 Another worry is there is very little agreement in intuitions or claims to self-evidence. This suggests for some there is no fact of the matter as to what has value or what one is responsible for. Ross concedes there is a lot of disagreement. His response begins by noting a lot of moral diversity rests not on ‘disagreement about fundamental moral principles, but partly on differences in the circumstances of different societies, and partly on different views which people hold, not on moral questions but on questions of fact’ (FE 18). He thinks most of the differences concern media axiomata, i.e., attempts to apply general principles to particular circumstances, which rest on different circumstances or different factual beliefs (FE 18–19). About middle principles, he says intuitionists must have an open mind (FE 190).
