In his other works he has well enough preserved the unity of action.  He has not, indeed, an intrigue regularly perplexed and regularly unravelled:  he does not endeavour to hide his design only to discover it, for this is seldom the order of real events, and Shakespeare is the poet of nature:  But his plan has commonly what Aristotle requires, a beginning, a middle, and an end; one event is concatenated with another, and the conclusion follows by easy consequence.  There are perhaps some incidents that might be spared, as in other poets there is much talk that only fills up time upon the stage; but the general system makes gradual advances, and the end of the play is the end of expectation.

To the unities of time and place he has shewn no regard; and perhaps a nearer view of the principles on which they stand will diminish their value, and withdraw from them the veneration which, from the time of Corneille, they have very generally received, by discovering that they have given more trouble to the poet, than pleasure to the auditor.

The necessity of observing the unities of time and place arises from the supposed necessity of making the drama credible.  The criticks hold it impossible, that an action of months or years can be possibly believed to pass in three hours; or that the spectator can suppose himself to sit in the theatre, while ambassadors go and return between distant kings while armies are levied and towns besieged, while an exile wanders and returns, or till he whom they saw courting his mistress, shall lament the untimely fall of his son.  The mind revolts from evident falsehood, and fiction loses its force when it departs from the resemblance of reality.

From the narrow limitation of time necessarily arises the contraction of place.  The spectator, who knows that he saw the first act at Alexandria, cannot suppose that he sees the next at Rome, at a distance to which not the dragons of Medea could, in so short a time, have transported him; he knows with certainty that he has not changed his place, and he knows that place cannot change itself; that what was a house cannot become a plain; that what was Thebes can never be Persepolis.

Such is the triumphant language with which a critick exults over the misery of an irregular poet, and exults commonly without resistance or reply.  It is time therefore to tell him by the authority of Shakespeare, that he assumes, as an unquestionable principle, a position, which, while his breath is forming it into words, his understanding pronounces to be false.  It is false, that any representation is mistake for reality; that any dramatick fable in its materiality was ever credible, or, for a single moment, was ever credited.
