The truth is we don't really exist. Our bodies do, but what we think of as our selves is really an illusion of continuity created by the brain. When the brain stops thinking, we stop existing.
I strongly agree with spider on this as briefly outlined in this post:You can't have it both ways, those statements contradict each other. We do exist both body and mind ...
From: http://www.sciforums.com/showpost.php?p=2757580&postcount=21 ,but for much more detail and many observed supporting facts in many different fields (neurology to historical events) which can best, if not only, be understood from the Real Time Simulation POV see the link given in the above quote.Yes as Chambers said "consciousness is the hard problem." I doubt any set of hard ware can ever be made to have even simple experiences ("Qualia") that humans have all the time.
However, I think we have them because the brain, specifically the parietal part, is running a real time simulation and creating "us" in the process. I have also suggested that because of this genuine free will is not necessarily inconsistent with the natural laws that control the firing of every nerve in your body. See how I think we have experiences and may even have genuine free will (but I doubt that) at: http://www.sciforums.com/showpost.php?p=905778&postcount=66 ...
SUMMARY: My POV is not that we are living in simulation, but that we are part of a real time parietal (brain) simulation. I.e. "we" are not a physical body, but an informational process. Note "I" ,"we" "us" etc. in quotes refers to this created psychological self not the physical self /body.
I will just mention two of the many medical facts supporting this strange POV that "We" are NOT physical bodies; Or as Spider put it (except for periods of deep dreamless sleep) “we” are: "illusion of continuity created by the brain." Or in my own terms, "We" only exist when the Real Time Simulation in parietal bran is executing, creating the world we perceive, our qualia and "us." We do not exist when our body is in dreamless sleep, or dead.
After a large parietal stroke, one side of their body is not recognized as being part of them. In one case, reported in the literature, the attending doctor picked up their hand, which for them was not their hand and asked: Who´s hand is this? "Yours" was the patient reply. Then the doctor showed his two hands and asked: How can I have three hands? The patient replied: "Because you have three arms."
Quite commonly when patient is first recovering from their stroke in the hospital bed they will call the nurse, and complain that someone´s leg has been left in the bed. It is disgusting! - Please remove it; or in a few cases try to throw their physical leg, which for them is not theirs, out of the bed.
People with "phantom limbs" are the exact opposite case - Their self, constructed in parietal brain, has four normal limbs despite their body having only three. They consciously learn the phantom is not "real" but for them it is real - just as real as their physically existing limbs.
This statement is not based on only their self reports, but also on their automatic (unthinking) behavior. For example, if the phantom arm rigidly extends out from the body, and they are asked to quickly run thru a maze with many narrow doors or passage ways, they automatically twist their body, as you would, to keep their non-existing arm from banging into the side of the door frame, etc.
"Out of body" experiences are caused, usually, by being the reality created in parietal brain. They are not physically real, but are real as it is only by or based on this directly experienced reality upon which we INFER the physical world does exist.
