Have you seen the “Obey” stickers, etc. from pop artist Shepard Fairey? According to Wikipedia, the purpose of the sticker is to motivate contemplation.
When I see such stickers, these questions come to mind:
Whom? What?
Why?
What moral right does one (sufficiently mature and rational) adult have to command obedience from another?
If such a right exists, in which cases is it valid, and what grounds this right?
Suppose the one who attempts to command is less rational than the one he tries to command. Is there a moral right for a less rational person to command a more rational one? Is the rationally superior person morally obligated to obey someone less rational?
The use of Andre the Giant’s face suggests that might makes right. But might doesn’t make right. Power isn’t morally normative merely because it’s powerful. Applied might, sans right, is mere coercion. So, why obey mere power?
If we are talking about moral duties, epistemic duties, etc., then since we have moral, epistemic, and logical oughts, we have reason to follow them. Interesting further question: what explains them?
