Please stop shouting; it hurts my ears. By the way, I've been thinking of the so-called "liar's paradox." You know the one where the Cretan [the man from Crete] states: "All Cretans are liars." If the man is telling the truth, then the statement is false. But if the man is lying, then the statement is true. So, if the statement is true, it's false. And if the statement is false, it's true. I think it was Bertrand Russel who claimed that if a person thought about such paradoxes for enough time, he or she would be driven to insanity.
Another paradox is as follows -
1. The following sentence is true.
2.) The preceding sentence is false.
One way to escape the paradox is to state that, given the fact that the two sentences refer to nothing but each other, they merely constitute a self-referential, verbal "hall of mirrors" - a kind of endless "tape loop." Since neither sentence refers to anything outside of the other sentence, neither sentence has any real meaning at all.
