As before, I found the question on metaethics (31) to be a tossup because I agree with several of the options given. I'd be interested in hearing from people who agree with some but not all of these answers:

• Non-cognitivism: Moral statements don't express propositions and can neither be true nor false. "Murder is wrong" means something like "Boo murder!".
• Error theory: Moral statements have a truth-value, but attempt to describe features of the world that don't exist. "Murder is wrong" and "Murder is right" are both false statements because moral rightness and wrongness aren't features that exist.
• Subjectivism: Some moral statements are true, but not universally, and the truth of a moral statement is determined by non-universal opinions or prescriptions, and there is no non-attitudinal determinant of rightness and wrongness. "Murder is wrong" means something like "My culture has judged murder to be wrong" or "I've judged murder to be wrong".

I'm a subjectivist: I understand that when someone says "murder is wrong", she's expressing a personal judgement - others can judge differently. But I also know that most people are moral realists, so they wrongly think they are describing features of the world that don't in fact exist; thus, I believe in error theory. And what does it mean to proclaim that something "is wrong", other than to boo it, i.e. to call for people not to do it and to shun those who do? Thus, I also agree with non-cognitivism.
