A Logic Accusation (Posted on 2003-10-01) Difficulty: 2 of 5
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?

Solution This should be in Liars and Knights. Comment 17 of 17 |
B agrees with A, so B would not say that A lies. Therefore, A is a liar. Since B agrees with A, B is also a liar. They are both liars.
