Note 162 — Chapter XVI · BRITISH FREETHOUGHT IN THE EIGHTEENTH CENTURY

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.
