It was thus that Berkeley became known to “men of merit” in that brilliant society. He was also brought among persons on whom he would hardly have conferred this title. He tells Percival that he had attended several free-thinking clubs, in the pretended character of a learner, and that he there heard Anthony Collins, author of “the bold and pernicious book on free-thinking,” boast “that he was able to demonstrate that the existence of God is an impossible supposition.” The promised “demonstration” seems to have been Collins' Inquiry Concerning Human Liberty, which appeared two years later, according to which all that happens in mind and matter is the issue of natural necessity. Steele invited Berkeley to contribute [pg xl] to the Guardian during its short-lived existence between March and September, 1713. He took the Discourse of Collins for the subject of his first essay. Three other essays are concerned with man's hope of a future life, and are among the few passages in his writings in which his philosophy is a meditation upon Death.
In May, Percival writes to him from Dublin that he hears the “new book of Dialogues is printed, though not yet published, and that your opinion has gained ground among the learned; that Mr. Addison has come over to your view; and that what at first seemed shocking is become so familiar that others envy you the discovery, and make it their own.” In his reply in June, Berkeley mentions that “a clergyman in Wiltshire has lately published a treatise wherein he advances something published three years ago in my Principles of Human Knowledge.” The clergyman was Arthur Collier, author of the Clavis Universalis, or demonstration of the impossibility of an external world[6].
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 [pg xli] 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 [pg xlii] 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. One of the former happened to be the author of the Voyage to St. Kilda and the Account of the Western Isles[7]. We were good company on the road; and that day se'ennight came to Paris. I have since been taken up in viewing churches, convents, palaces, colleges, &c., which are very numerous and magnificent in this town. The splendour and riches of these things surpasses belief; but it were endless to descend to particulars. I was present at a disputation in the Sorbonne, which indeed had much of the French fire in it. I saw the Irish and the English Colleges. In the latter I saw, enclosed in a coffin, the body of the late King James.... To-morrow I intend to visit Father Malebranche, and discourse him on certain points.”
The Abbé D'Aubigné, as he informs Percival, was to introduce him to Malebranche, then the chief philosopher of France, whose Vision of the world in God had some affinity with Berkeley's own thought. Unfortunately we have no record of the intended interview with the French idealist, who fourteen years before had been visited by Addison, also on his way to Italy, when Malebranche expressed great regard for the English nation, and admiration for Newton; but he shook his head when Hobbes was mentioned, whom he ventured to disparage as a “poor silly creature.” Malebranche died nearly two years after Berkeley's proposed interview; and according to a story countenanced by Dugald Stewart, Berkeley was the “occasional cause” of his death. He found the venerable Father, we are told, in a cell, cooking, in a pipkin, a medicine for a disorder with which he was troubled. The conversation naturally turned on Berkeley's system, of which [pg xliii] Malebranche had received some knowledge from a translation. The issue of the debate proved tragical to poor Malebranche. In the heat of disputation he raised his voice so high, and gave way so freely to the natural impetuosity of a man of genius and a Frenchman, that he brought on a violent increase of his disorder, which carried him off a few days after[8]. This romantic tale is, I suspect, mythical. The Percival correspondence shews that Berkeley was living in London in October, 1715, the month in which Malebranche died, and I find no trace of a short sudden visit to Paris at that time.
After a month spent in Paris, another fortnight carried Berkeley and two travelling companions to Italy through Savoy. They crossed Mont Cenis on New Year's Day in 1714—“one of the most difficult and formidable parts of the Alps which is ever passed over by mortal man,” as he tells Prior in a letter from Turin. “We were carried in open chairs by men used to scale these rocks and precipices, which at this season are more slippery and dangerous than at other times, and at the best are high, craggy, and steep enough to cause the heart of the most valiant man to melt within him.” At the end of other six weeks we find him at Leghorn, where he spent three months, “while my lord was in Sicily.” He “prefers England or Ireland to Italy: the only advantage is in point of air.” From Leghorn he writes in May a complimentary letter to Pope, on the occasion of the Rape of the Lock: “Style, painting, judgment, spirit, I had already admired in your other writings; but in this I am charmed with the magic of your invention, with all those images, allusions, and inexplicable beauties which you raise so surprisingly, and at the same time so naturally, out of a trifle.... I remember to have heard you mention some [pg xliv] half-formed design of coming to Italy. What might we not expect from a muse that sings so well in the bleak climate of England, if she felt the same warm sun and breathed the same air with Virgil and Horace.” In July we find Berkeley in Paris on his way back to England. He had “parted from Lord Peterborough at Genoa, where my lord took post for Turin, and thence designed passing over the Alps, and so through Savoy, on his way to England.” In August they are in London, where the aspect of English politics was changed by the death of the Queen in that month. He seems to have had a fever soon after his return. In October, Arbuthnot, in one of his chatty letters to Swift, writes thus: “Poor philosopher Berkeley has now the idea of health, which was very hard to produce in him, for he had an idea of a strange fever upon him, so strange that it was very hard to destroy it by introducing a contrary one.”
Our record of the two following years is a long blank, first broken by a letter to Percival in July, 1715, dated at London. Whether he spent any time at Fulham with Lord Peterborough after their return from Italy does not appear, nor whether he visited Ireland in those years, which is not likely. We have no glimpses of brilliant London society as in the preceding year. Steele was now in Parliament. Swift had returned to Dublin, and Addison was the Irish chief secretary. But Pope was still at Binfield, among the glades of Windsor, and Berkeley congratulated him after receiving the first volume of his Homer. Of his own literary pursuits we hear nothing. Perhaps the Second Part of the Principles, which was lost afterwards in his travels, engaged him. In the end of July he wrote to Lord Percival[9] from Flaxley[10] on the Severn; and in August, September, October, and November he wrote from London, chiefly interested in [pg xlv] reports about “the rebels in Scotland,” and “the forces under Lord Mar, which no doubt will languish and disperse in a little time. The Bishop of Bristol assured me the other day that the Court expect that the Duke of Orleans would, in case of need, supply them with forces against the Pretender.” Our next glimpse of him is in May, 1716, when he writes to Lord Percival that he is “like soon to go to Ireland, the Prince of Wales having recommended him to the Lords Justices for the living of St. Paul's in Dublin.” This opening was soon closed, and the visit to Ireland was abandoned. A groundless suspicion of Jacobitism was not overcome by the interest of Caroline, Princess of Wales. In June, 1716, Charles Dering wrote from Dublin, that “the Lords Justices have made a strong representation against him.” He had to look elsewhere for the immediate future.
We find him at Turin in November, 1716, with a fresh leave of absence for two years from his College. It seems that Ashe, Bishop of Clogher, had engaged him as travelling tutor to his son, a means not then uncommon for enabling young authors of moderate fortune to see new countries and mix with society. Addison had visited Italy in this way sixteen years before, and Adam Smith long afterwards travelled with the young Duke of Buccleuch. With young Ashe, Berkeley crossed Mont Cenis a second time. They reached Rome at the beginning of 1717. His Journal in Italy in that year, and occasional letters to Percival, Pope, and Arbuthnot, shew ardent interest in nature and art. With the widest views, “this very great though singular sort of man descended into a minute detail, and begrudged neither pains nor expense for the means of information. He travelled through a great part of Sicily on foot; clambered over the mountains and crept into the caverns, to investigate its natural history and discover the causes of its volcanoes; and I have known him sit for hours in forges and foundries to inspect their [pg xlvi] successive operations[11].” If the Journal had been transformed by his own hand into a book, his letter to Pope from Inarime shews that the book might have rivalled Addison's Remarks on Parts of Italy in grace of style and large human interest.
In the summer of 1720 we find the travellers at Florence, afterwards for some time at Lyons, and in London at the beginning of the next year. On the way home his metaphysical inspiration was revived. The “Cause of Motion” had been proposed by the French Academy as the subject of a prize dissertation. The subject gave an opportunity for further unfolding his early thought. In the Principles and the Dialogues he had argued for the necessary dependence of matter, for its concrete substantial reality, upon living percipient mind. He would now shew its powerlessness as it is presented to us in sense. The material world, chiefly under the category of substance, inspired the Principles. The material world, under the category of cause or power, inspired the De Motu. This Latin Essay sums up the distinctive thought of Berkeley, as it appears in the authorship of his early life. Moles evolvit et agitat mentes might be taken as the formula of the materialism which he sought to dissolve. Mens percipit et agitat molem significantem, cujus esse est percipi expresses what Berkeley would substitute for the materialistic formula.
