AiA said:There has to be life after death, if not then what happens to our mind and soul which is eternal.
Hence, metaphysical. Beyond space and time.AiA said:Physicallity decomposes, elements of physics and nature, metaphysics is beyond space and time, if there is a time when mind exists and a time when it doesn't then it wouldn't be metaphysical.
AiA said:When the mind is dead, the human is dead hence life after death.
When looking at the fact as you state a co-relation between brain activity and experiential conscious states you are disregarding mind again, simple example, imagine a walking dog that smokes, can you imagine that. Now prove to me that you thought of that dog, you can't cause it exists only in your metaphysical mind.
AiA said:first off, I apologize for my self contradiction, what I meant to say is that when the brain is dead, the body is dead, hence the mind and soul live after life, once again, I apologize for that.
Secondly, I don't see why your trying to lower a human being to nothing more than a computer.
Secondly, you said that the neurons show elavating when thinking of such a dog, but the same can be said when thinking of a smoking cat, a flying horse, a walking snake, now prove that your thinking of one of these exact examples, though your neurons may increase in activity when using the mind, that in no way implies that the brain can determine exactly what is going on in the mind.
If thats the case then how can someone with photographic memory be able to keep all those thoughts locked up in that small little head of his.
Several theories have been proposed to explain NDE. We did not show that psychological, neurophysiological, or physiological factors caused these experiences after cardiac arrest. Sabom22 mentions a young American woman who had complications during brain surgery for a cerebral aneurysm. The EEG of her cortex and brainstem had become totally flat. After the operation, which was eventually successful, this patient proved to have had a very deep NDE, including an out-of-body experience, with subsequently verified observations during the period of the flat EEG.
With lack of evidence for any other theories for NDE, the thus far assumed, but never proven, concept that consciousness and memories are localised in the brain should be discussed. How could a clear consciousness outside one's body be experienced at the moment that the brain no longer functions during a period of clinical death with flat EEG?22 Also, in cardiac arrest the EEG usually becomes flat in most cases within about 10 s from onset of syncope.29,30 Furthermore, blind people have described veridical perception during out-of-body experiences at the time of this experience.31 NDE pushes at the limits of medical ideas about the range of human consciousness and the mind-brain relation.
Well, that supports my view of the brain as a HETEROGENOUS pudding..hypnagogue said:The brain is not a homogenous pudding. Different regions of the brain specifically code for different things. Very likely, there is a particular set of neurons that codes particularly for the concept of doghood and its various associations, and likewise with cats, horses, snakes, smoking, walking, etc. In principle, we could differentiate thoughts about a dog from thoughts about a cat by observing that the set of neurons responsible for encoding 'dog' light up as opposed to those that encode 'cat,' and so on.
That small little head of his has tens of billions of computational elements (neurons) and hundreds of trillions of interconnections between those neurons. Something like photographic memory is really not that impressive a feat for a computational resource as powerful and complex as the brain.
hypnagogue said:Modern cognitive science clearly shows a correlation between physical brain activity and experiential conscious states. If anything, such a correlation is suggestive that as the brain goes, so does the mind; if the brain stops functioning, it is reasonable to believe that the mind does as well.
Is that a proof? No, but it's a compelling argument. You have yet to provide even that. "Metaphysical things are beyond the physical, therefore the mind is eternal" is not exactly compelling reasoning.

learningphysics said:Are you referring to my post? Ok, then nobody can make any statements about post death possibilities... whether experience continues or not. Every statement of this regard will be a "might" statement. The whole topic is a "might" topic.
