In France, Hume's reputation stood far higher than in Britain; several of his works had been translated; he had exchanged letters with Montesquieu and with Helvetius; Rousseau had appealed to him; and the charming Madame de Boufflers had drawn him into a correspondence, marked by almost passionate enthusiasm on her part, and as fair an imitation of enthusiasm as Hume was capable of, on his. In the extraordinary mixture of learning, wit, humanity, frivolity, and profligacy which then characterised the highest French society, a new sensation was worth anything, and it mattered little whether the cause thereof was a philosopher or a poodle; so Hume had a great success in the Parisian world. Great nobles fêted him, and great ladies were not content unless the "gros David" was to be seen at their receptions, and in their boxes at the theatre. "At the opera his broad unmeaning face was usually to be seen entre deux jolis minois," says Lord Charlemont.[13] Hume's cool head was by no means turned; but he took the goods the gods provided with much satisfaction; and everywhere won golden opinions by his unaffected good sense and thorough kindness of heart.

Over all this part of Hume's career, as over the surprising episode of the quarrel with Rousseau, if that can be called quarrel which was lunatic malignity on Rousseau's side and thorough generosity and patience on Hume's, I may pass lightly. The story is admirably told by Mr. Burton, to whose volumes I refer the reader. Nor need I dwell upon Hume's short tenure of office in London, as Under-Secretary of State, between 1767 and 1769. Success and wealth are rarely interesting, and Hume's case is no exception to the rule.

According to his own description the cares of official life were not overwhelming.

"My way of life here is very uniform and by no means disagreeable. I have all the forenoon in the Secretary's house, from ten till three, when there arrive from time to time messengers that bring me all the secrets of the kingdom, and, indeed, of Europe, Asia, Africa, and America. I am seldom hurried; but have leisure at intervals to take up a book, or write a private letter, or converse with a friend that may call for me; and from dinner to bed-time is all my own. If you add to this that the person with whom I have the chief, if not only, transactions, is the most reasonable, equal-tempered, and gentleman-like man imaginable, and Lady Aylesbury the same, you will certainly think I have no reason to complain; and I am far from complaining. I only shall not regret when my duty is over; because to me the situation can lead to nothing, at least in all probability; and reading, and sauntering, and lounging, and dozing, which I call thinking, is my supreme happiness—I mean my full contentment."

Hume's duty was soon over, and he returned to Edinburgh in 1769, "very opulent" in the possession of £1,000 a year, and determined to take what remained to him of life pleasantly and easily. In October, 1769, he writes to Elliot:—

"I have been settled here two months, and am here body and soul, without casting the least thought of regret to London, or even to Paris.... I live still, and must for a twelvemonth, in my old house in James's Court, which is very cheerful and even elegant, but too small to display my great talent for cookery, the science to which I intend to addict the remaining years of my life. I have just now lying on the table before me a receipt for making soupe à la reine, copied with my own hand; for beef and cabbage (a charming dish) and old mutton and old claret nobody excels me. I make also sheep's-head broth in a manner that Mr. Keith speaks of for eight days after; and the Duc de Nivernois would bind himself apprentice to my lass to learn it. I have already sent a challenge to David Moncreiff: you will see that in a twelvemonth he will take to the writing of history, the field I have deserted; for as to the giving of dinners, he can now have no further pretensions. I should have made a very bad use of my abode in Paris if I could not get the better of a mere provincial like him. All my friends encourage me in this ambition; as thinking it will redound very much to my honour."

In 1770, Hume built himself a house in the new town of Edinburgh, which was then springing up. It was the first house in the street, and a frolicsome young lady chalked upon the wall "St. David's Street." Hume's servant complained to her master, who replied, "Never mind, lassie, many a better man has been made a saint of before," and the street retains its title to this day.

In the following six years, the house in St. David's Street was the centre of the accomplished and refined society which then distinguished Edinburgh. Adam Smith, Blair, and Ferguson were within easy reach; and what remains of Hume's correspondence with Sir Gilbert Elliot, Colonel Edmonstone, and Mrs. Cockburn gives pleasant glimpses of his social surroundings, and enables us to understand his contentment with his absence from the more perturbed, if more brilliant, worlds of Paris and London.

Towards London, Londoners, and indeed Englishmen in general, Hume entertained a dislike, mingled with contempt, which was as nearly rancorous as any emotion of his could be. During his residence in Paris, in 1764 and 1765, he writes to Blair:—

"The taste for literature is neither decayed nor depraved here, as with the barbarians who inhabit the banks of the Thames."
