   Another factor that might explain moral disagreement is disagreement about the strength of certain moral reasons. Many disputants might agree about the non-moral facts, and about what is morally relevant, but disagree about the weight that should be given to the different moral considerations. So, for example, two people might disagree about whether they ought to push a large man onto the rail tracks to derail a trolley that would otherwise kill five people, but this is quite consistent with them agreeing that the fact that this act would save five people counts in favour of pushing the man off the bridge, and that the fact that he would die if this were done counts against doing it. In such a case there is agreement about what is relevant, and how it is relevant, but disagreement about the weight of the competing moral considerations—one person regards the evil of killing one person as weightier than the good of saving five, while the other regards the evil of killing one as outweighed by the good of saving the five. There is still moral disagreement here, but it is simply a difference in judgement about the application of agreed moral principles.
