More knights,liars,and knaves (Posted on 2003-07-07)

Knights always tell the truth,liars always lie,and knaves alternate between truths and lies.

Two people named Jimmy and Johnny make the following claims.

Jimmy:I am a knave.
Johnny:Jimmy is not a knight.
Jimmy:Johnny is a knave.
Johnny:Jimmy is a knave.

What are each?

It is most logical to say that Johnny is telling the truth, therefore he is a knight. He says that Jimmy is not a knight and that Jimmy is a knave.
Jimmy says that he is a knave (the truth) and that Johnny is a knave (lie). Therefore, Jimmy is a knave.
