i can see how shame and guilt could potentially be a fe/fi cognition
shame is a violation of cultural or social values (more external)
guilt feelings arise when one violates their internal values
atleast this is according to Ruth Benedict (cultural anthropologist)
Some might feel like shame shouldn't exist, but it doesn't really matter because it does exist, frequently within the human condition. It's really no different than saying sadness, anxiety, irritability, guilt or any other more negative emotion shouldn't exist. In which case, we might want to look at how some of these more negative feelings can bring forth positive creation, growth, or if they have their very own inherent value.
Anyhow, I think that what you are getting at Elfboy, is that people should understand that they can avoid darker feelings by changing their perception and judgement of external standards and where they fall into that. I have thought alot about this too, and found it helpful for me many times.. but the fact remains that we are very connected species and some external standards are bound to weigh on our conscience.
Do you think someone that molests children, and finds that act perfectly in alignment with internal values, should be ashamed? I realize this is an extreme example, but I am curious.
