The principle of legal paternalism justifies state coercion to protect individuals from self-inflicted harm, or in its extreme version, to guide them, whether they like it or not, toward their own good. Parents can be expected to justify their interference in the lives of their children on the ground that “daddy knows best.” legal paternalism seems to imply that since the state often can know the interests of individual citizens better than the citizens know them themselves, it stands as a (...) permanent guardian of those interests in loco parentis. Put in this blunt way, paternalism seems a preposterous doctrine. If adults are treated as children they will come in time to be like children. Deprived of the right to choose for themselves, they will soon lose the power of rational judgment and decision. Even children, after a certain point, had better not be “treated as children,” else they will never acquire the outlook and capability of responsible adults. (shrink)
