CHAPTER IV. RESIDENCE IN HOLLAND.--THE REVOLUTION.--RETURN TO ENGLAND.--PUBLICATION OF THE "ESSAY" AND OTHER WORKS. Locke must have landed in Holland in one of the autumn months of 1683, being then about fifty-one years of age. We are not able, however, to trace any of his movements till the January of 1683-84, when he was present, by invitation of Peter Guenellon, the principal physician of Amsterdam, at the dissection of a lioness which had been killed by the intense cold of the winter. Through Guenellon, whom he had met during his stay in Paris, he must have made the acquaintance of the principal literary and scientific men at that time residing in or near Amsterdam. Amongst these was Philip van Limborch, then professor of theology among the Arminians or Remonstrants. The Arminians (called Remonstrants on account of the remonstrance which they had presented to the States-General in 1610) were the latitudinarians of Holland, and, though they had been condemned by the Synod of Dort in 1619, and had been subjected to a bitter persecution by the Calvinist clergy for some years following, were now a fairly numerous body, possessing a theological seminary, and exercising a considerable influence, not only in their own country, but over the minds of the more liberal theologians throughout Europe. The undogmatic, tolerant, and, if I may use the expression, ethical character of the Remonstrant theology must have had great attractions for Locke, and he and Limborch, united by many common sentiments, subsequently became fast friends.
