without--there is so much irresistible truth, beauty, and consistency in it--yet it is for one of your age, I think I ought to say for yourself, to set about it." What were those "openings to truth and direct paths leading to it?" Were they merely the delusive visions of an old man's fancies, or had he really formed wider conceptions of science, and pictured to himself more precise and fertile methods of reaching it? The sciences, it is needless to observe, have grown vastly since Locke's day; the methods of scientific research are far more numerous, more accurate, richer in their results. Had Locke, in his thoughts at this time, at all anticipated the courses which inquiry and knowledge have since taken? The letter to Collins, from which I have just quoted, was written on Oct. 29, 1703. Within a year of that date the end came. The wonder, indeed, is that, with his persistent malady, aggravated apparently in these latter years with other disorders, Locke's life had continued so long. The reasons are probably to be sought in his unfailing cheerfulness, in the variety of interests which diverted his mind from the thought of his own ailments, and in the judicious manner in which he regulated his exercise and diet. Of these personal traits something may conveniently here be said. The remarkable cheerfulness of his disposition, his lively sense of humour, and his power of extracting amusement from all that was going on around him, have frequently come before us in the course of this biography. His temper was not moody, like that of so many men of letters, but pre-eminently sociable. When not actually engaged in his studies, he always liked to be in company, and enjoyed especially the society of young people and children. He had a happy knack of talking to his companions for the time being on the subjects which interested them most, and in this way he gained a very extensive knowledge of the various kinds of business, and of a variety of arts and crafts. To working people he was often able to give very useful hints as to their own employments. This union of conversational qualities, grave and gay, invariably made him a welcome addition to any company, young or old, gentle or simple. An even temper, and a combination of happy gifts of this kind, will carry a man through much suffering, bodily and mental. From any mental troubles, on his own account, Locke seems, during these latter years of his life, to have been remarkably free. From bodily suffering he was rarely exempt, but he always endured it with resignation, and endeavoured to obviate its causes by every precaution, which his prudence or medical skill suggested. Thus, we have seen that, whenever it was possible, he preferred the quiet life and pure air of the country to the many attractions which the capital must have offered to a man with his wide acquaintance, and with so many political and literary interests. In diet he practised an abstemiousness very rare among men of that age.
