Well I disagree that “we can’t find it”. I think the inability to find the self is a result of the limitations of empiricism, whereas dialectical and materialist analysis has no problem locating the self within the changing relationships that define the individual, history and nature in context of each other.
And this is what empiricism really fails at: its great at defining an object, defining the parameters that constitute it, and isolating it as a subject of study, but absolutely falls short at being able to identify the relationships between “things” or the historic circumstances that give rise to them.
As observers, an over-reliance on one theory of knowledge, or epistemology, verges on the kind of ideological blindness usually associated with fringe fundamentalism. We wouldnt us a ratchet to hammer a nail, why would we insist that a single epistemic “tool” is the only one that is capable of determining truth?
Honestly I probably agreed with you more some years ago before reading Sam Harris’s Free Will, which was so bad it set me on a very different path of inquiry.
I agree with a lot of your analysis, but I think a lot of these conclusions are highly contingent on historical circumstance. For example, I think Trump is a lot more unpopular than the current narrative regarding Trump. The Dems do not want to be so wrong about Trump’s chance of winning as they were in 2016. A dynamic that could play out in this election is that many of the groups you identified (and were right to do so) feel so threatened by a Trump presidency (in part because of Dems successful and good organizing against him) causes those groups to unite and keep him out of office. This could lead to a split between the pragmatic republican movement concerned with maintaining the status quo, and the pro-Trump MAGA militants who are not as homogenous of a group as may first appear.
But feel free to “neener neener” about it if I end up being wrong in a few hours. My point is, things change, a disparate group of different interests can unite into an unbreakable bloc, and vice versa, in a traumatizingly short amount of time if recent years can be a teacher
