Hi dclements,
But is it really just that simple as you say?
It's definitely not simple, and I really had no intention to imply that choosing “the good” is simple. I think we all know that it isn't.
For example what happens if the God you choose to follow has morality that is a bit what you could call 'arbitrary' (ie. there is no rhyme or reason to what he/she/it chooses to do), then you become mere plaything to this all-powerful or at least more powerful being if you just say whatever they choose goes. In horror genre such as Lovecraft's Cthulhu mythos, humanity is tormented by evil god/God like beings who sometimes even worship them even though their are often more demon and god-like.
There's always the possibility that if some sentient being is a SUPREME DEFINER, there could be the chance that we might find arbitrary rules in the mix somewhere. However, the question comes down to whether or not we actually do perceive that arbitrary commands are being made. If we don't perceive arbitrariness, then we won't know that it is the case, even if it is. As for the Cthulhu mythos, I wouldn't put it past those kinds of beings to be arbitrary (or worse).
In a world troubled by such evil beings, is 'good' defined by the will of such god-like/demon beings (if they don't know anything about Christianity and Abrahamic religions) or do they still have rights and responsibility to follow what they believe is 'good' regardless of the whims of such beings?
I'm not so much concerned with applying existential thought to hypothetical worlds; our real world is existentially difficult enough to deal with as it is.
You mention trouble by “evil beings.” The next question would be then: Is our world troubled by such evil beings? How would you know they are evil, by the way? And if these beings are evil, are they identified as such from their own point of view, or from the view of Christianity, or some other form of Supreme Definer? Because, if these beings are evil according to Christian standards, then the implication would be that those evil beings would be more like Satan in their morality (or rather in their immoral characteristics), and they would be considered evil BECAUSE they shirk the responsibilities and rights as define by the Biblical ethos.
I'm kind of trending on thin ice here since this is a Christian forum and I don't want to say anything negative about Christianity or faith in God itself, but I think it is safe to say that one CAN NOT just do what they think God wants them to if such actions involve hurting others and not expect other people to let them get away with it. Such an example of such behavior include ISIS who believe hurting and murdering people in the name of Allah is the right thing to do.
I can agree with you here to some extent. Sure, some people will think it isn't preferential to have to clash ideologically with other minds over who and what sense of “the good” is to win out. But, it is obvious that some people actually DO things which they think their God is telling them to do, and they will do these things whether we like it or not.
Also there is the issue of how in the Old Testament, God didn't seem to be that much of a nice guy and seemed to dispense punishment and justice...well more arbitrary then we imagine a wise and good God would. While this changed in the New Testament, the fact that God behaved as he did in the Old and then changed in the New can create problems in itself as well.
Actually, if you read the New Testament in full, there's plenty there to show that Jesus acts in ways similar in ways to those portrayed in the Old Testament—there were rules for Blessings and Curses. The one significant difference between the Testaments is that Jesus extends Mercy, Grace, and Love before ultimate Judgment, … but judgment in the New Testament still comes at some point in the future, nevertheless.
I guess what I'm trying to say is that there seems to be holes in your argument,
I'm sure there always could be a hole here or there ...
... not the least it potentially being an appeal to authority or antiquity fallacy
If you'll review what I said in the previous posts, the existential state each of us finds ourselves in will be privy to various influences, some of which will be perceptions felt which pertain to religious notions that not all of us share. Moreover, an appeal to authority is only a fallacy if the authority being appealed to is one that has little to no credibility or power. Some people may feel they existentially perceive that a only dusty religious book exudes credibility or power; other people may not.
... and that it isn't a given that doing as you say is always the right thing to do
No, it isn't always a given, because discerning the good is difficult for all of us existentially.
... in the context of a philosophically argument and not necessarily anything against Christianity or other Abrahamic religions of course.
That's fine if you think you see holes in my points. You're free to think so. I don't think I'll lose the shirt off my back if you disagree with me.
Please realize that in sharing my existential point of view about how I think we each generally determine “the good,” I'm not presenting a prescriptive method for anyone to follow; rather, I'm being descriptive, and I want to merely express my point of view. And since discerning “the good” and/or morality is difficult for all of us, I am under no illusions that what I've said here will be something you'll want to adopt without at least some serious scrutiny.
Peace,
