I realize I misread Eric B's last comment but regardless, my point still stands in that there's still feeling involved regarding Fi that extends beyond the feeling of emulating what others feel through empathy which I argue is still not so much a feeling as it is a logical process in many instances. It doesn't necessarily have to result in feeling anything particular in itself, I think.
It's not a logical process for me. When I was six or seven years old, I could see disappointment on the face of some old person on the Price Is Right on tv and feel sorry for them. I feel physically sick if someone hurts an animal, I can't even bear it. I knew when my grumpy, non-expressive ISTJ grandfather had sadness or despair in his eyes. All before puberty. Not a logical process.
In my teens, I became unduly self-absorbed about my own feelings (however, considering the life I've had, it's been in my best interest to self-examine) and would "wallow" in Feelings...like the beauty of something aesthetic, or I even had that "sadness is beautiful" trip at 15 or so (which I grew out of once I left home and got more life experience, sadness is not beautiful, but nostalgia or mild longing might be under certain circumstances, it's more of an honoring of what was, or what could be instead of actual "sadness.")
By young adulthood I was a defender of the weak and down trodden, but had also developed an unhealthy inferior Te-ish tone of bratty boot stomping indignation. I suddenly had clear, rational definable ethics starting around junior year of high school. Things which could be expressed in what could be called a slightly more logical manner.
But it still wasn't until my late twenties and early thirties that I began developing real perspective, and progressively sharpening my ethics more and more. I wonder if this is just a never ending process of moral maturity, especially given in my case, where I've suffered abuse, and therefore been distracted from the "normal" maturity process by my own need to self-heal.
Which is why Fi types can also be seen as so artistically or poetically or philosophically creative, because even when their ethics are not fully mature, or they are emotionally unhealthy, they can still move other people with their creations that strike some deep nerve in other people. And that's the power of Fi too, even when it's not expressed in definable rational ethics.
It's the power of feeling. But unlike the charisma to sway a crowd, it's more like dong things from such a deep and authentic place that it strikes the same nerve in others, and so it helps us all to grow, and hopefully also the person doing the creating, learning from the process.
Like my adventures in foruming.
Anyway, aside that, I rather not have a discussion about the exact nature of Fi with you specifically because you're an Fi dom because it tends to just result in a clusterfuck because there's also the Fi evaluative process involved where Fi types just... don't get other people's Fi. Because that person's Fi doesn't match up their view of Fi.
Seen it happen too much on PersC and I'm pretty sure you know what I'm referring to. Not because I don't mind talking about Fi but I wonder how fruitful it'd be.
I do.
