The liking or disliking of the people gives the Play the _denomination_ of "good" or "bad"; but does not really make or constitute it such. To please the people ought to be the Poet's aim [pp. 513, 582, 584]; because Plays are made for their delight: but it does not follow, that they are always pleased with good plays; or that the plays which please them, are always good. The Humour of the people is now for Comedy; therefore, in hope to please them, I write Comedies rather than serious Plays; and, so far, their taste prescribes to me. But it does not follow from that reason, that Comedy is to be preferred before Tragedy, in its own nature. For that which is so, in its own nature, cannot be otherwise; as a man cannot but be a rational creature: but the opinion of the people may alter; and in another Age, or perhaps in this, serious Plays may be set up above Comedies. This I think a sufficient answer. If it be not, he has provided me of [_with_] an excuse. It seems, in his wisdom, he foresaw my weakness; and has found out this expedient for me, _That it is not necessary for Poets to study strict Reason; since they are so used to a greater latitude than is allowed by that severe inquisition; that they must infringe their own jurisdiction to profess themselves obliged to argue well_. I am obliged to him, for discovering to me this back door; but I am not yet resolved on my retreat. For I am of opinion, that they cannot be good Poets, who are not accustomed to argue well. False Reasonings and Colours of Speech are the certain marks of one who does not understand the Stage. For Moral Truth is the Mistress of the Poet as much as of the Philosopher. Poesy must _resemble_ Natural Truth; but it must _be_ Ethical. Indeed the Poet dresses Truth, and adorns Nature; but does not alter them. _Ficta voluptatis causa sint proxima veris_. Therefore that is not the best Poesy which resembles notions of _things, which are not_, to _things which are_: though the Fancy may be great, and the Words flowing; yet the Soul is but half satisfied, when there is not Truth in the foundation [p. 560]. This is that which makes VIRGIL [to] be preferred before the rest of poets. In Variety of Fancy, and Sweetness of Expression, you see OVID far above him; for VIRGIL rejected many of those things which OVID wrote. "A great Wit's great work, is to refuse," as my worthy friend, Sir JOHN BIRKENHEAD has ingeniously expressed it. You rarely meet with anything in VIRGIL but Truth; which therefore leaves the strongest impression of Pleasure in the Soul. This I thought myself obliged to say in behalf of Poesy: and to declare (though it be against myself) that when poets do not argue well, the defect is in the Workmen, not in the Art.
