Joseph Priestley (13 March 1733 (Old Style) – 6 February 1804) was an 18th-century British theologian, Dissenting clergyman, natural philosopher, educator, and political theorist who published over 150 works.

During his lifetime, Priestley's considerable scientific reputation rested on his invention of soda water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). However, Priestley's determination to defend phlogiston theory and to reject what would become the Chemical Revolution eventually left him isolated within the scientific community. The phlogiston theory (from the Ancient Greek φλογιστόν phlŏgistón "burning up" from φλόξ phlóx "fire" first stated The Chemical Revolution, also called the first chemical revolution, denotes the reformulation of Chemistry based on the Law of Conservation of Matter and
Priestley's science was integral to his theology, and he consistently tried to fuse Enlightenment rationalism with Christian theism. The Age of Enlightenment or The Enlightenment is a term used to describe a phase in Western philosophy and cultural life centered upon the eighteenth century [3] In his metaphysical texts, Priestley attempted to combine theism, materialism, and determinism, a project that has been called "audacious and original". Theism, in its most inclusive usage is the belief in at least one Deity. The Philosophy of materialism holds that the only thing that can be truly proven to exist is Matter, and is considered a form of Physicalism. Determinism is the philosophical Proposition that every event including human cognition and behaviour decision and action is causally determined [4] He believed that a proper understanding of the natural world would promote human progress and eventually bring about the Christian Millennium. This is an article on sociological Millennialism You may be looking for the article on Christian Premillennialism. [4] Priestley, who strongly believed in the free and open exchange of ideas, advocated toleration and equal rights for religious Dissenters, which also led him to help found Unitarianism in England. Religious toleration is the condition of accepting or permitting others' religious beliefs and practices which disagree with one's own English Dissenters were Christians who separated from the Church of England. Unitarianism as a theology is the belief in the single personality of God in contrast to the doctrine of the Trinity (three persons in one God Unitarianism, both as a theology and as a denominational family of churches was first defined and developed within the Protestant Reformation, although theological ancestors The controversial nature of Priestley's publications combined with his outspoken support of the French Revolution aroused public and governmental suspicion; he was eventually forced to flee to the United States after a mob burned down his home and church in 1791.

A scholar and teacher throughout his life, Priestley also made significant contributions to pedagogy, including the publication of a seminal work on English grammar and the invention of modern historiography. Pedagogy (ˈpɛdəgɒdʒi or paedagogy is the Art or Science of being a Teacher. Grammar is the field of Linguistics that covers the Rules governing the use of any given natural language. These educational writings were some of Priestley's most popular works. It was his metaphysical works, however, that had the most lasting influence: leading philosophers including Jeremy Bentham, John Stuart Mill, and Herbert Spencer credit them among the primary sources for utilitarianism. Jeremy Bentham ( IPA: or) (15 February 1748&ndash6 June 1832 was an English Jurist, Philosopher, and legal and Social reformer John Stuart Mill (20 May 1806 &ndash 8 May 1873 British Philosopher, political economist, civil servant and Member of Parliament, was an influential Herbert Spencer ( April 27, 1820 – December 8, 1903) was an English Philosopher; prominent classical liberal Utilitarianism is the idea that the moral worth of an action is solely determined by its contribution to overall Utility, that is its contribution to happiness

Priestley was born to an established English Dissenting family (i.

The Church of England is the officially established Christian church in England, the Mother Church of the worldwide Anglican The West Riding of Yorkshire is one of the three historic subdivisions of Yorkshire, England. He was the oldest of the six children born to Mary Swift and Jonas Priestley, a finisher of cloth. To ease his mother's burdens, Priestley was sent to live with his grandfather around the age of one; after his mother died five years later, he returned home. When his father remarried in 1741, Priestley went to live with his aunt and uncle, the wealthy and childless Sarah and John Keighley. Because Priestley was precocious—at the age of four he could flawlessly recite all 107 questions and answers of the Westminster Shorter Catechism—his aunt sought the best education for the boy, intending him for the ministry. The Westminster Shorter Catechism (also known simply as the Shorter Catechism hereinafter referred to as the WSC) was written in the 1640s During his youth, Priestley attended local schools where he learned Greek, Latin, and Hebrew. [6]
Around 1749, Priestley became seriously ill and believed he was dying. Raised as a devout Calvinist, he believed a conversion experience was necessary for salvation, but doubted he had had one. Calvinism (sometimes called the Reformed tradition, the Reformed faith, or Reformed theology) is a theological system and an approach to the Conversion to Christianity is the Religious conversion of a previously non-Christian person to some form of Christianity. This emotional distress eventually led him to question his theological upbringing, causing him to reject election and to accept universal salvation. Unconditional election is the Calvinist teaching that before God created the world he chose to save some people according to his own purposes and apart from any conditions Universal reconciliation, also called universal salvation or sometimes simply universalism, is the Christian doctrine or belief that all will receive Salvation As a result, the elders of his home church refused him admission as a full member. [7]
Priestley's illness left him with a permanent stutter and he gave up any thoughts of entering the ministry at that time. In preparation for joining a relative in trade in Lisbon, he studied French, Italian, and German in addition to Chaldean, Syrian, and Arabic. Lisbon (Lisboa liʒˈboɐ is the Capital and largest city of Portugal. Chaldean Neo-Aramaic is a Northeastern Neo-Aramaic language Chaldean Neo-Aramaic is spoken on the Plain of Mosul in northern Iraq, as well as by the He was tutored by the Reverend George Haggerstone, who first introduced him to higher mathematics, natural philosophy, logic, and metaphysics through the works of Isaac Watts, Willem 's Gravesande, and John Locke. For the current in the 19th century German idealism see Naturphilosophie Natural philosophy or the philosophy of nature (from Metaphysics is the branch of Philosophy investigating principles of reality transcending those of any particular science Isaac Watts ( July 17, 1674 – November 25, 1748) is recognised as the "Father of English Hymnody" as he was the first prolific and Willem Jacob 's Gravesande ( September 26, 1688 – February 28, 1742) was a Dutch Philosopher and Mathematician John Locke (29 August 1632 – 28 October 1704 was an English Philosopher. [8]
Priestley eventually decided to return to his theological studies and, in 1752, matriculated at Daventry, a Dissenting academy. [9] Because he had already read widely, Priestley was allowed to skip the first two years of coursework. He continued his intense study; this, together with the liberal atmosphere of the school, shifted his theology further leftward and he became a Rational Dissenter. English Dissenters were Christians who separated from the Church of England. Abhorring dogma and religious mysticism, Rational Dissenters emphasized the rational analysis of the natural world and the Bible. [10]
Priestley later wrote that the book that influenced him the most, save the Bible, was David Hartley's Observations on Man (1749). David Hartley (June 21 1705&ndashAugust 28 1757 was an English philosopher and founder of the Associationist school of Psychology Observations on Man his Frame his Duty and his Expectations is eighteenth-century British philosopher David Hartley's major work Hartley's psychological, philosophical, and theological treatise postulated a material theory of mind. Philosophy of mind is the branch of Philosophy that studies the nature of the Mind, Mental events Mental functions mental properties Hartley aimed to construct a Christian philosophy in which both religious and moral "facts" could be scientifically proven, a goal that would occupy Priestley for his entire life. In his third year at Daventry, Priestley committed himself to the ministry, which he described as "the noblest of all professions". [11]
Robert Schofield, Priestley's major modern biographer, describes his first "call" in 1755 to the Dissenting parish in Needham Market, Suffolk, as a "mistake" for both Priestley and the congregation. The Rudiments of English Grammar (1761 was a popular English grammar textbook written the eighteenth-century British Polymath Joseph Priestley Joseph Priestley ( &ndash February 8 1804) was a British Natural philosopher, Dissenting Clergyman, political Needham Market is a Town in Suffolk, England. It initially grew around the Wool combing industry until the onset of the plague, which Suffolk (ˈsʌfək is a non-metropolitan county of historic origin in East Anglia, England. [12] Priestley yearned for urban life and theological debate, whereas Needham Market was a small, rural town with a congregation wedded to tradition. Attendance and donations dropped sharply when they discovered the extent of his heterodoxy. Heterodoxy includes "any opinions or doctrines at variance with an official or orthodox position" Although Priestley's aunt had promised her support if he became a minister, she refused any further assistance when she realized he was no longer a Calvinist. Calvinism (sometimes called the Reformed tradition, the Reformed faith, or Reformed theology) is a theological system and an approach to the To earn extra money, Priestley proposed opening a school, but local families informed him that they would refuse to send their children. He also presented a series of scientific lectures titled "Use of the Globes" that was more successful. [13]
Priestley's Daventry friends helped him obtain another position and in 1758 he moved to Nantwich, Cheshire; his time there was happier. Nantwich is a market town in south Cheshire, England, in the Borough and parliamentary constituency of Crewe and Nantwich. Cheshire (or archaically the County of Chester) is a county in North West England. The congregation cared less about Priestley's heterodoxy and he successfully established a school. Unlike many schoolmasters of the time, Priestley taught his students natural philosophy and even bought scientific instruments for them. For the current in the 19th century German idealism see Naturphilosophie Natural philosophy or the philosophy of nature (from Appalled at the quality of the available English grammar books, Priestley wrote his own: The Rudiments of English Grammar (1761). The Rudiments of English Grammar (1761 was a popular English grammar textbook written the eighteenth-century British Polymath Joseph Priestley [14] His innovations in the description of English grammar, particularly his efforts to disassociate it from Latin grammar, led 20th-century scholars to describe him as "one of the great grammarians of his time". Grammar is the field of Linguistics that covers the Rules governing the use of any given natural language. [15] After the publication of Rudiments and the success of Priestley's school, Warrington Academy offered him a teaching position in 1761. Warrington Academy 1756-1786 was an early dissenters College in Warrington, Cheshire [16]
In 1761, Priestley moved to Warrington and assumed the post of tutor of modern languages and rhetoric at the town's Dissenting academy, although he would have preferred to teach mathematics and natural philosophy.

This proved a very suitable and happy connexion, my wife being a woman of an excellent understanding, much improved by reading, of great fortitude and strength of mind, and of a temper in the highest degree affectionate and generous; feeling strongly for others, and little for herself. Also, greatly excelling in every thing relating to household affairs, she entirely relieved me of all concern of that kind, which allowed me to give all my time to the prosecution of my studies, and the other duties of my station.

All of the books Priestley published while at Warrington emphasized the study of history; Priestley considered it essential for worldly success as well as religious growth. Joseph Priestley ( &ndash February 8 1804) was a British Natural philosopher, Dissenting Clergyman, political He wrote histories of science and Christianity in an effort to reveal the progress of humanity and, paradoxically, the loss of a pure, "primitive Christianity". [20]
In his Essay on a Course of Liberal Education for Civil and Active Life (1765),[22] Lectures on History and General Policy (1788), and other works, Priestley argued that the education of the young should anticipate their future practical needs. Essay on a Course of Liberal Education for Civil and Active Life (1765 is an educational treatise by the eighteenth-century British Polymath Joseph Priestley Lectures on History and General Policy (1788 is the published version of a set of lectures on history and government given by the eighteenth-century British Polymath This principle of utility guided his unconventional curricular choices for Warrington's aspiring middle-class students. He recommended modern languages instead of classical languages and modern rather than ancient history. Priestley's lectures on history were particularly revolutionary; he narrated a providentialist and naturalist account of history, arguing that the study of history furthered the comprehension of God's natural laws. Providentialism is a belief that God 's will is evident in all occurrences Furthermore, his millennial perspective was closely tied to his optimism regarding scientific progress and the improvement of humanity. This is an article on sociological Millennialism You may be looking for the article on Christian Premillennialism. He believed that each age would improve upon the previous and that the study of history allowed people to perceive and to advance this progress. Since the study of history was a moral imperative for Priestley, he also promoted the education of middle-class women, which was unusual at the time. [23] Some scholars of education have described Priestley as the most important English writer on education between the 17th-century John Locke and the 19th-century Herbert Spencer. John Locke (29 August 1632 – 28 October 1704 was an English Philosopher. Herbert Spencer ( April 27, 1820 – December 8, 1903) was an English Philosopher; prominent classical liberal [24] Lectures on History was well-received and was employed by many educational institutions, such as New College at Hackney, Brown, Princeton, Yale, and Cambridge. Brown University is a highly esteemed private University located in Providence, Rhode Island and is a member of the Ivy League. Princeton University is a private Coeducational research university located in Princeton, New Jersey. The University of Cambridge (often Cambridge University) located in Cambridge, England, is the second-oldest university in the [25] Priestley designed two Charts to serve as visual study aides for his Lectures. [26] Both were popular for decades, and the trustees of Warrington were so impressed with Priestley's lectures and charts that they arranged for the University of Edinburgh to grant him a Doctor of Law degree in 1764. The University of Edinburgh (Oilthigh Dhùn Èideann founded in 1582 is a renowned centre for teaching and research in Edinburgh, Scotland, UK. Doctor of Laws ( Latin: Legum Doctor, LLD) is a Doctorate -level Academic degree in Law. [27]
The intellectually stimulating atmosphere of Warrington, often called the "Athens of the North" during the 18th century, encouraged Priestley's growing interest in natural philosophy. He gave lectures on anatomy and performed experiments regarding temperature with another tutor at Warrington, his friend John Seddon. [29] Despite Priestley's busy teaching schedule, he decided to write a history of electricity. Friends introduced him to the major experimenters in the field in Britain—John Canton, William Watson, and the visiting Benjamin Franklin—who encouraged Priestley to perform the experiments he wanted to include in his history. John Canton ( July 31, 1718 &ndash March 22, 1772) was an English Physicist. William Watson ( 3 April 1715 &ndash 10 May 1787) was an English physician and scientist who was born and died in London Benjamin Franklin ( April 17 1790 was one of the Founding Fathers of the United States of America. In the process of replicating others' experiments, Priestley became intrigued by unanswered questions and was prompted to undertake experiments of his own design. [30] (Impressed with his Charts and the manuscript of his history of electricity, Canton, Franklin, Watson, and Richard Price nominated Priestley for a fellowship in the Royal Society; he was accepted in 1766. Richard Price ( February 23, 1723 &ndash April 19, 1791) was a Welsh moral and political philosopher The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 )[31]
In 1767, the 700-page The History and Present State of Electricity was published to positive reviews. [32] The first half of the text is a history of the study of electricity to 1766; the second and more influential half is a description of contemporary theories about electricity and suggestions for future research. Priestley reported some of his own discoveries in the second section, such as the conductivity of charcoal and other substances and the continuum between conductors and non-conductors. Electrical conductivity or specific conductivity is a measure of a material's ability to conduct an Electric current. Charcoal' is the blackish residue consisting of impure Carbon obtained by removing water and other volatile constituents from Animal and Vegetation [33] This discovery overturned what he described as "one of the earliest and universally received maxims of electricity", that only water and metals could conduct electricity. This and other experiments on the electrical properties of materials and on the electrical effects of chemical transformations demonstrated Priestley's early and ongoing interest in the relationship between chemical substances and electricity. [34] Based on experiments with charged spheres, Priestley was also the first to propose that electrical force followed an inverse-square law, similar to Newton's law of universal gravitation. In Physics, an inverse-square law is any Physical law stating that some physical Quantity or strength is inversely proportional Newton 's law of universal Gravitation is a physical law describing the gravitational attraction between bodies with mass However, he did not generalize or elaborate on this,[33] and the general law was enunciated by French physicist Charles Augustin de Coulomb in the 1780s. ---- Bold text Coulomb's law', developed in the 1780s by French physicist Charles Augustin de Coulomb, may be stated in scalar form Charles Augustin de Cock (June 14 1736 Angoulême France – August 23 1806 Penis France was a French Physicist.
Priestley's strength as a natural philosopher was qualitative rather than quantitative and his observation of "a current of real air" between two electrified points would later interest Michael Faraday and James Clerk Maxwell as they investigated electromagnetism. Michael Faraday, FRS ( September 22 1791 – August 25 1867) was an English James Clerk Maxwell (13 June 1831 &ndash 5 November 1879 was a Scottish mathematician and theoretical physicist. Electromagnetism is the Physics of the Electromagnetic field: a field which exerts a Force on particles that possess the property of Priestley's text became the standard history of electricity for over a century; Alessandro Volta (who later invented the battery), William Herschel (who discovered infrared radiation), and Henry Cavendish (who discovered hydrogen) all relied upon it.

[35]
Perhaps prompted by Mary Priestley's ill health, or financial problems, or a desire to prove himself to the community that had rejected him in his childhood, Priestley moved with his family from Warrington to Leeds in 1767, and he became Mill Hill Chapel's minister. Leeds ( is located on the River Aire in West Yorkshire, England Two sons were born to the Priestleys in Leeds: Joseph junior on 24 July 1768 and William three years later.

Theophilus Lindsey ( 20 June 1723 OS &ndash 1808 was an English Anglican theologian who became a Unitarian. The word rector ("ruler" from the Latin regere and Rector meaning "Teacher" In Latin has a number of different meanings but all of them indicate an academic Catterick, sometimes Catterick Village to distinguish it from the nearby Catterick Garrison, is a Village in North Yorkshire. "[37] Although Priestley had extended family living around Leeds, it does not appear that they communicated. Schofield conjectures that they considered him a heretic. Heresy is an introduced change to some system of belief especially a religion that conflicts with the previously established canon of that belief [38] Each year Priestley travelled to London to consult with his close friend and publisher, Joseph Johnson, and to attend meetings of the Royal Society. Joseph Johnson (15 November 1738 – 20 December 1809 was an influential The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 [39]
When Priestley became its minister, Mill Hill Chapel was one of the oldest and most respected Dissenting congregations in England; however, during the early 18th century the congregation had fractured along doctrinal lines, and was losing members to the charismatic Methodist movement. Methodism is a movement within Protestant Christianity represented by a number of denominations and organizations [40] Priestley believed that by educating the young, he could strengthen the bonds of the congregation. [41]
In his magisterial three-volume Institutes of Natural and Revealed Religion (1772–74),[42] Priestley outlined his theories of religious instruction. The Institutes of Natural and Revealed Religion, written by eighteenth-century British Dissenting minister and Polymath Joseph Priestley More importantly, he laid out his belief in Socinianism. Socinianism is a form of Antitrinitarianism, named for Laelius Socinus (died 1562 in Zürich) and of his nephew Faustus Socinus The doctrines he explicated would become the standards for Unitarians in Britain. This work marked a change in Priestley's theological thinking that is critical to understanding his later writings—it paved the way for his materialism and necessitarianism (the belief that a divine being acts in accordance with necessary metaphysical laws). The Philosophy of materialism holds that the only thing that can be truly proven to exist is Matter, and is considered a form of Physicalism. Necessitarianism is a metaphysical principle that denies all mere possibility there is exactly one way for the world to be [43]
Priestley's major argument in the Institutes was that the only revealed religious truths that could be accepted were those that matched one's experience of the natural world. Because his views of religion were deeply tied to his understanding of nature, the text's theism rested on the argument from design. Theism, in its most inclusive usage is the belief in at least one Deity. A teleological argument, or argument from design, is an Argument for the Existence of God or a creator based on perceived evidence of order purpose design [44] The Institutes shocked and appalled many readers, primarily because it challenged basic Christian orthodoxies, such as the divinity of Christ and the miracle of the Virgin Birth. Christ is the English term for the Greek ( Khristós) meaning "the anointed " The virgin birth of Jesus is a religious Tenet of Christianity and Islam which holds that Mary miraculously conceived Jesus while Methodists in Leeds penned a hymn asking God to "the Unitarian fiend expel / And chase his doctrine back to Hell. "[45] Priestley wanted to return Christianity to its "primitive" or "pure" form by eliminating the "corruptions" which had accumulated over the centuries. The fourth part of the Institutes, An History of the Corruptions of Christianity, became so long that he was forced to issue it separately in 1782. An History of the Corruptions of Christianity, published by Joseph Johnson in 1782 was the fourth part of eighteenth-century Dissenting minister Joseph Priestley believed that the Corruptions was "the most valuable" work he ever published. In demanding that his readers apply the logic of the emerging sciences and comparative history to the Bible and Christianity, he alienated religious and scientific readers alike—scientific readers did not appreciate seeing science used in the defence of religion and religious readers dismissed the application of science to religion. [46]
Priestley engaged in numerous political and religious pamphlet wars. A pamphlet is an unbound Booklet (that is without a hard cover or binding) According to Schofield, "he entered each controversy with a cheerful conviction that he was right, while most of his opponents were convinced, from the outset, that he was willfully and maliciously wrong. He was able, then, to contrast his sweet reasonableness to their personal rancor. "[47] However, as Schofield points out, Priestley rarely altered his opinion as a result of these debates. [47] While at Leeds, he wrote controversial pamphlets on the Lord's Supper and on Calvinist doctrine; thousands of copies were published, making them some of Priestley's most widely-read works. The Eucharist, also called Holy Communion or Lord's Supper and other names is a Christian Sacrament by which in a common interpretation those Calvinism (sometimes called the Reformed tradition, the Reformed faith, or Reformed theology) is a theological system and an approach to the [48]
Priestley founded the Theological Repository in 1768, a journal committed to the open and rational inquiry of theological questions. The Theological Repository was a periodical founded and edited from 1769 to 1771 by the eighteenth-century British Polymath Joseph Although he promised to print any contribution, only like-minded authors submitted articles. He was therefore obliged to provide much of the journal's content himself (this material became the basis for many of his later theological and metaphysical works). After only a few years, due to a lack of funds, he was forced to cease publishing the journal. [49] He revived it in 1784 with similar results. [50]
Many of Priestley's political writings supported the repeal of the Test and Corporation Acts, which restricted the rights of Dissenters. Joseph Priestley ( March 13, 1733 ( old style) &ndash February 8, 1804) was a British Natural philosopher The Test Acts were a series of English Penal laws that served as a Religious test for public office and imposed various civil disabilities on Roman The Corporation Act of 1661 is an Act of the Parliament of England (13 Cha They could not hold political office, serve in the armed forces, or attend Oxford and Cambridge unless they subscribed to the Thirty-nine Articles of the Church of England. The Thirty-Nine Articles of Religion were established in 1563 and are the historic defining statements of Anglican doctrine in relation to the controversies of the The Church of England is the officially established Christian church in England, the Mother Church of the worldwide Anglican Dissenters repeatedly petitioned Parliament to repeal the Acts, arguing that they were being treated as second-class citizens. [52]
Priestley's friends, particularly other Rational Dissenters, urged him to publish a work on the injustices experienced by Dissenters; the result was his Essay on the First Principles of Government (1768). Essay on the First Principles of Government (1768 is an early work of modern liberal political theory by eighteenth-century British Polymath [53] An early work of modern liberal political theory and Priestley's most thorough treatment of the subject, it—unusually for the time—distinguished political rights from civil rights with precision and argued for expansive civil rights. Liberalism is a broad array of related ideas and theories of Government that consider individual Liberty to be the most important political goal Priestley identified separate private and public spheres, contending that the government should only have control over the public sphere. Education and religion, in particular, he maintained, were matters of private conscience and should not be administered by the state. Priestley's later radicalism emerged from his belief that the British government was infringing upon these individual freedoms. [54]
Priestley also defended the rights of Dissenters against the attacks of William Blackstone, an eminent legal theorist, whose Commentaries on the Laws of England (1765–69) had become the standard legal guide. Sir William Blackstone (originally pronounced Blexstun ( 10 July 1723 &ndash 14 February 1780) was an English Jurist and The Commentaries on the Laws of England are an influential 18th century treatise on the Common law of England by Sir William Blackstone, originally Blackstone's book stated that dissent from the Church of England was a crime and that Dissenters could not be loyal subjects. Furious, Priestley lashed out with his Remarks on Dr. Blackstone's Commentaries (1769), correcting Blackstone's interpretation of the law, his grammar (a highly politicized subject at the time), and history. [55] Blackstone, chastened, altered subsequent editions of his Commentaries: he rephrased the offending passages and removed the sections claiming that Dissenters could not be loyal subjects, but he retained his description of Dissent as a crime. [56]
Although Priestley claimed that natural philosophy was only a hobby, he took it seriously. For the current in the 19th century German idealism see Naturphilosophie Natural philosophy or the philosophy of nature (from In his History of Electricity, he described the scientist as promoting the "security and happiness of mankind". [57] Priestley's science was eminently practical and he rarely concerned himself with theoretical questions; his model was Benjamin Franklin. Benjamin Franklin ( April 17 1790 was one of the Founding Fathers of the United States of America. When he moved to Leeds, Priestley continued his electrical and chemical experiments (the latter aided by a steady supply of carbon dioxide from a neighbouring brewery). A brewery is a dedicated building for the making of Beer, though beer can be made in the home and has been for much of beer's history Between 1767 and 1770, he presented five papers to the Royal Society from these initial experiments; the first four papers explored coronal discharges and other phenomena related to electrical discharge, while the fifth reported on the conductivity of charcoals from different sources. The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 In Electricity, a corona discharge is an Electrical discharge brought on by the Ionization of a Fluid surrounding a conductor, which Electrostatic discharge ( ESD) is the sudden and momentary Electric current that flows between two objects at different Electrical potentials The term is His subsequent experimental work focused on chemistry and pneumatics.

Priestley published the first volume of his projected history of experimental philosophy, The History and Present State of Discoveries Relating to Vision, Light and Colours (referred to as his Optics), in 1772. [59] He paid careful attention to the history of optics and presented excellent explanations of early optics experiments, but his mathematical deficiencies caused him to dismiss several important contemporary theories. Furthermore, he did not include any of the practical sections that had made his History of Electricity so useful to practising natural philosophers. Unlike his History of Electricity, it was not popular and had only one edition, although it was the only English book on the topic for 150 years. The hastily written text sold poorly; the cost of researching, writing, and publishing the Optics convinced Priestley to abandon his history of experimental philosophy. [60]
Priestley was considered for the position of astronomer on James Cook's second voyage to the South Seas, but was not chosen. Captain James Cook FRS RN ( – 14 February 1779) was an English Explorer, Navigator and Captain James Cook FRS RN ( – 14 February 1779) was an English Explorer, Navigator and Still, he contributed in a small way to the voyage: he provided the crew with a method for making soda water, which he erroneously speculated might be a cure for scurvy. Scurvy (NLat scorbutus is a disease resulting from a deficiency of Vitamin C, which is required for the synthesis of Collagen in humans He then published a pamphlet with Directions for Impregnating Water with Fixed Air (1772). [61] Priestley did not exploit the commercial potential of soda water, but others such as J. J. Schweppe made fortunes from it. Cadbury plc () is a Confectionery and Beverage [62] In 1773, the Royal Society recognized Priestley's achievements in natural philosophy by awarding him the Copley Medal. The Copley Medal is a scientific award for distinguished achievement in any field of Science established by the Royal Society of London in 1731 [63]
Priestley's friends wanted to find him a more financially secure position. In 1772, prompted by Richard Price and Benjamin Franklin, Lord Shelburne wrote to Priestley asking him to direct the education of his children and to act as his general assistant. Richard Price ( February 23, 1723 &ndash April 19, 1791) was a Welsh moral and political philosopher William Petty-FitzMaurice 1st Marquess of Lansdowne, KG, PC (2 May 1737 &ndash 7 May 1805 known as The Earl of Shelburne between 1761 and 1784 by which Although Priestley was reluctant to sacrifice his ministry, he accepted the position, resigning from Mill Hill Chapel on 20 December 1772, and preaching his last sermon on 16 May 1773.

In 1773, the Priestleys moved to Calne and a year later Lord Shelburne and Priestley took a tour of Europe. Calne is a Town in central Wiltshire, England. It is situated at the southern extreme of the county's North Wiltshire * local government district William Petty-FitzMaurice 1st Marquess of Lansdowne, KG, PC (2 May 1737 &ndash 7 May 1805 known as The Earl of Shelburne between 1761 and 1784 by which According to Priestley's close friend Theophilus Lindsey, Priestley was "much improved by this view of mankind at large". Theophilus Lindsey ( 20 June 1723 OS &ndash 1808 was an English Anglican theologian who became a Unitarian. [66] Upon their return, Priestley easily fulfilled his duties as librarian and tutor. The workload was intentionally light, allowing him time to pursue his scientific investigations and theological interests. Priestley also became a political adviser to Shelburne, gathering information on parliamentary issues and serving as a liaison between Shelburne and the Dissenting and American interests.

Priestley wrote his most important philosophical works during his years with Lord Shelburne. In a series of major metaphysical texts published between 1774 and 1780—An Examination of Dr. Metaphysics is the branch of Philosophy investigating principles of reality transcending those of any particular science Reid's Inquiry into the Human Mind (1774), Hartley's Theory of the Human Mind on the Principle of the Association of Ideas (1775), Disquisitions relating to Matter and Spirit (1777), The Doctrine of Philosophical Necessity Illustrated (1777), and Letters to a Philosophical Unbeliever (1780)—he argues for a philosophy that incorporates four concepts: determinism, materialism, causation, and necessitarianism. Disquisitions relating to Matter and Spirit (1777 is a major work of Metaphysics written by eighteenth-century British Polymath Joseph Priestley The Doctrine of Philosophical Necessity (1777 is one of the major metaphysical works of eighteenth-century British Polymath Joseph Priestley Letters to a Philosophical Unbeliever (1780 is a multi-volume series of books on Metaphysics by eighteenth-century British Polymath Joseph Priestley Determinism is the philosophical Proposition that every event including human cognition and behaviour decision and action is causally determined The Philosophy of materialism holds that the only thing that can be truly proven to exist is Matter, and is considered a form of Physicalism. Causality (but not causation) denotes a necessary relationship between one event (called cause and another event (called effect) which is the direct consequence Necessitarianism is a metaphysical principle that denies all mere possibility there is exactly one way for the world to be By studying the natural world, he argued, people would learn how to become more compassionate, happy, and prosperous. [69]
Priestley strongly suggested that there is no mind-body duality, and put forth a materialist philosophy in these works; that is, one founded on the principle that everything in the universe is made of matter that we can perceive. In Philosophy of mind, dualism is a set of views about the relationship between mind and matter which begins with the claim that mental phenomena are in some He also contended that discussing the soul is impossible because it is made of a divine substance, and humanity cannot perceive the divine. Despite his separation of the divine from the mortal, this position shocked and angered many of his readers, who believed that such a duality was necessary for the soul to exist. The soul, according to many religious and philosophical beliefs is the self-awareness, or Consciousness, unique to a particular living [70]
Responding to Baron d'Holbach's Système de la Nature (1770) and David Hume's Dialogues Concerning Natural Religion (1779) as well as the works of the French philosophes, Priestley maintained that materialism and determinism could be reconciled with a belief in God. Paul-Henri Thiry baron d'Holbach ( 1723 – 1789) was a French - German Author, Philosopher and Encyclopedist. The System of Nature ( Système de la Nature) is a philosophical book by Baron d'Holbach (Paul Henri Thiry 1723-1789 David Hume (26 April 1711 25 August 1776 Scottish Philosopher, Economist, and Historian is an important figure in Western philosophy Dialogues concerning Natural Religion is a philosophical work written by the Scottish philosopher David Hume. The philosophes ( French for Philosophers ' were a group of intellectuals of the 18th century Enlightenment. He criticized those whose faith was shaped by books and fashion, drawing an analogy between the scepticism of educated men and the credulity of the masses. [71]
Maintaining that humans had no free will, Priestley argued that what he called "philosophical necessity" (akin to absolute determinism) is consonant with Christianity, a position based on his understanding of the natural world. The question of free will Determinism is the philosophical Proposition that every event including human cognition and behaviour decision and action is causally determined Like the rest of nature, man's mind is subject to the laws of causation, Priestley contended, but because a benevolent God created these laws, the world and the people in it will eventually be perfected. Evil is therefore only an imperfect understanding of the world. [72]
Although Priestley's philosophical work has been characterised as "audacious and original",[4][73] it partakes of older philosophical traditions on the problems of free will, determinism, and materialism. The question of free will Determinism is the philosophical Proposition that every event including human cognition and behaviour decision and action is causally determined The Philosophy of materialism holds that the only thing that can be truly proven to exist is Matter, and is considered a form of Physicalism. [74] For example, the 17th-century philosopher Baruch Spinoza argued for absolute determinism and absolute materialism. Baruch or Benedict de Spinoza (ברוך שפינוזה Bento de Espinosa Benedictus de Spinoza ( November 24, 1632 – February 21, [75] Like Spinoza[76] and Priestley,[77] Leibniz argued that human will was completely determined by natural laws;[78] however, unlike them, Leibniz argued for a "parallel universe" of immaterial objects (such as human souls) so arranged by God that its outcomes agree exactly with those of the material universe. [79] Leibniz[80] and Priestley[81] share an optimism that God has chosen the chain of events benevolently; however, Priestley believed that the events were leading to a glorious Millennial conclusion,[4] whereas for Leibniz the entire chain of events was optimal in and of itself, as compared with other conceivable chains of events. This is an article on sociological Millennialism You may be looking for the article on Christian Premillennialism. [82]
When Priestley's friend Theophilus Lindsey, decided to found a new Christian denomination that would not restrict its members' beliefs, Priestley and others hurried to his aid. Theophilus Lindsey ( 20 June 1723 OS &ndash 1808 was an English Anglican theologian who became a Unitarian. On 17 April 1774, Lindsey held the first Unitarian service in Britain; he had even designed his own liturgy, of which many were critical. Events 69 - After the First Battle of Bedriacum, Vitellius becomes Roman Emperor. Year 1774 ( MDCCLXXIV) was a Common year starting on Saturday (link will display the full calendar of the Gregorian calendar (or a Priestley defended his friend in the pamphlet Letter to a Layman, on the Subject of the Rev. Mr. Lindsey's Proposal for a Reformed English Church (1774),[83] claiming that only the form of worship had been altered, not its substance, and attacking those who followed religion as a fashion. Priestley attended Lindsey's church regularly in the 1770s and occasionally preached there. [84] He continued to support institutionalized Unitarianism for the rest of his life, writing several Defenses of Unitarianism and encouraging the foundation of new Unitarian chapels throughout Britain and the United States. [85]
Priestley's years in Calne were the only ones in his life dominated by scientific investigations; they were also the most scientifically fruitful. His experiments were almost entirely confined to "airs", and out of this work emerged his most important scientific texts: the six volumes of Experiments and Observations on Different Kinds of Air (1774–86). Experiments and Observations on Different Kinds of Air (1774–86 is a six-volume work published by eighteenth-century British Polymath Joseph Priestley [87][88] These experiments helped repudiate the last vestiges of the theory of four elements, which Priestley attempted to replace with his own variation of phlogiston theory. Many ancient philosophies used a set of archetypal classical "elements" to explain patterns in Nature. The phlogiston theory (from the Ancient Greek φλογιστόν phlŏgistón "burning up" from φλόξ phlóx "fire" first stated According to that 18th century theory, the combustion or oxidation of a substance corresponded to the release of a material substance, phlogiston. Redox (shorthand for reduction-oxidation reaction describes all Chemical reactions in which atoms have their Oxidation number ( Oxidation state [89]
Priestley's work on "airs" is not easily classified. As historian of science Simon Schaffer writes, it "has been seen as a branch of physics, or chemistry, or natural philosophy, or some highly idiosyncratic version of Priestley's own invention". Simon Schaffer (born 1 January 1955) was born in Brighton and was educated at Varndean Grammar School for Boys (now Varndean College) [90] Furthermore, the volumes were both a scientific and a political enterprise for Priestley, in which he argues that science could destroy "undue and usurped authority" and that government has "reason to tremble even at an air pump or an electrical machine". [91]
Volume I of Experiments and Observations on Different Kinds of Air outlined several discoveries: "nitrous air" (nitric oxide, NO); "vapor of spirit of salt", later called "acid air" or "marine acid air" (anhydrous hydrochloric acid, HCl); "alkaline air" (ammonia, NH3); "diminished" or "dephlogisticated nitrous air" (nitrous oxide, N2O); and, most famously, "dephlogisticated air" (oxygen, O2) as well as experimental findings that would eventually lead to the discovery of photosynthesis. Nitric oxide or nitrogen monoxide is a Chemical compound with Chemical formula N[[Oxygen O]] Ammonia is a compound with the formula N[[hydrogen H3]] It is normally encountered as a Gas with a characteristic pungent Odor Nitrous oxide, commonly known as " laughing gas," is a Chemical compound with the Chemical formula N 2 O. Oxygen (from the Greek roots ὀξύς (oxys (acid literally "sharp" from the taste of acids and -γενής (-genēs (producer literally begetteris the Photosynthesis is a Metabolic pathway that converts Light Energy into Chemical energy. Priestley also developed a "nitrous air test" to determine the "goodness of air". Using a pneumatic trough, he would mix nitrous air with a test sample, over water or mercury, and measure the decrease in volume—the principle of eudiometry. An eudiometer is a Laboratory glassware that measures the change in Volume of a Gas mixture following a Chemical reaction. [86] After a small history of the study of airs, he explained his own experiments in an open and sincere style. As an early biographer writes, "whatever he knows or thinks he tells: doubts, perplexities, blunders are set down with the most refreshing candour. "[92] Priestley also described his cheap and easy-to-assemble experimental apparatus; his colleagues therefore believed that they could easily reproduce his experiments. [93] Faced with inconsistent experimental results, Priestley employed phlogiston theory. This, however, led him to conclude that there were only three types of "air": "fixed", "alkaline", and "acid". Priestley dismissed the burgeoning chemistry of his day. The history of Chemistry begins with the discovery of Fire, then Metallurgy which allowed purification of metals and the making of alloys as well as the exploitation Instead, he focused on gases and "changes in their sensible properties", as had natural philosophers before him. He isolated carbon monoxide (CO), but apparently did not realize that it was a separate "air". Carbon monoxide, with the chemical formula CO is a colorless odorless tasteless yet highly toxic Gas. [94]
In August 1774 he isolated an "air" that appeared to be completely new, but he did not have an opportunity to pursue the matter because he was about to tour Europe with Shelburne. While in Paris, however, Priestley managed to replicate the experiment for others, including French chemist Antoine Lavoisier. After returning to Britain in January 1775, he continued his experiments and discovered "vitriolic acid air" (sulfur dioxide, SO2).
In March he wrote to several people regarding the new "air" that he had discovered in August. One of these letters was read aloud to the Royal Society, and a paper outlining the discovery, titled "An Account of further Discoveries in Air", was published in the Society's journal Philosophical Transactions. The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 The Philosophical Transactions of the Royal Society, or Phil Trans [95] Priestley called the new substance "dephlogisticated air" which he made in the famous experiment by focusing the sun's rays on a sample of mercuric oxide. Mercury(II oxide, also called mercuric oxide, has a formula of Hg[[oxygen O]] and a formula weight of 216 He first tested it on mice, who surprised him by surviving quite a while entrapped with the air, and then on himself, writing that it was "five or six times better than common air for the purpose of respiration, inflammation, and, I believe, every other use of common atmospherical air". [96] He had discovered oxygen gas (O2). Oxygen (from the Greek roots ὀξύς (oxys (acid literally "sharp" from the taste of acids and -γενής (-genēs (producer literally begetteris the
Priestley assembled his oxygen paper and several others into a second volume of Experiments and Observations on Air, published in 1776. He did not emphasize his discovery of "dephlogisticated air" (leaving it to Part III of the volume) but instead argued in the preface how important such discoveries were to rational religion. His paper narrated the discovery chronologically, relating the long delays between experiments and his initial puzzlements; thus, it is difficult to determine when exactly Priestley "discovered" oxygen. [97] Such dating is significant as both Lavoisier and Swedish pharmacist Carl Wilhelm Scheele have strong claims to the discovery of oxygen as well, Scheele having been the first to isolate the gas (although he published after Priestley) and Lavoisier having been the first to describe it as purified "air itself entire without alteration" (that is, the first to explain oxygen without phlogiston theory). Carl Wilhelm Scheele (9 December 1742 &ndash 21 May 1786 was a German - Swedish pharmaceutical chemist born in Stralsund, Western Pomerania, [98]
In his paper "Observations on Respiration and the Use of the Blood", Priestley was the first to suggest a connection between blood and air, although he did so using phlogiston theory. The phlogiston theory (from the Ancient Greek φλογιστόν phlŏgistón "burning up" from φλόξ phlóx "fire" first stated In typical Priestley fashion, he prefaced the paper with a history of the study of respiration. A year later, clearly influenced by Priestley, Lavoisier was also discussing respiration at the Académie des sciences. The French Academy of Sciences ( French: Académie des sciences) is a Learned society, founded in 1666 by Louis XIV at the Lavoisier's work began the long train of discovery that produced papers on oxygen respiration and culminated in the overthrow of phlogiston theory and the establishment of modern chemistry. [99]
Around 1779 Priestley and Shelburne had a rupture, the precise reasons for which remain unclear. Shelburne blamed Priestley's health, while Priestley claimed Shelburne had no further use for him. Some contemporaries speculated that Priestley's outspokenness had hurt Shelburne's political career. Schofield argues that the most likely reason was Shelburne's recent marriage to Louisa Fitzpatrick—apparently, she did not like the Priestleys. Although Priestley considered moving to America, he eventually accepted Birmingham New Meeting's offer to be their minister. Birmingham ( ˈbɜːmɪŋəm Ber -ming-um [100]
In 1780 the Priestleys moved to Birmingham and spent a happy decade surrounded by old friends, until they were forced to flee in 1791 by religiously motivated mob violence. Birmingham ( ˈbɜːmɪŋəm Ber -ming-um The Priestley Riots (also known as the Birmingham Riots of 1791) took place from 14 July to 17 July 1791 in Birmingham, Priestley accepted the ministerial position at New Meeting on the condition that he be required to preach and teach only on Sundays, so that he would have time for his writing and scientific experiments. As in Leeds, Priestley established classes for the youth of his parish and by 1781, he was teaching 150 students. Because Priestley's New Meeting salary was only 100 guineas, friends and patrons donated money and goods to help continue his investigations. The guinea coin of 1663 was the first English machine-struck Gold coin. [101]
Many of the friends that Priestley made in Birmingham were members of the Lunar Society, a group of manufacturers, inventors, and natural philosophers who assembled monthly to discuss their work. The Chemical Revolution, also called the first chemical revolution, denotes the reformulation of Chemistry based on the Law of Conservation of Matter and The Lunar Society was a dinner club and informal Learned society of prominent Industrialists natural philosophers and intellectuals who met regularly between The core of the group included men such as the manufacturer Matthew Boulton, the chemist and geologist James Keir, the inventor and engineer James Watt, and the botanist, chemist, and geologist William Withering. Matthew Boulton ( September 3, 1728 &ndash 18 August 1809) was an English Manufacturer and Engineer. James Keir FRS ( 20 September 1735 &ndash 11 October 1820) Chemist, Geologist, Industrialist James Watt ( 19 January 1736 &ndash 25 August 1819 Boulton proved to be an excellent businessman and both men eventually made fortunes William Withering ( March 17, 1741, Wellington, Shropshire October 6, 1799) was an English Botanist Priestley was asked to join this unique society and contributed much to the work of its members. [102] As a result of this stimulating intellectual environment, he published several important scientific papers, including "Experiments relating to Phlogiston, and the seeming Conversion of Water into Air" (1783). The first part attempts to refute Lavoisier's challenges to his work on oxygen; the second part describes how steam is "converted" into air. After several variations of the experiment, with different substances as fuel and several different collecting apparatuses (which produced different results), he concluded that air could travel through more substances than previously surmised, a conclusion "contrary to all the known principles of hydrostatics". [103] This discovery, along with his earlier work on what would later be recognized as gaseous diffusion, would eventually lead John Dalton and Thomas Graham to formulate the kinetic theory of gases. John Dalton FRS (6 September 1766 &ndash 27 July 1844 was an English Chemist, Meteorologist and Physicist. Thomas Graham FRS ( December 21, 1805 – September 16, 1869) was born in Glasgow, Scotland. Kinetic theory (or kinetic theory of gases) attempts to explain Macroscopic properties of Gases such as pressure temperature or volume by considering [104]
In 1777, Antoine Lavoisier had published Réflexions sur le phlogistique pour servir de suite à la théorie de la combustion et de la calcination, the first of what proved to be a series of attacks on phlogiston theory; it was against these attacks that Priestley responded in 1783. Jacques-Louis David (August 30 1748 &ndash December 29 1825 was a highly influential French painter in the Neoclassical style considered to be The phlogiston theory (from the Ancient Greek φλογιστόν phlŏgistón "burning up" from φλόξ phlóx "fire" first stated While Priestley accepted parts of Lavoisier's theory, he was unprepared to assent to the major revolutions Lavoisier proposed: the overthrow of phlogiston, a chemistry conceptualized around elements and compounds, and a new chemical nomenclature. A chemical element is a type of Atom that is distinguished by its Atomic number; that is by the number of Protons in its nucleus. A chemical compound is a substance consisting of two or more different elements chemically bonded together in a fixed proportion by Mass. IUPAC Nomenclature is a system of naming Chemical compounds and of describing the science of Chemistry in general Priestley's original experiments on "dephlogisticated air" (oxygen), combustion, and water provided Lavoisier with the data he needed to construct much of his system; yet Priestley never accepted Lavoisier's new theories and continued to defend phlogiston theory for the rest of his life. Lavoisier's system was based largely on the quantitative concept that mass is neither created nor destroyed in chemical reactions (i. Mass is a fundamental concept in Physics, roughly corresponding to the Intuitive idea of how much Matter there is in an object e. , the conservation of mass). The law of conservation of mass/matter, also known as law of mass/matter conservation (or the Lomonosov - Lavoisier law says that the Mass of By contrast, Priestley preferred to observe qualitative changes in heat, colour, and particularly volume. His experiments tested "airs" for "their solubility in water, their power of supporting or extinguishing flame, whether they were respirable, how they behaved with acid and alkaline air, and with nitric oxide and inflammable air, and lastly how they were affected by the electric spark. "[105]
By 1789, when Lavoisier published his Traité élémentaire de chimie and founded the Annales de Chimie, the new chemistry had come into its own. Priestley published several more scientific papers in Birmingham, the majority attempting to refute Lavoisier. Priestley and other Lunar Society members argued that the new French system was too expensive, too difficult to test, and unnecessarily complex. Priestley in particular rejected its "establishment" aura. In the end, Lavoisier's view prevailed: his new chemistry introduced many of the principles on which modern chemistry is founded. Chemistry (from Egyptian kēme (chem meaning "earth") is the Science concerned with the composition structure and properties [106]
Priestley's refusal to accept Lavoisier's "new chemistry" — such as the conservation of mass — and his determination to adhere to a less satisfactory theory has perplexed many scholars. The law of conservation of mass/matter, also known as law of mass/matter conservation (or the Lomonosov - Lavoisier law says that the Mass of [107] Schofield explains it thus: "Priestley was never a chemist; in a modern, and even a Lavoisian, sense, he was never a scientist. He was a natural philosopher, concerned with the economy of nature and obsessed with an idea of unity, in theology and in nature. "[108] Historian of science John McEvoy largely agrees, writing that Priestley's view of nature as coextensive with God and thus infinite, which encouraged him to focus on facts over hypotheses and theories, prompted him to reject Lavoisier's system. [109] McEvoy argues that "Priestley's isolated and lonely opposition to the oxygen theory was a measure of his passionate concern for the principles of intellectual freedom, epistemic equality and critical inquiry. "[110] Priestley himself claimed in the last volume of Experiments and Observations that his most valuable works were his theological ones because they were "superior [in] dignity and importance". [111]
Although Priestley was busy defending phlogiston theory from the "new chemists", most of what he published in Birmingham was theological. In 1782 he published the fourth volume of his Institutes, An History of the Corruptions of Christianity, describing how he thought the teachings of the early Christian church had been "corrupted" or distorted. An History of the Corruptions of Christianity, published by Joseph Johnson in 1782 was the fourth part of eighteenth-century Dissenting minister Joseph [112] Schofield describes the work as "derivative, disorganized, wordy, and repetitive, detailed, exhaustive, and devastatingly argued". [113] The text addresses issues ranging from the divinity of Christ to the proper form for the Lord's Supper. Priestley followed up in 1786 with the provocatively titled book, An History of Early Opinions concerning Jesus Christ, compiled from Original Writers, proving that the Christian Church was at first Unitarian. Thomas Jefferson would later write of the profound effect that these two books had on him: "I have read his Corruptions of Christianity, and Early Opinions of Jesus, over and over again; and I rest on them … as the basis of my own faith. Thomas Jefferson (April 13 1743 – July 4 1826 was the third President of the United States (1801–1809 the principal author of the Declaration of Independence These writings have never been answered. "[114] Although a few readers such as Jefferson and other Rational Dissenters approved of the work, it was harshly reviewed because of its extreme theological positions, particularly its rejection of the Trinity. SSC RF "Troitsk Institute of Innovative and Termonuclear Research" or TRINITY for shprt Троицкий Институт инновационных и термоядерных [115]
In 1785, while Priestley was engaged in a pamphlet war over Corruptions, he also published The Importance and Extent of Free Enquiry, claiming that the Reformation had not really reformed the church. The Protestant Reformation was a reform movement in Europe that began in 1517 though its roots lie further back in time [116] In words that would boil over into a national debate, he challenged his readers to enact change:
Let us not, therefore, be discouraged, though, for the present, we should see no great number of churches professedly unitarian …. We are, as it were, laying gunpowder, grain by grain, under the old building of error and superstition, which a single spark may hereafter inflame, so as to produce an instantaneous explosion; in consequence of which that edifice, the erection of which has been the work of ages, may be overturned in a moment, and so effectually as that the same foundation can never be built upon again …. [117]
Although discouraged by friends from using such inflammatory language, Priestley refused to back down from his opinions in print and he included it, forever branding himself as "Gunpowder Joe". After the publication of this seeming call for revolution in the midst of the French Revolution, pamphleteers stepped up their attacks on Priestley and he and his church were even threatened with legal action. The French Revolution (1789–1799 was a period of political and social upheaval in the History of France, during which the French governmental structure previously an [118]
In 1787, 1789, and 1790, Dissenters again tried to repeal the Test and Corporation Acts. The Test Acts were a series of English Penal laws that served as a Religious test for public office and imposed various civil disabilities on Roman The Corporation Act of 1661 is an Act of the Parliament of England (13 Cha Although initially it looked as if they might succeed, by 1790, with the fears of revolution looming in Parliament, few were swayed by appeals to equal rights. Political cartoons, one of the most effective and popular media of the time, skewered the Dissenters and Priestley. [119] In Parliament, William Pitt and Edmund Burke argued against the repeal, a betrayal that angered Priestley and his friends, who had expected the two men's support. William Pitt the Younger (28 May 1759 &ndash 23 January 1806 was a British politician of the late eighteenth and early nineteenth centuries. Edmund Burke ( 12 January, 1729 9 July, 1797) was an Irish statesman author orator Political theorist, and Priestley wrote a series of Letters to William Pitt[120] and Letters to Burke[121] in an attempt to persuade them otherwise, but these publications only further inflamed the populace against him.
Dissenters such as Priestley who supported the French Revolution came under increasing suspicion as scepticism regarding the revolution grew. [122] In its propaganda against "radicals", Pitt's administration used the "gunpowder" statement to argue that Priestley and other Dissenters wanted to overthrow the government. Burke, in his famous Reflections on the Revolution in France (1790), tied natural philosophers, and specifically Priestley, to the French Revolution, writing that radicals who supported science in Britain "considered man in their experiments no more than they do mice in an air pump". Reflections on the Revolution in France (1790 by Edmund Burke, is one of the best-known intellectual attacks against the (then-infant French Revolution [123] Burke also associated republican principles with alchemy and insubstantial air, mocking the scientific work done by both Priestley and French chemists. Republicanism is the Ideology of governing a nation as a Republic, with an emphasis on Liberty, Rule of law, Popular sovereignty He made much in his later writings of the connections between "Gunpowder Joe", science, and Lavoisier—who was improving gunpowder for the French in their war against Britain. The French Revolutionary Wars were a series of major conflicts from 1792 until 1802 fought between the French Revolutionary government and several European states [124] Paradoxically, a secular statesman, Burke, argued against science and maintained that religion should be the basis of civil society, whereas a Dissenting minister, Priestley, argued that religion could not provide the basis for civil society and should be restricted to one's private life.

The animus that had been building against Dissenters and supporters of the American and French Revolutions exploded in July 1791. The Priestley Riots (also known as the Birmingham Riots of 1791) took place from 14 July to 17 July 1791 in Birmingham, The Priestley Riots (also known as the Birmingham Riots of 1791) took place from 14 July to 17 July 1791 in Birmingham, Priestley and several other Dissenters had arranged to have a celebratory dinner on the anniversary of the storming of the Bastille, a provocative action in a country where many disapproved of the French Revolution and feared that it might spread to Britain. The Storming of the Bastille in Paris occurred on 14 July 1789. Fearing violence, Priestley was convinced by his friends not to attend. Rioters gathered outside the hotel during the banquet and attacked the attendees as they left. They moved on to the New Meeting and Old Meeting churches—and burned both to the ground. Priestley and his wife fled from their home; although their son William and others stayed behind to protect their property, the mob overcame them and torched Priestley's house, destroying his valuable laboratory and all of the family's belongings. Other Dissenters' homes were burned in the three-day riot. Priestley spent several days hiding with friends until he was able to travel safely to London. The carefully executed attacks of the "mob" and the farcical trials of only a handful of the "leaders" convinced many at the time—and modern historians later—that the attacks were planned and condoned by local Birmingham magistrates. A magistrate is a judicial officer In Common law systems a magistrate usually has limited authority to administer and enforce the Law. When George III was eventually forced to send troops to the area, he said: "I cannot but feel better pleased that Priestley is the sufferer for the doctrines he and his party have instilled, and that the people see them in their true light. George III (George William Frederick 4 June 1738 George III's long reign was marked by a series of military conflicts involving his kingdom much of the rest of Europe and places "[126]

Unable to return to Birmingham, the Priestleys eventually settled in Clapton, near Hackney, where Priestley gave a series of lectures on history and natural philosophy at the Dissenting academy, New College. Samuel Taylor Coleridge ( 21 October 1772 &ndash 25 July 1834) was an English Poet, Critic and philosopher Hackney was a Parish in the ancient county of Middlesex. The parish church of St John-at-Hackney, was built in 1789 replacing the nearby former 16th century Friends helped the couple rebuild their lives, contributing money, books, and laboratory equipment. Priestley tried to obtain restitution from the government for the destruction of his Birmingham property, but he was never fully reimbursed. [128] He also published An Appeal to the Public on the Subject of the Riots in Birmingham (1791),[129] which indicted the people of Birmingham for allowing the riots to occur and for "violating the principles of English government". [130]
The couple's friends urged them to leave Britain and emigrate to either France or the new United States, even though Priestley had received an appointment to preach for the Gravel Pit Meeting congregation. The sermons he preached there, particularly the two Fast Sermons, reflect his growing millenarianism, his belief that the end of the world was fast approaching. Fasting is primarily the act of willingly abstaining from some or all Food, Drink, or both for a period of time This is an article on sociological Millennialism You may be looking for the article on Christian Premillennialism. After comparing Biblical prophecies to recent history, Priestley concluded that the French Revolution was a harbinger of the Second Coming of Christ. The French Revolution (1789–1799 was a period of political and social upheaval in the History of France, during which the French governmental structure previously an In Christianity, the Second Coming is the anticipated return of Jesus Christ from Heaven to earth an event that will fulfill aspects of Messianic Priestley's works had always had a millennial cast, but after the beginning of the French Revolution, this strain increased. [131] He wrote to a younger friend that while he himself would not see the Second Coming, his friend "may probably live to see it … It cannot, I think be more than twenty years [away]. "[132]
Daily life became more difficult for the family: Priestley was burned in effigy along with Thomas Paine; vicious political cartoons continued to be published about him; letters were sent to him from across the country, comparing him to the devil and Guy Fawkes; tradespeople feared the family's business; and Priestley's Royal Academy friends distanced themselves. Thomas Paine (January 29 1737 &ndash June 8 1809 was an English Pamphleteer, Revolutionary, radical, Inventor, and Intellectual Guy Fawkes ( 13 April 1570 – 31 January 1606) sometimes known as Guido Fawkes, was a member of a group of English As the penalties became harsher for those who spoke out against the government, and despite his being elected to the French National Convention by three separate departments in 1792, Priestley decided to move with his family to America. During the French Revolution, the National Convention or Convention, in France, comprised the Constitutional and legislative assembly Five weeks after Priestley left, William Pitt's administration began arresting radicals for seditious libel, resulting in the famous 1794 Treason Trials. William Pitt the Younger (28 May 1759 &ndash 23 January 1806 was a British politician of the late eighteenth and early nineteenth centuries. Seditious libel is a criminal offence under English Common law. The 1794 Treason Trials, arranged by the administration of William Pitt, were intended to cripple the British radical movement of the 1790s. [133]
The Priestleys arrived in New York City in 1794. Location Following the Seven Years' The City of New York They were immediately fêted by various political factions vying to gain Priestley's endorsement. Priestley declined their entreaties, hoping to avoid political discord in his new country. As the couple travelled to their new home in Northumberland, Pennsylvania, they stopped in Philadelphia, where Priestley gave a series of sermons and helped found the First Unitarian Church of Philadelphia. Northumberland is a borough in Northumberland County, Pennsylvania, United States. Philadelphia (ˌfɪləˈdɛlfiə The First Unitarian Church of Philadelphia is a Unitarian Universalist congregation located at 2125 Chestnut Street in Philadelphia, Pennsylvania Priestley turned down an opportunity to teach chemistry at the University of Pennsylvania, and the couple began building a home in the countryside. The University of Pennsylvania (also known as Penn) is a private University located in Philadelphia, Pennsylvania, USA. [136]
Priestley's attempts to avoid political controversy in the United States failed. In 1795, William Cobbett published Observations on the Emigration of Dr. William Cobbett ( 9 March 1763 &ndash 18 June 1835) was an English political pamphleter Farmer and prolific Joseph Priestley, which accused him of treason against Britain and attempted to undermine his scientific credibility. His political fortunes took an even worse turn when Cobbett obtained a set of letters sent to Priestley by the radical printer John Hurford Stone and the liberal novelist Helen Maria Williams, who were both living in revolutionary France. John Hurford Stone (1763 – 1818 was a British radical political reformer and publisher who spent much of his life in France Helen Maria Williams (1761 or 1762&ndash1827 was a British Novelist poet, and translator of French-language works Cobbett published the letters in his newspaper, asserting that Priestley and his friends were fomenting a revolution. [137] Priestley was eventually forced to defend himself in print. [138]
Family matters also made Priestley's time in America difficult. His son Henry died in 1795, probably of malaria. Malaria is a vector -borne Infectious disease caused by Protozoan Parasites It is widespread in tropical and subtropical regions including Mary Priestley died soon after in 1796; she was already ill and never fully recovered after the shock of her son's death. [139] After his wife's death, Priestley wrote to a friend: "I feel quite unhinged and incapable of the exertions I used to make. Having been always very domestic, reading and writing with my wife sitting near me, and often reading to her, I miss her everywhere. "[140] Priestley's family relations deteriorated even further in 1800 when a local Pennsylvania newspaper published an article accusing William Priestley, intoxicated with "French principles", of trying to poison the entire Priestley family—both father and son vigorously denied the story. [141]
Priestley continued the educational projects that had always been important to him, helping to establish the "Northumberland Academy" and donating his library to the fledging institution. He exchanged letters regarding the proper structure of a university with Thomas Jefferson, who used this advice when founding the University of Virginia. Thomas Jefferson (April 13 1743 – July 4 1826 was the third President of the United States (1801–1809 the principal author of the Declaration of Independence The University of Virginia (also called UVa, UVA, Mr Jefferson's University, or The University) is a highly selective public research Jefferson and Priestley became close and when he had completed his General History of the Christian Church,[143] he dedicated it to President Jefferson, writing that "it is now only that I can say I see nothing to fear from the hand of power, the government under which I live being for the first time truly favourable to me. "[144]
Priestley tried to continue his scientific investigations in America with the support of the American Philosophical Association. He was hampered by lack of news from Europe; unaware of the latest scientific developments, Priestley was no longer on the forefront of discovery. Although the majority of his publications focused on defending phlogiston theory, he also did some original work on spontaneous generation and dreams. The phlogiston theory (from the Ancient Greek φλογιστόν phlŏgistón "burning up" from φλόξ phlóx "fire" first stated In the Natural sciences, Abiogenesis, or origin of life, is the study of how Life on Earth emerged from Inanimate Organic Despite Priestley's reduced scientific output, his presence stimulated American interest in chemistry. [145]
By 1801, Priestley had become so ill that he could no longer write or experiment. He died on the morning of 6 February 1804.

By the time he died in 1804, Priestley had been made a member of every major scientific society in the world and he had discovered numerous substances. [149] The 19th-century French naturalist George Cuvier, in his eulogy of Priestley, praised his discoveries while at the same time lamenting his refusal to abandon phlogiston theory, calling him "the father of modern chemistry [who] never acknowledged his daughter". Baron Georges Léopold Chrétien Frédéric Dagobert Cuvier ( August 23 1769 &ndash May 13, 1832) was a French naturalist [150] Priestley published more than 150 works on topics ranging from political philosophy to education to theology to natural philosophy. [151] He led and inspired British radicals during the 1790s, paved the way for utilitarianism,[152] and helped found Unitarianism. Utilitarianism is the idea that the moral worth of an action is solely determined by its contribution to overall Utility, that is its contribution to happiness Unitarianism as a theology is the belief in the single personality of God in contrast to the doctrine of the Trinity (three persons in one God [153] A wide variety of philosophers, scientists, and poets became associationists as a result of his redaction of David Hartley's Observations on Man, including Erasmus Darwin, Coleridge, William Wordsworth, John Stuart Mill, Alexander Bain, and Herbert Spencer.

Herbert Spencer ( April 27, 1820 – December 8, 1903) was an English Philosopher; prominent classical liberal [154] Immanuel Kant praised Priestley in his Critique of Pure Reason (1781), writing that he "knew how to combine his paradoxical teaching with the interests of religion". Immanuel Kant (ɪmanuəl kant 22 April 1724 12 February 1804 was an 18th-century German Philosopher from the Prussian city of Königsberg The Critique of Pure Reason (Kritik der reinen Vernunft by Immanuel Kant, first published in 1781, second edition 1787, is one [4] Indeed, it was Priestley's aim to "put the most 'advanced' Enlightenment ideas into the service of a rationalized though heterodox Christianity, under the guidance of the basic principles of scientific method". [155]
Considering the extent of Priestley's influence, relatively little scholarship has been devoted to him. In the early 20th century, Priestley was most often described as a conservative and dogmatic scientist who was nevertheless a political and religious reformer. [156] In a historiographic review essay, historian of science Simon Schaffer describes the two dominant portraits of Priestley: the first depicts him as "a playful innocent" who stumbled across his discoveries; the second portrays him as innocent as well as "warped" for not understanding their implications better. Simon Schaffer (born 1 January 1955) was born in Brighton and was educated at Varndean Grammar School for Boys (now Varndean College) Assessing Priestley's works as a totality has been difficult for scholars because of his wide-ranging interests. His scientific discoveries have usually been divorced from his theological and metaphysical publications to make an analysis of his life and writings easier, but this approach has been challenged recently by scholars such as John McEvoy and Robert Schofield. Although early Priestley scholarship claimed that his theological and metaphysical works were "distractions" and "obstacles" to his scientific work, scholarship published in the 1960s, 1970s, and 1980s maintained that Priestley's works constituted a unified theory. However, as Schaffer explains, no convincing synthesis of his work has yet been expounded. [157] More recently, in 2001, historian of science Dan Eshet has argued that efforts to create a "synoptic view" have resulted only in a rationalization of the contradictions in Priestley's thought, because they have been "organized around philosophical categories" and have "separate[d] the producers of scientific ideas from any social conflict". [158]
Priestley has been remembered by the towns in which he served as a reforming educator and minister and by the scientific organizations he influenced. Two educational institutions have been named in his honour: Priestley College in Warrington and Joseph Priestley College in Leeds. Priestley Sixth Form and Community College is a Sixth form college for 16-19 year olds located on Loushers Lane Warrington, England. Joseph Priestley College is a Further education college founded in 1955 serving the communities of South Leeds. This article discusses the metropolitan district of the City of Leeds. [159] In Birstall, the Leeds City Square, and Birmingham, he is memorialized through statues,[160] and plaques commemorating him have been posted in Birmingham and Warrington. City Square is a paved open area in Leeds city centre in West Yorkshire, England. Chamberlain Square or Chamberlain Place is a public square in central Birmingham, England ( named after Joseph Chamberlain. [161] Also, since 1952 Dickinson College has presented the Priestley Award to a scientist who makes "discoveries which contribute to the welfare of mankind". Dickinson College is a private residential liberal arts college in Carlisle Pennsylvania. [162]

The most exhaustive biography of Priestley is Robert Schofield's recent two-volume work; several one-volume treatments exist, all somewhat older: Gibbs, Holt and Thorpe. Graham and Smith focus on Priestley's life in America and Uglow and Jackson both discuss Priestley's life in the context of other developments in science.
