 For others, however, it is clear enough that Sidgwick’s hedonistic utilitarianism does not require any Rossian apparatus for recognizing apparent conflicts of duties. De Lazari-Radek and Singer, in response to Crisp’s defense of Rossian prima facie intuitions, argue that “Ross starts by assuming that, as he puts it, ‘the main moral convictions of the plain man’ are ‘not opinions which it is for philosophy to prove or disprove, but knowledge from the start.’ As we have already indicated both in our book and in this response, we are skeptical about the validity of most of our moral intuitions” (de Lazari-Radek &amp; Singer 2016). Sidgwick would probably not have deemed the Rossian gambit to the point for purposes of dealing with the dualism of practical reason.
