 Sometimes Mill suggests that the harm principle is equivalent to letting society restrict other-regarding conduct (I 11; IV 2). On this view, conduct can be divided into self-regarding and other-regarding conduct. Regulation of the former is paternalistic, and regulation of the latter is an application of the harm principle. So on this view it is never permissible to regulate purely self-regarding conduct and always permissible to regulate other-regarding conflict. But, as Mill himself concedes, very little conduct is purely self-regarding (IV 8). Some other-regarding conduct causes mere offense, not genuine harm (IV 3; IV 12). So Mill cannot equate harmful behavior and other-regarding behavior and cannot think that all other-regarding behavior may be regulated.
