Some authors write nonsense in a clear style, and others sense in an obscure one; some can reason without being able to persuade, others can persuade without being able to reason; some dive so deep that they descend into darkness, and others soar so high that they give us no light; and some, in a vain attempt to be cutting and dry, give us only that which is cut and dried. We should labor, therefore, to treat with ease of things that are difficult; with familiarity, of things that are novel; and with perspicuity, of things that are profound.
