Liberalism and paternalism are often seen as incompatible on the grounds that liberalism recognizes autonomy as the highest value, while paternalism limits autonomy for the sake of more valuable goods such as health and safety. This article offers an argument for the compatibility of liberalism and paternalism. At the heart of the argument is the philosophical distinction between having autonomy and exercising autonomy. The second way of defending autonomy is indeed incompatible with paternalism, but the first justifies paternalism when its (...) purpose is to limit choices that reduce one’s autonomy. A modified version of John Rawls’s veil of ignorance is presented to justify the preference for having autonomy over exercising autonomy. The practical consequences of this form of liberal paternalism are then examined and analyzed using three examples: voluntary sale of oneself into slavery, addiction to opioid drugs, and compliance with road safety measures (seat belt, motorcycle helmet). The argument presented provides a justification for liberal paternalism that does not rely on any controversial or perfectionist conception of the good, and is therefore compatible with the classical interpretation of liberal neutrality. It concludes by considering the compatibility of the proposed argument with other versions of liberal paternalism, including perfectionist, respectful, Kantian, libertarian, and left-libertarian paternalism. The conclusion is that all versions except the left-libertarian one is compatible with the justification described, while Peter Vallentyne’s left-libertarian paternalism suffers from internal inconsistency.
