2+2 will always be 2+2 or IOW will always be 4 or 1 more than 3 or 1 less than 5 or any more expressions of two things and two things/four things. What universe it is or what logical laws those universes have is irrelevant. The Law of Identity can't be violated even hypothetically. It's an absolute law that must hold everywhere. It doesn't matter whether beings exist to conceptualize it or not. The truth of the law of identity =/= the existence of the concept of it within the minds of beings. The Law of Identity transcends cosmology and physics.
Again:
It's impossible to describe any universe without the Law of Identity. The truth of the law of identity is implied before any premise or hypothetical can even be made. Period and full stop. To describe anything is to give something an identity in the same sense described within the concept of the law of identity itself. The truth of the law of identity is implied and it was implied back in the stone age before such a truth was conceptualized, and it was true before humans existed or before any life existed and it would be true in any universe you can imagine and even any universe you can't imagine. That something is what it is is true everywhere regardless of what that "everywhere" is.
It can't be true that A=not A. That can't be true anywhere. That's a law that must hold everywhere. In all universes, in all dimensions, both real and hypothetical. That's the law of identity and that can't be false.
Whatever other logical laws you're talking about in other hypothetical universes they must at least be whatever other logical laws you're talking about in other hypothetical universes . THAT is the implicit truth of The Law of Identity and THEREFORE it's true in all hypothetical universes.
A must=A and if there is no A then not A must = not A. That's The Law of Identity. It's absolute and transcends all hypotheticals because it's already presupposed before a hypothetical can even be hypothsized.
Whatever 'other logical laws' there are, there must at least be the Law of Identity.
