John Stuart Mill's book Utilitarianism is a classic exposition and defence of utilitarianism in ethics. The essay first appeared as a series of three articles published in Fraser's Magazine in 1861 (vol. 64, p. 391-406, 525-534, 659-673); the articles were collected and reprinted as a single book in 1863. Mill's aim in the book is to explain what utilitarianism is, to show why it is the best theory of ethics, and to defend it against a wide range of criticisms and misunderstandings. Though heavily criticized both in Mill's lifetime and in the years since, Utilitarianism did a great deal to popularize utilitarian ethics and has been considered "the most influential philosophical articulation of a liberal humanistic morality that was produced in the nineteenth century.
Mill took many elements of his version of utilitarianism from Jeremy Bentham, the great nineteenth-century legal reformer, who along with William Paley were the two most influential English utilitarians prior to Mill. Like Bentham, Mill believed that happiness (or pleasure, which both Bentham and Mill equated with happiness) was the only thing humans do and should desire for its own sake. Since happiness is the only intrinsic good, and since more happiness is preferable to less, the goal of the ethical life is to maximize happiness. This is what Bentham and Mill call "the principle of utility" or "the greatest-happiness principle." Both Bentham and Mill thus endorse "classical" or "hedonistic" forms of utilitarianism. More recent utilitarians often deny that happiness is the sole intrinsic good, arguing that a variety of values and consequences should be considered in ethical decision making.[4]
Although Mill agreed with Bentham about many of the foundational principles of ethics, he also had some major disagreements. In particular, Mill tried to develop a more refined form of utilitarianism that would harmonize better with ordinary morality and highlight the importance in the ethical life of intellectual pleasures, self-development, high ideals of character, and conventional moral rules.
John Stuart Mill (20 May 1806 - 7 May 1873) was an English philosopher, political economist, Member of Parliament (MP) and civil servant. One of the most influential thinkers in the history of classical liberalism, he contributed widely to social theory, political theory, and political economy. Dubbed "the most influential English-speaking philosopher of the nineteenth century" by the Stanford Encyclopedia of Philosophy, he conceived of liberty as justifying the freedom of the individual in opposition to unlimited state and social control.Mill was a proponent of utilitarianism, an ethical theory developed by his predecessor Jeremy Bentham. He contributed to the investigation of scientific methodology, though his knowledge of the topic was based on the writings of others, notably William Whewell, John Herschel, and Auguste Comte, and research carried out for Mill by Alexander Bain. He engaged in written debate with Whewell.A member of the Liberal Party and author of the early feminist work The Subjection of Women, Mill was also the second Member of Parliament to call for women's suffrage after Henry Hunt in 1832
