Berkeley’s _Three Dialogues_ were published in June. In the middle of that same month he was in Oxford, “a most delightful place,” where he spent two months, “witnessed the Act and grand performances at the theatre, and a great concourse from London and the country, amongst whom were several foreigners.” The Drury Lane Company had gone down to Oxford, and _Cato_ was on the stage for several nights. The Percival correspondence now first discloses this prolonged visit to Oxford in the summer of 1713, that ideal home from whence, forty years after, he departed on a more mysterious journey than any on this planet. In a letter from thence to Percival, he had claimed Arbuthnot as one of the converts to the “new Principle.” Percival replied that Swift demurred to this, on which Berkeley rejoins: “As to what you say of Dr. Arbuthnot not being of my opinion, it is true there has been some difference between us concerning some notions relating to the necessity of the laws of nature; but this does not touch the main points of the non-existence of what philosophers call material substance; against which he acknowledges he can assert nothing.” One would gladly have got more than this from Berkeley, about what touched his favourite conception of the “arbitrariness” of law in nature, as distinguished from the “necessity” which some modern physicists are ready vaguely to take for granted. ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ The scene now changes. On October 15 Berkeley suddenly writes from London: “I am on the eve of going to Sicily, as chaplain to Lord Peterborough, who is Ambassador Extraordinary on the coronation of the new king.” He had been recommended by Swift to the Ambassador, one of the most extraordinary characters then in Europe, who a few years before had astonished the world in the war of the Succession in Spain, and afterwards by his genius as a diplomatist: in Holland, nearly a quarter of a century before, he had formed an intimate friendship with John Locke. Ten months in France and Italy in the suite of Lord Peterborough brought the young Irish metaphysician, who had lately been introduced to the wits of London and the dons of Oxford, into a new world. It was to him the beginning of a career of wandering and social activity, which lasted, with little interruption, for nearly twenty years, during which metaphysics and authorship were in the background. On November 25 we find him in Paris, writing letters to Percival and Prior. “From London to Calais”, he tells Prior, “I came in company of a Flamand, a Spaniard, a Frenchman, and three English servants of my Lord. The three gentlemen, being of three different nations, obliged me to speak the French language (which is now familiar), and gave me the opportunity of seeing much of the world in little compass.... On November 1 (O.S.) I embarked in the stage-coach, with a company that were all perfect strangers to me. There were two Scotch, and one English gentleman.
