I have one word to say upon the subject of profound writers, who are grown very numerous of late; and I know very well the judicious world is resolved to list me in that number. I conceive therefore, as to the business of being profound, that it is with writers as with wells - a person with good eyes may see to the bottom of the deepest, provided any water be there: and often when there is nothing in the world at the bottom besides dryness and dirt, though it be but a yard and a-half under-ground, it shall pass, however, for wondrous deep upon no wiser reason than because it is wondrous dark
