I can tell you that reason plays a large role in ethics.[...] So I do not recognize the feeling function as being particularly about moral values. My own moral values are rooted in my sense that life, both mine and others, is worthwhile, and this is personal in the sense that it is deeply rooted in my experience of life. To put it another way, I do not value life simply because other people do; I value life because I recognize that it is good.
look at what you've said here though - you recognize that it is "good". "good" is a rather Fi determination in and of itself. Ti can determine pleasant, or sensible, or best, but it cannot give you the value judgment of fundamental goodness. that is Fi.
we associate Fi with ethics and values because Fi deals with tricky things that are difficult to approach with logic, like the nature of the human soul (assuming we have such a thing), whether the life of one human who is important to you is worth more than the lives of several humans who are not important to you, how we will respond to the death of a loved one who passes unexpectedly, whether there is a God or gods or not.
Anyway, you have told me how you understand Fi and Fe, but you have not told me what your experience of Fi is like. Is your understanding of Fi grounded in your experience? What is it like for you when you are using Fi?
okay... Fi... it's judging things on a subjective, context-filled basis. it's talking with a person and noting that something is "off" - that their overall body language and what they're saying don't match up. it's entering a room and picking up on an overall atmosphere - tense or relaxed. it's knowing when someone has "crossed the line" between being ignorant and deliberately antagonistic. it's reading a thread of posts and picking up on the emotional undertones. i like bjork, but the lyrics to human behavior really are not a good description of Fi - at least, not of Fi as understood by a dom/aux... maybe it works for Fi from a shadow function perspective.
here's a really Fi song --
YouTube - Defying Gravity Tony Awards 
elphaba, the witch, is Fi - glinda, the blonde, is definitely Fe dom...
so Fi is not actually always about experiencing emotion yourself, but it is about the ability to read and converse in emotion, if that makes sense. because Fi dom/aux are attuned to emotion, we tend to be especially aware of our own emotions - and it is a mistake to think that humans ever have bouts of time where we are emotionless - but that doesn't mean we are mired in the experience of emotion all the time. it simply means we have a better than usual awareness of our emotional states. i think of emotion like a thermometer - it tells me important things about my internal state. it tips me off to things i might miss otherwise. i feel irritated. why? because someone is treating me poorly in comparison with how they are treating others. and that is important. i feel sad. what should i do about this? reevaluate what is important to me. i feel content. awesome. i should make special note of what i'm doing right now and what the circumstances are so i can create this pleasant state again in the future.

Of course there is a practical and rational basis for ethics. However, the fine details of ethical reason isn't pure logic. I'm going to echo stalemate in saying that you are mistaken if you believe that Fe and Fi are not rational ethical processes. A T can be every bit as emotional as an F. It's not only about being emotional.

Fi has its own internal consistency... it's not logical, but it is
rational in the sense that it is consistent. in fact, that's really what Fi is about - assessing
subjective internal consistency.
OMGZ I love that Gee video with the Asian chicks. That music is just catchy as hell.
seriously!
Concerning Fi, they say, "Its goal is the fostering and protection of an intense inner emotional life, and so far as possible the outer fulfillment and realization of the inner ideal." Concerning Fe, they say, "Its goal is the formation and maintenance of easy and harmonious emotional relationships with other people." In describing both Fi and Fe, they refer to emotions. They also contrast them by calling Fi "deep and passionate rather than extensive" and Fe "extensive rather than deep." It is our emotions that can be deep and passionate, not our ideals and moral values. They also refer to Fe as "establishing warm sympathy" and Fi as being "too overpowering to be expressed at all" and appearing "cold to the point of indifference." It is not ideals and values that can feel overpowering; it is emotions. As understood by both Myers and Myers, Fe and Fi are different ways of using and managing emotions. Fe's tend to feel emotion empathically, while Fi's tend to feel emotion from deep inside. Fe's tend to synchronize their emotions with each other, while Fi's tend to feel passionate about their ideals. Inasmuch as Fe or Fi do affect moral decision making, Fe's tend to be moved by empathy for others, and Fi's tend to be motivated by deeply-held moral values. But morality is not the sole domain of feeling, and it is not all that feeling concerns itself with.
yes and no... the emphasis on emotion here is still way too strong. ideals and values
can be overpowering when we are too attached to them and refuse to see outside their paradigm, just as Fe social principles can be overpowering when we refuse to see outside those paradigms. the key is so much that while Fi and Fe do involve emotion you can have a Fi or Fe decision that is not
about emotion. for instance, me choosing whether i would rather wear a blue or red shirt today. well, maybe i feel the overall tone of being laid-back and fluid today, and i will probably go with blue.
so yes, that conjures all sorts of emotionally-tinged ideas like the association of blue and being calm and peaceful and relaxing and serene, and red of being fiery and passionate and angry and intense, but the decision itself did not involve me, personally, experiencing an overt emotional state. more like briefly shuffling through emotional associations to figure out what best matched my overall state of being. or maybe i'm just thinking about how i love the freedom of endless water and sky, and decide to go for blue. that's not really overtly emotional either, even though it does involve pleasant emotions. it's much more subtle. you cannot take emotion out of Fi or Fe, certainly, but the central idea of Fi and Fe is not emotion. it's more like a language Fi and Fe communicate with to establish internal (Fi) or external (Fe) subjective consistency.
