Where I differ with many of you is that I'm willing to call a working brain a conscious thing. That doesn't help Jabba's math though.
You have tried this before. You are saying nothing new.- So, I need to back further up...
- Somehow, we need to agree upon the thing/process to which I'm referring.
Then get yourself to publishing in the appropriate journals. By all means, try to convince others how the science is wrong. Present evidence.- I contend that science is wrong about the very temporary nature of this thing/process.

- According to science, there is a particular conscious thing/process that first came into existence when my physical body evolved to a certain complexity. This thing/process never existed before, will cease to exist when my body dies, and will never exist again. This is the "self" to which I'm referring.

Guys, are you really going to do this all over again?
Jabba's mistakes and faulty arguments have been utterly demolished already. Many times. If he doesn't already understand why they're worthless he never will. Just tell him to read the thread.

Dave,
- But each brain has a different consciousness, its own consciousness -- that it does not share with any other brain, that never existed before the existence of this brain, and will never exist after the existence of this brain.

- Not to worry. I'm back
- I don’t really understand the formula I’ve been using... I just accepted it -- it was in a book -- even though it didn't seem to make sense. I just assumed that I was missing something.
- Could be that you guys were trying to explain this to me and I either wasn't reading, or just wasn't understanding, your explanations. Obviously, I'm not admitting any wrong-doing -- I simply didn't have time to scrutinize nearly all of your posts, and naturally focused on the friendlier ones...
- Anyway, my first problem is that the formula always has the denominator larger than the numerator -- whatever the issue -- and the complementary hypothesis always outweighs the null(?) hypothesis.
- What am I missing, or misunderstanding?
P(H|E) = P(E|H)*P(H)/( P(E|H)*P(H)+P(E|~H)*P(~H)).
Good post! As to the highlighted, how is it misunderstood?You are not the only regular participant in this thread who does not understand the formula. A good many of your detractors also do not understand it, especially the ones who keep repeating the mantra "The probability that I exist is 1".
The formula, in plain English:
The probability that I would have come to exist given H is equal to (the probability that I would have come to exist given H times the probability that H is true) divided by (the probabiliity that I would have come to exist given H plus the probability that I would have come to exist given something other than H times the probability that something other than H is true)
The formula uses the observed existence of oneself as a test of the "H" hypothesis. The mathematical question the formula poses is "How likely is it that I would be observing anything at all if H is true?" The question is anthropic in nature.
The formula is formally correct. "H" and "not H" need to be approximately defined. The probabilies may also be approximated, if one is looking for an approximate answer to the question posed.
An approximate answer can be quite compelling, if one is convinced that the approximations are within reason, and that no reasonable change to any approximation would significantly alter the conclusion.
I think one might well use the formula to rule out "H", but what the alternative to "H" might be is another question.
Your difficulty, in terms of achieving your stated goal, is that the formula is entirely subjective. You might well use the formula to completely convince yourself that "H" is either correct or not.
But you cannot use the formula to prove anything to anyone else. The formula applies only to the user, and no one is compelled to be a user.
Many, in fact, would be unable to force themselves to be users even if they wanted to be users. Some people simply have no faith in probabilistic approximations.
I happen to disagree with those people. I think the ability and the willingness to make and use probabilistic approximations is essential. I think we all successfully use such approximations every day of our lives, and could not get by without them.
Additionally, I think there are many here among us who, aside from feeling life is but a joke, also do not understand that probability is not about randomness. Probability is simply a methodology for making fuzzy determinations in the light of incomplete information. In that sense, probability is useful when randomness causes our knowledge to be incomplete. But that is as far as the relation between probability and randomness goes. Probability works the same in a deterministic universe as in an indeterministic one. the formulations are the same, the ranges of outcomes are the same, the fuzzy determinations, and their reliability, are the same, whether the universe is deterministic or indeterministic.
Good post! As to the highlighted, how is it misunderstood?
