Being could not exist in human brains without non-Being. First, the split is required. Subjugation follows. Non-Being is the worst. The self to the other, the here to the there, the us to the them. Whatever's inside will win, inside, at least, and outside, where possible, even as it's all a construct.
This is the foundation of worldviews. Lifetimes of associations bound tight, "inside" bound up with "sanity" and every other positively tinted bit of verbiage. (Does "positive" even have a meaning that transcends the logic of inside and outside? Can the word signify anything other than inside?)
And when it breaks down, when the inside is shown to be the same as the outside, this is when apologetics happens, when irrelevant distinctions are invented to hold the line. A student today tried to explain how China is particularly imperialist. I said, "how about Okinawa?" He said China's history has been a roller coaster ride with one regime violently replacing the next. I asked him if there was any fighting in the transition from Edo to Meiji. It's different because of blah and blah. No, it's not, I said. We could back and forth forever without him giving up his foundational assumptions.
Speaking of holding the line, God retreated from the forest to Mount Olympus to the heavens to another dimension. He retreated but it worked. He stayed alive, though barely. Politicians and other abusers claim good results but, under pressure, retreat to good intentions, with some success.
