  Furthermore, some intuitionists did not think that goodness is unanalysable. For instance, Sidgwick thought that good could be analysed as what ought to be desired, and Ewing maintained that it could be analysed as the fitting object of a pro-attitude. If the sense of mystery of the intuitionist notion of goodness stems from its unanalysability, then this sense of mystery will not apply to these intuitionists’ concept of goodness, even though it is still a non-naturalist conception. But critics might respond that these definitions really only move the mysterious notion elsewhere, e.g., to the unanalysable terms ‘ought’ and ‘fittingness’.
