So certainly is weariness the concomitant of our undertakings, that every man, in whatever he is engaged, consoles himself with the hope of change; if he has made his way by assiduity to publick employment, he talks among his friends of the delight of retreat; if by the necessity of solitary application he is secluded from the world, he listens with a beating heart to distant noises, longs to mingle with living beings, and resolves to take hereafter his fill of diversions, or display his abilities on the universal theatre, and enjoy the pleasure of distinction and applause. Every desire, however innocent, grows dangerous, as by long indulgence it becomes ascendant in the mind. When we have been much accustomed to consider any thing as capable of giving happiness, it is not easy to restrain our ardour or forbear some precipitation in our advances, and irregularity in our pursuits. He that has cultivated the tree, watched the swelling bud and opening blossom, and pleased himself with computing how much every sun and shower add to its growth, scarcely stays till the fruit has obtained its maturity, but defeats his own cares by eagerness to reward them. When we have diligently laboured for any purpose, we are willing to believe that we have attained it, and, because we have already done much, too suddenly conclude that no more is to be done. All attraction is increased by the approach of the attracting body. We never find ourselves so desirous to finish, as in the latter part of our work, or so impatient of delay, as when we know that delay cannot be long. Thus unseasonable importunity of discontent may be partly imputed to langour and weariness, which must always oppress those more whose toil has been longer continued; but the greater part usually proceeds from frequent contemplation of that ease which is now considered as within reach, and which, when it has once flattered our hopes, we cannot suffer to be withheld. In some of the noblest compositions of wit, the conclusion falls below the vigour and spirit of the first books; and as a genius is not to be degraded by the imputation of human failings, the cause of this declension is commonly sought in the structure of the work, and plausible reasons are given why in the defective part less ornament was necessary, or less could be admitted. But, perhaps, the author would have confessed, that his fancy was tired, and his perseverance broken; that he knew his design to be unfinished, but that, when he saw the end so near, he could no longer refuse to be at rest.
