In the autumn of 1684 Locke made a tour of the country, noting, as was usual with him, all objects and matters of interest, and evidently benefiting much in health by the diversion of travelling. Indeed, we are somewhat surprised to hear that his health derived more advantage from the air of Holland than from that of Montpellier. What, however, he put down to climate was, perhaps, at least equally due to pleasant companionship, and to the variety of interests—political, commercial, literary, and theological—which the Dutch nation at that time so pre-eminently afforded. Amongst the objects which attracted his attention was a sect of communistic mystics established near Leeuwarden. "They receive," he says, "all ages, sexes, and degrees, upon approbation. They live all in common; and whoever is admitted is to give with himself all he has to Christ the Lord—that is, the Church—to be managed by officers appointed by the Church. These people, however, were very shy to give an account of themselves to strangers, and they appeared inclined to dispense their instruction only to those whom 'the Lord,' as they say, 'had disposed to it,' and in whom they saw 'signs of grace;' which 'signs of grace' seem to me to be, at last, a perfect submission to the will and rules of their pastor, Mr. Yonn, who, if I mistake not, has established to himself a perfect empire over them. For though their censures and all their administrations be in appearance in their Church, yet it is easy to perceive how at last it determines in him. He is dominus factotum; and though I believe they are, generally speaking, people of very good and exemplary lives, yet the tone of voice, manner, and fashion of those I conversed with seemed to make one suspect a little of Tartuffe." After Locke's experiences of the Puritan ministers in his early life, the character of Mr. Yonn was, probably, by no means new to him, though he now repeated his acquaintance with it under novel circumstances.

In November Locke was again in Amsterdam, and here he heard of Dr. Fell's "moneo," summoning him back to Christ Church. At first it would seem that he resolved to comply with it, but the intelligence of the "moneo" must soon have been followed by that of his deprivation, and thus he was saved from the dangers which might have befallen him had he returned to England. In more ways than one, his continued absence abroad was probably an advantage to him. "In Holland," says Lady Masham, "he had full leisure to prosecute his thoughts on the subject of Human Understanding—a work which, in probability, he never would have finished had he continued in England." The winter of this year was spent in Utrecht and devoted to study—probably to the preparation of the Essay on Human Understanding. But this quiet mode of life was quickly coming to an end. On the 6th of February, 1684-85, Charles the Second had died; and, though the succession of the Duke of York was at first undisputed, Monmouth, the natural son of the late king, was soon persuaded by his impatient and injudicious followers to head the insurrection which resulted in his defeat and execution. From Monmouth's intrigues Locke had always held aloof, "having no such high opinion of the Duke of Monmouth as to expect anything from his undertaking." But prudence, in those days of fierce political hatred and unblushing fabrications, was often of very little avail. Locke was well known as an adherent of Shaftesbury, and Shaftesbury had long and ardently favoured Monmouth's pretensions. Moreover, stories tending to discredit him with the advisers of the Court, and to connect his name with the plots of the other exiles, were probably circulating pretty freely at this time. On the 7th of May—a few days after Argyle had set out on his ill-starred expedition to Scotland, and while Monmouth was still preparing for his descent on the west coast of England—Colonel Skelton, who had been sent over as a special envoy to the Hague, presented to the States-General a list of persons regarded as dangerous by the English Government, and demanded their surrender. On this list Locke's name stood last, having been added, we are told, by Sir George Downing, the English representative at the Dutch Court, but whether or not in pursuance of further instructions from home we do not know. Locke was at this time living at Utrecht, and it was at once arranged that he should be concealed in the house of Dr. Veen, of Amsterdam, the father-in-law of his old acquaintance, Dr. Guenellon. Though it was necessary, for appearance' sake, that he should keep strictly to his hiding-place, he does not seem to have incurred any real danger. The municipal authorities of Amsterdam had too great a horror of Popery and too much sympathy with liberty to show any marked zeal in carrying out the wishes of the English king; nor does the Prince of Orange himself appear to have been very eager to hunt out the fugitives, provided they went through the decent ceremony of concealing themselves from the ministers of justice. To Locke the confinement was doubtless irksome; but he was solaced by the visits of his friends, especially of Limborch, and the monotony of his solitude was broken by a visit of a few weeks to Cleve. Here, however, he does not appear to have felt so safe as at Amsterdam; and, consequently, he soon returned to his old quarters, assuming the name of Dr. Van der Linden, as at Cleve he had assumed that of Lamy. Meanwhile, two of his friends in England—William Penn, the celebrated Quaker, and the Earl of Pembroke, to whom he afterwards dedicated the Essay—were moving the king for a pardon. The latter, writing to Locke on the 20th of August, informs him that the king "bid me write to you to come over; I told him I would then bring you to kiss his hand, and he was fully satisfied I should." Locke, however, appears to have had little confidence in the king's sincerity, and, perhaps, no desire to compromise any political action that might be open to him in the future by making formal submission to a monarch who was tolerably certain to work out his own ruin. He still remained in concealment, and replied that, "having been guilty of no crime, he had no occasion for a pardon." But in May, 1686, all fear of arrest was removed by the appearance of a new proclamation of the States-General, in which his name was not included, and henceforth he was enabled to move about with perfect freedom.

The name of Limborch, one of the friends whom Locke made in Holland, has already been mentioned. A long series of letters which passed between them, beginning with Locke's arrival at Cleve in September, 1685, and ending only a few weeks before his death, is still extant, though some are still unpublished. This correspondence is interesting, not only as throwing light on Locke's pursuits, but also as affording a free expression of his theological opinions. Thus, in a letter written to Limborch soon after his arrival at Cleve, with reference to a work recently published by Le Clerc, he acknowledges his perplexities respecting the plenary inspiration of the Bible. "If all things which are contained in the sacred books are equally to be regarded as inspired, without any distinctions, then we give philosophers a great handle for doubting of our faith and sincerity. If, on the contrary, some things are to be regarded as purely human, how shall we establish the divine authority of the Scriptures, without which the Christian religion will fall to the ground? What shall be our criterion? Where shall we draw the line?" He applies to Limborch for help. "For many things which occur in the canonical books, long before I read this treatise, have made me anxious and doubtful, and I shall be most grateful if you could remove my scruples." From the character of his theological writings, composed during the latter years of his life, it would appear that these scruples were afterwards either removed or set aside.

With Le Clerc (Joannes Clericus) himself Locke first became personally acquainted after his return to Amsterdam in the winter of 1685-86. Le Clerc was still young, having been born at Geneva in 1657, but he had already acquired considerable reputation both as a philosopher and as a theologian. As a philosopher, he had at first embraced the doctrines of Descartes, but, in after-life, he leaned rather to those views which, a few years after the time of which I am writing, became famous by the publication of Locke's Essay. As a divine, his theology was liberal and critical beyond even that of the Remonstrant School. He questioned the Mosaic authorship of the Pentateuch, regarded some of the books of the old Testament as of purely human origin, and, in his treatment of the miracles and of Christian doctrine, rationalized so far as to expose himself to the charge of Socinianism, though he himself warmly repudiated the imputation. In literary activity and enterprise he yielded to no other author of the age. Such a man, full of energy and of novel views, ready to entertain and discuss any question of interest in theology, criticism, or philosophy, must have been peculiarly acceptable to an exile like Locke, whose mind was now engaged with just the same problems that were occupying Le Clerc. The intimacy between the two students, though never so affectionate as that between Locke and Limborch, soon became a close one. Though widely separated in age, and though differing, probably, in many of their specific opinions, they were conscious that they were travelling the same road—a way then little frequented—the way which led from the received tenets of the churches and the schools to the arena of free inquiry and impartial investigation.

In the winter of 1685-86, Locke, while still hiding in Dr. Veen's house, employed himself in writing the famous Epistola de Tolerantia, addressed to Limborch. This tract was not, however, published till 1689, when it was almost immediately translated into English, Dutch, and French. Of the opinions expressed in this and the other letters on Toleration I shall have occasion to speak hereafter, when describing Locke's theological views. It must be recollected that, though now in his fifty-fourth year, he had as yet published nothing of any importance. He had, indeed, for several years been slowly putting together the materials for many books; but it is possible that his natural modesty, together with what seems to have been an excessive prudence, might have prevented him from giving any of his thoughts to the world, at least during his lifetime, had it not been for the fortunate circumstances which brought him into contact with Le Clerc. At the time when the two friends were introduced to one another, Le Clerc was projecting the Bibliothèque Universelle, one of the earliest literary and scientific reviews, and to this Locke soon became a constant contributor. In the July number of 1686 appears his method of a Commonplace Book, under the title, Méthode Nouvelle de dresser des Recueils. The ice was now broken, and from this time onwards we shall find his publications follow one another in rapid succession.

In September, 1686, Locke moved again to Utrecht, intending, apparently, to make a prolonged residence there; but in December, for some mysterious reason with which we are not acquainted, though connected in all probability with English politics, he was threatened with expulsion from the city, and was obliged to return to Amsterdam. It seems, from his correspondence with Limborch, that he did not wish this expulsion to be talked about. At the same time, he accepted stoically the inconveniences to which it put him. "These are the sports of fortune, or rather the ordinary chances of human life, which come as naturally as wind and rain to travellers." At Amsterdam he remained for two months as the guest of his old friend, Dr. Guenellon, and then removed to Rotterdam, where, with occasional breaks, he resided during the rest of his stay in Holland. This removal was undoubtedly connected with the turn which English politics were now taking at the Dutch Court. Monmouth being now out of the way, the only quarter to which those who were weary of the Stuart despotism could look for redress was the House of Orange. Secret negotiations were at this time going on with the Prince and Princess, and there can be no doubt that Locke was taking an active share in the schemes that were in preparation. Rotterdam was within a short distance of the Hague, and also a convenient place for carrying on a correspondence with England as well as for meeting the Englishmen who landed in Holland. As soon as Locke arrived at Rotterdam his hands seem to have been tolerably full of political business. Writing to Limborch in February, 1686-87, he says, "To politics I gave but little thought at Amsterdam; here I cannot pay much attention to literature." Mr. Fox Bourne conjectures that it was through Lord Mordaunt, afterwards Earl of Peterborough, who shortly before this time had taken up his residence in Holland, that Locke was brought into personal relations with the Prince and Princess. Any way, these relations gradually ripened into friendship, and a mutual feeling of respect and admiration seems soon to have grown up between him and the royal couple.

While at Rotterdam, Locke resided with Benjamin Furly, an English Quaker, who was a merchant of considerable wealth and a great book-collector. At Furly's death, in 1714, the sale-catalogue of his books occupied nearly 400 pages. Locke was thus at no loss for the instruments of his trade, and, notwithstanding his preoccupation in politics, he seems to have been working with fair assiduity at the Essay and on other literary subjects. In the number of the Bibliothèque Universelle for January, 1687-88, appeared an abstract of the Essay, translated into French by Le Clerc, from a manuscript written by Locke, which is still extant. The epitome was announced as communicated by Monsieur Locke, and a note was appended inviting criticisms, if anything false, obscure, or defective were remarked in the system. After the review had appeared, separate copies of the epitome were struck off, and the opuscule, with a short dedication to the Earl of Pembroke, was published in a separate form. Locke went to Amsterdam for the purpose of superintending the printing of the epitome, and appears to have been sorely tried by the "drunken" and "lying" workmen, who, however, were all "good Christians," "orthodox believers," and "marked for salvation by the distinguishing L that stands on their door-posts, or the funeral sermon that they may have for a passport if they will go to the charge of it." On the 29th of February he returned to Furly's house, where he seems to have lived in great comfort, and on most intimate and affectionate terms with the family. One of the sons, a little boy of four or five years old, named Arent, was a special favourite, and is playfully alluded to in the letters to Furly as "my little friend!" Kindness to children seems always to have been one of Locke's characteristics, as it is of all men of simple manners and warm hearts.

It was on the 1st of November, 1688, that William of Orange set out on his expedition to England. Locke still remained in Holland, and appears to have had frequent interviews with the Princess Mary, who was waiting till she could with safety join her husband. At last the word was given from England, and, after being detained for some time by unfavourable weather, the royal party, accompanied by Locke and Lady Mordaunt, left the Hague on the 11th of February, 1688-89. They arrived at Greenwich on the following day. It was with mixed feelings that Locke took leave of the country where he had been entertained so long, and where he had formed so many warm and congenial friendships. Writing to Limborch shortly before his departure, he says, "There are many considerations which urge me not to miss this opportunity of sailing: the expectation of my friends; my private affairs, which have now been long neglected; the number of pirates in the channel; and the charge of the noble lady (Lady Mordaunt) with whom I am about to travel. But I trust that you will believe me when I say that I have found here another country, and I might almost say other relations; for all that is dearest in that expression—good-will, love, kindness—bonds that are stronger than blood—I have experienced amongst you. It is owing to this fellow-feeling, which has always been shown to me by your countrymen, that, though absent from my own people and exposed to every kind of trouble, I have never yet felt sick at heart."[1] Still, it must have been with a thrill of delight that, after an absence of more than five years, he once more stepped on the shores of his native land, and felt that a new era of liberty and glory had dawned for her.

[1] It should be mentioned, perhaps, that the correspondence between Locke and Limborch is in Latin.

About a week after his arrival in England, Locke was offered, through Lord Mordaunt, the post of ambassador to Frederick the First, Elector of Brandenburg. The letter to Lord Mordaunt, in which he declines the post, shows the feeble condition in which, notwithstanding all his precautions, his health still continued. "It is the most touching displeasure I have ever received from that weak and broken constitution of my health, which has so long threatened my life, that it now affords me not a body suitable to my mind in so desirable an occasion of serving his Majesty.... What shall a man do in the necessity of application and variety of attendance on business who sometimes, after a little motion, has not breath to speak, and cannot borrow an hour or two of watching from the night without repaying it with a great waste of time the next day?" But there was another reason, besides his health, why he could not accept a mission to the Court of Brandenburg. "If I have reason to apprehend the cold air of the country, there is yet another thing in it as inconsistent with my constitution, and that is their warm drinking." It was true that he might oppose obstinate refusal, but then that would be to take more care of his own health than of the king's business. "It is no small matter in such stations to be acceptable to the people one has to do with, in being able to accommodate one's self to their fashions; and I imagine, whatever I may do there myself, the knowing what others are doing is at least one half of my business, and I know no such rack in the world to draw out men's thoughts as a well-managed bottle. If, therefore, it were fit for me to advise in this case, I should think it more for the king's interest to send a man of equal parts that could drink his share than the soberest man in the kingdom." But, though Locke shrank from this post, the importance of which could hardly be exaggerated, for Frederick was the ally on whom William most confided in his opposition to Louis the Fourteenth, he was ready to place his services at the disposal of the Government for domestic work. "If there be anything wherein I may flatter myself I have attained any degree of capacity to serve his Majesty, it is in some little knowledge I perhaps may have in the constitutions of my country, the temper of my countrymen, and the divisions amongst them, whereby I persuade myself I may be more useful to him at home, though I cannot but see that such an employment would be of greater advantage to myself abroad, would but my health assent to it." The disinterested patriotism of this letter was only of a piece with the whole of Locke's political life. He was next offered the embassy to Vienna, and, in fact, invited to name any diplomatic appointment which he would be prepared to accept; but he regarded his health as an insuperable bar to work of this kind at so critical a time in the history of Europe. Having declined all foreign employment, he was now named a Commissioner of Appeals, an office with small emolument and not much work, which he appears to have retained during the remainder of his life. This office seems to have been given to him partly as a compensation for the arrears of salary due under the late Government; for, with an exhausted exchequer, it was impossible to satisfy such claims by immediate payment.
