This is my hypothesis. The mind is not a object but a process, it takes information from the outside world and transforms it into pattern. That pattern is not the mind, it’s just the way the mind sustains itself from moment to moment. That pattern still exists when you die, albeit temporarily until decay sets in, but we aren’t alive because the mind isn’t receiving any new input.
Now that doesn’t mean a consciousness can’t be revived, the pattern is still there, and if the process can be restarted then I suspect the consciousness would continue as if nothing happen. One moment about to die, the next revived. This is essentially what proponents of cryogenics expect to occur.
Did I just contradict myself, by saying that consciousness can be revived from the pattern, even though I claimed the pattern wasn’t the mind? I don’t believe so. The pattern is the painting, the mind is painter. In humans, the painter is the physiological processes that generate the electrical signals shooting through our body and that update the neuronal structure in our brain.
