I can readily articulate the differences between various cognitive functions. For example, I can tell you the main differences between Fe and Fi. Or Ne and Ni. But I have a hard time articulating the overarching differences between F functions and T functions.
I want to hear your guys' explanations of the differences between F and T. (Even better is if this explanation comes from someone fluent in JCFs (Jungian Cognitive Functions).) I've read a gazillion MBTI explanations of the difference between F and T. But after adopting the JCF paradigm, these MBTI explanations seem overly simplistic to me.
What do Fe and Fi have in common that they don't share with either Te or Ti (and vice versa)?
