In this work, when it shall be found that much is omitted, let it not be forgotten that much likewise is performed; and though no book was ever spared out of tenderness to the authour, and the world is little solicitous to know whence proceeded the faults of that which it condemns; yet it may gratify curiosity to inform it, that the English Dictionary was written with little assistance of the learned, and without any patronage of the great; not in the soft obscurities of retirement, or under the shelter of academick bowers, but amidst inconvenience and distraction, in sickness and in sorrow: and it may repress the triumph of malignant criticism to observe, that if our language is not here fully displayed, I have only failed in an attempt which no human powers have hitherto completed. If the lexicons of ancient tongues, now immutably fixed, and comprised in a few volumes, be yet, after the toil of successive ages, inadequate and delusive; if the aggregated knowledge, and co-operating diligence of the Italian academicians, did not secure them from the censure of Beni; if the embodied criticks of France, when fifty years had been spent upon their work, were obliged to change its oeconomy, and give their second edition another form, I may surely be contented without the praise of perfection, which, if I could obtain, in this gloom of solitude, what would it avail me? I have protracted my work till most of those whom I wished to please, have sunk into the grave, and success and miscarriage are empty sounds: I therefore dismiss it with frigid tranquillity, having little to fear or hope from censure or from praise.
