Nietzsche also hinted at the way moral rules get enforced: you aren't ashamed of your own thoughts, only of someone finding out about them. Basically, this is fear of being exposed.
In our (the Western) society, this is most true for sexual and/or violent thoughts, as well as anti-government or anti-religious thoughts. Particularly when it comes to sexual thoughts, I cannot find a reason for holding back any of them.
You are not only ashamed of getting caught. You INTERNALIZE the shame. You BELIEVE you are no good. I was just watching a youtube video that had a clip of a "youth minister" in a charismatic church getting a room full of what looked like 10-13 year olds in tears and on their knees talking about how they had disappointed jesus with their behavior, exhorting them that "YOU know what you must repent. Say it out loud."
If only we could keep the external external. If you have managed that you are way ahead. Don't miss what is happening with those who haven't managed.
