My understanding of the Fi/Fe attitudes is slightly different than what was described. Introverted feeling leans towards a sympathetic attitude (ENFP) and extraverted feeling leans towards an empathetic attitude (ENTP).
Example: I understand how terrible you feel about your crummy boss [empathy], but I have no sympathy for you. Logically, you have the power to change your crap situation. That means you're probably not going to hear many coddling words from an ENTP (not seriously); like,
"awwww, you poor thing, let it all out.. that jerk" [sympathy]. That's an Fi attitude.
Here's a brief explanation on the difference between empathy and sympathy that I posted awhile back:
There have been long Fi/Fe thread battles over this one... I really don't think Fi nor Fe has a monopoly on either empathy or sympathy. Usually the reverse is implied by people though...
Personally, I am more inclined to empathize than sympathize. I easily imagine another's pain, even if I have never experienced it myself, but I'm less inclined to offer sympathetic words because I feel awkward. Often this simply becomes info I file away to refine my understanding of human nature & by extension my ideals.
I'm not sure if Fi in the aux position is quite the same...it seems they are more open to having their feelings affected by others, due to being Ne-dom.
And I'd think your experience of Fe in the tertiary is likely not to sound familiar to an FJ, who probably would more readily identify as empathetic
and sympathetic.
This definition of empathy is more pertinent to what I mean:
the intellectual identification with or vicarious experiencing of the feelings, thoughts, or attitudes of another.
It doesn't require the person to have first-hand experience. I've heard other Fi-dom say (and I can relate) that it feels as if you simulate a person in your head, and experience something close to as they would, so that you know their feeling vividly, but this also does NOT affect your own feelings (both rational & emotional).
Jung also actually says that Fi is shut off from appropriate forms of sympathy, due to its intense & self-protective nature & requiring accurate/authentic modes of expression, and as such it often comes out in extravagant, unrelated forms unexpectedly or in secretive, private forms, like poetry, art or religious activity.
From Jung's
Psychological Types, under The Introverted Feeling Type:
Jung said:
...their feelings are intensive rather than extensive. They develop in depth. While an extensive feeling of sympathy [Fe] can express itself in appropriate words and deeds, and thus quickly gets back to normal again, an intensive sympathy [Fi], being shut off from every means of expression, gains a passionate depth.....It may, perhaps, break out in some extravagant form, leading to some astounding act of an almost heroic character.... To the outside world, or to the blind eyes of the extravert, this intensive sympathy looks like coldness, because it usually does nothing visible, and an extraverted consciousness is unable to believe in invisible forces.
