This topic always seems, as a scientist, to make me scratch my head. I am baffled. Maybe someone can help me!
Bernardo in Brief Glimpses in a positive sense, puts forward the simple if/then statement and verbiage:
"If all reality is in consciousness, then your consciousness is not generated by your body. Therefore, there is no reason to believe that your consciousness will end when your body dies. Your body is simply the outside image of a particular configuration of consciousness that you experience when you are alive. When you die, that configuration – or state – of consciousness will change, perhaps dramatically. Changes in your state of consciousness, however, happen all the time: when you wake up suddenly from an intense nightly dream, your consciousness changes its state rather dramatically as well. Now, would we live life differently – perhaps in a less anxious, more present and grounded manner – if we knew that death isn’t the end of consciousness? If the fear of death were no longer viable as an instrument of social control or economic gain, what would be the practical consequences for our culture, economy and society at large? And if you knew that your consciousness isn’t going to end when you die, wouldn’t you be interested in investing a bigger part of your life in preparing yourself for the transition – so it isn’t traumatic – and perhaps for what might come next?"
Ok, we idealists accept, OK the brain is not the projector, projecting subjective consciousness outward onto the world (with we also experiencing it, but Im getting ahead)---so, unplug the projector and consciousness does not vanish. Fine, it may become drastically altered from your point of view, but that happens all the time in breathing waking life. This is not the part that makes me scratch my head.
Now I walk up to a materialist scientist in his laboratory. I ask of course, "What are you trying to measure."He says, "I want to measure this voltage". So I say, "You will experience that by looking at this multi meter or oscilloscope to believe that it exists." He looks at me quizzically but then says, "Duh." He agrees. So I switch to lawyer mode, hopefully entrapping him, like he does with his measurement. "Well, you might as well say, it doesnt exist until I measure it, at least for you: you wont write the paper until you experience it." He thinks he may be about to get the better of me and says, "No, the device in this state is generating a voltage, (electrons and lots of them are moving) and it would be here whether or not I measured it." Referring to something irreducible existing outside of, at least his, consciousness.
I say OK fine those are physical things, that you say exist but most likely wouldnt submit a paper until you verify it yourself. Maybe even get other people to verify it, same set up, same measurement! He says, "That would be best. Then I wouldnt have to believe, I would KNOW!"
So I say, "What about this other thought "inside my head" (he can't see the quotes) that I'm not telling you about, measure that and tell me what it is!" He says, "there is no way to do that. Only you left-wing Jungian influenced new age airhead types believe in mindreading!" I said but what difference is that than a voltage, my brain is a device and generated it." He thinks for a moment, "Gee well, science certainly will be able to, some day, measure that and say with absolute certainty what it is!" At this point I am convinced he either skipped all his quantum classes or slept through them. "What if I told you the human brain is incapable of intellection, that there is not way to view a screen of his mind to evaluate what an individual perceives as "red" when they look at a screen." Ok, he says, "If my brain doesnt generate consciousness then what part of me does, my ass???" I do my best not to agree instantly with him.
I say, "How do you know I even had a thought I wanted you to read" "You told me so, I'll give you the benefit of the doubt because you are standing here talking to me, and alive, and don't lie that much." Moving in for the kill, I say, "So if I was laying down, dead and a known liar you would not think I had thoughts you or science in some dim future might be able to read." "Duh, he says, if you're dead YOU wouldn't even be able to generate a thought let alone reflect on it so I might believe it or ever transcribe it."
"So let me sum up, you are measuring a voltage, experiencing it, others have duplicated your experiment. You moved from theory to belief to acceptance and knowing based on the the standalone experience of the voltage, your experience of the voltage and others' duplicative measurements.
Now you are accepting as fact a state that can neither exist nor be measured, that no one has be able to experience subjectively as you say, because there is no experiencer (according to you), the non-experiencer has never come back to tell us about his non-experience (except every year on Easter and according to growing NDE literature) and there are not scientists duplicating all these non-experiences, and you all are convinced that when youre dead youre dead.
If that is not a non-scientific religious belief system, I have never heard one." He walks out silently in disgust. But thinking, which is spiritual.
