In the case of Adam Smith we have one of the leading instances of the divorce between culture and creed in the Scotland of that age. His intellectual tendencies, primed by Hutcheson, were already revealing themselves when, seeking for something worth study in the unstudious Oxford of his day, he was found by some suspicious supervisor reading Hume’s Treatise of Human Nature. The book was seized and the student scolded.[162] When, in 1751, he became Professor of Moral Philosophy in Glasgow University, he aroused orthodox comment by abandoning the Sunday class on Christian Evidences set up by Hutcheson, and still further, it is said, by petitioning the Senatus to be allowed to be relieved of the duty of opening his class with prayer.[163] The permission was not given; and the compulsory prayers were “thought to savour strongly of natural religion”; while the lectures on Natural Theology, which were part of the work of the chair, were said to lead “presumptuous striplings” to hold that “the great truths of theology, together with the duties which man owes to God and his neighbours, may be discovered by the light of nature without any special revelation.”[164] Smith was thus well founded in rationalism before he became personally acquainted with Voltaire and the other French freethinkers; and the pious contemporary who deplores his associations avows that neither before nor after his French tour was his religious creed ever “properly ascertained.”[165] It is clear, however, that it steadily developed in a rationalistic direction. In the Theory of Moral Sentiments (1759) the prevailing vein of theistic optimism is sufficiently uncritical; but even there there emerges an apparent doubt on the doctrine of a future state, and positive hostility to certain ecclesiastical forms of it.[166] In the sixth edition, which he prepared for the press in 1790, he deleted the passage which pronounced the doctrine of the Atonement to be in harmony with natural ethics.[167] But most noteworthy of all is his handling of the question of religious establishments in the Wealth of Nations.[168] It is so completely naturalistic that only the habit of taking the Christian religion for granted could make men miss seeing that its account of the conditions of the rise of new cults applied to that in its origin no less than to the rise of any of its sects. As a whole, the argument might form part of Gibbon’s fifteenth chapter. And even allowing for the slowness of the average believer to see the application of a general sociological law to his own system, there must be inferred a great change in the intellectual climate of Scottish life before we can account for Smith’s general popularity at home as well as abroad after his handling of “enthusiasm and superstition” in the Wealth of Nations. The fact stands out that the two most eminent thinkers in Scotland in the latter half of the eighteenth century were non-Christians,[169] and that their most intellectual associates were in general sympathy with them.
§ 11
In Ireland, at least in Dublin, during the earlier part of the century, there occurred, on a smaller scale, a similar movement of rationalism, also largely associated with Shaftesbury. In Dublin towards the close of the seventeenth century we have seen Molyneux, the friend and correspondent of Locke, interested in “freethought,” albeit much scared by the imprudence of Toland. At the same period there germinated a growth of Unitarianism, which was even more fiercely persecuted than that of Toland’s deism. The Rev. Thomas Emlyn, an Englishman, co-pastor of the Protestant Dissenting Congregation of Wood Street (now Strand Street), Dublin, was found by a Presbyterian and a Baptist to be heretical on the subject of the Trinity, and was indicted in 1702 for blasphemy. He was sentenced to two years’ imprisonment and a fine of £1,000, which was partly commuted on his release. He protested that South and Sherlock and other writers on the Trinitarian controversy might have been as justly prosecuted as he; but Irish Protestant orthodoxy was of a keener scent than English, and Emlyn was fain, when released, to return to his native land.[170] His colleague Boyse, like many other Churchmen, wished that the unhappy trinitarian controversy “were buried in silence,” but was careful to conform doctrinally. More advanced thinkers had double reason to be reticent. As usual, however, persecution provoked the growth it sought to stifle; and after the passing of the Irish Toleration Act of 1719, a more liberal measure than the English, there developed in Ulster, and even in Dublin, a Unitarian movement akin to that proceeding in England.[171] In the next generation we find in the same city a coterie of Shaftesburyans, centring around Lord Molesworth, the friend of Hutcheson, a man of affairs devoted to intellectual interests. It was within a few years of his meeting Molesworth that Hutcheson produced his Inquiry, championing Shaftesbury’s ideas;[172] and other literary men were similarly influenced. It is even suggested that Hutcheson’s clerical friend Synge, whom we have seen[173] in 1713 attempting a ratiocinative answer to the unbelief he declared to be abundant around him, was not only influenced by Shaftesbury through Molesworth, but latterly “avoided publication lest his opinions should prejudice his career in the Church.”[174] After the death of Molesworth, in 1725, the movement he set up seems to have languished;[175] but, as we have seen, there were among the Irish bishops men given to philosophic controversy, and the influence of Berkeley cannot have been wholly obscurantist. When in 1756 we read of the Arian Bishop Clayton[176] proposing in the Irish House of Lords to drop the Nicene and Athanasian creeds, we realize that in Ireland thought was far from stagnant. The heretic bishop, however, died (February, 1758) just as he was about to be prosecuted for the anti-Athanasian heresies of his last book; and thenceforth Ireland plays no noticeable part in the development of rationalism, political interests soon taking the place of religious, with the result that orthodoxy recovered ground.
It cannot be doubted that the spectacle of religious wickedness presented by the operation of the odious penal laws against Catholics, and the temper of the Protestant Ascendancy party in religious matters, had bred rational skepticism in Ireland in the usual way. Molesworth stands out in Irish history as a founder of a new and saner patriotism; and his doctrines would specially appeal to men of a secular and critical way of thinking. Heretical bishops imply heretical laymen. But the environment was unpropitious to dispassionate thinking. The very relaxation of the Penal Code favoured a reversion to “moderate” orthodoxy; and the new political strifes of the last quarter of the century, destined as they were to be reopened in the next, determined the course of Irish culture in another way.
§ 12
In England, meanwhile, there was beginning the redistribution of energies which can be seen to have prepared for the intellectual and political reaction of the end of the century. There had been no such victory of faith as is supposed to have been wrought by the forensic theorem of Butler. An orthodox German observer, making a close inquest about 1750, cites the British Magazine as stating in 1749 that half the educated people were then deists; and he, after full inquiry, agrees.[177] In the same year, Richardson speaks tragically in the Postscriptum to Clarissa of seeing “skepticism and infidelity openly avowed, and even endeavoured to be propagated from the press; the great doctrines of the gospel brought into question”; and he describes himself as “seeking to steal in with a disguised plea for religion.” Instead of being destroyed by the clerical defence, the deistic movement had really penetrated the Church, which was become as rationalistic in its methods as its function would permit, and the educated classes, which had arrived at a state of compromise. Pope, the chief poet of the preceding generation, had been visibly deistic in his thinking; as Dryden had inferribly been before him; and to such literary prestige was added the prestige of scholarship. The academic Conyers Middleton, whose Letter from Rome had told so heavily against Christianity in exposing the pagan derivations of much of Catholicism, and who had further damaged the doctrine of inspiration in his anonymous Letter to Dr. Waterland (1731), while professing to refute Tindal, had carried to yet further lengths his service to the critical spirit. In his famous Free Inquiry into the miracles of post-apostolic Christianity (1749), again professing to strike at Rome, he had laid the foundations of a new structure of comparative criticism, and had given permanent grounds for rejecting the miracles of the sacred books.
Middleton’s book appeared a year after Hume’s essay Of Miracles, and it made out no such philosophic case as Hume’s against the concept of miracle; but it created at once, by its literary brilliance and its cogent argument, a sensation such as had thus far been made neither by Hume’s philosophic argument nor by Francklin’s anticipation of that.[178] Middleton had duly safeguarded himself by positing the certainty of the gospel miracles and of those wrought by the Apostles, on the old principle[179] that prodigies were divinely arranged so far forth as was necessary to establish Christianity, but no further. “The history of the gospel,” he writes, “I hope may be true, though the history of the Church be fabulous.”[180] But his argument against post-Apostolic miracles is so strictly naturalistic that no vigilant reader could fail to realize its fuller bearing upon all miracles whatsoever. With Hume and Francklin, he insisted that facts incredible in themselves could not be established by any amount or kind of testimony; and he suggested no measure of comparative credibility as between the two orders of miracle. With the deists in general, he argued that knowledge “either of the ways or will of the Creator” was to be had only through study of “that revelation which he made of himself from the beginning in the beautiful fabric of this visible world.”[181] An antagonist accordingly wrote that his theses were: “First, that there were no miracles wrought in the primitive Church; Secondly, that all the primitive fathers were fools or knaves, and most of them both one and the other. And it is easy to observe, the whole tenor of your argument tends to prove, Thirdly, that no miracles were wrought by Christ or his apostles; and Fourthly, that these too were fools or knaves, or both.”[182] A more temperate opponent pressed the same point in less explosive language. Citing Middleton’s demand for an inductive method, this critic asks with much point: “What does he mean by ‘deserting the path of Nature and experience,’ but giving in to the belief of any miracles, and acknowledging the reality of events contrary to the known effects of the established Laws of Nature?”[183]
No other answer was seriously possible. In the very act of ostentatiously terming Tindal an “infidel,” Middleton describes an answer made to him by the apologist Chapman as a sample of a kind of writing which did “more hurt and discredit” to Christianity “than all the attacks of its open adversaries.”[184] In support of the miracles of the gospel and the apostolic history he offers merely conventional pleas: against the miracles related by the Fathers he brings to bear an incessant battery of destructive criticism. We may sum up that by the middle of the eighteenth century the essentials of the Christian creed, openly challenged for a generation by avowed deists, were abandoned by not a few scholars within the pale of the Church, of whom Middleton was merely the least reticent. After his death was published his Vindication of the Inquiry (1751); and in his collected works (1752) was included his Reflections on the Variations or Inconsistencies which are found among the Four Evangelists, wherein it is demonstrated that “the belief of the inspiration and absolute infallibility of the evangelists seems to be more absurd than even that of transubstantiation itself.”[185] The main grounds of orthodoxy were thus put in doubt in the name of a critical orthodoxy. In short, the deistic movement had done what it lay in it to do. The old evangelical or pietistic view of life was discredited among instructed people, and in this sense it was Christianity that had “decayed.” Its later recovery was economic, not intellectual.
