On Liberty

On Liberty (1859) was John Stuart Mill's influential justification of individual freedom. In this book, Mill set out to establish a ‘simple principle’—that the only legitimate reason for interfering with someone's action was to protect someone else; the good of the agent himself/herself was not sufficient warrant. Mill based his defence of liberty on utilitarian grounds, not on a natural right to freedom; arguing that on balance people were happier when left to choose their life-styles for themselves. He also believed that social well-being and scientific progress depended on the greatest possible freedom of expression and publication. His attack was directed not only at governmental paternalism but also at social conformity.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
