Is there any way to settle moral disagreements?

When people disagree about moral issues, is there any rational way to resolve those disputes? Some think there are moral principles that any rational person must accept. But in “Can Moral Disputes Be Resolves?” Alex Rosenberg says there aren’t any such principles. The problem, according to Rosenberg, is that moral judgments are not true or false statements based on applying moral principles to particular circumstances. They are instead expressions of our responses to conduct. “Many people will not find this a satisfactory outcome. They will hope to show that even if moral judgments are expressions of our emotions, nevertheless at least some among these attitudes are objective, right, correct, well justified. But if we can’t find objective grounds for our emotional response to honor killing, our condemnation of it might turn out to just be cultural prejudice.”

Moral facts

Are there moral facts? For example, is it a fact that “copying homework assignments is wrong”? Or is this merely an opinion or belief? In “Why Our Children Don’t Think There Are Moral Facts,” Justin McBrayer explains that there are moral facts and along the way raises some useful distinctions about facts, values, beliefs, opinions, and the truth … though it’s clear from readers’ comments not everyone agrees. (Also, it’s “ad nauseam,” not “ad nauseum.”)
