• Philosopher and Political Economist John Stuart Mill, 1806
  

John Stuart Mill was born on Rodney Street in the Pentonville area of London, the eldest son of the Scottish philosopher, historian and economist James Mill, and Harriet Burrow. John Stuart was educated by his father, with the advice and assistance of Jeremy Bentham and Francis Place. He was given an extremely rigorous upbringing, and was deliberately shielded from association with children his own age other than his siblings. His father, a follower of Bentham and an adherent of associationism, had as his explicit aim to create a genius intellect that would carry on the cause of utilitarianism and its implementation after he and Bentham had died.

Mill was a notably precocious child. He describes his education in his autobiography. At the age of three he was taught Greek. By the age of eight he had read Aesop's Fables, Xenophon's Anabasis, and the whole of Herodotus, and was acquainted with Lucian, Diogenes Laërtius, Isocrates and six dialogues of Plato. He had also read a great deal of history in English and had been taught arithmetic.

At the age of eight he began learning Latin, Euclid and algebra, and was appointed schoolmaster to the younger children of the family. His main reading was still history, but he went through all the commonly taught Latin and Greek authors and by the age of ten could read Plato and Demosthenes with ease. His father also thought that it was important for Mill to study and compose poetry. One of Mill's earliest poetry compositions was a continuation of the Iliad. In his spare time, he also enjoyed reading about natural sciences and popular novels, such as Don Quixote and Robinson Crusoe.

His father's work, The History of British India was published in 1818; immediately thereafter, about the age of twelve, Mill began a thorough study of the scholastic logic, at the same time reading Aristotle's logical treatises in the original language. In the following year he was introduced to political economy and studied Adam Smith and David Ricardo with his father, ultimately completing their classical economic view of factors of production. Mill's comptes rendus of his daily economy lessons helped his father in writing Elements of Political Economy in 1821, a textbook to promote the ideas of Ricardian economics; however, the book lacked popular support. Ricardo, who was a close friend of his father, used to invite the young Mill to his house for a walk in order to talk about political economy.

At age fourteen, Mill stayed a year in France with the family of Sir Samuel Bentham, brother of Jeremy Bentham. The mountain scenery he saw led to a lifelong taste for mountain landscapes. The lively and friendly way of life of the French also left a deep impression on him. In Montpellier, he attended the winter courses on chemistry, zoology, logic of the Faculté des Sciences, as well as taking a course of the higher mathematics. While coming and going from France, he stayed in Paris for a few days in the house of the renowned economist Jean - Baptiste Say, a friend of Mill's father. There he met many leaders of the Liberal party, as well as other notable Parisians, including Henri Saint - Simon.

This intensive study however had injurious effects on Mill's mental health, and state of mind. At the age of twenty he suffered a nervous breakdown. In chapter V of his Autobiography, he claims that this was caused by the great physical and mental arduousness of his studies which had suppressed any feelings he might have developed normally in childhood. Nevertheless, this depression eventually began to dissipate, as he began to find solace in the Mémoires of Jean - François Marmontel and the poetry of William Wordsworth.

Mill had been engaged in a pen - friendship with Auguste Comte, the founder of positivism and sociology, since the two were both young men in the early 1820s. Comte's sociologie was more an early philosophy of science than we perhaps know it today, and the positive philosophy aided in Mill's broad rejection of Benthamism.

Mill refused to study at the University of Oxford or the University of Cambridge, because he refused to take Anglican orders. Instead he followed his father to work for the East India Company until 1858, and attended University College, London (UCL) to hear the lectures of John Austin, the first Professor of Jurisprudence. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1856.

In 1851, Mill married Harriet Taylor after 21 years of an intimate friendship. Taylor was married when they met, and their relationship was close but generally believed to be chaste during the years before her first husband died. Brilliant in her own right, Taylor was a significant influence on Mill's work and ideas during both friendship and marriage. His relationship with Harriet Taylor reinforced Mill's advocacy of women's rights. He cites her influence in his final revision of On Liberty, which was published shortly after her death. Taylor died in 1858 after developing severe lung congestion, after only seven years of marriage to Mill.

Between the years 1865 – 1868 Mill served as Lord Rector of the University of St. Andrews. During the same period, 1865-8, he was a Member of Parliament for City and Westminster, and was often associated with the Liberal Party. During his time as an MP, Mill advocated easing the burdens on Ireland. In 1866, Mill became the first person in the history of Parliament to call for women to be given the right to vote, vigorously defending this position in subsequent debate. Mill became a strong advocate of such social reforms as labor unions and farm cooperatives. In Considerations on Representative Government, Mill called for various reforms of Parliament and voting, especially proportional representation, the Single Transferable Vote, and the extension of suffrage.

He was godfather to the philosopher Bertrand Russell.

Mill died in 1873 of erysipelas in Avignon, France, where he was buried alongside his wife.

Mill's On Liberty addresses the nature and limits of the power that can be legitimately exercised by society over the individual. One argument that Mill develops further than any previous philosopher is the harm principle. The harm principle holds that each individual has the right to act as he wants, so long as these actions do not harm others. If the action is self - regarding, that is, if it only directly affects the person undertaking the action, then society has no right to intervene, even if it feels the actor is harming himself. He does argue, however, that individuals are prevented from doing lasting, serious harm to themselves or their property by the harm principle. Because no-one exists in isolation, harm done to oneself may also harm others, and destroying property deprives the community as well as oneself. Mill excuses those who are "incapable of self - government" from this principle, such as young children or those living in "backward states of society".

Mill argues that despotism is an acceptable form of government for those societies that are "backward", as long as the despot has the best interests of the people at heart, because of the barriers to spontaneous progress. Though this principle seems clear, there are a number of complications. For example, Mill explicitly states that "harms" may include acts of omission as well as acts of commission. Thus, failing to rescue a drowning child counts as a harmful act, as does failing to pay taxes, or failing to appear as a witness in court. All such harmful omissions may be regulated, according to Mill. By contrast, it does not count as harming someone if – without force or fraud – the affected individual consents to assume the risk: thus one may permissibly offer unsafe employment to others, provided there is no deception involved. (Mill does, however, recognize one limit to consent: society should not permit people to sell themselves into slavery). In these and other cases, it is important to keep in mind that the arguments in On Liberty are grounded on the principle of Utility, and not on appeals to natural rights.

The question of what counts as a self - regarding action and what actions, whether of omission or commission, constitute harmful actions subject to regulation, continues to exercise interpreters of Mill. It is important to emphasize that Mill did not consider giving offense to constitute "harm"; an action could not be restricted because it violated the conventions or morals of a given society.

On Liberty involves an impassioned defense of free speech. Mill argues that free discourse is a necessary condition for intellectual and social progress. We can never be sure, he contends, that a silenced opinion does not contain some element of the truth. He also argues that allowing people to air false opinions is productive for two reasons. First, individuals are more likely to abandon erroneous beliefs if they are engaged in an open exchange of ideas. Second, by forcing other individuals to re-examine and re-affirm their beliefs in the process of debate, these beliefs are kept from declining into mere dogma. It is not enough for Mill that one simply has an unexamined belief that happens to be true; one must understand why the belief in question is the true one.

Mill believed that "the struggle between Liberty and Authority is the most conspicuous feature in the portions of history." For him, liberty in antiquity was a "contest... between subjects, or some classes of subjects, and the government." Mill defined "social liberty" as protection from "the tyranny of political rulers." He introduced a number of different tyrannies, including social tyranny, and also the tyranny of the majority.

Social liberty for Mill meant putting limits on the ruler's power so that he would not be able to use his power on his own wishes and make decisions which could harm society; in other words, people should have the right to have a say in the government's decisions. He said that social liberty was "the nature and limits of the power which can be legitimately exercised by society over the individual". It was attempted in two ways: first, by obtaining recognition of certain immunities, called political liberties or rights; second, by establishment of a system of "constitutional checks".

However, in Mill's view, limiting the power of government was not enough. He stated, "Society can and does execute its own mandates: and if it issues wrong mandates instead of right, or any mandates at all in things with which it ought not to meddle, it practices a social tyranny more formidable than many kinds of political oppression, since, though not usually upheld by such extreme penalties, it leaves fewer means of escape, penetrating much more deeply into the details of life, and enslaving the soul itself."

John Stuart Mill's view on liberty, which was influenced by Joseph Priestley and Josiah Warren, is that the individual ought to be free to do as he wishes unless he harms others. Individuals are rational enough to make decisions about their good being and choose any religion they want to. Government should interfere when it is for the protection of society. Mill explains,

"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. That the only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not sufficient warrant. He cannot rightfully be compelled to do or forbear because it will be better for him to do so, because it will make him happier, because, in the opinion of others, to do so would be wise, or even right... The only part of the conduct of anyone, for which he is amenable to society, is that which concerns others. In the part which merely concerns him, his independence is, of right, absolute. Over himself, over his own body and mind, the individual is sovereign." And yet immediately prior to the above referenced paragraph, Mill also explains, "There is, in fact, no recognized principle by which the propriety or impropriety of government interference is customarily tested. People decide according to their personal preferences. Some, whenever they see any good to be done, or evil to be remedied, would willingly instigate the government to undertake the business; while others prefer to bear almost any amount of social evil, rather than add one to the departments of human interests amenable to governmental control.", thus, highlighting the highly contestable nature of liberty in the sense of its relationship to conceptions of both positive and negative rights.

An influential advocate of freedom of speech, Mill objected to censorship. He says: "I choose, by preference the cases which are least favorable to me – In which the argument against freedom of opinion, both on truth and that of utility, is considered the strongest. Let the opinions impugned be the belief of God and in a future state, or any of the commonly received doctrines of morality... But I must be permitted to observe that it is not the feeling sure of a doctrine (be it what it may) which I call an assumption of infallibility. It is the undertaking to decide that question for others, without allowing them to hear what can be said on the contrary side. And I denounce and reprobate this pretension not the less if it is put forth on the side of my most solemn convictions. However, positive anyone's persuasion may be, not only of the faculty but of the pernicious consequences, but (to adopt expressions which I altogether condemn) the immorality and impiety of opinion. – yet if, in pursuance of that private judgement, though backed by the public judgement of his country or contemporaries, he prevents the opinion from being heard in its defense, he assumes infallibility. And so far from the assumption being less objectionable or less dangerous because the opinion is called immoral or impious, this is the case of all others in which it is most fatal."

Mill outlines the benefits of 'searching for and discovering the truth' as a way to further knowledge. He argued that even if an opinion is false, the truth can be better understood by refuting the error. And as most opinions are neither completely true nor completely false, he points out that allowing free expression allows the airing of competing views as a way to preserve partial truth in various opinions. Worried about minority views being suppressed, Mills also argued in support of freedom of speech on political grounds, stating that it is a critical component for a representative government to have in order to empower debate over public policy. Mill also eloquently argued that freedom of expression allows for personal growth and self - realization. He said that freedom of speech was a vital way to develop talents and realize a person's potential and creativity. He repeatedly said that eccentricity was preferable to uniformity and stagnation.

In 1850, Mill sent an anonymous letter (which came to be known under the title "The Negro Question"), in rebuttal to Thomas Carlyle's anonymous letter to Fraser's Magazine for Town and Country. Carlyle had defended slavery on grounds of genetic inferiority and claimed that the West Indies development was due to British ingenuity alone and dismissed any notion that there was a debtedness to imported slaves for building the economy there. Mill's rebuttal and references to the ongoing debate in the US at the time regarding slavery were emphatic and eloquent.

Mill saw women's issues as important and began to write in favor of greater rights for women. With this, Mill can be considered among the earliest feminists. In his article, "The Subjection of Women" (1861, published 1869), Mill attempts to prove that the legal subjugation of women is wrong and that it should give way to perfect equality. He talks about the role of women in marriage and how he felt it needed to be changed. There, Mill comments on three major facets of women's lives that he felt are hindering them: society and gender construction, education, and marriage. Mill is also famous for being one of the earliest and strongest supporters of ever greater rights for women. His book The Subjection of Women is one of the earliest written on this subject by a male author. He felt that the oppression of women was one of the few remaining relics from ancient times, a set of prejudices that severely impeded the progress of humanity.

Mill's ideas were opposed by Ernest Belfort Bax in his treatise, 'The Legal Subjugation of Men'.

The canonical statement of Mill's utilitarianism can be found in Utilitarianism. This philosophy has a long tradition, although Mill's account is primarily influenced by Jeremy Bentham and Mill's father James Mill.

Mill's famous formulation of utilitarianism is known as the "greatest - happiness principle". It holds that one must always act so as to produce the greatest aggregate happiness among all sentient beings, within reason. Mill's major contribution to utilitarianism is his argument for the qualitative separation of pleasures. Bentham treats all forms of happiness as equal, whereas Mill argues that intellectual and moral pleasures (higher pleasures) are superior to more physical forms of pleasure (lower pleasures). Mill distinguishes between happiness and contentment, claiming that the former is of higher value than the latter, a belief wittily encapsulated in the statement that "it is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied. And if the fool, or the pig, are of a different opinion, it is because they only know their own side of the question."

Mill defines the difference between higher and lower forms of happiness with the principle that those who have experienced both tend to prefer one over the other. This is, perhaps, in direct contrast with Bentham's statement that "Quantity of pleasure being equal, push - pin is as good as poetry", that, if a simple child's game like hopscotch causes more pleasure to more people than a night at the opera house, it is more imperative upon a society to devote more resources to propagating hopscotch than running opera houses. Mill's argument is that the "simple pleasures" tend to be preferred by people who have no experience with high art, and are therefore not in a proper position to judge.

Mill supported legislation that would have granted extra voting power to university graduates on the grounds that they were in a better position to judge what would be best for society. (For he believed that education itself, not the intrinsic nature of educated people, qualified them to have more influence in government.)

The qualitative account of happiness that Mill advocates thus sheds light on his account presented in On Liberty. As Mill suggests in that text, utility is to be conceived in relation to humanity "as a progressive being", which includes the development and exercise of rational capacities as we strive to achieve a "higher mode of existence". The rejection of censorship and paternalism is intended to provide the necessary social conditions for the achievement of knowledge and the greatest ability for the greatest number to develop and exercise their deliberative and rational capacities.

Mill's early economic philosophy was one of free markets. However, he accepted interventions in the economy, such as a tax on alcohol, if there were sufficient utilitarian grounds. He also accepted the principle of legislative intervention for the purpose of animal welfare. Mill originally believed that "equality of taxation" meant "equality of sacrifice" and that progressive taxation penalized those who worked harder and saved more and was therefore "a mild form of robbery".

Given an equal tax rate regardless of income, Mill agreed that inheritance should be taxed. A utilitarian society would agree that everyone should be equal one way or another. Therefore receiving inheritance would put one ahead of society unless taxed on the inheritance. Those who donate should consider and choose carefully where their money goes — some charities are more deserving than others. Considering public charities boards such as a government will disperse the money equally. However, a private charity board like a church would disperse the monies fairly to those who are in more need than others.

Later he altered his views toward a more socialist bent, adding chapters to his Principles of Political Economy in defense of a socialist outlook, and defending some socialist causes. Within this revised work he also made the radical proposal that the whole wage system be abolished in favor of a co-operative wage system. Nonetheless, some of his views on the idea of flat taxation remained, albeit in a slightly toned down form.

Mill's Principles of Political Economy, first published in 1848, was one of the most widely read of all books on economics in the period. As Adam Smith's Wealth of Nations had during an earlier period, Mill's Principles dominated economics teaching. In the case of Oxford University it was the standard text until 1919. The text that replaced it was written by Cambridge's Alfred Marshall.

Mill promoted economic democracy in the capitalist economy whereby laborers would elect members of management.

Mill demonstrated an early insight into the value of the natural world – in particular in Book IV, chapter VI of "Principles of Political Economy": "Of the Stationary State" in which Mill recognized wealth beyond the material, and argued that the logical conclusion of unlimited growth was destruction of the environment and a reduced quality of life. He concluded that a stationary state could be preferable to never - ending economic growth:

I cannot, therefore, regard the stationary state of capital and wealth with the unaffected aversion so generally manifested towards it by political economists of the old school.

If the earth must lose that great portion of its pleasantness which it owes to things that the unlimited increase of wealth and population would extirpate from it, for the mere purpose of enabling it to support a larger, but not a better or a happier population, I sincerely hope, for the sake of posterity, that they will be content to be stationary, long before necessity compel them to it.

Mill regarded economic development as a function of land, labor and capital. While land and labor are the two original factors of production, capital is "a stock, previously accumulated of the products of former labor." Increase in wealth is possible only if land and capital help to increase production faster than the labor force. It is productive labor that is productive of wealth and capital accumulation. "The rate of capital accumulation is the function of the proportion of the labor force employed ' productively. Profits earned by employing unproductive labors are merely transfers of income; unproductive labor does not generate wealth or income" . It is productive laborers who do productive consumption. Productive consumption is that "which maintains and increase the productive capacity of the community." It implies that productive consumption is an input necessary to maintain productive laborers.

Mill supported the Malthusian theory of population. By population he meant the number of the working class only. He was therefore concerned about the growth in number of laborers who worked for hire. He believed that population control was essential for improving the condition of the working class so that they might enjoy the fruits of the technological progress and capital accumulation. He propagated birth control as against moral restraint.

According to Mill, the elasticity of supply is very high in response to high in wages. Wages generally exceed the minimum subsistence level. Wages are paid out of capital. Hence they are limited by existing fund of capital meant for paying wages. Thus wage per head can be derived at by dividing the total circulating capital by working population. Wages can increase by an increase in the aggregate fund of capital employed in hiring labor or by decrease in the number of the worker. If wages rise, supply of labor will be high. Competition among workers will not only bring down wages but also keep some laborers out of employment. This is based on Mill's notion that" Demand for commodities is not demand for laborers." It means income invested as advances of wages to labor creates employment and not income spent on consumer goods. An increase in consumption will mean a decline in investment. So increase in investment leads to increase in the wage fund and economic progress.

According to Mill the rate of capital accumulation depends upon: (1) "the amount of fund from which saving can be made" or" the size of the net produce of the industry "and (2) "the strength of disposition to save. "Capital is the result of savings, and the savings come from the "abstinence from present consumption for the sake of future goods". Although capital is the result of saving, it is nevertheless consumed. This means savings is spending. Since saving depends on the net produce of the industry, they increase with an increase in profits and rent which goes into making the net produce. On the other hand the strength of the disposition to save depends upon (1) the rate of profit and (2) the desire to save or what Mill called "effective desire of accumulation." For Mill, profits depends on cost of labor. So rate of profits is the ratio of profits to wages. When profits rise or wages fall, the rate of profits increases which in turn increases the rate of capital accumulation. Similarly, it is the desire to save which tends to increase the rate of capital accumulation.

According to Mill, the ultimate tendency in an economy is for the rate of profit to decline due to diminishing returns in agriculture and increase in population at a Malthusian rate.
