“Authority” is not one thing. Aristotle might remind us that it is said in many ways. Two of the most important have nearly opposite senses. One asserts an arbitrary power over others, or an entitlement to coerce others: “Do what you are told”. Why? “Because I said so”. The other is a kind of earned respect that is virtually identical with justification.
An important case is what is called argument from authority. There are practical situations in which very rapid response is required, and there is literally no time for debate. We don’t hesitate to simply grab a child who is in danger from an oncoming car, and we don’t consider this a violation of Kantian respect for others. We also tend to trust the judgment of those we judge to have good judgment. But in any situation in which what is good or what is true is disputed, argument from authority is basically cheating.
“Because I said so” or “because someone in authority said so” is logically circular, and a circular argument does not establish anything. A particularly insidious version of this is appeals to the will of God, as if all by itself this were a criterion of what is right.
What these conceal is the speaker’s unboundedly prideful implicit claim to personally know the will of God beyond any doubt, regardless of anyone else’s contrary view of what the will of God is.
Plato in his dialogue Euthyphro portrays Socrates as asking whether we should say that a thing is holy because the gods love it, or on the contrary that the gods love a thing because it is holy. ”Because the gods love it” or “because it is God’s will” is logically equivalent to “because I said so”, because the speaker simply assumes it is beyond doubt that the speaker’s view is God’s view.
Building on Plato, Leibniz asks whether a thing is good and just because God wills it, or whether God wills it because it is good and just, and answers that it must be the latter, because to assert the former would make of God a tyrant rather than a being good and just. If on the other hand God is good and just, and therefore wills whatever is actually good and just in each situation, then we are responsible for understanding what is good and just in each case.
Claimed entitlements to coerce others should require substantial justification. We might be tempted to say that no one should ever coerce anyone else, but there are sociopaths and Nazis who do not respect others at all. The problem is that once an authority to coerce is instituted, it takes on a life of its own, and is prone to abuse. As the saying goes, power corrupts, and absolute power corrupts absolutely. But occasionally, coercion is the only way to avoid a greater evil. There are no easy answers here.
