lukeprog gave a list of metaethics questions here:
What does moral language mean? Do moral facts exist? If so, what are they like, and are they reducible to natural facts? How can we know whether moral judgments are true or false? Is there a connection between making a moral judgment and being motivated to abide by it? Are moral judgments objective or subjective, relative or absolute? Does it make sense to talk about moral progress?
Most of these questions make no sense to me. I imagine that the moral intuitions in my brain come from a special black box within it, a "morality core" whose outputs I cannot easily change. (Explaining how my "morality core" ended up a certain way is a task for evo psych, not philosophy.) Or I can be more enlightened and adopt Nesov's idea that the "morality core" doesn't exist as a unified device, only as an umbrella name for all the diverse "reasons for action" that my brain can fire. Either perspective can be implemented as a computer program pretty easily, so I don't feel there's any philosophical mystery left over. All we have is factual questions about how people's "morality cores" vary in time and from person to person, how compelling their voices are, finding patterns in their outputs, etc. Can someone explain what problem metaethics is supposed to solve?
I must say I agree with this, and it's reassuring to see someone else say it out loud.
I find that a lot of people who successfully make the step to a non-theistic world view are unable to then shed the baggage of moral realism. They continue to damn their intellectual opponents as demonstrably, factually "immoral". They just change the source of that objective morality from God to secular philosophy. It's uncomfortable to realize that your side isn't the one, true, noble cause. Thus, new atheists latch on to some political cause or the "cause of Reason" and assert it as the true objective good.
And hey, I support many of the goals of the "cause of Reason". I'm in favor of raising the sanity waterline and improving the instrumental rationality of my friends and colleagues. But that's a subjective value. That's my preference. And that's okay.
Great points! Was the final sentence intentional irony? :)
Edit to clarify: "And that's okay" seems to slip back into objective morality (although of course it is hard to avoid such phrasing in English).
