For the subject, I came accidentally to write upon it. For a gentleman brought a Play to the King's Company, called, _The Duke of LERMA_; and, by them, I was desired to peruse it, and return my opinion, "Whether I thought it fit for the Stage!" After I had read it, I acquainted them that, "In my judgement, it would not be of much use for such a design, since the Contrivance scarce would merit the name of a Plot; and some of that, assisted by a disguise: and it ended abruptly. And on the person of PHILIP III., there was fixed such a mean Character; and on the daughter of the Duke of LERMA, such a vicious one: that I could not but judge it unfit to be presented by any that had a respect, not only to Princes, but indeed, to either Man or Woman." And, about that time, being to go in the country, I was persuaded by Mr. HART to make it my diversion there, that so great a hint might not be lost, as the Duke of LERMA saving himself, in his last extremity, by his unexpected disguise: which is as well in the true Story [_history_], as the old Play. And besides that and the Names; my altering the most part of the Characters, and the whole Design, made me uncapable to use much more, though, perhaps, written with higher Style and Thoughts than I could attain to. I intend not to trouble myself nor the World any more in such subjects; but take my leave of these my too long acquaintances: since that little Fancy and Liberty I once enjoyed, is now fettered in business of more unpleasant natures. Yet, were I free to apply my thoughts, as my own choice directed them; I should hardly again venture into the Civil Wars of Censures. _Ubi ... Nullos habitura triumphos_. In the next place. I must ingeniously confess that the manner of Plays, which now are in most esteem, is beyond my power to perform [p. 587]; nor do I condemn, in the least, anything, of what nature soever, that pleases; since nothing could appear to me a ruder folly, than to censure the satisfaction of others. I rather blame the unnecessary understanding of some, that have laboured to give strict Rules to things that are not mathematical; and, with such eagerness, pursuing their own seeming reasons, that, at last, we are to apprehend such Argumentative Poets will grow as strict as SANCHO PANZA's Doctor was, to our very appetites: for in the difference of Tragedy and Comedy, and of Fars [_farce_] itself, there can be no determination, but by the taste; nor in the manner of their composure. And, whoever would endeavour to like or dislike, by the Rules of others; he will be as unsuccessful, as if he should try to be persuaded into a power of believing, not what he must, but what others direct him to believe.
