Exactly. I'm trying to show that that model is wrong.
And, as you've been repeatedly told, you don't get to do that in the context of the term of your statistical model that deals with materialism. When reckoning that term, P(E|H), you must do so as if H were true, whether you believe it to be true or not, and even if your overall goal is to falsify it.
I'm trying to show that the self must continue to exist after the death of the brain.
That's your overall goal, yes. But at this point in the proof you're trying to reckon P(E|H). You must do so using H as it is formulated, and you must assume it is true throughout this portion of the inference. Otherwise you're not performing a correct statistical inference; you'd just be using pseudo-mathematics to conceal a blatantly begged question.
Your whole notion of "potential selves" as discriminable entities is to pretend to justify the Big Denominator you announced ahead of time you would need in order for your proof to work. Insofar as you are using the Big Denominator only to argue that P(E|H) must be very, very small, it has meaning only within the P(E|H) term of your formula, part of the likelihood ratio. Hence all the concepts you use to justify the Big Denominator must fall under the auspices of H and not just be something you made up.
Leaving aside that there's no countable set of "potential selves" in materialism that gives a meaningful probability, your bigger problem is that you can't use an assumption that H is false, or the premonition that you can prove it false, as a premise in constructing such a proof with respect to P(E|H). First, that's just blatantly circular reasoning. Second, it's expressly not how the likelihood ratio works in a statistical inference.
One of my claims is that the materialists and reincarnationists are talking about the same concept/experience (the "self") when they discuss the possibility of life after death.
That claim is expressly false. Materialists do not allow for any such effect or entity as reincarnation would require. I presume Dave Rogers has said this in a typeface large enough to preclude your selective attention. You may not rewrite materialism to make it easier for you to refute.
I represent the materialist model by OOFLam and the likelihood of your current existence under that model.
You misrepresent the materialist model by just making up a bunch of stuff and calling it materialism. When reckoning P(E|H) you must consider H as it is actually formulated. You don't own H. It's not yours to speculate around. You may not rewrite it at will to suit your attempts to falsify it.
As I have written many times, and as I have outlined
here as fatal flaws #1 and #3, you simply have no idea how to properly formulate a statistical inference. Had you done what I've asked you many times to do and take an hour or so to address briefly each of these fatal flaws (or shown your utter inability to do that), your critics would not have to waste their time with an obviously incompetent attempt at proof. Your proof is not broken merely in some irrelevant nuance or by some niggling detail. Your proof is broken at the fundamental level of understanding how math works.
You're wrong and you know you're wrong, as evidenced by your assiduous avoidance of a comprehensive rebuttal to your claims. Please concede the debate and apologize for wasting your critics' time.
