So this is just something I've been curious about, and I'm interested in everyone's thoughts. I've always struggled with my 8th function, introverted Feeling, and I've always wanted to know why. But it came to me the other day... is the reason we struggle with our 8th function because our Aspirational role (4th function)?
For instance, whenever I try to use Fi, i.e. try to figure out what's important to me or has value to me and use this to make decisions, it works out at first.... but then when people I care about express disappointment/anger over my decision, I start rethinking the decisions/values I made with Fi and start flip-flopping because I want to make them happy (Fe). I don't have a specific example right now, but I'll come back to it. Does that sound like Fe blocking Fi, or is that just me?
I think this could work the other way around too. Take ETJs... Their aspirational role is Fi and their devilish role is Fe. Maybe when they want to use Fe to make decisions regarding the people around them, Fi kicks in and reprimands them for contradicting their personal values. Or for ENPs, when they try to make a decision in the moment using Se, Si kicks in and remembers how things always have been and uses that as a guideline instead.
So anyways... just a few thoughts. What do y'all think?
