That’s the strong claim. I don’t get frustrated when people disagree with that. I get frustrated when I’m black listed from making weak claims. For example:
Weak claim:
under similar conditions, similar effects can be experienced to the degree that they can be inferred to be similar (even if they cannot be directly known)
Ie. this pertains to pain and the recognition among people that it can be “related to” - in the sense that, without knowing a particular pain in another person directly, we can infer the nature of it - having experienced similar conditions and effects ourselves. We never know it exactly or directly; none the less; we can relate to it.
Strong claim:
the neuro-correlates of a pain experience equate one to one with the experience itself.
Ie. At some point in time it may be possible to scientifically understand the emergence of pain from biological correlates to the degree that the “subjectivity” will be removed from the experience if and when our understanding amounts to a kind of determinism.
Ie. the Self is an illusion. The idea that pain is personal assumes the existence of a person. In reality there is no person, there is only pain. And that pain may be entirely explainable in physical terms.
Ie. it exists in an objective sense to the degree that there is a field of reality in which it has arisen.
