On Liberty is a philosophical essay by the English philosopher John Stuart Mill. Published in 1859, it applies Mill's ethical system of utilitarianism to society and state. Mill suggests standards for the relationship between authority and liberty. He emphasizes the importance of individuality, which he considers prerequisite to the higher pleasures—the summum bonum of utilitarianism. Furthermore, Mill asserts that democratic ideals may result in the tyranny of the majority.

In the tract on Liberty, Mill is advocating the rights of the individual as against Society at the very opening of an era that was rapidly coming to the conclusion that the individual had no absolute rights against Society. The eighteenth century view is that individuals existed first, each with their own special claims and responsibilities: that they deliberately formed a Social State, either by a contract or otherwise, and that then finally they limited their own action out of regard for the interests of the social organism thus arbitrarily produced.

Mill's book Utilitarianism first appeared as a series of three articles published in Fraser's Magazine in 1861 and was reprinted as a single book in 1863. John Stuart Mill was brought up as a Benthamite with the explicit intention that he would carry on the cause of utilitarianism. Utilitarianism is a family of consequentialist ethical theories that promotes actions that maximize happiness and well-being for the majority of a population. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is to in some sense maximize utility.
