so-o-o-o...
we have Ti users in a tizzy about Te objectivity. This has revealed the presence of a value, "objectivity". Interestingly, I think we might even be able to say how "true" comes to exist now. It's this "objectivity". Objectivity is the exclusion of external feeling compromises from decision-making cognition. Worked to it's fullest extreme, whatever is marked by this objectivity can also be called "true". Strangely, the Ti people are (or were) pointing at Fi as a containment in a Te judgment system, mostly because it's semi-conscious and directs "truth" judgments by introducing a subjective, divisive, personal focus into decisioneering. And I say "strangely" because though Fi should be a nightmarish problem for Ti, it's the practice of Te that's really making the waves. It functions just as Fe does, taking world cues and making stipulations. It, like Fe, is all over the place, slatternly blessing this or that situation with a truth value if it takes a fancy. Ti types seem to think this wanton splattering of the world with "truth" is a result of subjective choices when what subjective choices are more likely to urge is caution in the areas we care about. If "true" actually is valued, or more exactly if the truth process actually is valued, then when we care about something, we'll move to a heightened awareness of when and where we're performing adequately. If it's important that we be part of some situation, it'll be important that we get our involvement right...
That's to say, [big leap] there is some conceptual connection between Te and Fi. Both are judgment systems, but neither can function without the other. In simple terms (because I haven't discovered the complex terms yet), you can't care about mapping the external world unless you care about something at all. It's something about not being able to develop a truth without first caring about truth per se, and something about not being able to conclude what's right and wrong for yourself without first wanting to know what's real in the world.
So how does it work for Ti and Fe?
You can't care for things of the external world unless you think? To feel in accordance with external world cues never happens unless somewhere you are able to judge categorical differences without reference to emotion?
Note: these are conceptual connections, not conscious processes. The idea is Fe evaluations will never exist unless held within their judgment is some reference to basic distinctions between terminological categories... or whatever the hell it is Ti does at its core.
And why? Because Fe, like Te, is a judgment that reflects the world. Without an i aspect present to influence decision, in fact to create decision, then these judgments would be little more than daily records of what was seen for at least as long as we can remember it.
There is some more thought to do on this scheme and it may perhaps not have been done yet elsewhere. It's perhaps some attempt to explicate not just that but also how rejected consciousness is present unconsciously in preferred consciousness. Consider yourself blessed to be part of a work in progress.
