Good post, thanks for the response.
Prove one hundred percent? No, we can't. Can we prove it well beyond reasonable doubt? Yes, we can, and we have.
There is no evidence of life after death. Every single investigation into life after death has turned up squat. The universe acts exactly as though there is no life after death. Thus there is no life after death.
I'm probably just being ignorant here but what studies have been carried out and what results have been found? Feel free to post a link to a resource here instead of spelling it out for me
"True", in this context, means "an accurate description of the universe". This isn't exactly controversial. It's just what "true" means: that a statement is factual.
To exist, an entity must have an effect on the universe, even if this effect is miniscule. If an entity has absolutely no effect on the universe, it does not exist, because it never interacts with anything else in any situation and causes nothing to happen. That is the definition of non-existence.
The universe we observe behaves in all situations exactly as though there is no afterlife, because it has no effect on our universe. Thus, it does not exist. Saying that it exists "in some other way" doesn't work either; it's the same thing as saying that the Trix rabbit exists, but he's invisible, immaterial, and undetectable by any means.
Firstly, I just want to point out that I agree 100% with the principle that no evidence against is not grounds to believe as then it is faith and not belief based on any rational principle - which is why I am merely interested in this and not a firm believer as yet.
So as you've stated, to exist, physically, in our physical universe then yes and entity must somehow effect our universe. It appears so far that there is no cast iron proof of this concept - just anecdotal evidence from the observer which is hard to replicate or prove. For example, reading one of Monroe's books where he discusses, whilst in a state of OBE, pinching a woman in her home that he knew and she remembered the following week when asked and had a mark on her sweater where this had taken place. Now obviously, to believe that without experiencing first hand is like believing that the bible is real, so we can discount these notions for the moment.
So that just leaves your Trix Rabbit example. Which is where I think that we can't discount something entirely. I just feel that we don't know nearly enough about our own consciousness, what is this consciousness? Are there other types of consciousness and if so, how do we explain them? Do they even need to have an impact on this universe? In normal waking consciouness they are all bascially the opinion of the observer. Different experiences lead to different opinions.
As jfish mentioned, there is no proof to everyone's satisfaction, because the examples seem to occur as a phenomena and are hard to recreate.
Again, purely anecdotal, but there are some examples in a book I am reading on Lucid Dreaming by a guy called Robert Waggoner that are interesting. I wanted to get a book on these states that is a different perspective from Monroe. Once in control of the dream state and 'lucid', interacting with the dream characters has apparently revealed things that the dreamer didn't consciously know. Which is interesting, if true. Obviously there are other possibilities, like subliminally hearing something and not realising and it coming out in this unconscious state.
IF (big IF) there is more to this than picking something up subliminally then, to me, it's well worth investigating (and I'm not doing much else when I'm asleep anyway).
I've rattled on too long there and probably typed a lot of pish, but I'd like to think that my approach to this is skeptical. Just not enough to say, "Not enough evidence, not worth pursuing".
I didn't say that the exploration was useless. I said otherwise, actually. If you explore the evidence and find an effect that the afterlife has on our universe, then you can prove that the afterlife exists.
I am glad you have this opinion, but looking through previous comments on the thread, it would appear on a skeptic forum that a large number disagree with you that there is any point in experimenting any further with this.
No one else is, either. We simply say that, before you can say that there is any reason at all to even consider the notion, you have to have some evidence. So far, there is none, so we discard the possibility until the evidence becomes available. And, at this point, it's been shown to be beyond reasonable doubt that the evidence will not be forthcoming. Barring some reality-shaking alteration in our understanding of the universe and the way the world functions, there is no way for the afterlife to exist.
Kind of summarised in my previous response, but, I don't feel there is enough evidence against pursuing this further, trying to become lucid in my dreams regularly (which I find enjoyable anyway) and attempting to replicate this OBE phenomena.
For what it's worth, I think and OBE and a Lucid Dream are the same thing, however, when inducing an OBE you basically are aware of the full experience of falling asleep, when usually you are unconscious when you drop into this state. However, when becoming lucid in a dream, things have already happened in the dream and are happening so it's more confusing as to what's going on.
