 Green develops his ideas about the personal good in Book III of the Prolegomena. There he criticizes hedonism and develops his own perfectionist claims. Hedonism can be a psychological doctrine or an evaluative doctrine about the personal good. Green’s discussion of hedonism focuses on the utilitarian tradition, especially the views of Mill and Sidgwick. Green thinks that Mill combines psychological and evaluative hedonism, though that is disputable (Brink 2013: chs. 2–3). Sidgwick clearly distinguishes the two forms of hedonism, rejecting psychological hedonism and defending evaluative hedonism. Since Sidgwick explicitly accepts evaluative hedonism while rejecting psychological hedonism, Green must argue differently against Sidgwick.
