One of the hardest obstacles to the realization of the self is the belief that our being and our mind are the same. The common belief that mind is an epiphenomenon of matter, that neurons create consciousness, has become ingrained as a truth. But this is not true and you do not need a Masters in Quantum physics to know it that it is not true. Life itself is a metaphysical thing, you cannot measure life, weigh it or in any way separate it in a laboratory. There is no proof that life exists, yet we KNOW it does, we see it! The cat is alive, the cat is dead, what is the difference? If one day we make a robot cat that eats, sleeps and behaves just like a real cat, is it alive? Of course not, you say! But perhaps we are just that, how do you now that YOU are not a Replicant* , a simulated human being? You do not know that because you do not know what being alive is. Your memories were implanted 10 minutes ago, can you prove otherwise?
Anyway, the ONLY thing you can be sure of is that you are conscious, whatever that might be, replicant or not. Not only that, all you ever know about life and reality is various forms of that consciousness. I might wake up and suddenly realize that everything about my life has been a dream**, my birth, my school, my failed relationships, my blogging, everything. This is an unassailable truth. So, I was never born and so I can never die. So if I was never born, and there is no proof that I did, who was dreaming?
* a Replicated is an artificial human being, an invention of the writer Phillip K Dick and brought onto the screen by the film Bladerunner.
** This is of course the theme of the film Matrix.
