I do not wish to start a debate so anyone who is religious or believes in souls or the afterlife please stop reading...
I started thinking the other night about immortality and how it could be achieved through Science. I believe that the human body has no soul. The only 'soul' it has or is, is simply a series of brain connections. These brain connections create a spark. This 'spark' is the essential 'you' which cannot be pictured in the imagination. This spark was created by your brain in all of its complicated brain connections. I do not believe in 'souls' because if we did really have a soul that moved from body to body wouldn't it be justifiable that we would 'remember' these past bodies and experiences?
Now if all we are is brain connections then we are essentially a organic machine. We are not our body or our brain..the only thing we are is those brain connections which created ourselves. What if before we die our brain was preserved and fed oxygen and blood and everything else it needed - couldn't we be kept alive until we had the technology to do a body transplant ?
Ok - taking it a step further what about finding those 'brain connections' which make us up. couldn't we somehow transfer those connections to another brain when technology permitted it ? Could we then achieve immortality ? When you think about the body and Science you understand that the body and brain is nothing more than a machine. What if after death those 'connections' were turned back on - we would essentially come back from the dead.
Taking it a step further one more time.. what if once we have those brain connections which are 'consciousness' what if we found some material or liquid which can preserve and keep it in a timeless state - then once the person is ready to come back to life it is simply connected into a new brain.
