The fact another thing would pop into existence is irrelevant. 2+2=4-Not- in a universe where, when you have two things and two things, another thing pops into existence. In that universe, everytime you combined two things, you'd end up with fives things. Their addition would either reflect that or be wrong with respect to what -does- happen, in their universe, when two quanitities of two things are combined. Yes, yes, I know, I know, acording to what we know and what we call both logic and math this is nonsensical. I know..

So, now that we're done with that.......
Quote:You're equivocating..............................................................holy, shit, Ham..............

To equivocate, with the statement above, I would have to be using different senses of any of the terms employed above, which I'm not. In their universe, that operation, of those quantities, yields that sum..in each case, exactly how we have defined every single term. Tw is two, as in two pebbles in my hand. Plus is adding things together, as in adding two pebbles to two pebbles, and 5, is five pebbles, as in the sum - in that universe, of two pebbles added to two pebbles, in my hand. That doesn;t happen here.
I know

It does happen there, that's the proposition.

THAT is the implicit truth of The Law of Identity and THEREFORE it's true in all hypothetical universes.

You haven't seemed to realize, despite my stating plainly and more than once, that I'm not disagreeing with you. I'm simply reminding you that what we both agree on does not speak to the point of contention itself. Assume that all of it is true, assume that such a universe exists, assume that such an operation of such quanties yields such a sum. Are the rules which lead to such things being true..there, not here, -in that case-, in your opinion, logical? Why or why not? That;s what the OP is asking you, he's restated that this, and not all of the other stuff is what he;s asking you...I have explained both how and that this is all that he's asking you....and you have replied to that, to us both... by speaking to a host of other things. It's not, imo, that what you have said..by and large, is untrue, but that it is not relevant, or an objection to the point of contention.
It's a difficult to parse question (or not, going the route of strangling it in the cradle as I would, lol), because it asks us to employ logic towards the illogical, granted...but you can maintain, you can overcome that difficulty, I'm sure of it.
