A Logic Accusation (Posted on 2003-10-01)

In an island peopled by Knights (who always say the truth) and Liars (who obviously always lie), two persons spoke about each other.

A said: "B would say I lie."

B said: "That is true."

Can anything be deduced as to what kind is each of them?

aaahhhh... I see what you're saying.

I don't think that's what was meant (referring to the particular instance of this statement). But I agree... there is an ambiguity in the meaning.
