By the word critic, at this day so frequent in all conversations, there have sometimes been distinguished three very different species of mortal men, according as I have read in ancient books and pamphlets. For first, by this term were understood such persons as invented or drew up rules for themselves and the world, by observing which a careful reader might be able to pronounce upon the productions of the learned, form his taste to a true relish of the sublime and the admirable, and divide every beauty of matter or of style from the corruption that apes it. In their common perusal of books, singling out the errors and defects, the nauseous, the fulsome, the dull, and the impertinent, with the caution of a man that walks through Edinburgh streets in a morning, who is indeed as careful as he can to watch diligently and spy out the filth in his way; not that he is curious to observe the colour and complexion of the ordure or take its dimensions, much less to be paddling in or tasting it, but only with a design to come out as cleanly as he may. These men seem, though very erroneously, to have understood the appellation of critic in a literal sense; that one principal part of his office was to praise and acquit, and that a critic who sets up to read only for an occasion of censure and reproof is a creature as barbarous as a judge who should take up a resolution to hang all men that came before him upon a trial. Again, by the word critic have been meant the restorers of ancient learning from the worms, and graves, and dust of manuscripts. Now the races of these two have been for some ages utterly extinct, and besides to discourse any further of them would not be at all to my purpose. The third and noblest sort is that of the true critic, whose original is the most ancient of all. Every true critic is a hero born, descending in a direct line from a celestial stem, by Momus and Hybris, who begat Zoilus, who begat Tigellius, who begat Etcætera the elder, who begat Bentley, and Rymer, and Wotton, and Perrault, and Dennis, who begat Etcætera the younger.
