I remember there are 4 things that qualify as Low 1-A back then which is:Yeah, I previously concurred with tiering Absolute Infinity as Low 1-A out of an equation to a proper class but I realize the above is just correct. A proper class includes all sets, but within the framework of set theory itself you can go, in a sense, "further" than them. You can make products of proper classes (Like ORD², which is the class of all 2-tuples of ordinals) and in category theory you can extend that to conglomerates thereof, and so on and so forth. Meanwhile "Absolute Infinity" in the naive set theory sense is applying the definition "Set of all sets" to an unqualified notion of "set" as meaning any collection whatsoever. Meaning it includes everything, including itself (Hence it's a paradoxical object). Nothing is further than it.
So wrt to Absolute Infinity you either: 1) Try to make it quantitative and so arrive at an impossible (re: untierable) object, because the "quantity of all quantities" isn't a thing. 2) Try to go with Cantor's theological view of it and argue it's Tier 0 (Which obviously can't happen here).
1. Von Neumann Universe
2. Multiverse Type 4
3. Absolute Infinity
4. Set of all sets
Given Absolute Infinity does not qualify for Low 1-A due to it being treated as an universal set here, would it also apply to set of all sets too?
