But that aside, I think the “smorgasboard” argument is a confused way of thinking about moral reasoning. A great many crucially important questions in normative ethics are easy. Is it okay to murder Greg Mankiw to steal the money in his pocket? No, it isn’t. But a lot of foundational questions in ethical theory are hard. And a lot of meta-ethical questions are hard. Normal people don’t even understand what all of these questions are. And those of us who’ve thought a little bit about them, but decided not to go into the professional philosophy game may be aware that there are issues in these areas about which we’re uncertain. There’s a certain hyper-literal sense in which these questions all form a hierarchy. First I must decide where I stand on meta-ethics. Am I a reductive moral realist? A quasi-realist? A practical reasons theorist? An old-school “moral facts are facts too, damnit” moral realist? Are there theological issues in play? Then I need to decide if I’m a utilitarian (and if so, what kind of utilitarian!) or maybe some other kind of consequentialist or maybe I have a more Kantian view. So then depending on those answers, I can say “killing Greg Mankiw to steal the money in his pocket is wrong because…” and then lay the whole thing out.-- Matt Yglesias
I think what Mankiw is implying with the “smorgasboard” argument is that this is how people should actually engage in moral reasoning. So if I find myself uncertain about a broad question in ethical theory, this uncertainty must logically inflict my first-order moral judgments. Maybe killing Greg Mankiw really is okay? And if I’m not uncertain, if I say “the reason it’s wrong to kill Greg Mankiw and steal his money is that the murder would reduce net utility” then the murderer can counter with “well, if you believe in utilitarianism, you ought to believe in a height tax.” Then I say “well that sounds wrong!” And then, having debunked utilitarianism, Mankiw gets shot and everyone agrees that justice has been done.
