The OP asked whether we should obligate ourselves on purely declared superiority (i.e. no confirmative evidence).
Nowhere in our every-day lives does this happen.
This is odd. I see this all the time. Especially around issues of concern to Greenberg, spiritual issues.
You gave example of parents, teachers etc - but this obligated submission is based on plethora of evidence - which helps in the subconscious risk/reward assessment.
As a baby we are utterly helpless - and submit ourselves to those who give us warmth, succour, food etc. This is the start of the evidence.
The overall authority may, I repeat may, be corroborated by evidence, say with competent parents. But about their moral awareness, spiritual insight, intelligence about specific issues or even in general, certainly there are many cases where there is no evidence.
At no point does a parent merely say: "I am your parent - you are obligated to me" and the child accept it. It is based on all of the evidence up to that point.
And this happens nowhere else in reality. Everything is based on evidence.
Feel free to come up with an example where there is merely a declared superiority and no action / evidence supporting it.
Do mean we need to find an example where someone has absolutely zero potential to do/be what they claim? That seems misleading.
Hitler could certainly offer some evidence, but it was overwhelmed by swathes of evidence, generally ignored, that he was the wrong person to lead Germany, as it turned out.
Police? No... there is a mountain of evidence of police being able to take away liberties for going against societal laws.
Teachers? No... there is plenty of evidence that teachers know what they are teaching - plus the ability to punish.
Bosses at work? No... there is plenty of evidence thorughout our lives that promotion is earned through ability - plus the risk of losing salary if we do not obligate ourselves.
Ah, you are not saying their authority is bases on merit, skill, intelligence, etc, merely that they can hurt you so that it is smart to follow them. But that is not really Greenberg's concern.
You can do what you boss tells you AND AT THE SAME TIME know the guy is a moron about purchasing. Or you can believe that he really knows what he is doing as a Purchasing Manager because he claims to despire the evidence to the contrary.
In all the situation above you are talking about respecting functional authority. But Greenberg is concerned about another kind of authority based on knowledge or skill. And there is no reason in all of these situations to assume that these people have that. One can respect their authority to cause one harm, without assuming that they are smart about who they harm and why let alone, for example, their ability to teach math, as opposed to giving you a bad grade.
The worst teacher on earth will give some evidence they can teach - they show up for class. A teacher needs to be present. This is some evidence....blah, blah blah. This does not mean they have any authority as a pedogogue.
