It seems that eudaimonistic reconstructions of John Stuart Mill's conception of happiness have fallen prey to what they thought Mill should have done with regard to the role of pleasure in his notion of happiness. Insisting that utility and eudaimonia make conflicting claims, something which mirrors Mill's ‘conflicting loyalties’, they downgrade pleasure to just one of the ingredients of happiness. However, a closer look at Mill's intellectual development suggests otherwise. By focusing on Mill's radical background, this paper argues that pleasure (...) retains a central role in his conception of happiness – even from a eudaimonistic point of view. (shrink)
