Alex Rosenberg in the New York Times:
Moral disputes seem intractable — more intractable than other disputes. Take an example of a moral position that most of us would consider obvious: Honor killing is wrong. But honor killing has its supporters. Anyone who suggests that we can compromise with its supporters on the matter misunderstands the nature of this type of disagreement. It’s absolute. One party has to be right. Us. So why can’t we convince those who hold the opposite view?
With some exceptions, political disputes are not like this. When people disagree about politics, they often agree about ends, but disagree about means to attain them. Republicans and Democrats may differ on, say, health care policy, but share goals — a healthy American population. They differ on fiscal policy but agree on the goal of economic growth for the nation. Of course, this is often a matter of degree. Political disputes can have moral aspects, too. The two sides in the debate over abortion rights, for instance, clearly don’t agree on the ends. There is an ethical disagreement at the heart of this debate. It is safe to say that the more ethical a political dispute is, the more heated and intractable it is likely to become.
Honor killing is the execution of one’s own family member, often a woman, who is seen to have brought disgrace to the family. It is a practice most of us find absolutely wrong, no matter the goal — in this case, restoring dignity to the family. The fact that it is a practice long sanctioned in other cultures does not matter to us. Meanwhile, those who approve of or carry out honor killings reject our condemnation, and most likely see it as a moral lapse of ours.
What makes moral disagreements so intractable? Ethics shouldn’t be as hard as rocket science.
