Nor was the sublime more within their reach than the pathetic; for they never attempted that comprehension and expanse of thought which at once fills the whole mind, and of which the first effect is sudden astonishment, and the second rational admiration. Sublimity is produced by aggregation, and littleness by dispersion. Great thoughts are always general, and consist in positions not limited by exceptions, and in descriptions not descending to minuteness. It is with great propriety that subtlety, which in its original import means exility of particles, is taken in its metaphorical meaning for nicety of distinction. Those writers who lay on the watch for novelty could have little hope of greatness; for great things cannot have escaped former observation. Their attempts were always analytic; they broke every image into fragments: and could no more represent, by their slender conceits and laboured particularities, the prospects of nature or the scenes of life, than he who dissects a sunbeam with a prism can exhibit the wide effulgence of a summer noon. What they wanted, however, of the sublime, they endeavoured to supply by hyperbole; their amplification had no limits; they left not only reason but fancy behind them; and produced combinations of confused magnificence that not only could not be credited, but could not be imagined. Yet great labour, directed by great abilities, is never wholly lost: if they frequently threw away their wit upon false conceits, they likewise sometimes struck out unexpected truth: if their conceits were far-fetched, they were often worth the carriage. To write on their plan, it was at least necessary to read and think. No man could be born a metaphysical poet, nor assume the dignity of a writer, by descriptions copied from descriptions, by imitations borrowed from imitations, by traditional imagery and hereditary similes, by readiness of rhyme and volubility of syllables. In perusing the works of this race of authors, the mind is exercised either by recollection or inquiry; either something already learned is to be retrieved, or something new is to be examined. If their greatness seldom elevates, their acuteness often surprises; if the imagination is not always gratified, at least the powers of reflection and comparison are employed; and in the mass of materials which ingenious absurdity has thrown together, genuine wit and useful knowledge may be sometimes found, buried perhaps in grossness of expression, but useful to those who know their value; and such as, when they are expanded to perspicuity and polished to elegance, may give lustre to works which have more propriety though less copiousness of sentiment.
