All right, I’ll play.
I’ll agree with 1, 2, and 3 but stop right there at 4.
STEP FOUR: ABSOLUTE MORAL LAWS
I don’t agree that if I don’t believe in absolute moral laws, that means I think the Nazis have the right to torture and murder me. Nobody has any sort of rights in this sense. The universe didn’t give either me or the Nazis any sort of rights. So I don’t have a right to not be tortured and the Nazis don’t have the right to torture. They might have the power to torture, and I might not be able to stop them, or maybe I do. Either way rights have nothing to do with it, except what we human beings decide for ourselves.
Do I want the Nazis to torture me? No I do not. Not because it violates God’s law, but because torture hurts and I don’t like it. I want there to be a rule against torture, not because God doesn’t like it, but because I’d rather live in a society where we have a rule against torture. Now, just because I have a preference for no torture, why does that give me the right to decide we shouldn’t have torture?
I don’t have that right. What I do have is the power to communicate with my fellow creatures, and tell them that if only we all agree to work together and not torture each other we’ll all be better off. And if someone breaks the “no torture” rule I don’t appeal to God to punish them, I realize I have to do something about it myself. Since I’m a fallible mortal human being, this mostly means trying to convince people to act together to stop the bad guys. And because most other human beings are fallible and mortal and realize that if the bad guys get together and do what they want we’re all going to be screwed, they agree with me.
And so the Nazis are wrong, not because God says they’re wrong, but because I say they’re wrong. And I don’t have a “right” to say they’re wrong, I just have my fallible mortal personal preference. It turns out that in 2016 America lots and lots of people share that preference, and so we (usually) work together to prevent the Nazis from doing too much damage. If I lived in Assyria in 1000 BC then nobody would listen to me, and organized maniacs with bronze swords and chariots could do whatever they liked and there wouldn’t be anything I could do about it.
And so we see that we all work together we get 2016 America where most people peacefully go to warm beds with full stomachs, vs 1000 BC Assyria where life is nasty, brutish and short. No universal absolute moral law there, just my personal preference, and also the personal preference of 300 million of my closest friends. And if the Nazis prove stronger than us and overthrow our government and enslave and murder us, that doesn’t make the Nazis right, it just makes them stronger. And eventually the human species will go extinct and it will all be over anyway.
And even if there were a universal set of absolute moral rules, how do we figure out what those are? We inspect our consciences, and find that rape and murder offend our consciences, and therefore these are absolute moral laws handed to us by God?
Except how is this different than saying that we have a personal preference for avoiding being raped and murdered? God isn’t going to enforce the no murder law, it’s up to us humans. And if Charles Manson over there likes rape and murder is fine with him, how is telling him that he’s breaking God’s Law supposed to help? Either we stand aside and let him rape and murder, or we work together to stop him. Either way the only solution is human agency enforcing human-created rules that only work because a lot of people agree with those rules and they make sense to us.
And they only make sense to us because we’re a particular sort of social creature with a particular social organization and a particular evolutionary history. If we were different, our ideas about what is fair or unfair would be different. And even among different human societies we have vastly different ideas about right and wrong. Is it wrong to marry your cousin? It it wrong to kill people who violate the rules? Is it wrong for a man to lay with another man? Is it wrong to evade paying taxes? Is it wrong to kill someone who insults religious or governmental authority?
And on and on. And the only way to resolve all this is to look at the consequences of various particular choices, and deciding if those choices maks sense according to our fallible mortal personal preferences.
