    Help Prove/Disprove Paradox

    Hi, I'm completely stuck on this hw problem. It's the last one, and I'm completely.... lost. Any help would be much appreciated

    Prove or disprove: There exists a book that refers to all those books and only those books that do not refer to themselves


    Thanks!

    One does not prove or disprove a paradox.
    A paradox has these properties.
    If A is a paradox then A being true implies that A is false.
    As well as, A being false implies that A is true.

    If R(A,B) on the set of books means that A refers to B if and only if B does not refer to B then does A refer to itself?
