That's interesting...If it's done in such a calculating way, why is it not Te? I mean, suppose a person says, "I want to accomplish X; and to get there, based on knowledge, etc., I see that doing Y will be the most efficient and effective way to accomplish it." Now that, phrased with the word "doing," sounds kind of Te; but if we substitute "saying" instead of "doing," all of the sudden it becomes Fe?
Now, to reconcile this with what I see as the intent of what you're saying....It seems to me perhaps that Fe involves so many disparate calculations related to communication and people's likely reactions that they can no longer be handled by Te, but must be guided by Ti. Now that's an interesting thing too. But you see that there must be a finer, or more precise way of distinguishing the two here....Surely a way of reasoning that's Te-like can't become Fe merely because it's logic related to situations involving communicating with people, as opposed to logic related to some other area (?).
