 Another understanding of “harm” again takes its cue from Mill, this time from his many references to the “interests” of persons—for example: “insofar as these concern the interests of no person but himself” and “such actions as are prejudicial to the interests of others” (Mill On Liberty, ch. 5, para 2). The important distinction is not that which regards others versus that which regards oneself. It is that which is in the interests of others versus that which is in the interests of oneself. The seminal essay for this reading is from 1960 by John Rees (Rees 1960; cf. Saunders 2016), though Hart appears not to have been aware of it. Rees paved the way for Feinberg’s development of harm as “the setback of interests”. Hence, in addition to Feinberg’s addition of wrongfulness commented on above, Feinberg’s defines harm as “those states of set-back interest that are the consequence of wrongful acts or omissions by others” (Feinberg 1984: 215).
