Right. Someone could be against slavery for THEM personally without being against slavery in general if they didn't realize that what was wrong for them was also wrong for others. That's all I'm getting at, there.

Or do you mean that they should have opposed slavery for everybody as a sort of game theory move to reduce their chance of ever becoming a slave?

"You do understand that debates about objective vs relative morality has been going on for millenia?"

What I'm getting at here is that most moral theories are so bad you don't even need to talk about evidence. You can show them to be wrong just because they're incoherent or self-contradictory.

It's a pretty low standard, but I'm asking if this theory is at least coherent and consistent enough that you have to look at evidence to know if it's wrong, instead of just pointing at its self-defeating nature to show it's wrong. If so, yay, it might be the best I've ever seen. :)

Huh? I'm against going to jail personally without being against the idea of jail in general. In any case, wasn't your original argument that ancient Greeks and Romans just didn't understand what does it mean to be a slave? That clearly does not hold.

Do you mean descriptive or prescriptive moral theories? If descriptive, humans are incoherent and self-contradictory.

Which moral theories do you have in mind? A few examples will help.

Mmm, that's not quite the right abstraction. You're probably against innocents going to jail in general, no?

Whereas some Roman might not care, as long as it's no one they care about.

All I'm getting at is that the Romans didn't think certain things were wrong, but if they were shown in a sufficiently deep way everything we know, they would be moved by it, whereas if we were shown everything they know, we would not find it persuasive of their position. Neither would they, after they had seen what we've seen.

I'm talking metaethics, what makes something moral, what it means for something to be moral. Failed ones include divine command theory, the "whatever contributes to human flourishing" idea, whatever makes people happy, whatever matches some platonic ideals out there somehow, whatever leads to selfish interest, etc.

That doesn't seem obvious to me at all.

Let's try it on gay marriage. Romans certainly knew and practiced homosexuality, same for marriage. What knowledge exactly do you want to convey to them to persuade them that gay marriage is a good thing?

So, prescriptive. I am not sure in which way do you consider the theories "failed" -- in the sense that they have not risen to the status of physics meaning being able to empirically prove all their claims? That doesn't look to be a viable criterion. In the sense of not having taken over the world? I don't know, the divine command theory is (or, at least, has been) pretty good at that. You probably wouldn't want a single theory to take over the world, anyway.
