We haven't seen Satine on this thread yet. I'm looking forward to her input. I think she has a very good handle on Fe and Fi. This is a previous Satine post that is so on point regarding the Fe/Fi and Te/Ti part of the discussion... and is so well written that I felt it appropriate to repost here.
Sometimes Fi is better to use in a particular situation than Fe. And sometimes it's the other way around. This post made a lot of Fe come into focus for me... because I understand my Te pretty well. I think she's right that Fe is very practical. But it should also be said that sometimes Fe pays a heavy price... too heavy... for its pragmatism.
