principles of toleration, which were agreeable to the sentiments of his enlightened mind; but some of the clergy, jealous of such provisions as might prove an obstacle to their ascendancy, expressed their disapprobation of them, and procured an additional article to be inserted, securing the countenance and support of the state only to the exercise of religion according to the discipline of the established church. Mr. Locke still retained his student's place at Christ-church, and made frequent visits to Oxford, for the sake of consulting books in the prosecution of his studies, and for the benefit of change of air. At lord Ashley's he inspected the education of his lordship's only son, who was then about sixteen years of age; and executed that province with the greatest care, and to the entire satisfaction of his noble patron. As the young lord was but of a weakly constitution, his father thought proper to marry him early, lest the family should become extinct by his death. And, since he was too young, and had too little experience to choose a wife for himself, and lord Ashley had the highest opinion of Mr. Locke's judgment, as well as the greatest confidence in his integrity, he desired him to make a suitable choice for his son. This was a difficult and delicate task: for though lord Ashley did not insist on a great fortune for his son, yet he would have him marry a lady of a good family, an agreeable temper, a fine person, and, above all, of good education and good understanding, whose conduct would be very different from that of the generality of court ladies. Notwithstanding the difficulties attending such a commission, Mr. Locke undertook it, and executed it very happily. The eldest son by this marriage, afterwards the noble author of the Characteristics, was committed to the care of Mr. Locke in his education, and gave evidence to the world of the master-hand which had directed and guided his genius.
In 1670, and in the following year, Mr. Locke began to form the plan of his Essay on Human Understanding, at the earnest request of some of his friends, who were accustomed to meet in his chamber, for the purpose of conversing on philosophical subjects; but the employments and avocations which were found for him by his patron, would not then suffer him to make any great progress in that work. About this time, it is supposed, he was made fellow of the Royal Society. In 1672, lord Ashley, having been created earl of Shaftesbury, and raised to the dignity of lord high chancellor of England, appointed Mr. Locke secretary of the presentations; but he held that place only till the end of the following year, when the earl was obliged to resign the great seal.
