Primary Ti doesnt match up with Primary Fi in the OP. I like what you wrote, but more with thought in regards to Ti.
This lines up with what you think of primary Fi
Huh? Fi is a judging function, just like Ti, so they are both used to understand and know and place an order of sorts. Fi is used in a values, emotional, feeling way. Ti is used in a principles, rational, analytical way.
Something tells me I'm not following your point. Was your point directed toward me or the OP. I'm confused...
