / - - / - - o - - - - / - s / - - / o - - / - o / s - - - -."

R please

'Fraid not.

SO, no liquids (l or r).

"- - - / - - - - / o - / - - / - - o - - - - / - s / - - / o - - / - o / s - - - -."

Let's have E, then.

Copout. ;)

S, O, E; no liquids (does that make this quote solid?)

"- - e / - - - e / o - / - - / - - o - - - - / - s / - - / o - - / - o / s - e - -."

T please.

TOES; no liquids.

"T - e / t - - e / o - / - - / t - o - - - t / - s / - - / o - - / t o / s - e - -."

King Dáin II's answer to the Messenger of Mordor.

And we have a winner!

Take it away, Inziladun.

Thanks, Mnemosyne.
