1. Popular poem, cited in an editorial footnote to Priestley's An appeal to the public on the subject of the riots in Birmingham (1791), in John Towill Rutt (ed.), The theological and miscellaneous works of Joseph Priestley (London, 1817-32;
2. hereafter cited as Works), xix, 356-57, n †. The poem reflects the popular beliefs that Priestley secreted gunpowder under a church so as to blow it up during a sermon, and that barrels of gunpowder were actually found in his laboratory during the "Priestley Riots". The accusation echoed the events surrounding the Gunpowder Plot of 1605.

The suppression of these and other popular organizations began right around the time Priestley was preparing to leave England; the British authorities had decided that the disturbances inspired by the French Revolution as well as by the reform movement in England had gotten out of hand.

The letters that Rutt published in Priestley's autobiography do not give a full sense of his connections with the leaders of the opposition to the British government. Similarly, his biography plays down this part of his life. But other sources confirm that he regularly dined with and met such figures as Benjamin Franklin, Josiah Quincy, John Adams and many other American rebels and leaders when they came to visit England. Similarly he was in contact with Richard Price, Theophilus Lindsey, John Jebb, Michael Dodson and many others who were active in British politics.
13. Theophilus Lindsey, Letters of Theophilus Lindsey, ed. by Herbert McLachlan (Manchester, 1920) is anecdotal but provides a sharply defined picture of the activities of Priestley and his radical friends during the 1770s, 1780s and 1790s (see esp. chs 3-5).

(Probably Lavoisier's most vocal partisan in Scotland was Joseph Black (1728-99).) It should be mentioned that Priestley had a running debate with the Scottish Common Sense school; the school's warm reception of Lavoisier's new chemistry did not predispose Priestley to give it a fair hearing.

46. A close examination of this issue can make even Thomas Kuhn look like a Whiggish historian, for his emphasis on the incommensurability of phlogiston and oxygen makes him look like an advocate of the idea of progressive revolutions in science (see Thomas S. Kuhn, The structure of scientific revolutions, 2nd edn (Chicago, 1970), 52-56).
47. This aspect of Kuhn's thinking was elaborated in H. Gilman McCann, Chemistry transformed: The paradigmatic shift from phlogiston to oxygen (New Jersey, 1978).

49. While McCann, in his Chemistry transformed (ref. 17), deals with such sociological issues as academic communities in Edinburgh, London and Paris, he also looks (in ch. 3) at the internal development of scientific theories to argue that theoretical anomalies and inadequacies brought about the Chemical Revolution. In another important study of eighteenth-century materialism.
50. Aram Vartanian argues that "the sources and meanings alike of scientific naturalism in the eighteenth century are ... most intimately, although by no means exclusively, discoverable in the complex of Cartesian thought" (Aram Vartanian, Diderot and Descartes: A study of scientific naturalism in the Enlightenment (Princeton, 1953), 292).
51. Roger Joseph Boscovich (1711-87) was a Jesuit whose work Priestley probably discovered over the course of his reading for History and present state of discoveries relating to vision, light and colours (London, 1772; hereafter cited as History of optics). A mathematician, an astronomer and the author of Theoria naturalis philosophiae (1758; English translation 1763), Boscovich is considered the modernizer of atomic theory. He never subscribed to Priestley's materialism. Boscovich revised Newton's corpuscular theory of matter and essentially saw the world as made up of tiny billiard balls. He reduced the attributes of matter (impenetrability, solidity, extension) to forces, which permitted a better accounting for an array of phenomena. Boscovich's atom had no extension and could not be considered matter, since it was strictly the centre point of force. See Leslie P. Williams, Michael Faraday: A biography (New York, 1965), 73-80;

59. Schaffer, A scientific autobiography of Joseph Priestley, 1733-1804: Selected scientific correspondence op. cit. (ref. 6), 23. The second part of Schofield's biography of Priestley has not yet been published. Priestley read British mechanistic theories of attraction and repulsion some twenty-five years before he came across the work of Boscovich.
60. Schofield suggests that there was little in Boscovich's theory that Priestley did not know and that he owed his scientific ideas to the physicalist tradition in which he had been trained (Schofield, A scientific autobiography of Joseph Priestley, 1733-1804: Selected scientific correspondence op. cit. (ref. 11, 1967), 9-10).
61. "In view of the obvious inadequacies in the orthodox view of Priestley's scientific thought, [my] study will provide a new historiography for Priestley scholarship that seeks to replace the appearance of a wayward, and somewhat schizoid mentality, by the reality of Priestley's considerable synoptic powers.... The categories of Priestley's thought reveals a mind with unusual synoptic power, bent on the articulation of the interconnections and ramifications of the central doctrines of his philosophy of nature."

71. As Golinski and others have pointed out, Priestley was in touch with other scientists and joined the Lunar Society after the 1780s. I am not convinced that these connections influenced his science to the extent that the Dissenters did.
72. Priestley has provided his own explanation of the long incubation of Hartley's ideas in the preface to Joseph Priestley, Disquisitions relating to matter and spirit ... (London, 1777).

79. I use the term 'epistemology' to designate what Priestley thought of as the foundation of human knowledge. In other words, this was what humans could expect to know and what they could not, given their constitution. An "egalitarian epistemology" is one that posits the equal capacity of all humans for understanding some things even if they are incapable of knowing others. The best formulation of this position is in Joseph Priestley, Institutes of natural and revealed religion ... (London, 1772); this was Priestley's first major publication.

84. Haggerstone's curriculum was largely devoted to mathematics. Priestley thought that this Baxterian minister was "a little more liberal than the members of the congregation in which [he] was brought up" and found that conversation with his teacher "tended to undermine [his own Calvinist] prejudices" (Priestley, op. cit. (ref. 9), Works, i, Part 1, 14-15).
85. Andrew Baxter (1686(?)-1750), was a theological and philosophical writer. Baxterians occupied a position somewhere between the Calvinists, who believed that grace was entirely predetermined by God, and the Arminians, who believed in salvation through works and faith. Arianism, named for its founder Arius, was a more radical movement that denied the tenets of Calvinism. Most Britons saw Arians as heretics since they denied the divinity and eternity of Christ. But definitions varied a lot and Priestley, who converted to Arianism himself, never denied Christ's divinity. Priestley's brother Timothy, who adopted Evangelicalism with a zeal not unlike Priestley's, delivered a eulogy at Priestley's death. In it he suggested that Priestley, who had met Haggerstone again in 1774, had said to Timothy that his mathematics teacher was the "man who brought [him] out of the dark hole of Calvinism" (Timothy Priestley, A funeral sermon occasioned by the death of ... Rev. Joseph Priestley (London, 1804), 40-41;
86. see also R. V. Taylor, Yorkshire anecdotes (London, 1887), 239-40).
87. Priestley, op. cit. (ref. 9), Works, i, Part 1, 11.
88. According to Priestley, Walker was an excellent classical scholar and a Rational Christian. He was an Arminian and possibly subscribed to Arian beliefs, rejecting, among other things, the Calvinist notion of predestination and embracing the principle that free will played a part in the attainment of grace. Most likely Walker was one of the Socian or Arian ministers Timothy Priestley accused of having lured his brother away from Haggerstone's Baxterianism (T. Priestley, Works, op. cit. (ref. 37), 37). Socianism (named after Socianus) was an early form of Unitarianism and denied the Trinity.
89. William Graham objected to the doctrine of atonement (this would be a favourite target of Priestley's later on) as well as to the Trinity. Priestley saw in him a true Unitarian. He taught Priestley classical literature and made a lifelong impression on a young man who was then rather orthodox in his Christian beliefs.
90. Schofield has rightly suggested that the trauma of being turned out of his childhood chapel for heresy marked Priestley's early drift from mainstream Calvinism (Schofield, Works op. cit. (ref. 12, 1997), 1-3, 32-35).
91. Priestley, op. cit. (ref. 9), Works, i, Part 1, 15, 18. Arianism is the doctrine that denies the true divinity of Christ. Arius (born in Egypt c. 250, died in Constantinople in 336), who articulated the basic Arian philosophy in a poetical work entitled Thalia, maintained that the Son of God had not been endowed with eternal life and was created by the Father from nothing -he was not himself godly. Arians, who first appeared in England in the middle of the seventeenth century, rejected the doctrine of the Trinity along with the divinity of Christ. Was Priestley a heretic? Definitions are tricky and it is not clear that at this point in Priestley's life he denied the divinity of Christ altogether. But in the eyes of most Britons, Arianism was a principal heresy (since it involved the denial of the divinity or eternity of Christ) and association with Arians could very well have earned Priestley this reputation.
92. Between 1752 and 1755 Priestley received the equivalent of a university education at Daventry. Between 1761 and 1767 he worked and taught at Warrington. Finally, after his house was burned in 1791 and up until the time of his departure for America in 1794, Priestley taught at Hackney New College, which replaced Warrington when that school shut its doors.
93. P. O'Brien, Warrington Academy, 1757-1786: Its predecessors and successors (Wigan, 1989), 9-11. The laws aimed against the Nonconformists were repressive. First, the Corporation Act of 1661 required members of the government and of borough corporations to take a political oath of allegiance to the Crown and to perform the Anglican sacraments. As is well known, within two years of the Restoration those who refused were ejected from the Church. Some two thousand English and Welsh clergymen lost their positions, along with their livings. Second, the new leaders in Parliament were determined to eradicate Nonconformity root and branch. They passed the Act of Uniformity in 1662, which required all those in ecclesiastical positions to subscribe to the religious oaths earlier imposed on members of corporations, and to declare their full acceptance of the Anglican Book of common prayer (1549, final revision 1662). While this Act did not produce uniformity, it did stop Dissenters from playing an active role in their communities. And though the Conventicle Act that followed (1664) implied the acceptance of private worship by Dissenters, it created yet another obstacle to the normal operation of sectarian congregations by outlawing private religious meetings of more than five persons. Fourth, the Five Miles Act (1665) forbade ministers and preachers who had lost their licenses from coming within five miles of the parish in which they had held office, and they were barred from entering any town or corporate borough. Finally, and most importantly, the Test Act (1673, 1678) obliged office holders (civil and religious alike) to take a doctrinal oath (in addition to the political oath of loyalty to the state already required).
94. These oaths were to be taken in open court and written proof that the office holders had recently taken communion in the Established Church was required (John P. Kenyon, The Stuart constitution, 1603-1688: Documents and commentary (London, 1976), 337, 339, 351-2, 356, 376-9, 385-6;

108. For an attempt to discuss the institutional context, see Golinski, Lives of eminent Unitarians op. cit. (ref. 25), 16-25. I am not convinced that this article's focus on scientific communities (as opposed to the religious communities that I am focusing on) can actually be justified. The only real community of this sort was the Lunar Society, which Priestley joined after he moved to Birmingham, in the 1780s. By then his positions on all the major issues were quite settled. A focus on scientific communities projects the idea of an autonomous scientific practice anachronistically onto the eighteenth century - such autonomy is hard to reconcile with Priestley's work.

112. On Doddridge, see John Stoughton, Philip Doddridge: His life and labours; a centenary memorial (London, 1851), 89-91. The attack on Doddridge followed his conviction by "the Spiritual Court" of presiding over and teaching at a Northampton seminary. He died just as the Daventry Academy first opened its doors and was succeeded by Caleb Ashworth (1722-75).
113. A detailed review of Priestley's education at Daventry is provided in Schofield, Philip Doddridge: His life and labours; a centenary memorial op. cit. (ref. 12), 40-62. Information on Hartley is provided below. Doddridge served as a tutor to many prominent figures in the Dissenting community. Some of these figures later became close associates and friends of Priestley. An example is the Rev. John Aikin, whose family Priestley befriended at the Warrington Academy.

Effectively a Dissenter, Hartley became a physician and philosopher and developed a psychological system known as "associationism" upon which Priestley was to draw extensively.
118. "Necessarianism" should not be confused with Calvinism or predestination. It refers to a causal, material connection between all natural phenomena.

With the closing of the private academies set up at Kendal and Findern (1754), Nonconformist students desperately needed a new academy; Seddon responded to that need. John Seddon had a Unitarian cousin by the same name, with whom he is sometimes confused.
122. Thorpe, Works op. cit. (ref. 11), 34.
123. Upon completing his studies in Glasgow, Seddon opened the new academy in 1757 (O'Brien, Works op. cit. (ref. 43), 45;
124. Smith, Works op. cit. (ref. 48), 160-7).
125. Students at the Warrington Academy also studied the three classical arts of law, medicine and divinity. Margaret C. Jacob recently illustrated the contribution of several Dissenters to the industrial culture of the eighteenth century. See her "Commerce, industry, and the laws of Newtonian science", Canadian journal of history, xxxv (2000), 275-92.
126. For a survey of student interest in the various fields of concentration, see Parker, Dissenting academies in England (ref. 49), appendix 5.
127. On the academy's curriculum, see Smith, Dissenting academies in England op. cit. (ref. 48), 166-9. The Warrington Academy was one of the first to employ more than one tutor. Furthermore, it enjoyed an institutional identity quite distinct from the Nonconformist congregation of Warrington. The academy was also one of the first at which the natural sciences were studied, as well as the first to become Arian and eventually Unitarian.

Among Priestley's colleagues and friends at Warrington were Dr John Taylor (who taught divinity), Dr John Aikin the elder (theology, ethics and logic), Dr John Reinhold Forster (a naturalist and traveller who accompanied Cook on one of his voyages) and Dr William Enfield (mathematics and natural sciences).
130. Another tutor with whom Priestley had extensive exchanges was the eccentric Dissenter and classicist Gilbert Wakefield, but he joined the academy after Priestley had left (Thorpe, Enlightenment and dissent, op. cit. (ref. 11), 33-34;
131. Smith, Enlightenment and dissent, op. cit. (ref. 48), 161-8). Warrington was also home to Anna Laetitia Barbauld (daughter of John Aikin Sr, a famous poet and publicist), her brother John Aikin Jr (a promoter of medical reforms at the turn of the century) and many more whose contributions to the formation of Dissenting ideology were invaluable.

141. In the preface to the second edition of his Essay on the first principles of government (1771), Works, xxii (hereafter cited as Essay (1771)), Priestley himself modestly stated that he had placed the most valuable interests of mankind on a broader foundation and a firmer basis than had Locke and others who had formerly written upon this subject (p. 3). Locke had refused to reject anyone who was Protestant. Priestley went further, arguing for a complete and limitless toleration, which included Catholics, unbelievers and other religious minorities (p. 63; see also p. 72, n. *).
142. Priestley supported the universal language of toleration of any opinion of any man: "Ask for the common right of humanity" in matters of beliefs, he advised his fellow Dissenters in his A letter of advice to those Dissenters who conduct the application to Parliament for relief from certain penal laws (1773) (Works, xxii, 442-43 [my italics]).
143. See the plea for tolerating Catholics in Joseph Priestley, A free address to those who have petitioned for the repeal of the late Act of Parliament, in favour of the Roman Catholics (1780), Works, xxii, 499-516. Unfortunately, this position brought down on him the wrath not only of the clergy but also of his fellow Dissenters.
144. Priestley, op. cit. (ref. 9), Works, i, Part 1, 68-70.
145. A work that made up Priestley's mind for good was A letter to Lord Viscount Barrington: (written in the year 1730) concerning the question, whether the logos supplied the place of a human soul in the person of Jesus Christ (London, 1833), written by Nathaniel Lardner (1684-1768). Following Lardner, Priestley believed that Christ was chosen by God to carry out his word: this was reason enough to love and adore him, but Christ was not invested with the powers of the Divine. See Rutt's n. * in Priestley, op. cit. (ref. 9), Works, i, Part 1, 69-71.

159. Contrary to the argument made in Linda Colley, Britons: Forging the nation, 1707-1837 (New Haven, 1992), ch. 3, I doubt that Wilkes was accepted as a true patriot by the British; many radicals claimed that their motives were patriotic (Richard Price and Priestley among them), but few were convinced by this.
160. See Lincoln, Britons: Forging the nation, 1707-1837 op. cit. (ref. 65), 22-29.
161. Priestley remarked that he had written several "anonymous pieces in favour of civil liberties, during the persecution of Mr. Wilkes" (Priestley, op. cit. (ref. 9), Works, i, Part 1, 75).
162. One of these, written at the suggestion of his editor, was The present state of liberties in Great Britain and her colonies ... (1769). There Priestley argued that the "great Bill of Rights has been invaded by a repeated refusal, to admit the first county in England, to judge of the fitness of the person who shall represent them in parliament; and one whom they had freely chosen has been excluded, though guilty of no crime" (idem. The present state of liberties in Great Britain and her colonies ..., Works, xxii, 390).
163. Sec also Graham, Works, op. cit. (ref. 60), Part 1, 55-56.
164. After the riots of 1791, Priestley suggested that he had written very few other political pamphlets (Graham, idem, Works, op. cit. (ref. 3), 425). His opponents insisted on a connection between his early views, his radical theological views and his support of both the American and French Revolutions.

What that means in this case is that he strongly advocated the right of oppressed peoples to rebel against tyrannical government (Graham, City and society in the eighteenth century ibid., 7-9).

178. Warburton was chaplain to the King and, later, Bishop of Gloucester. The title of his treatise, somewhat abbreviated, was The alliance between Church and State; or the necessity and equity of an established religion and a test-law demonstrated: From the essence and end of civil society (London, 1736). Warburton advocated the toleration of Nonconformists but opposed the repeal of the Test and Corporation Acts, a favourite target of the Dissenters. Given the form of Warburton's essay, it is not surprising that Priestley chose to write a defence of religious toleration in the form of a work on the nature of civil society.
179. See Barlow, The alliance between Church and State; or the necessity and equity of an established religion and a test-law demonstrated: From the essence and end of civil society op. cit. (ref. 66), 52-56.
180. Balguy (at that time archdeacon of Winchester) published his Letter concerning confessions of faith, and subscriptions to articles of religion in Protestant churches; occasioned by perusal of the confessional (by Francis Blackburne) (London, 1768), to which Priestley responded in his 1769 Considerations on Church authority (included in the second edition of the Essay). Priestley argued that an individual's commitments to God were far more important than his commitments to the state.

184. We should note that the subtitle to Essay runs as follows: An essay on the first principles of government; and on the nature of political, civil, and religions liberty. In my discussion of this issue in the second part of this section I will rely on the second edition.

192. In a later (and angrier) pamphlet, Priestley reiterated that "the most important questions relating to religion are the plainest things in the world, and require nothing but a common understanding, honestly applied, to comprehend them" (Priestley, Essay (op. cit. (ref. 2), 191).

204. For an excellent discussion of the term 'republicanism', see Fruchtman, Essay (op. cit. (ref. 6), chs 2-3).
205. Pocock's interpretation of republicanism, which assigns the landed élite and its property the central role in government, is incompatible with Priestley's idea of civil society (J. G. A. Pocock, The Machiavellian moment: Florentine political thought and the Atlantic republican tradition (Princeton, 1975);

Priestley's model placed the "majority of those whose circumstances render them above being corrupt" at the centre (with no reference to property of any kind); while he preferred indirect elections, his political model is as democratic as it gets in the eighteenth century.
209. The British system struck him as "very unequal and imperfect" (Joseph Priestley, Virtue, commerce, and history: Essays on political thought and history, chiefly in the eighteenth century op. cit. (ref. 70, 1769), 385, 394).

222. John Michell (1724-93), an astronomer and member of the Royal Society (which he joined in 1760), helped Priestley in the preparation of his study of optics as well as in working out his ideas about materialism (Schofield, Experiments and observations on different kinds of air, 3rd edn op. cit. (ref. 20), 244-6).

225. See also Yolton, The development of Newtonian optics in England op. cit. (ref. 18), 110-11. Boscovich's "particles" were the centre-point of forces but had no existence in themselves. Priestley's theory was indeed Newtonian or corpuscular, but he differed from Anglican Newtonians in that he thought of forces as an integral part of matter.
226. Priestley, History of optics (ref. 19), 391.
227. Priestley, History of optics Ibid., 390-1. As I mentioned earlier, Priestley took his cue from Boscovich, who argued that matter consisted of "physical points" imbued with or surrounded by forces of attraction and repulsion. But for Priestley the materialist, those "points" meant something entirely different for he saw in them the most fundamental form of matter.
228. On the prevalence of Newtonian optics in the mid-eighteenth century, see Steffens, History of optics op. cit. (ref. 97), 51-66.
229. A defining moment in early eighteenth-century Newtonianism was the correspondence between Samuel Clarke (1675-1729), Newton's loyal disciple, and the German philosopher and mathematician, Gottfried Wilhelm Leibnitz (1646-1716). Over the course of their dialogue, Clarke elaborated the position I have described as that of "Anglican Newtonians". See Samuel Clarke, A collection of papers, which passed between the late learned Mr. Leibnitz, and Dr. Clarke ... (London, 1717).

240. Joseph Priestley, Idem, First introductory essay, Hartley's Theory of the human mind, on the principle of the association of ideas; with essays relating to the subject of it by Joseph Priestley (London, 1775), p. vii. Priestley argued that Hartley (1705-57) had drawn his principles from Newton, who was the first to suggest a theory of vibrations. At the end of his Principia and in the Queries at the end of his Opticks (e.g., Query 13), Newton wondered if the process by which ideas of external objects were created might involve the mechanical transmission of sensations. He suggested that beams of light excited the retina by vibrations, which were then transmitted through the optic nerve to the brain to create an impression.
241. But Priestley relied heavily on Locke, one of the few who thought, according to Priestley, "that a capacity of thinking may be given to matter" (Joseph Priestley, Hartley's Theory of the human mind, on the principle of the association of ideas; with essays relating to the subject of it by Joseph Priestley Ibid., p. xix).

249. Lord Shelburne supported a number of radicals, including Wilkes, Price, Priestley and Bentham (see Schaffer, Hartley's Theory of the human mind, on the principle of the association of ideas; with essays relating to the subject of it by Joseph Priestley op. cit. (ref. 103), 238, 252-8). Shelburne was educated at Oxford, served in the Seven Years' War and first entered Parliament in 1760. He was prime minister between 1772 and 1783, but had to resign because of the objections of the Foxite Whigs (despite his opposition to the war). He did not serve in any official capacity after 1783. But Shelburne supported the Dissenters on several occasions, especially when they revived their appeal for the repeal of the Test Act in 1772. Such sympathies made it possible for Shelburne to hire Priestley and then to employ him in a variety of tasks, including the tutelage of his children.
