 What of the substance of democratic government? Though Mill is an advocate of limited government in ways that one might expect given his defense of basic liberties in On Liberty, he is no libertarian. He emphatically rejects the idea that legitimate government is limited to the functions of affording protection against force and fraud (PPE V.i.2). Instead, he thinks that there are a variety of ways in which government can and should intervene in the lives of citizens—sometimes as coercer and other times as enabler or facilitator—in order to promote the common good. Mill’s claims about happiness imply that the good of each consists in the exercise of her higher capacities. This requires an active life in which one’s activities are regulated by one’s deliberations and choices. As we have seen in Mill’s critical discussions of paternalism, this places limits on how others can promote one’s own good. I can’t promote your good, understood in this way, in ways that bypass your agency anymore than I can win a race for you. But just as I can do things to help you win the race yourself (training with you, sharing nutritional tips, and helping you plan strategy), so too I can do things that help you lead an autonomous life. I can provide various sorts of necessary conditions for your leading such a life. If an individual’s good consists in this sort of self-realization, then a government which aims at the common good should concern itself in significant part with the fair provision of opportunities for welfare.
