M. Scott Peck writes about neuroses versus character disorders—taking too much responsibility versus taking too little. A person with neurosis tries to fix other people's problems. A person with a character disorder doesn't even try to fix their own!
What if this relates to whether a person experiences their guiding voices as inside or outside themself?
The inside/outside question clearly relates to Myers/Briggs intuitive/sensing discussion—intuitive deals with interpreting information into abstract patterns and meaning (inside), sensing deals with physical facts and material reality (outside)
Is it too much of a stretch, then, to say that someone taking too much responsibility (a neurotic) might be more likely to take too much responsibility for the ownership of guiding voices—to hear those voices as coming from within—where a person taking too little responsibility (someone character disordered) might be more likely to take too little responsibility for the ownership of guiding voices—to hear those voices as coming from without?
