 Ross is not hostile to the idea we might recognise a ‘new duty’ in light of new circumstances (FE 189). However, he does say ‘the general principles which it [i.e., intuitionism] regards as intuitively seen to be true are very few in number and very general in character’ (FE 190). He seems to think most disputes about his list would revolve around what should be added rather than what should be subtracted, since the responsibilities listed above are ‘authentic’ (RG 23), that is, responsibilities revealed upon sober reflection. But if new circumstances can lead to the recognition of new duties, why may they not lead to the recognition there are fewer basic duties than we might otherwise have supposed? This seems to be the nub of the issue between Ross and his ideal utilitarian foes.
