Maybe I'm missing something, but I don't see the argument for the
paradox. Part of my trouble is that I'm not sure what "about" is
supposed to mean here. But waiving that, suppose (p) is about (p). How
does it follow that (p) is not about (p)? Even if we assume that (p) is
true, (p) only tells us (by instantiation) that, if (p) is NOT about
itself, then it is about something else. But the supposition is that (p)
IS about itself, so (p) tells us nothing.
