What happens to consciousness when we die? I have just read the many entries on this thread, which seems to have resurfaced, and it feels like about 10 years ago since I started the thread. That is because I have done so much thinking since that time in many discussions of consciousness on this site.
I do see a big problem with the idea of the existence of any disembodied form of existence and I do see this as a big argument against life after death. I believe that this is why a lot of ideas about life after death have been about ways to enable physical bodies to survive, in the prospect of reincarnation or resurrection of the dead. Of course, I realise that some of these ideas may be based on wishful thinking. I thought that
@TheMadFools question about whether consciousness could be transferred to artificial brains is interesting. This is because the idea of brain replacement is one idea within the transhumanist picture, but there is the underlying question about identity, and to what extent this would survive.
I was extremely interesting in the thread on the theory of blind brains and consciousness started yesterday, because it is one which is trying to understand the nature of consciousness in relation to the working of the brain. I think that the whole idea of consciousness and subliminal levels of perception is extremely relevant to the idea of thinking where consciousness ends. I believe that even ideas of panpsychism come into play.
I think that many people, from all angles, try to come up with clear answers. In some ways, this may involve a wish for an afterlife, and I am not sure if I even want one, and it would depend on what this form of existence may constitute. From reading on this thread, and other reading, I can see the logistics of the arguments of physical materialism, but do not see them as absolutes because in so many areas of thinking about consciousness, including physics, as well as philosophy, there still remains a certain amount of uncertainty, particularly in the understanding of the nature of consciousness.
