Tbh I'm very iffy on this because of the limited number of possible users in addition to the fact that the way we currently treat Law Manipulation would naturally lend itself to including logical principles as well. The very same page legit even lists "logical truths" as being encompassed by it
Idk, I'm kinda neutral, leaning toward disagreeing I think. I just... don't really see the point
With the Tiering System Revision Law Manipulation (of laws of nature and the like) would have
very different standards applied to it than logic manipulation. For something High 1-A+ (or potentially so under the right conditions) having guidelines written down seems worthwhile IMO and since those don't apply to laws I think a separate page is better for that.
I kinda disagree, or at least, I'd want this reworded. Existing in a logically contradictory state is Nonduality. Altering whether you exist in a logically contradictory state or not is Logic Manipulation that can grant/remove Nonduality. Creating a different being that exists in a logically contradictory state is Creation and Logic Manipulation, with the created entity having Nonduality (in the same way that creating a fire elemental is Creation and Fire Manipulation, with the elemental having Elemental Intangibility).
That's mostly fine. Manipulating your own logic can be listed as such, assuming that it's not a result of being nondual to begin with (as in, going from nondual state A to nondual state B because that's how those nondual states works by nature shouldn't count).
I kinda fundamentally disagree. If it's a High 1-A+ structure being manipulated, it's the fundamental structure for all possible worlds. If it's possible to mutate that, then it cannot be the fundamental structure for all possible worlds, since both the pre-manipulation set of logic, and the post-manipulation set of logic are possible worlds within that series; there's something more fundamental that allows both to exist. It's more like altering mathematics at that point.
That basically goes in the direction of "if it can be manipulated it can't be logic" and I disagree with that on grounds of that altering the nature of the ability by our preconceptions. An author should be able to write logic manipulation and be taken seriously.
Possible worlds only include
logically possible worlds, so until the logic was altered they were in fact impossible. They contradicted logic. If your definition of possible worlds includes changes in logic then it's simply
all worlds, as "possible" ceases to be a limit.
One can also see it like this: When we say that two verses' collections of "all logically possible worlds" are both High 1-A+ that's under a default assumption that these sets will be the same in both verses. We assume (by default) that logic is the same and hence all the same worlds are in that set. For example, both verses will have the law of excluded middle.
Now, let's say a logic manipulator deletes the law of excluded middle. You argue, the worlds that don't have that law should hence always have been included in their set of all possible worlds. Let's accept that for a minute. That would mean that their set of all possible worlds is bigger than the set of all possible worlds in a verse where the law of excluded middle is inviolable. (in the sense that it contains all worlds from the latter fiction. It contains the ones that abide the law of excluded middle, and additionally some that are not part of that set. I.e. bigger by a simple subset relationship)
Hence, while maybe not all possible worlds by their verse's standard, the logic manipulation would still have affected something on the scale of "baseline" High 1-A+: Namely the set of all possible worlds that abide the law of excluded middle, which is just the set of all possible worlds in fictions without logic manipulation.
It would make no sense for us to rank the same structure differently based on whether or not a verse features more things outside of it or not, so High 1-A+ "all possible worlds" must be judged by a baseline definition of "possible" not by a definition that varies between fictions. IMO that baseline definition would be regular first-order logic with the laws of thought and stuff.
If you affect "all possible worlds" by that definition of what is "logically possible" then you have affected a construct large enough to qualify for that Tier.
In the reverse, we wouldn't give out High 1-A+ for verses whose definition of "possible" is vastly more restrictive than that either.
But as you mentioned with the invocation of "my opponent existing implies I'm stronger than them", that sort of ability would still be limited by its in-verse showings. And even then, it seems plausible that a truly general precept of logic like that would be able to be bypassed and exploited by other characters (i.e. by changing such an immortal/transcending character to fundamentally be someone else, causing that law of logic to no longer apply to them).
I wouldn't take that as a flaw in the ability or its ranking as such, though.
But yeah, due to how feat bound Logic Manipulation is by necessity, it's far from impossible for there to be ways to cheat around the altered rules of reasoning.
Which leaves me with the usecase being such a niche of a niche that I think it would be misleading for it to be included on a page in any way similar to this. And in fact, it may be better to not include such tiering information at all.
Eh, better more information than less in my book.
Nitpicks/Grammar
Should be "if truly of", and should either have a comma between "fundamental" and "logical", or should replace "fundamental" with "fundamentally".
done
Conclusion
So should this page be included if I believe that all logic manipulation involves manipulating things that aren't inherent to the fundamental structure of reality, and so, are more akin to laws governing specific realities?
Probably not.
I think restricting these kinds of qualities to limited areas of space goes against the spirit of what was decided in the Tiering Revision, given tiering by nature and whatever.
Well, that or it says "all authors that claim their characters manipulate logic are wrong about their own stories, because if it's manipulated it's not true logic" which I personally think is actually worse. Paradox ability should be allowed to be actually paradoxical.
EDIT: Also, btw, the only example provided for Logic Manip actually had that ability removed from it
back in March.
Yeah, but if I see it right the argument basically was "by our current definition that's just law manipulation not a special power", which is correct as by our current definition logic manipulation is indeed just law manipulation. So I don't think that's a problem.
