You have understood nothing.
Neither statement can be true OR false. If statement A is true, statement B is true, which means statement A is false. To simplify, if statement A is true, statement A is false.
"This statement is false" can be neither true nor false. That is the most basic paradox there is.
My dude. The paradox doesn't change based on whether or not the judge knows the truth, or even if the man dies.
The truth is the man was made not to expect a thing by his own logic proving he would always expect a thing. The paradox is based on his own prediction being wrong because of his prediction. In this instance, his prediction was what his emotions would be.
A horse walks into a bar, and the barman says "why the long face?" I haven't said how they remove the horse from the bar, so does that mean I didn't tell a joke? Or does horse removal not actually matter to the joke?
