In order to use Fi one must assume Fe. I am ENFP with a stronger Ti than Te which is why I have difficulty in arguments. I have difficulty explaining myself as most of my arguments are deeply internal and come out in broad based generalizations that stir quarrels. I suppose this is why I identify with Jesus so much. He seemed to speak in a similar fashion. Although more poetically and, I believe, probably after having already learned the answer to what he was discussing. Most the time when ENFPs talk we are searching for an answer with words.
