FJ, are you denying that the sum total of your response to each argument was roughly one line each, just stating that you disagreed with some premise, but not stating why? Because if you are, I’ll be happy to quote you. And if you’re not, then recognize that that’s no reason to agree with anything you’ve said.
The main area of discussion you wanted to focus on was about the distinction between prudence and morality. That’s fine, but those arguments work whether you think there’s an essential distinction or not.
You focused also on the case of masochism, and how that must be reason to think causing pain has nothing to do with morality, or something. That’s been addressed, and anyone can look at it. No masochist values pain, they value the psychological pleasure that only comes from physical pain. And if some masochist values pain----then that’s a subjective moral fact, and you can no longer claim not to know what a moral fact is.
You still seem to think moral facts must be something like facts with an offical stamp on them, a metaphysical name-tag, or a little halo around their molecules. And perhaps you think it’d be clever to pipe up and say there are no such things. Moral facts are ordinary everyday facts that furnish you with a reason to act one way rather than another. Do you want to throw your child off a bridge? You don’t, do you. That desire that you have is a fact----and it gives you a reason not to throw your child off a bridge, hence it is a moral fact. That’s very likely a subjective fact. But that’s fine—because you’re not even sure what a moral fact is. A moral fact is just a fact that gives you a reason to act one way or another. That an action causes pain—that’s a fact, it’s also a moral fact because it usually furnishes you with a reason not to commit that action. That’s moral fact. It’s really fucking simple. No, it doesn’t have a fucking metaphysical postcard on it… but what the fuck do you think we’re talking about?
