I feel like this needs to be worded in the draft :v
Sure thing. Would something like this work?:
Characters who can affect objects with a number of dimensions equal to the cardinal aleph-2, which in practical terms translates to a level that completely exceeds Low 1-A structures to the same degree that they exceed High 1-B and below (Although they don't necessarily need to transcend infinitely-many Low 1-A structures for this). This can be extrapolated to larger cardinal numbers as well, such as aleph-3, aleph-4, and so on, and works in much the same way as 1-C and 1-B in that regard.
Makes me think about how mathematicians at times say something is true "almost everywhere" if it is true on an uncountably infinite set with the same cardinality of exceptions to that rule
True enough. I should've probably been more specific with that description, so, that's my bad. I guess "any sentence describing a certain cardinal number" would work better as a definition.
Honestly, I feel like using statements like "above all mathematics" as actual Tier 0 evidence isn't better than using Omnipotence as evidence.
Like, I get it, it's tempting to say that if the character is already 1-A and depicted as practically omnipotent we might as well start to take statements we would usually discard as No-Limit Fallacies literally.
But we shouldn't give in to that. Ultra high-tier characters should be held up to higher standards of scrutiny, not to lower ones. Statements like "above mathematics", "above logic", "transcending everything at all levels" etc. should still remain in the realms of just things that were very explicitly addressed in the verse and not stretched beyond that.
I feel KingPin already tackled your points in regards to the first response well enough, so, I'll just give my thoughts on another aspect of this one.
Anyway: Even outside of the point he made, this kind of argument hits a wall when you take into account the fact some things naturally segue into others, meaning we are thus forced to consider them lest we start cherry-picking what parts of math we want to exist in a verse, for what is next to no good reason, in my view.
Like, for example, in ZFC, proper classes like ORD, V, ON, and etc don't exist as actual objects that we can refer to (As sets are), in much the same way infinite sets like N technically aren't "real" in a finitist formal system, but if we switch to a theory where we are allowed to quantify over them, then a lot of large cardinal axioms naturally emerge without having to be directly posited, by means of the Reflection Principle, something which I talked about in my above response to you. That example being something I specifically use because we do have characters who are identified with some Universal Set in their verses (Unsong's God, and in the future, the White Light, too), or have the ability to control such a structure (The Downstreamers), with said Universe being obviously something very real in those cases.
We can reduce that same argument to a smaller scale, too: Surely, we assume a set as simple as the real numbers exists by default in a verse, and so it naturally follows from there that the set of all subsets of the real numbers exists, too, and so does the set of all subsets of that, and so on. Things like that just emerge as a natural result of the basic assumptions we have to make for indexing's sake, and so arbitrary cutting them off doesn't seem very appropriate here.
You might say that this would allow any "beyond math" statements to qualify for ultra-high tiers, but that doesn't come off as very convincing to me, especially since even under the current kind of assumptions we make, some space with a countably infinite number of dimensions would have to exist at least as an idea, in pretty much any verse, and yet we still don't slap Low 1-A or 1-A onto any character stated to transcend mathematics. We'd just have to be careful and require very proper context in regards to this kind of statement, in my opinion,
especially if it's throaway and/or not at all something that elaborated upon.
What do you think about Qawsedf's and KingPin's suggested modifications to your draft?
I like KingPin's suggestion more, if only because I'd want to simplify the descriptions as much as possible, which in my eyes means distancing them from the current ones. Although I admit I don't see how they're much different from mine. (Might be the tired brain speaking, though)
