Abstract

J s mill's principle of liberty is often thought to say that the only good reason for interfering with a person's conduct is that it is harmful to others. An alternative interpretation is defended: that the only good reason for interfering is to prevent harm to others. Harm-Prevention is the aim, But the latter principle allows that conduct affected not be harmful; interference must be calculated to prevent harm to others, Perhaps indirectly. This accords with mill's official statement of his principle, Accommodates his own otherwise troublesome examples of cooperation and good samaritan requirements, And fits as well with the texts.
