How will you know who is speaking with you when you hear the inner voice which everybody seems to think it is your mind which is speaking from within. You cannot see the inner voice. So how will you objectively base your deduction who is speaking with you. What is the proof of this, if any, allowing for the fact you cannot see human mind. Physical evidence of brain patterns give electrical and magnetic influences with brain patterns from which scientists deduce that human brain is the mind. This is a big mistake.
