I’m convinced it all comes down to the metaphysic assumptions we absorbed when growing up. Seems strange?
Let’s examine the following. What would be the most intuitive belief regarding the nature of mind? That it is physical or not physical? You would have to agree that the second is much more intuitive. Of course it’s also more intuitive the flatness of the Earth and that the sun moves around it. This doesn’t mean that the Earth is flat nor that the Sun revolves around it.
So, why do we doubt what we can clearly see? Education. We have been taught that the Earth is more or less round and it revolves around the Sun. These are facts.
Are we then to assume that mind being an emergent function of the brain is also a fact? No. Yet, it’s this belief that is passed as a scientific fact or that we have good reasons to BELIEVE (this is hope) that one day it will become a fact. What is a fact is that according to many authors, it won’t.
So, the problem is that we are taking a metaphysical predilection as being a scientific fact. All known cases of emergent properties of natural phenomena, both the phenomena itself and its emergent properties, functions included, can be simultaneously seen using a single mode of observation. However, when we use instruments to observe neural events and all those electrochemical functions, we do not detect mental events. And when introspectively we observe mental events, we don’t detect the electrochemical reactions happening.
Neural correlates aren’t mental states. In fact, modern neuroscience has no idea on how the brain produces the “emergent property” of consciousness. However, their faith that one day such will be known, passes to the public as a certainty, not a hope, a belief built upon metaphysical assumptions.
So we are taught to believe that our mind is an emergent property of the brain and this hinders the possibility of accepting rebirth. But this is only difficult for those who have been, pardon for the word, intoxicated by the metaphysics of physicalism.
The fact is that we have a non physical dimension that we experience every single day, our consciousness. It has no mass, spin, charge, any physical property.
We intuitively assume that the death of the body may not mean the death of the mind, unless we have been exposed to scientific materialism ad convinced by it.This is the main problem, not only not accepting rebirth or karma. We start practicing Dharma while stuck in a metaphysical system of beliefs that actually is incompatible with it. In the same way that we only observe nature according to our method of questioning, the same will happen when we observe our mind. Stuck in Physicalism, it may happen that our practice is barren from the start. Thus the importance of having an open mind.
Scientifically, we don’t know the nature, origin or fate of consciousness. There’s a lot of intellectual sleights of hand when neuroscientists try to explain consciousness in term of neural correlates. If you still feel compelled to believe what they say regarding consciousness, search for the many logical flaws in their reasoning. They abound and are critical. See with what they come up to to solve the hard problem. Technical gibberish, filled with unsubstantiated claims, hope in the work of future scientists, that as far as we know haven't yet born. They ask you to take this on faith, but using the proper tone and language. You are being taken as fools. The fact is that for science, consciousness remains a huge mystery.
The actual theories of consciousness remind the epicycles used by medieval scholars to explain the movement of celestial bodies while trying to maintain the geocentric model. Their insistence upon it, when taken to the extreme, may lead to absurds like saying mental events or consciousness don't even exist. This was behaviorism at its best, in the 50's. But this position was so ridicule that even Skinner retracted such ideas later. There were a few years though, that most psychologists, especially in the USA, believed such nonsense! We thought it was gone, though. But with the arising of neurosciences, I fear we are once again walking towards a similar direction. Nowadays, the kind of experiences conducted in Psychology labs, apart the technological apparatus, remind me more and more of such dark days for the study of the mind (term nearly banned from any scientific discussion in those days). I even fear if Psychology doesn't shake off this neuroscientifc trend, there will come a day in which this branch of science may be seen as a minor curiosity, previous to the arising of the "all mighty neurosciences".
I'm sad, now.
