liar paradox
     
         a sentence which asserts its own falsity,
        e.g. "this sentence is false" or "i am lying".  these
        paradoxical assertions are meaningless in the sense that there
        is nothing in the world which could serve to either support or
        refute them.  philosophers, of course, have a great deal more
        to say on the subject.
