There was no living name before which Smith bowed with profounder veneration than the name of Voltaire, and his recollections of their intercourse on these occasions were always among those he cherished most warmly. Few memorials, however, of their conversation remain, and these are preserved by Samuel Rogers in his diary of his visit to Edinburgh the year before Smith's death. They seem to have spoken, as was very natural, of the Duke of Richelieu, the only famous Frenchman Smith had yet met, and of the political question as to the revival of the provincial assemblies or the continuance of government by royal intendants. On this question Smith said that Voltaire expressed great aversion to the States and favoured the side of the royal prerogative. Of the Duke of Richelieu Voltaire said that he was an old friend of his, but a singular character. A few years before his death his foot slipped one day at Versailles, and the old marshal said that was the first _faux pas_ he had ever made at court. Voltaire then seems to have told anecdotes of the Duke's being bastilled and of his borrowing the Embassy plate at Vienna and never returning it, and to have passed the remark he made elsewhere that the English had only one sauce, melted butter. Smith always spoke of Voltaire with a genuine emotion of reverence. When Samuel Rogers happened to describe some clever but superficial author as "a Voltaire," Smith brought his hand down on the table with great energy and said, "Sir, there is only one Voltaire."[154] Professor Faujas Saint Fond, Professor of Geology in the Museum of Natural History in Paris, visited Smith in Edinburgh a few years before Rogers was there, and says that the animation of Smith's countenance was striking when he spoke of Voltaire, whom he had known personally, and whose memory he revered. "Reason," said Smith one day, as he showed M. Saint Fond a fine bust of Voltaire he had in his room, "reason owes him incalculable obligations. The ridicule and the sarcasm which he so plentifully bestowed upon fanatics and heretics of all sects have enabled the understanding of men to bear the light of truth, and prepared them for those inquiries to which every intelligent mind ought to aspire. He has done much more for the benefit of mankind than those grave philosophers whose books are read by a few only. The writings of Voltaire are made for all and read by all." On another occasion he observed to the same visitor, "I cannot pardon the Emperor Joseph II., who pretended to travel as a philosopher, for passing Ferney without doing homage to the historian of the Czar Peter I. From this circumstance I concluded that Joseph was but a man of inferior mind."[155]
