How about if X is a set of assertions that logical tautologies are true:

An example along similar lines to this post would be: you can't be wrong about thinking you are thinking about X - if you are thinking about X.

P v -p is disputed, so someone is wrong there. Also, if you have ever done a 10+ line proof or 10+ place truth table you know it is trivially (pun intended) easy to get those wrong.

I think the concept of a thought and what it is for a thought to be about something needs to be refined before we can say more about the second example. To begin with, if I see a dragonfly and mistake it for a fairy and then start to think about the fairy I saw, it isn't clear that I really am thinking about a fairy.
