Ne vs. Se
Ne sees and finds patterns and connections within and between information processed it tends to see "everything in every thing".
Se processes information Se sees what it sees, in a literal sense.
Ni vs. Si
Ni takes in input, integrates it, catalogs it, and through some sort of divination receives a highly perceptually-based introspection into the universe, that is not visually seen, per se, but that is Known and strongly believed to be the essence/core of the transcendent, it can channel itself into the universe, perhaps it is a channel, a receptacle, a vessel, it knows the infinite, better yet, it knows the essence within the infinite, and it concerns itself with the eternal Truth, it sees beyond itself, it feels connected to its perceived universe, a part of of the infinite, and this perceived universe is representational of everything that it sees as essentially true and transcendent.
Si collects and archives salient information, it holds on to its past experiences and memories to understand why the world is the way it is, and why things are the way they are, patterns emerge, correlations and causations are noted, new experiences make sense when you analyze past similar situations, what happened then? Why did it happen, how did you respond? Did your response yield positive gains? Si, the past foretells the future, history repeats itself, remember the lessons past experiences have taught you, never forget, your past defined you, your future will benefit from what you've stored and remembered, Si finds solace in engaging in experiences that are comfortable and pleasing. It will do everything in its power to avoid or overcome unwanted and uncomfortable experiences, it seeks comfort, it desires to only deal with comfortable situations, where it feels familiar, and at ease with its surroundings.
Te vs. Fe
Te cares not for precision, it cares for efficiency, time is of the essence, it cuts through what it perceives as bullshit, it's about the bottom line, getting shit done, executing action.
Fe cares for localized harmony, it wants its community to be happy and harmonious, it will do whatever is necessary to maintain this localized harmony, it is innately metamorphic, and self-sacrificing, constantly changing to make things better, to make others happy, Fe is validated, manipulated by, and manipulates the community that it cares so much for, its identity is formed and based by those they care about.
Ti vs. Fi
Ti sees chaos, flagrant errors/holes everywhere, human-based errors, and this motivates it to define and constantly refine a model of thought that, within its own realm, is seamlessly precise, it is a linear way of organizing the chaos, of sifting through information and testing whether or not an idea is ridiculous, difficult, challenging, or retarded. It sifts, finds, defines, and refines, what makes sense and why, what doesn't make sense and why, Ti wants to find some kind of order and inherent logic within the universe.
Fi first begins as a journey of understanding one's self objectively, it seeks to understand itself, it seeks to acquire self-awareness, Fi seeks and finds one's personal identity, who they are, why they are the way they are and why they do the things they do, then they use the same methodology on other human beings, they seek to understand the essence of human behavior, flawed and all, it puts itself in various human circumstances and puts a value of importance to the circumstance itself, and then judges the action(s) taken in each of these varied circumstances as categorically Wrong or Right, Fi judges itself the same way it judges others, no special treatment, Fi thinks, if I was there, as that person, within the same circumstance, how would I act? If I were being true to my "Self", acting, no *being* authentic, truthful, sincere, and honest to myself and others, in spite of my and other's egos, accepting what's happening and what it's feeling as they truly are, being self-aware and humble, being self-aware and courageous, doing what feels intrinsically and categorically Right despite the fact that often by doing so, friction will ensue. Fi needs to feel and understand what's categorically Right and what's categorically Wrong, universally and independently.
