 The claim that it would be rational to sacrifice any amount of a lower pleasure for a minuscule amount of a higher pleasure, though, seems too implausible to attribute to Mill—and in the passage cited, he only registers a sufficient condition for considering one pleasure of a higher quality to another, and not a necessary condition (Saunders 2011; Miller 2010: 58). In fact, Mill gives very little indication as to how to weigh quality against quantity of pleasure—he simply does not speak to the specifics of how varying quantities of pleasures at varying qualities are to be reconciled against one another.
