I think people tend to see Ti as subjective, basically because the basic foundations and premises are internally set.
I don't fully understand it, but I am willing to admit that.
I could be wrong, but I do think both Fi and Ti both work from the concept of "If I know this to be true, then X Y Z therotically are true too"
Both functions are algorythms ever refining and redefining. Both distill outside input so the essence of "truth" is revealed. The material is different and thusly the equipment doing the refining is different.
I'm not sure where I'm going with this.....but it seemed good.
I don't necessarily think Fe as more objective, than Fi either. I always think of my mother when she'd say "I'm cold, put on a jumper." She didn't ask me, if I was cold, she assumed because she was cold, I was too. Again I'm not sure where I'm going with this, I'm just grabbing at strands of thought as I read this thread.
Fi looks inherently selfish, because we act upon internal determinants, but Fe can be selfish too by imposing thier feelings onto to others without asking. I'm just repeating sentiments expressed already here.
I'm thinking what irritates Fe users the most (and I'm basing this this off the feelings I get round Ti-users) is the fact we seem like we are hair splitting our feelings and our observations, and the Fe-users feel like they are about to get nose bleeds, because the answer right there already, what actions that need to be taken are already dictated, and it is just more efficent do it that way, rather trying to redefine what's already in place. Am I on the right track?
So basically what irrates Fe users about Fi's grand declarations of Universal emotional truths isn't the truths themselves, but that we have completely ignored standard operation procedures (otherwise known as social graces, or what ever more appropriate word is applicable), declared our theories as fact without subjecting them to testing and peer review.
The Fi users get upset when our grand theory of truth gets ignored, because using our own brand logic we've thought this through, deeply and examined for flaws (or unauthenticity.) Our theory is air tight, but we need people to accept our idea, so we can go out and test it and make the appropriate changes to the standard operating procedures, so they aren't so restrictive, but the truth is so obvious to us we don't understand why no one else can see it too.
Am I on the right track?
