If the exception to the rule doesn't understand themselves as such, it can lead to chaos on either (or both) a personal or societal level, specifically when in the capacity of lawmakers.
Laws made by exceptions with only "the exception" in mind will be crafted like a fish net with a large hole in the netting. The most egregious, biggest fish will still be caught, but so much of what would constitute the normal catch will just pass through. Without these everyday catches, entropy catches up, day by day gaining ground.
Of course, "the rule" even more often misunderstands itself as "the exception." Pride is easier to attain than humility; thus, as a rule, “the rule” will be more prideful than the exception. On the other hand, the exceptions will certainly have more to be prideful about, and this predisposes them to a kind of modesty. Excessive pride is a psychological defense mechanism of resentment, born of a deeper and usually subconscious understanding that one is, in fact, "the rule."
Be that as it may, “the rule”, by nature, admits of no exceptions, while exceptions admit of the rule - but at a certain point in their life cycle, exceptions tend to cease admitting (i.e., believing) in themselves. The latter-day exception then fully learns pride by dressing itself up as "the rule," a king kneeling before the people proclaiming himself "the first servant among servants," etc.
All this prepares the ground for the takeover of "the rule." And wherever "the rule" rules, its foremost political project is the tearing down of the exception, sabotaging the evidence, finally, of the exceptional existing at all. "Social blasphemy," "false gods of man" are the charges laid at the feet of any would-be distinguisher.
Chaos is the rule; order is the exception. All else flows from this. This is a crucial understanding for anyone wanting to understand the stakes. All benefit to some degree from order, but this benefit is not uniform. While, once fully in its grip, all suffer equally from chaos. Its advocates draw our focus to the "equally" of the preceding sentence and would have us continue to forget the suffering necessarily in conjunction with it, only to be relearned as a rule (and thanks to it).
