In other words, all you can really say for sure is that "A is A ... at this instant."

Oh, my gosh -- that is exactly what "A == A" means!!!

You didn't know that, and write offhandedly that this is *all* we can say? That's what everyone has spent hundreds of posts trying to explain to you!!!

I believe the general is not this dense, he's just arguing for the joy of making words.

You, on the other hand . . .

I am done with this conversation, I'm afraid. Off to a movie, then dinner with the wife.

Have a nice day.

Yes, "all." You've got an instantaneous state that may, or may not be changing, and you don't know which. For the claim to be the basis of an objective system, you must assume that A is unchanging. Otherwise, if A was "this" at this instant, and has changed to something else at the next instant, which version of A corresponds to objective truth? On what basis do you make your assumption that A is fixed? How do you prove your assumption is correct?

That's what everyone has spent hundreds of posts trying to explain to you!!!

No it's not. You're making things up now.
