“opposite functions”

Before we go further we must know we need to know what functions work together, what functions don't, what can't and how. Most schools of taught would agree that what I like to callcancel each other out, that is you can’t use them at the same time. Arguments could be made that you could reach a balance (so it’s either 78% one and 22% the other or 50/50 or 60/40 etc.) or that you can switch between them very fast though. These functions I call “opposite” are of the same attitude (both introverted or extraverted) and on the opposite end of their axis. Because of the same (i)rationality and attitude, a “fighting relationship” is between the two elements of the pairs, one struggles to take control of the other one. The relationship between them is one that works similarly, has the same starting point but because of opposite S/N or T/F reasons differently, thus coming to the conclusion that they have the same start point but opposite destinations. Having opposite destinations would mean you would have to choose one, you can’t use both at the same time completely and having the same “Start point” would make them fight for the same place in your cognition.
