Description of Fe from "Dual Nature of Man" by A. AugustaBlack (extroverted) ethics Fe
Perceives information about processes taking place in objects — first of all, emotional processes that are taking place in people, their excitation or subduedness, and their moods. This perceptual element implies the ability to know what excites people, and what suppresses them. It defines a person's ability or inability to control his emotional state, and also the emotional states of other people.
When this element is in the leading position, the individual has the innate ability to induce or convey his moods to others and energize people with his emotions. He is able to activate the psychological/spiritual lives of other people and their emotional readiness for action. You might say that such a person has the ability to infect others with his moods and tends to impose on others the emotional states that he considers beneficial for their life activities.
What people usually call emotions or a person's display of emotions is neither more nor less than a form of letting out this internal excitation directly, almost without expending it in muscle activity. A cheerful person who laughs releases an emotional charge and inner excitation through certain movements of the muscles of the face and body. This might be a means for reducing overexcitement, when inner exertion cannot be used for the activity it was intended for. But it can also be a conscious method of conveying one's excitement/agitation to others — inducing one's internal excitement/agitation in the psyches of other people. Anger, for example, is also a way of reducing overexcitement, but it is usually directed not at arousing others emotionally, but at emotionally suppressing and depleting them, at lowering their activity level, or at strictly channeling their activity.
Wikisocion description of Fe
Extroverted ethics (Fe) is an extroverted, rational, and dynamic information element. It is also called Fe, E, the ethics of emotions, or black ethics.
Fe is generally associated with the ability to recognize and convey (i.e. make others experience) passions, moods, and emotional states, generate excitement, liveliness, and feelings, get emotionally involved in activities and emotionally involve others, recognize and describe emotional interaction between people and groups, and build a sense of community and emotional unity.
Types that value Fe like creating a visible atmosphere of camaraderie with other people. They enjoy a loose atmosphere where anything goes, where people don't have to watch too carefully what they say for fear of offending others. This means these types try not to be too thin-skinned, taking jokes with a grain of salt. However, they are very conscious of the fact that the way something is said is very important to how it will be received, so they tend to add emphasis, embellishments, and exaggerations here and there to keep people engaged. The best way to say something is highly dependent on the situation and the implied purpose of the exchange, so of course levity is not appropriate in some situations.
Even after explosive arguments, these types find it hard to hold grudges, and can tolerate people they in principle don't like, as long as the situation is primarily social and doesn't require too close contact. They prefer misgivings to be out in the open; they believe that the silent treatment is one of the worst things you can do to a person, and only aggravates the underlying problem.
