" in lexicography, as in other arts, naked science is too delicate for the purposes of life. The value of a work must be estimated by its use; it is not enough that a dictionary delights the critick, unless, at the same time, it instructs the learner; as it is to little purpose that an engine amuses the philosopher by the subtilty of its mechanism, if it requires so much knowledge in its application as to be of no advantage to the common workman. "
