As for Ne vs Ni, let me relate a long discussion I had last night IRL with an ENFP of our mutual acquaintance. She was busily digesting the contents of several books, including "A Course In Miracles," "The Four Agreements" and the "Tao Te Ching." Curious, I pointed out a section of the Tao and asked what she thought. I expected she'd take 15-30 minutes going over it and tell me what thoughts the text invoked.
She read it in about 60 seconds and said, "Benevolent detachment."
I just looked at her funny. "Um, sort of, but there's a lot more to it, than that."
"It's all just benevolent detachment. You see it here, and in the Four Agreements and in Buddhism and several other religions. You just split off yourself from the real world, and then you see the truth."
"Um, no. It really isn't just that," I replied. "There are so many ideas here, in this section of the Tao. For example, the 'Practice not-doing, and everything will fall into place.' What does that mean to you?"
As Ne, she is pulling ideas in from all over, and synthesizing them into a single concrete understanding, trying to find the unifying truth in all of them.
As Ni, I chose that particular line about "Practice not-doing," because that is exactly
what I do when I think. When I don't try
to think, my thinking falls into place. If I try to think hard, it just doesn't. By "not-thinking," I get my best thinking done. And this attitude works in other aspects of one's life.
E.g., a dancer dances (Se), but doesn't actually "think" about dancing, doesn't actually "try" to dance, but she just dances, seemingly effortlessly; the dancer is
the dance. If she were trying to dance, or thinking hard about dancing, you'd see the flaws. It would look wrong. Instead, she reaches a level of understanding/skill that she is "not-dancing", and thus dances very well. (I point out this Se example to show how it is quite compatible with the Ni perspective.)
Yet Ne glosses all of this over, looking for its version of the "underlying pattern" and gets "benevolent detachment."
I hope this helps you with your self-insights, Marm, and gives the rest of your a better understanding of what Ni "really is."
