For me it is the ultimate question. Who am I . What exactly is this "instance" of consciousness sat in front of an Apple Mac typing stuff to people I have never met around the world.
Belief in an inner essence, or central core, of personhood, was called "ego theory". The philosopher Derek Parfit put it starkly: we are not what we believe ourselves to be. Actions and experiences are interconnected but ownerless. A human life consists of a long series - or bundle - of enmeshed mental states rolling like tumbleweed down the days and years, but with no one (no thing) at the centre. An embodied brain acts, thinks, has certain experiences, and that's all. There is no deeper fact about being a person. The enchanted loom of the brain does not require a weaver.
Parfit devised a famous thought experiment. Imagine being teleported. A special scanner records the state of every cell in your brain and body and digitally encodes the information for radio transmission. Your body is destroyed in the process but reconstructed as soon as the signals are received and decoded at your destination. You "arrive" in precisely the same condition that you "left", identical in body, brain and patterns of mental activity. Your memories, beliefs, plans, skills and emotions are perfectly intact and you go about your business feeling and believing that nothing about you has changed in the slightest. It's just like waking from a dreamless sleep and getting on with the day.
If you are comfortable with this scenario then you should be comfortable with bundle theory. You appreciate that the observing "I" is no more than patterns of energy and information, which can be disrupted and reconstituted without destroying the self - because there is no self to destroy. The patterns are all. If, on the other hand, you believe that some essential "you" would be lost in the process then you are an irredeemable ego theorist. You believe that the reconstituted body is not "you" but a mere replica. Although the replica will know in its bones that it is the very person who stepped into the scanner at the start of the journey, and friends and loved ones will agree, you insist it could not be you because your body and brain would have been destroyed.
But these words you are now reading, whose are they? Yours or mine? The point of writing is to take charge of the voice in someone else's head. This is what I am doing. My words have taken possession of the language circuits of your brain. I have become, if only transiently, your inner voice. Doesn't that mean, in a certain sense, that I have become you (or you me)? It's a serious question. Written text is a primitive but powerful form of virtual reality. In the beginning was the word.
But there is is one doubt... simulation.... the theory that we don't actually exist except as an entity in a huge simulation. Oh, and another doubt, that there is a another Mort typing this in a parallel universe who is thinking exactly what I am at this moment.
Who are we ?.... tough question that one.
