You say it communicates with you and can speak for itself.
Not only do I claim that, but also make the assumption that you are able to replicate this too.
The aspect of the self I am referring to (which can be communicated with scientifically) can
speak for itself, and in a manner the isn't restricted to being 'avoiceinthehead'.
As a scientist I know that attempting to collect data by introspection is not, on the face of it, a scientific endeavour, being subjective, unverifiable, and not independently replicable.
The data you can collect is not based on the process of introspective mulling but of actual use of a measurable device in order to get physical results.
While it is subjective in that this larger part of your total self is directly related to you - (that part of yourself you are not aware of in relation to that part that you are aware of), the data is variable
in that context and the
process is certainly independently able to be replicated. (by anyone - not just scientists).
The only 'problem' with it is that not too many individuals can be found who have that much curiosity, let alone spare time to dedicate to finding out.
That does not in itself prove the claim false. It more goes to show that it is not the science but the scientists/any intelligent persons who chose not to go there and do the hard yak.
For a number of reasons it does not garner interest.
For some it would be just a matter of priorities. For others it may be a fear of what might be found/discovered, and still for others, just a case of superstition, or their religion forbids such things and still others, simply they have not heard so do not know.
'Whatever' the reason the individual might chose for not going there, (or in some cases have no choice because going there has not been presented as an option) 'there can indeed be gone to, and thus is relevant to any argument pertaining to things of the subject of Consciousness.
Q: Where is 'Going There?'
A: To that aspect of everyone which can speak for itself as to 'what it is.'
Therefore anyone who argues in a manner which involves telling themselves and others 'what it is' and who has not gone there and allowed 'what it is' to speak for itself, may be speaking out of turn, and falsely.
I don't have any sense of internally communing with 'others' or an 'unknown me', so that path isn't available.
That only has everything to do with your personal boundaries which define your self identification (at this time) - these set up a metaphorical 'wall' which allows your dominant identity to have no 'sense' of the larger self. The tunnel through that wall is the path which you would have to make the decision to build in order to bridge this connection. I can 'tip' you that one half of that bridge connection is already built and ready for coupling.
The coupling process is delicate.
My subconscious doesn't manifest itself in the way you describe.
What would you think it should do in order to prove it can communicate with you
and tell you what it actually is?
