Dudgeon, William, was a Scottish freethinker and philosopher. A tenant farmer who resided at Lennel Hill Farm, near Coldstream, Berwickshire, he was one of several philosophers active in the borders area of Scotland during this period. Other figures in this group include Andrew Baxter, Henry Home, and most importantly David Hume. Dudgeon's first work was 'The Necessity of some of the Positive Institutes of Ch__ty Considered'. This work was a defence of Matthew Tindal's doctrines in 'Christianity as Old as Creation', which had been criticized by Robert Wallace. Dudgeon's next and most controversial work was 'The State of the Moral World Considered'. In this work he defended a metaphysical optimism that is similar to that of Anthony Ashley-Cooper, 3rd Earl of Shaftesbury, as well as a necessitarian doctrine not unlike that of Anthony Collins. This work drew a hostile reply from Andrew Baxter, who was Scotland's most prominent defender of the philosophy of Samuel Clarke. Baxter accused Dudgeon of both ‘atheism’ and ‘scepticism’. These charges encouraged the local clergy in the presbytery of Chirnside to prosecute Dudgeon on the ground that he was the author of a work that ‘contains many gross errors subversive of Christianity’. One of the clerics involved was an uncle of David Hume. Among Dudgeon's other major works is 'Philosophical Letters', written to John Jackson, another prominent defender of Clarke's philosophy. In this work Dudgeon criticized Clarke's Newtonian metaphysics and morals. By way of alternative he defended a form of pantheistic immaterialism that blended the views of George Berkeley and Spinoza, along with a moral sense ethics in line with Shaftesbury. This work was favourably reviewed in the journal 'History of the Works of the Learned', where Dudgeon's ‘Spinozism’ was noted. In another controversy Dudgeon tangled with William Warburton on the subject of Pope's 'Essay on Man'. Warburton, a friend of Baxter's, referred to Dudgeon as belonging to ‘the tribe of Free-thinkers’ and placed him in the same company as John Toland, Matthew Tindal, and Anthony Collins. Some years later John Witherspoon, in his satirical work 'Ecclesiastical Characteristics', mentioned Dudgeon along with a number of thinkers, including Shaftesbury, Gottfried Wilhelm Leibniz, Collins, and Kames, whose ideas had been influential on the ‘moderate’ party in the Church of Scotland. These controversies and references suggest that Dudgeon's philosophy enjoyed some influence on both sides of the border. There is no evidence that Dudgeon and Hume had any direct contact. Nevertheless, given their close proximity when Hume was young and philosophically active, and the role of Hume's uncle in Dudgeon's prosecution, it is reasonable to assume that Hume knew of Dudgeon's philosophical work and the associated controversies involving Baxter and Warburton. Suffice it to note that Dudgeon and Hume shared philosophical interests and that on a number of significant issues they took up similar positions. Dudgeon, a resolute defender of the thesis that all is for the best, died of consumption, aged thirty-seven, on 28 January 1743 at Upsettlington, Berwickshire. His most important works were gathered into a single volume, which was published without a printer's name attached in 1765.
