Sigh. I feel like I'm the only one here who understands the implications of the truth of the law of identity. It's a truth that all hypotheticals and premises are based on and what universe is irrelevant. You can't entertain absurdities without entertaining absurdities. It doesn't matter even hypothetically what other laws there may be in another universe the laws that the other universe has has to at least have the laws that the other universe has. A has to =A.
There's an implicit premise within all hypotheticals that A=A. You can't begin a premise or a hypothetical without it. So any hypothetical that says the law of identity doesn't apply is already self-contradictory and a failed premise.
