 Earlier, we suggested that the harm principle would be more robust and better fit with Mill’s views about justified restrictions of liberty if we understood it is a harm prevention principle, essentially, as HP2A, rather than HP1A. Now we have seen how the harm principle would be more robust and better fit Mill’s views about justified restrictions of liberty if we understood it to regulate restrictions on basic liberties, rather than liberty per se. This requires us to interpret the harm principle as HP2B. We might call this the basic liberties harm prevention principle. But if we interpret the harm principle this way, then Mill is even further from a libertarian view, at least if libertarianism is understood as the idea that the only legitimate limit on individual liberty is to prevent that individual from acting in ways that harm others.
