Liberalism and communitarianism are the main viewpoints of legal- and social philosophy that inquire into the nature and limits of legal exercise of state power. According to harm principle based on classical liberalism, liberty-limiting interference can be justified to protect a person from not self-regarding harm, but other-regarding harm. But, legal moralism based on communitarianism justifies liberty-limiting interference in order to protect a common morality itself as well as a person from harms. But, both of them have its own limitations in theory and practice. Paternalism is the most reasonable and plausible alternative to harm principle and legal moralism. It justifies interference with another for his own good. But, legal moralists argue against paternalism, while liberals who abhor moral legalism also criticise it. In a sense, paternalism contradicts harm principle on the one hand, legal moralism on the other hand. It paradoxically means that paternalism can be compatible with harm principle as well as legal moralism. Can paternalism really coexist with harm principle or legal moralism? Yes. The dual ambilaterality of paternalism makes it possible. The revelation of dual ambilaterality will be of use to the normative discussion of paternalism.
