Penumbra
All your arguments stem from the premise that intelligence emerges from the physical brain. Which means that we are
intelligent/conscious material product. OK?
Now, tell us, whether you, with your rational senses have seen any
conscious physical product or not? ( Kindly leave aside speculations of AI). Life is not just the measurable material -- it is unique and there is no evidence of any
'conscious material product'. Yet you insist that we are 'conscious physical products' and so attempt to apply the concepts of 'material sciences' to that which is evidently not similar to other materials. How rational is that? What rational evidence you can provide for your own premise?
You insist that intelligence with which you measure everything should itself be measurable/visible/graspable. How rational is that? To me it is the height of irrationality. Have you seen any product to unravel its own cause?
You equate correlation between brain structure (physical) to events (physically measured or observed) and translate the corelation as the cause of consciousness, which is evidently non-material. How rational is that? Both the observations of the brain structures and the phenomena are representational and subjective. You are linking two representations as cause and effects without considering the conscious subject. How rational is that?
FURTHER, Just a moment's contemplation on one's "I" reveals that the awareness is not graspable object.:yes: Moreover, that the intelligence is given and that it never ceases to be the underlying factor for the universe to be known is not even acknowledged by so called rationalists.
