“All ballplayers are liars.”
Consider this statement for a moment. A paradox. If a ballplayer were to announce it, we would share in the contradiction. Because if a ballplayer declares all his brethren to be lairs, then he in fact is calling himself a lair and in that sense, how can we ever believe what he is saying? String that logic together, you have to ascertain that in order for the paradox to exist, a statement which forms the basis must be true. We now, through one line, have witnessed a self-referential paradox.
It seems like something Pete Rose would have said off the cuff to a reporter.
