Mill goes on to say that just as each person’s own happiness is a good to that person, so too happiness, as such, is a good to the aggregate of persons. But we need not suppose that Mill is attributing a psychology, much less an egoist psychology, to humanity as a group. Instead, we can read Mill as claiming that just as the agent’s own happiness is the object of prudential concern, so too happiness as such is the proper object of disinterested or impartial concern.
