Al Iswell is arguing with his girlfriend, Ima Right. At one point, Al says, “That might be true for you, but its not true for me.”
Ima frowns. “huh?”
“Well, you know. What’s true for you is true for you, and what’s true for me is true for me.”
Confused, Ima says, “But I think that if it’s true, its true for *everyone*.”
Al shakes his head, ready to enlighten her. “That’s true for you…”
“Then its true for everybody” Ima interrupts. “What do you mean?”
“Well, I think that “true statements are true for everybody”. You just said that was a true statement, for me. If its a true statement, then its TRUE that its true for everybody. And if you don’t think it’s true for everybody, then what you’re saying is that I’m wrong. Which means that it’s NOT true for me. You can’t have it both ways. Do you see what I mean?”
“Another way you could put it:
1. Say person A believes “true statements are true for you”
Person B believes “true statements are true for everyone.” (all TS are true for all People)
2. According to Person A, person B’s belief is a true statement. Since “all TS are true for all people”, and since it is a true statement and A is a person, it is true for A. So it is true for A that “TS are true for all people”.
3. But Person A doesn’t like this. They say, person B is wrong. But this means that Person B’s belief is NOT true for them, so Person A doesn’t really believe that ‘if its true for you its true for you’. It just doesn’t work.
