Let’s say that A is good, and that B is also good. (E.g. equality and freedom, or diversity and families, or current lives saved and rationality, or any of a huge number of things.) Let’s consider how the desire-for-A and the desire-for-B might avoid having their plans/goal-achievement disrupted by one another.
In principle, you could build a larger model that explains how to trade off between A and B — a model that subsumes A and B as special cases of a more general good. And then the A-desire and the B-desire could peacefully co-exist and share influence within this larger structure, without disrupting each others’ ability to predict-and-control, or to achieve their goals. (And thereby, they could both stably remain part of your psyche. Or part of your organization. Or part of your subcultural movement. Or part of your overarching civilization’s sense of moral decency. Or whatever. Without one part of your civilization’s sense of moral decency (or etc.) straining to pitch another part of that same sense of moral decency overboard.)
Building a larger model subsuming both the A-is-good and B-is-good models is hard, though. It requires a bunch of knowledge/wisdom/culture to kind a workable model of that sort. Especially if you want everybody to coordinate within the same larger model (so that the predict-and-control thing can keep working). A simpler thing you could attempt instead is to just ban desire B. Then desire-for-B won’t get in the way of your attempt to coordinate around achieving desire A. (Or, in more degenerate cases, it won’t get in the way of your attempt to coordinate around you-the-coordinator staying coordinating, with all specific goals mostly forgotten about.) This “just abolish desire B” thing is much simpler to design. So this simpler strategy (“disown and dissociate from one of the good things”) can be reinvented even in ignorance, and can also be shared/evangelized for pretty easily, without needing to share a whole culture.
Separately: once upon a time, there used to be a shared deep culture that gave all humans in a given tribe a whole bunch of shared assumptions about how everything fit together. In that context, it was easier to create/remember/invoke common scaffolds allowing A-desire and B-desire to work together without disrupting each others’ ability to do predictability-and-control. You did not have to build such scaffolds from scratch.
Printing presses and cities and travel/commerce/conversation between many different tribes, and individuals acquiring more tools for creating new thoughts/patterns/associations, and… social media… later made different people assume different things, or fewer things. It became extra-hard to create shared templates in which A-desire and B-desire can coordinate. And so we more often saw social movements / culture wars in which the teams (which each have some memory of some fragment of what’s good) are bent on destroying one another, lest one another destroy their ability to do prediction-and-control in preservation of their own fragment of what’s good. “Humpty Dumpty sat on a wall…”
(Because the ability to do the simpler “dissociate from desire B, ban desire B” move does not break down as quickly, with increasing cultural diversity/fragmentation, as the ability to do the more difficult “assimilate A and B into a common larger good” move.)
