 This suggested way of blocking the Repugnant Conclusion obviously presupposes that the superiority view is justified in the first place (for a recent effort, see Parfit 2016). However, even if this is the case, critics have suggested that this view may still be consistent with some versions of the Repugnant Conclusion (e.g., Ryberg 1996b). Moreover, the superiority view has other implications that might be hard to accept. Assume that there are days of different qualities and that these can be arranged in a descending sequence of goodness or how much they would contribute to the well-being of a life. It seems plausible that there can be such a sequence where the difference in quality of any two adjacent days in the sequence is marginal. For example, consider two days of a life that only differ in respect to one pin-prick in the left thumb. Assume now, as Parfit suggests, that there are days of such quality that some number of these are better than any number of days eating potatoes and listening to muzak. One can then show (Arrhenius 2005; Klint Jensen 2008) that there must be two types of days, call them α-days and β-days, such that some number of α-days is better than any number of β-days although the difference in quality between these days is only marginal.
