Yes, it does. I'm going to come back tomorrow afternoon and revive this thread, because I'm simply too tired to type myself.
Ni basically deals with the past and the present, from what I just read.
Ne deals with all of the possibilities in order to eventually form a conclusion.
Fi basically enforces an internal ethical code.
Fe projects the users consciousness upon other people in order to empathize with them. Otherwise known as compassion.
Those are extremely oversimplified/rather inaccurate definitions.
Ne - Ne is concerned with exploring new patterns and combinations in the external world, replacing what is with what might be. Ne seeks to change and redefine everything about the external world approach; it most often manifests itself in the form of an attitude along the lines of: "If we've done it this way before, that's a great reason to try it a different way this time." Ne is the process of leaping in on a whim and exploring the theoretical implications of every system it can find in the outer world, just for the sake of discovery--"What does this complex series of buttons do?"
The downside is that Ne requires external validation for its ideas. It wants to show others the connections and the discoveries that it's made and for others to understand them too. (For instance, Ne poets and songwriters will typically write distinctly solvable patterns and puzzles into their lyrics, wanting the reader/listener to connect the dots and discover the meaning in the subtext. They WANT you to get it they way they do.)
Ni - Ni also involves a redefinition of perspective, but only in terms of one's own personal interpretation of it. Ni tries to back up one step further and discover the flaws it in its own perceptive approach--how might the assumptions I am making based on my perceptions be misleading or incomplete?
Ni requires no external validation for its ideas and discoveries because it never interacts directly with the external world. Ni doesn't really care whether or not you understand--it reasons, "I can see the connections in my head and it makes sense to me, and since you are not me and cannot experience reality in just the way I do, you won't get it and I gain nothing from attempting to explain to you."
Unfortunately, given the total lack of emphasis on the external world's approval, Ni gone awry results in a lot of bizarre conspiracy theories because it's convinced that everything is entirely in how you look at it. Ni is not very good at picking up on abstract patterns in the external world, as it doesn't work well with the external world at all--Ni users (NJ types) leave that up to Te or Fe.
To Ni, truth is but a frame of reference. There is no objective truth until an external goal or set of rules has been defined: If there was, how would we know our perception of it was not deceiving us?
Often Ne is so busy playing with patterns and toying around with the formula to create something
new that it overemphasizes originality/creativity at the cost of other values which may be more important.
Ni writers don't typically care whether or not you or anyone else can pick up the exact meaning in their words--they're not interested in any external validation of their perceptions, so often their writing will be impossibly abstruse and often totally meaningless to anyone else who doesn't share that Ni user's exact perspective. But Ni doesn't
care if anyone else gets it.
Ne may forget to ask: "Why do I
need to solve this puzzle/win this game/complete this pattern/derive this formula? What purpose will this actually serve and how might my perception of its importance be skewed?" These are questions best answered by Ni, a function in which most P types are tragically lacking.
It's often said that Ne is so far outside the box that it doesn't even know where the box is. Ni is standing just outside the box and looking back in on it, wondering about why the box is set up the way it is and what that might imply about the people who put it there. To Ni, Ne users often just seem like pattern monkeys--very useful for generating new and unique combinations of ideas, but not very good at seeing the ultimate big picture.
I'll get to Fe and Fi later; I think I've written some older posts on them which I might be able to find.
