How do you know something is true if you can't say why it is true?
That exactly is my point: why do you have to be able to say
why your perception of truth coincides with an absolute truth in order for your perception of truth to coincide with that absolute truth? It could coincide, without you even knowing that it does, or caring that it does!
Well, the student could be hallucinating the whole thing. How do they know they aren't? They can only have faith in their perceptions, at the end of the day. Seems to me truths mixed in with faith isn't a reasonable path to the absolute truth.
Of course the learner
could be hallucinating, or a whole myriad of other reasons why the learner's perception of truth is not coinciding with absolute truth. However, that's not how I defined the scenario. I said, the learner did in fact achieve 100%, and also believed (for whatever reasons) that s/he achieved 100%.
Does the fact that the learner, at a particular point in time, is not in a position to prove that s/he achieved 100% mean that said learner, at that point in time, did
not (absolute truth) achieve 100%?
I still don't get why you think it's necessary that a subjective truth must be proved to coincide with an absolute truth in order for it (subjective truth) to coincide with it (absolute truth). In order to
convince someone, sure, you would probably need proof for that. But for it to merely coincide is not contingent upon any proof. For that it only has to coincide.
