Even apart from deism there had arisen a widespread aversion to dogmatic theology and formal creeds, so that an apologist of 1715 speaks of his day as "a time when creeds and Confessions of Faith are so generally decried, and not only exposed to contempt, as useless inventions ... but are loaded by many writers of distinguished wit and learning with the most fatal and dangerous consequences." [824] This writer admits the intense bitterness of the theological disputes of the time; [825] and he speaks, on the other hand, of seeing "the most sacred mysteries of godliness impudently denied and impugned" by some, while the "distinguishing doctrines of Christianity are by others treacherously undermined, subtilized into an airy phantom, or at least doubted, if not disclaimed." [826] His references are probably to works published in England, notably those of Locke, Toland, Shaftesbury, and Collins, since in Scotland no such literature could then be published; but he doubtless has an eye to Scottish opinion. While, however, the rationalism of the time could not take book form, there are clear traces of its existence among educated men, even apart from the general complaints of the apologists. Thus the Professor of Medicine at Glasgow University in the opening years of the eighteenth century, John Johnston, was a known freethinker. [827] In the way of moderate or Christian rationalism, the teaching of the prosecuted Simson seems to have counted for something, seeing that Francis Hutcheson at least imbibed from him "liberal" views about future punishment and the salvation of the heathen, which gave much offence in the Presbyterian pulpit in Ulster. [828] And Hutcheson's later vindication of the ethical system of Shaftesbury in his Inquiry Concerning the Ideas of Beauty and Virtue (1725) must have tended to attract attention in Scotland to the Characteristics after his instalment as a Professor at Glasgow. In an English pamphlet, in 1732, he was satirized as introducing Shaftesbury's system into a University, [829] and it was from the Shaftesbury camp that the first literary expression of freethought in Scotland was sent forth. A young Scotch deist of that school, William Dudgeon, published in 1732 a dialogue entitled The State of the Moral World Considered, wherein the optimistic position was taken up with uncommon explicitness; and in 1739 the same writer printed A Catechism Founded upon Experience and Reason, prefaced by an Introductory Letter on Natural Religion, which takes a distinctly anti-clerical attitude. The Catechism answers to its title, save insofar as it is à priori in its theism and optimistic in its ethic, as is another work of its author in the same year, A View of the Necessarian or Best Scheme, defending the Shaftesburyan doctrine against the criticism of Crousaz on Pope's Essay. Still more heterodox is his little volume of Philosophical Letters Concerning the Being and Attributes of God (1737), where the doctrine goes far
