Smith never wrote any reply to this attack, nor took any public notice of it whatever, though he had too much real human nature in him to agree with Bishop Horne’s own ethereal maxim that “a man reproached with a crime of which he knows himself to be innocent should feel no more uneasiness than if he was said to be ill when he felt himself in perfect health.” It was of course quite unjust to accuse Smith of atheism, or of desiring to propagate atheism. His published writings, which the Bishop ought in fairness to have consulted, show him to have been a Theist, and there is some ground for thinking that he believed Hume, as many others of Hume’s personal friends did, to have been a Theist likewise. Though Hume was philosophically a doubter about matter, about his own existence, about God, he did not practically think so differently from the rest of the world about any of the three as was often supposed. Dr. Carlyle always thought him a believer. Miss Mure of Caldwell, the sister of his great friend the Baron of Exchequer, says he was the most superstitious man she ever knew.[272] He told Holbach that an atheist never existed, and once, while walking with Adam Ferguson on a beautiful clear night, he stopped suddenly and exclaimed, pointing to the sky, “Can any one contemplate the wonders of that firmament and not believe that there is a God?"[273] That Smith would not have been surprised to hear his friend make such a confession is apparent from the well-known anecdote told of his absence of mind in connection with Henry Mackenzie’s story of “La Roche.” That story was written soon after Hume’s death; it was published in the Mirror in 1779, while Horne’s agitation was raging; and the author introduced Hume as one of the characters of the piece for the very purpose of presenting this more favourable view of the great sceptic’s religious position with which Mackenzie had been impressed in his own intercourse with him. Hume appears in the story as a visitor in Switzerland, an inmate of the simple household of the pastor La Roche, and after describing him as being deeply taken with the sweet and unaffected piety of this family’s life and with the faith that sustained them in their troubles, the author goes on to observe, “I have heard him long after confess that there were moments when, amidst the pride of philosophical discovery and the
