On Liberty is a philosophical work by the English philosopher John Stuart Mill, originally intended as a short essay. The work, published in 1859, applies Mill's ethical system of utilitarianism to society and the state.Mill attempts to establish standards for the relationship between authority and liberty. He emphasizes the importance of individuality, which he conceived as a prerequisite to the higher pleasures-the summum bonum of utilitarianism. Furthermore, Mill criticizes the errors of past attempts to defend individuality where, for example, democratic ideals resulted in the "tyranny of the majority". Among the standards established in this work are Mill's three basic liberties of individuals, his three legitimate objections to government intervention, and his two maxims regarding the relationship of the individual to society. On Liberty was a greatly influential and well received work, although it did not go without criticism. Some attacked it for its apparent discontinuity with Utilitarianism, while others criticized its vagueness. The ideas presented in On Liberty have remained the basis of much liberal political thought. It has remained in print continuously since its initial publication. To this day, a copy of On Liberty is passed to the president of the British Liberal Democrats as a symbol of office. A copy of the same book is also presented to and then held by the president of the Liberal Party as a symbol of office. Mill's marriage to his wife Harriet Taylor Mill greatly influenced the concepts in On Liberty, which was largely finished prior to her death, and published shortly after she died.............. John Stuart Mill (20 May 1806 - 8 May 1873) was a British philosopher, political economist and civil servant. One of the most influential thinkers in the history of liberalism, he contributed widely to social theory, political theory and political economy. Dubbed "the most influential English-speaking philosopher of the nineteenth century", Mill's conception of liberty justified 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. Mill engaged in written debate with Whewell.[8] A member of the Liberal Party, he was also the first Member of Parliament to call for women's suffrage. Works: A System of Logic Main article: A System of Logic Mill joined the debate over scientific method which followed on from John Herschel's 1830 publication of A Preliminary Discourse on the study of Natural Philosophy, which incorporated inductive reasoning from the known to the unknown, discovering general laws in specific facts and verifying these laws empirically. William Whewell expanded on this in his 1837 History of the Inductive Sciences, from the Earliest to the Present Time followed in 1840 by The Philosophy of the Inductive Sciences, Founded Upon their History, presenting induction as the mind superimposing concepts on facts. Laws were self-evident truths, which could be known without need for empirical verification.....
