Jeremy Bentham (IPA: ['benθəm] or ['bentəm]) (February 15, 1748 O.S. (February 26, 1749 N.S.) – June 6, 1832) was an English jurist, philosopher, and legal and social reformer. He was a political radical and a leading theorist in Anglo-American philosophy of law. He is best known as an early advocate of utilitarianism and animal rights  who influenced the development of liberalism.
Bentham was one of the most influential utilitarians, partially through his writings but particularly through his students all around the world. These included his secretary and collaborator on the utilitarian school of philosophy James Mill, James Mill's son John Stuart Mill, and several political leaders (and Robert Owen, who later became the founder of socialism).
He argued in favour of individual and economic freedom, including the separation of church and state, freedom of expression, equal rights for women, animal rights, the end of slavery, the abolition of physical punishment (including that of children), the right to divorce, free trade, and in defence of usury  and homosexuality.  He supported inheritance tax, restrictions on monopoly power, pensions, and health insurance.
Bentham was born in Spitalfields, London, into a wealthy Tory family. He was a child prodigy and was found as a toddler sitting at his father's desk reading a multi-volume history of England. He began his study of Latin at the age of three.
He went to Westminster School, and in 1760 his father sent him to The Queen's College, Oxford, where he took his Bachelor's degree in 1763 and his Master's degree in 1766. He trained as a lawyer and (though he never practised) was called to the bar in 1769. He became deeply frustrated with the complexity of the English legal code, which he termed the "Demon of Chicane".
Among his many proposals for legal and social reform was a design for a prison building he called the Panopticon. Although it was never built, the idea had an important influence upon later generations of thinkers. Twentieth-century French philosopher Michel Foucault argued that the Panopticon was paradigmatic of a whole raft of nineteenth-century 'disciplinary' institutions.
Bentham was in correspondence with many influential people. Adam Smith, for example, had opposed free interest rates before Bentham's arguments convinced him on the subject. As a result of his correspondence with Mirabeau and other leaders of the French Revolution, he was declared an honorary citizen of France, but Bentham was a violent critic of the revolutionary discourse of natural rights, and of the violence which arose after the Jacobins took power (1792).
In 1823, he co-founded the Westminster Review with John Stuart Mill as a journal for the ".
Bentham is frequently associated with the foundation of the University of London, specifically University College London (UCL), though in fact he was 78 years old when UCL opened in 1826, and played no active part in its establishment. However, it is likely that without his inspiration, UCL would not have been created when it was. Bentham strongly believed that education should be more widely available, particularly to those who were not wealthy or who did not belong to the established church, both of which were required of students by Oxford and Cambridge. As UCL was the first English university to admit all, regardless of race, creed, or political belief, it was largely consistent with Bentham's vision, and he oversaw the appointment of one of his pupils, John Austin, as the first Professor of Jurisprudence in 1829.
As requested in his will, his body was preserved and stored in a wooden cabinet, termed his "Auto-Icon," at University College London. The Auto-Icon is kept on public display at the end of the South Cloisters in the main building of the College. The Auto-Icon is occasionally brought to meetings of the Council (at which Bentham is listed on the roll as "present but not voting") so that his eccentric presence can live on.
The Auto-Icon has always had a wax head, as Bentham's head was badly damaged in the preservation process. The real head was displayed in the same case for many years, but became the target of repeated student pranks including being stolen on more than one occasion. It is now locked away securely.
There is a plaque on Queen Anne's Gate, Westminster commemorating the house where Bentham lived, which at the time was called Queen's Square Place.
Bentham has a complicated publishing history. Most of his writing was never published in his own lifetime; much of that which was published (see this list of published works) was prepared for publication by others.
Works published in Bentham's lifetime included:
The essay Offences Against One's Self: Paederasty, which argued for the liberalisation of laws prohibiting same-sex attraction, egalitarian as well as pederastic, remained unpublished during his lifetime for fear of offending public morality. It was finally published for the first time in 1978 (summer and fall issues of Journal of Homosexuality).Text of the essay
Several of Bentham's works appeared first in French translation, prepared for the press by Étienne Dumont. Some made their first appearance in English in the 1820s as a result of back-translation from Dumont's 1802 collection (and redaction) of Bentham's writing on civil and penal legislation.
John Bowring, a British politician who had been Bentham's trusted friend, was appointed his literary executor and charged with the task of preparing a collected edition of his works. This appeared in 11 volumes in 1838-1843: Bowring based his edition on previously published editions (including those of Dumont) rather than Bentham's own manuscripts, and did not reprint Bentham's works on religion at all.
Bentham left manuscripts amounting to some 5,000,000 words. Since 1968, the Bentham Project at University College London have been busy working on an edition of his collected work. So far, 25 volumes have appeared; there may be as many still to come before the project is completed.
Bentham not only proposed many legal and social reforms, but also expounded a moral principle on which they should be based. This philosophy, utilitarianism, argued that the right act or policy was that which would cause "the greatest happiness of the greatest number" — a phrase of which he is generally, though erroneously, regarded as the author — though he later dropped the second qualification and embraced what he called "the greatest happiness principle," - often referred to as the principle of utility. He wrote that: "Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do, as well as to determine what we shall do. On the one hand the standard of right and wrong, on the other the chain of causes and effects, are fastened to their throne. They govern us in all we do, in all we say, in all we think..." (Chp. I, p. 1, The Principles of Morals and Legislation, 1789). He attributed his theory to Joseph Priestley: "Priestley was the first (unless it was Beccaria) who taught my lips to pronounce this sacred truth:- That the greatest happiness of the greatest number is the foundation of morals and legislation." )
He also suggested a procedure for estimating the moral status of any action, which he called the Hedonic or felicific calculus. Utilitarianism was revised and expanded by Bentham's student, John Stuart Mill. In Mill's hands, "Benthamism" became a major element in the liberal conception of state policy objectives.
It is often said that Bentham's theory, unlike Mill's, faces the problem of lacking a principle of fairness embodied in a conception of justice. Thus, some critics object, it would be moral, for example, to torture one person if this would produce an amount of happiness in other people outweighing the unhappiness of the tortured individual. (Compare "The Ones Who Walk Away From Omelas".) However, as P. J. Kelly argued in his book Utilitarianism and Distributive Justice: Jeremy Bentham and the Civil Law, Bentham had a theory of justice that prevented such consequences. According to Kelly, for Bentham the law "provides the basic framework of social interaction by delimiting spheres of personal inviolability within which individuals can form and pursue their own conceptions of well-being." (ibid, p. 81) They provide security, a precondition for the formation of expectations. As the hedonic calculus shows "expectation utilities" to be much higher than natural ones, it follows that Bentham does not favour the sacrifice of a few to the benefit of the many.
His opinions about monetary economics were totally different from those of Ricardo; however, they had some similarities to those of Thornton. He focused on monetary expansion as a means to full employment. He was also aware of the relevance of forced saving, propensity to consume, the saving-investment relationship and other matters which form the content of modern income and employment analysis. His monetary view was close to the fundamental concepts employed in his model of utilitarian decision making. Bentham stated that pleasures and pains can be ranked according to their value or “dimension” such as intensity, duration, certainty of a pleasure or a pain. He was concerned with maxima and minima of pleasures and pains, and they set a precedent for the future employment of the maximization principle in the economics of the consumer, the firm and the search for an optimum in welfare economics. (Spiegel, p.341-343)
Bentham is widely recognised as one of the earliest proponents of animal rights. He argued that animal pain is very similar to human pain, and that "[t]he day may come when the rest of the animal creation may acquire those rights which never could have been witholden from them but by the hand of tyranny."  Bentham argued that the ability to suffer, not the ability to reason, must be the benchmark of how we treat other beings. If the ability to reason were the criterion, many human beings, including babies and disabled people, would also have to be treated as though they were things. He wrote:
It may one day come to be recognised that the number of the legs, the villosity of the skin, or the termination of the os sacrum are reasons equally insufficient for abandoning a sensitive being to the same fate.
What else is it that should trace the insuperable line? Is it the faculty of reason or perhaps the faculty of discourse? But a full-grown horse or dog is beyond comparison a more rational, as well as more conversable animal, than an infant of a day or a week or even a month old. But suppose they were otherwise, what would it avail? The question is not, Can they reason?, nor Can they talk? but, Can they suffer? Why should the law refuse its protection to any sensitive being? The time will come when humanity will extend its mantle over everything which breathes ... 
Bentham's ideas were severely criticised by, among others, free market economist Murray Rothbard in his essay, Jeremy Bentham: The Utilitarian as Big Brother published in his work, Classical Economics. The Canadian author Brebner wrote in 1948 that "British laissez faire was a political and economic myth...Jeremy Bentham and John Stuart Mill, who have been commonly represented as typical, almost fundamental, formulators of laissez faire, were in fact the opposite, that is, the formulator of state intervention for collectivist ends and his devout apostle."
