Amongst the variations in certainty listed in my last post, there is the position in which someone takes specified beliefs to be no just indubitable, but infallible. There is a way of thinking in which the believer takes the position that certain of their beliefs are true even if everything else were to count against those beliefs. These beliefs are to be held despite of the evidence, and despite their consequences. — Banno
You envision a scenario where one believes X is wrong, but some authority tells him otherwise (perhaps a person or writing) and so he over-rules his belief and favors the authority, not from duress or fear of reprisal from his community, but from sincere reconsideration because he is faithful to that authority.
And you worry about this scenario because that person ignored all that counted against the authority and sided with the authority and then did something terrible.
This of course ignores the counter situation, where someone has plans to do something terrible, yet the authority steers him to the right path, causing the man to over-rule all that he considered as counting in favor of acting badly. This counter scenario might just be the more common occurrence, but be that as it may.
The question that is begged here is which authority do we honor? Do we honor our own conclusions and assume them correct and that be the authority, or do we rely upon some external authority and consider it?
Let's put this in the concrete with an example. Let us say that a co-worker of mine gets behind at work and he works on the sabbath. As we know, per Exodus 31:15, "Six days shall work be done, but the seventh day is a Sabbath of solemn rest, holy to the Lord. Whoever does any work on the Sabbath day shall be put to death." My personal thought is that this man should live, but I know the Bible is right, so I slaughter this man. So there's a good example of the conflict you envision: Authority A which guides modern society says it's wrong to kill my co-worker, but Authority B from our time honored past says I've got to kill him.
So much counts against his killing, but a good man (me) was turned evil due to this faith in authority problem you're talking about.
But here's the problem with your position. The problem with the killing had nothing to do with reliance upon authority. It had to do with relying upon the
wrong authority. I obviously agree A was the right authority and the man's life should have been spared, but Authority A is an authority just as much as B.
It's just that A is a good authority and B is not.
What does Authority A consist of in our example? I suspect it might be reason, experience, logic, the sound of our parents ringing in our heads, social norms, and maybe all sorts of other things.
What does Authority B consist of in our example? The literal translation of the Bible.
And that again brings us full circle to what we
always talk about, which I submit is your unrealistic, strawman position of what Authority B really is. When we look at the world, and we see all the power that is given to the Bible, and we read Exodus 31:15, yet we see that exactly zero people are being killed for disobeying the law of keeping the Sabbath. What this means is that Authority B likely contains much of Authority A as well, which explains why more often than not we get the same results.
