But because the Art of Criticism, both by Those who cannot form a true Judgment of its Effects, nor can penetrate into its Causes, (which takes in a great Number besides the Ladies;) is esteem’d only an arbitrary capricious Tyranny exercis’d on Books; I think proper to subjoin a Word or two about those Rules on which I have proceeded, and by which I have regulated myself in this Edition. By This, I flatter myself, it will appear, my Emendations are so far from being arbitrary or capricious, that They are establish’d with a very high Degree of moral Certainty. As there are very few Pages in _Shakespeare_, upon which some Suspicions of Depravity do not reasonably arise; I have thought it my Duty, in the first place, by a diligent and laborious Collation to take in the Assistances of all the older Copies. In his _Historical Plays_, whenever our _English_ Chronicles, and in his Tragedies when _Greek_ or _Roman_ Story, could give any Light; no Pains have been omitted to set Passages right by comparing my Author with his Originals: for, as I have frequently observed, he was a close and accurate Copier where-ever his _Fable_ was founded on _History_. Where-ever the Author’s Sense is clear and discoverable, (tho’, perchance, low and trivial;) I have not by any Innovation tamper’d with his Text; out of an Ostentation of endeavouring to make him speak better than the Old Copies have done. Where, thro’ all the former Editions, a Passage has labour’d under flat Nonsense and invincible Darkness, if, by the Addition or Alteration of a Letter or two, I have restored to Him both Sense and Sentiment, such Corrections, I am persuaded, will need no Indulgence. And whenever I have taken a greater Latitude and Liberty in amending, I have constantly endeavoured to support my Corrections and Conjectures by parallel Passages and Authorities from himself, the surest Means of expounding any Author whatsoever. _Cette voïe d’interpreter un Autheur par lui-même est plus sure que tous les Commentaires_, says a very learned _French_ Critick.
