I was just out driving having a clove listening to some techno and I had a cool vision regarding Fi and Ti...
Fi cannot accept that the subjective self has no purpose and is just a machine, things wich feel cannot be just machines.
Ti cannot accept that it has less or more value than another human, human being defined as an object that thinks.
After having realized this then intuiting about it I also realized that when I intuite heavily I touch my face and hair, and then realized that this might be Si coming out as a result of Ne. This part is just hypothesis for now because I have only myself to confirm this with.
