Sometimes the way Jim presents it makes it sound like there's this thing at the heart of the story causing problems, but you can't see it in its entirety. You can only see part of it from any one perspective so the best you can do is look at all four perspectives at once to see this thing and guess at what it is. And that may be right, he's certainly the one to go to for advice on that over me. But the way it makes sense to me is not to think that there's some thing or event or idea such as "birth" or "death" or some aspect of the human condition at the center of the story creating problems, but instead to just look at the inequity--that is, the imbalance between Knowledge, Thought, Ability, and Desire--as the thing at the center of the story causing problems. So rather than saying that some aspect of the inequity at the heart of the story is an "alien threat", you might say the inequity at the heart of the story is too much Universe, not enough Mind. But you'd have to do that for four area instead of just the two. So if there's no problem, no matter where you stand, K, T, A, and D would all look balanced. But then once there's a problem, you might say "If I stand at K and They stand at A, then the problem looks like way too much K, way too little A, not quite enough T, and a little too much D". Or at least something to that effect. And in that way the inequity that you're describing just is the imbalance between processes, the difference in level between K and T and A and D. The subject of the inequity could be conveyed as Universe of Aliens, Mind of Aliens, etc, or it could be conveyed as Universe of Aliens, Mind of Pirates or something completely unrelated. Doesn't really matter what the subject is, it matters where the imbalance of the elements falls.
