ZMan captures Lewis Carroll.
After defining the terms 'partisan' and 'objectivist,' (Left, Right) he observes:
...The partisans are an ends justifies the means mode of thought. They are unconstrained by rules or convention. In fact, they are not limited by what they said last week, as last week was a different time with different goals. In a world where winning is the only thing that matters, everything else bends to serve that end. If being seen as on the science is useful in the moment, they love science. If treating science like magic is useful next week, then next week they will mock science....
It's the formulation of Carroll's Queen of Hearts. Carroll wasn't stupid; emotion rules the partisan and the heart, after all.
ZMan is not an optimist.
...For the most part, though, this willingness to transcend facts, and even reality in some cases, is a great advantage in a democracy. Politics in a democracy is immediate, rather than deliberative, so that first impression counts for a lot. If in the fullness of time those initial arguments are found to be full of lies or simply wrong, it does not matter as everyone is onto the next thing....
See, e.g., the transition from "Climate Change" to "PANDEMIC WE ALL DIE!!!"
As to 'politics........first impression', look at how well Biden is doing, where HIS 'first impression' is about 50 years old!
