As promised, I will reply and try to explain myself.
First off here's a post by Derp Obito about the eye itself: That's highly improbable, the Rinnegan is the Eye of Samsara, the Eye of Suffering. Since he suffered to fight and seal the Juubi inside him. If the Sage was born with the Rinnegan then the Eye would be called the Eye of Bodhisattva aka the Eye of the Sage, if Rikudou acquired the Rinnegan through meditation and learning then it would be called the Eye of Nirvana aka the Eye of Enlightenment. So it is a logical certainty that the Rinnegan came from the Juubi.
This was to debunk the theory that the Sage of the Six Paths was born with the Rinnegan. It is illogical to assume he was born with the eye of the Progenitor of the World, seeing as he only became a Divine God, AFTER he sealed the Juubi in him.
My premise therefore lies in the fact he gained the Rinnegan because of the influence the Juubi's chakra had on his body, and it mutated his eyes. So I hypothesize, on top of the foreshadowing from 629, that if someone were to gain the collective amount of chakra that comprise the Juubi (The Bijuu's like Naruto go) they would be able to awaken the Rinnegan; hence the reason why I say Naruto would get it."]
Madara reverse engineered the two brother bloodline, which is the other logical way of getting it. One brother represents Yang, the other Yin. By applying the Yang portion to the Yin's eyes, it mutates the eyes into the Rinnegan, successfully reverse engineering the original bloodlines. It is also highly probably that the powers both brothers obtained were more so in credit to the Juubi rather than their father; Mokuton being the peak of the Younger Son (Juubi's body), and EMS being the peak of the Elder Son (Juubi's eye). Therefore logically, like Madara did, you can reverse engineer the two bloodlines to comprise what the Juubi's influence had on the brothers.
Hope this covers that.
Hmmm. Interesting...
I think there's more discussion to be had. Let's begin.
With regard to the portion in red:
I can't completely agree with this "
logical certainty."
This "
certainty" is based on a logical fallacy, or rather, a few fallacies.
This first fallacy involved is the propositional fallacy known as "Affirming a disjunct." Basically this means that you are assuming that two conditions are mutually exclusive and thus concluding that because one disjunct is true, any others
must be false. (A or B; if A is true, then B must be false) We don't know for a fact that the Rinnegan was awakened due to one thing in particular. It could have been a multitude of events that led to its arousal in the forward direction, as opposed to the singular event of "reverse engineering" which we have seen proven in the manga.
The second fallacy involved is the formal "Appeal to probability." This one takes an inference based on inductive reasoning and makes the assertion that because something is
probably true, that it will be true.
Thirdly, the final fallacy here is the informal "genetic fallacy." This fallacy assumes a conclusion based on something or someone's origin (just as you propose the name suggests its origin) rather than the current context. An example of this would be like saying that the Volkswagen Beetle Cars are evil because they were first manufactured during Hitler's reign in Germany.
Do any of these fallacies make your guess likely to be wrong/incorrect? No. Your guess is fine.
You just can't state that the SO6P acquired the Rinnegan due to the influence of the Juubi as an undeniable
fact, as you did in the
blue portion of your post. As I said before, you've made a good hypothesis. However, it's a hypothesis and nothing more. Don't confuse extrapolated guesswork with interpolated fact. That's all I have to say about the sentence in blue.
Regarding the portion in green:
As long as the premises you've presented above do indeed prove to be correct, then this thought process is definitely a good one in terms of plausibility. I like it. Only time will tell how Kishimoto decides to handle the situation.
I beg of you, please please please don't claim to be logical and then break the rules of logic with fallacious statements. Do I sometimes generate fallacies? Yeah, I'll admit, I can screw up too. I'm not afraid to let others correct me either, because I'd like to continue to improve upon my ability to provide quality argumentation. You have great potential and I want you to capitalize on that. Don't let my constructive criticism get you down. Just keep up the good work, bro.
