John Stuart Mill · Politics
Mill’s one simple rule for the limits of liberty: society may interfere with your freedom only to prevent harm to others - never for your own good.
In On Liberty (1859), Mill set out to answer a question every society faces: how much may the community - through law, or through sheer social pressure - control the individual? His answer is one of the most influential sentences in political thought, what he called ‘one very simple principle.’ Power may be used against a person’s will for one reason only: to prevent them harming others. Their own good, physical or moral, is never a sufficient warrant.
The most radical edge of the principle is its rejection of paternalism - the idea that society may coerce you ‘for your own good.’ Mill insists you may be reasoned with, persuaded, entreated, but never compelled, when only your own welfare is at stake. The reason is partly that each person is the best judge of their own interests, and partly something deeper: that being free to run your own life, even to make your own mistakes, is itself essential to your dignity and development. A person’s own good is not a sufficient reason for compulsion, because the very point of life is to live it as one’s own.
The heart of Mill’s principle is the attempt to define and protect a self-regarding sphere - a region of life that is properly the individual’s own, into which neither law nor public opinion may rightfully intrude. Mill maps it carefully. It includes, first, the ‘inward domain of consciousness’: liberty of thought and feeling, of conscience, opinion, and sentiment on all subjects. Second, liberty of tastes and pursuits - of framing the plan of our own life to suit our own character, doing as we like, subject to such consequences as may follow, without impediment from others so long as what we do does not harm them. Third, the liberty, following from this, of combination - of individuals to unite for any purpose not involving harm to others. A society in which these liberties are not respected, Mill says, is not free, whatever its form of government; and the only freedom worthy of the name is that of pursuing our own good in our own way.
This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.
You learned that Mill divides actions into self-regarding and other-regarding. Explain where the harm principle permits interference and where it forbids it, in your own words.
Leads to John Rawls.
