# On Liberty *John Stuart Mill, with Harriet Taylor Mill (see section 6). First published in London in 1859. The 1859 text is in the public domain.* > I read the full English text of *On Liberty* for this note (the Project Gutenberg edition, #34901). The chapter outline and quotations come from that text; the reception section comes from Wikipedia, and the biography from the Stanford Encyclopedia of Philosophy and Wikipedia. I did not read any scholarly literature on the book. ## 1. Book facts | | | |---|---| | Title | *On Liberty* | | Author | John Stuart Mill.

Anything published before 1931 is in the public domain in the United States ([Cornell chart](https://guides.library.cornell.edu/ld.php?content_id=83345575)), and life plus 70 years has also run out. New editions with fresh editorial material (like Hackett's 2026 volume) remain in copyright; the 1859 text does not. ## 3. Author biography **John Stuart Mill** (20 May 1806 – 7 May 1873), English philosopher and political economist ([SEP](https://plato.stanford.edu/entries/mill/); [Wikipedia](https://en.wikipedia.org/wiki/John_Stuart_Mill)): - Born in Pentonville, London, eldest son of the Scottish philosopher and historian James Mill, who educated him; Wikipedia says Jeremy Bentham advised and helped. Wikipedia reports he began Greek at three and Latin at eight, and that his father's explicit aim was to create a mind that would carry on the utilitarian cause. - At about twenty he suffered a "mental crisis" (SEP). Wikipedia says he followed his father into the East India Company instead of going to Oxford or Cambridge, and wrote its defence when the Crown moved to take over the Company's territories. - Met Harriet Taylor at a dinner in 1830 (SEP; the Courtney introduction in the Gutenberg text says 1831). Her husband John Taylor died in 1849 and she and Mill married in 1851 (SEP). Mill credited her with a large share in his work, and she died in 1858, in France, while they were travelling; she is buried at Avignon (SEP). - Sat in Parliament for three years and was defeated at the next general election; the Courtney introduction says he then retired to Avignon. The BBC page lists a book on his time at Westminster dated 1865-1868. Wikipedia lists him as co-author of *The Subjection of Women* (written 1861, published 1869), an early feminist work. - Died 7 May 1873 at Avignon of erysipelas and was buried beside Harriet (Wikipedia). Sources: [SEP, John Stuart Mill](https://plato.stanford.edu/entries/mill/); [Wikipedia, John Stuart Mill](https://en.wikipedia.org/wiki/John_Stuart_Mill); W. L. Courtney's introduction in the [Gutenberg text](https://www.gutenberg.org/ebooks/34901). Harriet Taylor's own dates were not checked. ## 4. Author interviews and talks Mill gave no interviews; he died in 1873, so there is nothing to link. Talks and discussions *about* the book that I verified: - [BBC Radio 4, *In Our Time*: "On Liberty"](https://www.bbc.co.uk/programmes/m002pqnc). Misha Glenny, in his first edition as presenter, discusses the book with Helen McCabe, Mark Philp and Piers Norris Turner, including Harriet Taylor Mill's co-authorship. The page lists 15 January 2026 as the first broadcast (page read; I did not listen to the audio). - Hackett's page also links a BBC discussion with two of the new edition's editors ([Hackett page](https://hackettpublishing.com/on-liberty-with-related-writings)); this appears to be the same *In Our Time* episode, though I did not confirm that. ## 5. Summary **Thesis.** The essay sets out "one very simple principle": that "the sole end for which mankind are warranted, individually or collectively, in interfering with the liberty of action of any of their number, is self-protection", and that "the only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant." It applies equally to law and to the pressure of public opinion. Mill adds: "Over himself, over his own body and mind, the individual is sovereign" (Chapter I). **Chapter-by-chapter outline** (read from the Gutenberg text; Wikipedia's chapter summaries used as a cross-check): 1. **Introductory.** States the principle above, says it applies only to adults in "the maturity of their faculties", and names "the tyranny of the majority" as a danger that includes social pressure as well as law. 2. **Of the Liberty of Thought and Discussion.** Argues that silencing an opinion is wrong even if only one person holds it: "If all mankind minus one, were of one opinion... mankind would be no more justified in silencing that one person". Gives four grounds: the opinion may be true; it may contain part of the truth; even a true opinion unchallenged is held as "a dead dogma, not a living truth"; and the doctrine itself loses meaning. 3. **Of Individuality, as one of the Elements of Well-being.** Defends "experiments of living" and says "Human nature is not a machine to be built after a model... but a tree". Warns of "collective mediocrity" and that "Genius can only breathe freely in an atmosphere of freedom". Compares enforced conformity to "a Chinese lady's foot". 4. **Of the Limits to the Authority of Society over the Individual.** Asks "What, then, is the rightful limit to the sovereignty of the individual over himself? Where does the authority of society begin?" and separates conduct that concerns only the person from conduct that affects others. Wikipedia's summary says the rest of the chapter answers objections (for example, about the young and about religiously motivated rules); I did not re-check each of those against the text. 5. **Applications.** Opens by restating the principle as two maxims: the individual is not accountable to society for actions that concern the interests of no one but himself, and for actions "prejudicial to the interests of others" he is accountable and "may be subjected either to social or to legal punishment" if society thinks it necessary for its protection. Then applies them to trade, poisons, taxation of stimulants, drunkenness, education and the limits of state action (details under "Key ideas"). Ends with the argument that "The worth of a State, in the long run, is the worth of the individuals composing it". **Key ideas.** - **The harm principle.** Self-regarding conduct is free; conduct that harms others is open to correction. - **Fallibility.** Free discussion is the way truth survives and is understood, rather than inherited. - **Individuality** is part of well-being, not a luxury. - **Intoxicants (the passage that bears on the video).** - Mill treats the Maine Law and other bans on the sale of a commodity as "questions of liberty", "objectionable, not as infringements on the liberty of the producer or seller, but on that of the buyer". - He says drunkenness "in ordinary cases, is not a fit subject for legislative interference". He allows a special penalty for a person already convicted of violence while drunk. - To tax stimulants "for the sole purpose of making them more difficult to be obtained" differs "only in degree from their entire prohibition". But taxation of stimulants "up to the point which produces the largest amount of revenue... is not only admissible, but to be approved of." - **Where Mill allows the state to act.** In Chapter V he says a drug may be labelled as dangerous "without violation of liberty", and that someone about to cross a bridge known to be unsafe, with no time to warn him, may be seized and turned back "without any real infringement of his liberty". He also says the dealers' interest in promoting intemperance "is a real evil, and justifies the State in imposing restrictions and guarantees", while rejecting the Maine Law because dealers are needed for legitimate use. - **Tobacco.** The word "tobacco" does not occur in the essay (searched the full text). "Smoking" appears once, in a list of tastes people may have without blame. **Reception** (from [Wikipedia](https://en.wikipedia.org/wiki/On_Liberty)): popular after publication (Thomas Hardy recalled undergraduates in the 1860s knowing it almost by heart). Nineteenth-century critics included Carlyle, James Fitzjames Stephen and Matthew Arnold. A later line of criticism holds that the essay sits awkwardly with Mill's utilitarianism; Nigel Warburton is cited for the comet example and David Brink for attempts at reconciling the two. A copy of the book is the symbol of office of the president of the UK Liberal Democrats. ## 6. Fact-check Overall verdict: **supported**. The video's quotation of the principle is accurate, and its remarks on taxing tobacco and drink are consistent with Mill's text. Two phrases attributed to Mill's side of the argument are the speaker's, not his, and the video's "Mill cuts both ways" is an application, not a Mill statement. The title-page authorship is now disputed (see the co-authorship row). | Claim | Verdict | Evidence | |---|---|---| | Power may rightfully be used over a member of a civilised community only "to prevent harm to others" (video, 0:46) | Supported | Chapter I of the [Gutenberg text](https://www.gutenberg.org/ebooks/34901): "...against his will, is to prevent harm to others" | | The body is "the last republic he governs" | Not Mill's wording | The video attributes this to the speaker's gloss on Mill. Mill's phrase is "Over himself, over his own body and mind, the individual is sovereign" (Chapter I). The idea is the same; the wording is not his | | Mill cuts both ways: smoking in a crowded room or on a plane is trespass | Consistent with Mill, not in the text | The essay does not discuss smoking in rooms or planes. It does say conduct that harms others may be controlled (second maxim, opening of Chapter V) | | The state taxes tobacco and drink | Consistent with Mill | Mill approves taxing stimulants for revenue and disapproves taxing them solely to deter use (Chapter V, quoted above). The video's description of taxes as an alternative to abolition is not in Mill | | Mill opposed prohibition of alcohol | Supported | Chapter V names the Maine Law as a question of the buyer's liberty. He also says dealers' interest in promoting excess justifies "restrictions and guarantees" on them; I read this as a qualification, not a reversal | | *On Liberty* was published in 1859 | Supported | [Wikipedia](https://en.wikipedia.org/wiki/On_Liberty); [BBC](https://www.bbc.co.uk/programmes/m002pqnc); the Courtney introduction in the Gutenberg text | | Mill alone wrote *On Liberty* | Disputed | Mill's dedication calls Harriet "the inspirer, and in part the author, of all that is best in my writings" and says the book "belongs as much to her as to me". Wikipedia quotes his *Autobiography*: "more directly and literally our joint production than anything else which bears my name". Wikipedia cites a 2022 stylometric study (*Utilitas* 34(2): 120-138) supporting co-authorship, and Hackett's 2026 edition credits her as co-author ([Hackett](https://hackettpublishing.com/on-liberty-with-related-writings)). I did not open the 2022 study | | The book is consistent with utilitarianism | Contested | Mill says in Chapter I, "I regard utility as the ultimate appeal on all ethical questions"; Warburton (via Wikipedia) argues the essay can seem divorced from that standard; Brink argues for reconciliation. Open scholarly debate, not settled here | ## 7.
