 First, recall that Mill distinguishes between harm and mere offense. Not every unwelcome consequence for others counts as a harm. Offenses tend to be comparatively minor and ephemeral. To constitute a harm, an action must be injurious or set back important interests of particular people, interests in which they have rights (I 12; III 1; IV 3, 10, 12; V 5). Whereas Mill appears to reject the regulation of mere offense, the harm principle appears to be the one justification he recognizes for restricting liberty.
