...could be. The three brains are a 'fact' of life (supported by many, in the same 'trust' as peer review would provide). Theism (in depth - and as far as I know) 'allows' for communication at that level. This is a form of meditation, to let the images come, and from there let them 'stew' until they 'create' something for us. To communicate 'with' these minds is the basis of theology, 3 - the triune nature of reality (so to speak)
I think I understood what you meant, if not, please let me know.
As promised I have thought about this idea, and I am afraid I have to label it as special pleading. 'This view is exempt from logic and standards of reason because those very standards prevent us from seeing it.' Keep in mind special pleading isn't necessarily wrong, not if you can demonstrate the request for special treatment is valid.
So I would have to ask...
Can you provide examples of this trans-brainial communication? What are the qualities theism teaches that allow for this? Are those qualities unique to theism? IOW, is belief in God necessarily the responsible out come? If someone masters this communication, what external, applicable knowledge do they gain? Will this knowledge compare coherently and consistently with other masters of the technique? If not, then what you seem to be saying is that a person can find personal support for their ideas of God if they look deep enough inside themselves and disregard everything they have learned about standards for accepting knowledge in all other areas of their life. <-- This is a statement I would have to agree with.
And yes I realize I am now asking for substantiation using the standards of reason. I'm not sure how else we can distinguish fantasy from reality? What other way do we have to differentiate theological answers from brain-cum? Fixation on this idea has to be a result of some sort of reasoning, or else it is simply random and carries no more weight than other random ideas.
It would seem fair to say that a vast number of believers do not even have a concept of what you are proposing. Are these people erroneous in their belief? Are you saying that most people know god falsely? I am having trouble understanding how this reinforces your belief in Christ.
