SN 12.70 applies here. It demonstrates that for some arahants (most? could it be... ALL of them?) the regularity of the Dhamma is seen, but they do not see past lives or kamma-vipaka for beings.Mkoll wrote:For the sake of argument, let's say someone is agnostic about rebirth and they practice diligently and attain arahantship. Are they then still agnostic about rebirth?
Unless they overestimate themselves, they know that the cessation of ignorance has occurred & therefore that there is no more coming to any state due to the lack of necessary nutriment for such an event. At the same time, they do not have any confirmation of pre-/post-death continuities (meditative visions of such things are not confirmation of them as ontological facts, but simply ongoing evidence of their having a foundation in feeling, per DN 1).
...so, what's the problem again? Staying within the scope of the OP, the goal is dukkha-nirodha, not rebirth-nirodha. (The former is alleged to mean the latter, but this always remains an inferential conclusion. The former, in and of itself, is the point.)
