There are certain kinds of moral belief that we view in a pluralistic manner, and others that we take to be absolute. For an example of the former, suppose that I'm a vegetarian who believes that eating meat is immoral. Most people would say that it's inappropriate for me to harangue meat eaters, since they are just as entitled to their beliefs about diet as I am to mine. By contrast, we don't reason this way about things like murder. I am not obligated to respect the beliefs of someone who thinks murder is permissible--on the contrary, I may be morally remiss if I don't try to stop or correct him. What explains the difference between these two kinds of moral belief?
