I disagree at the moment. There are different planes of existence in Naruto. This is a known fact: spiritual, conceptual, energetic, metaphysical. So, it would be absurd to determine Amado by looking at a single expression and kanji. Momoshiki's range capacity is obvious, it would be a complete deception if he couldn't sense it in this plane of existence because assuming he's in a spiritual or different universe/pocket dimension, it would be impossible for him to sense it.
Modus Ponens: If P → Q and P is true, then Q is true.
Modus Tollens: If P → Q and Q is false, then P is false.
Hypothetical Syllogism: If P → Q and Q → R, then P → R.
Completely refuting the claims
If p - its existence is 4B
Q is true - Amados' reference was a 4-dimensional being
But if
P - its existence is truly 4D but Amado somehow detected it
(This is clearly wrong because Amado discovered the existence of a 4-dimensional God)
Then Q - shibai is 4D (which would also be wrong)
Why is it wrong?
A true 4D entity would be infinitely above 3D, so none of the 3D objects or characters could see or sense it because it is only a 4D entity, and yes, even if Shibai stood next to them, they would sense nothing.
Now a hypothetical comparison:
- p -> it is a spiritual entity, so -> Q somehow detected its existence.
Therefore,
P->Q
Now, reductio ad absurdum, the fact that amado can detect its presence leads to the absurd/impossible conclusion that shibai is 4D, because 4D is completely above 3D and therefore there is no way to detect it.
Now
Bandwagon Fallacy and appealing to authority
If they say
Everyone believes shibai is 4D, so it must be (majority)
When to object to authority
They say it's 4D because Momoshiki said it's above 3D
Even though there is no evidence proving Momo is 100% correct
