Whether Shakespeare knew the unities, and rejected them by design, or deviated from them by happy ignorance, it is, I think, impossible to decide, and useless to enquire. We may reasonably suppose that, when he rose to notice, he did not want the counsels and admonitions of scholars and criticks, and that he at last deliberately persisted in a practice, which he might have begun by chance. As nothing is essential to the fable but unity of action, and as the unities of time and place arise evidently from false assumptions, and, by circumscribing the extent of the drama, lessen its variety, I cannot think it much to be lamented that they were not known by him, or not observed: nor, if such another poet could arise, should I very vehemently reproach him, that his first act passed at Venice, and his next in Cyprus. Such violations of rules merely positive become the comprehensive genius of Shakespeare, and such censures are suitable to the minute and slender criticism of Voltaire: Non usque adeo permiscuit imis Longus summa dies, ut non, si voce Metelli Serventur leges, malint a Cæsare tolli. Yet when I speak thus slightly of dramatick rules, I cannot but recollect how much wit and learning may be produced against me; before such authorities I am afraid to stand, not that I think the present question one of those that are to be decided by mere authority, but because it is to be suspected that these precepts have not been so easily received but for better reasons than I have yet been able to find. The result of my enquiries, in which it would be ludicrous to boast of impartiality, is that the unities of time and place are not essential to a just drama, that though they may sometimes conduce to pleasure, they are always to be sacrificed to the nobler beauties of variety and instruction; and that a play, written with nice observation of critical rules, is to be contemplated as an elaborate curiosity, as the product of superfluous and ostentatious art, by which is shewn, rather what is possible, than what is necessary. He that, without diminution of any other excellence, shall preserve all the unities unbroken, deserves the like applause with the architect who shall display all the orders of architecture in a citadel, without any deduction from its strength; but the principal beauty of a citadel is to exclude the enemy; and the greatest graces of a play are to copy nature, and instruct life. Perhaps what I have here not dogmatically but deliberately written, may recall the principles of the drama to a new examination. I am almost frighted at my own temerity; and when I estimate the fame and the strength of those that maintain the contrary opinion, am ready to sink down in reverential silence; as Æneas withdrew from the defence of Troy, when he saw Neptune shaking the wall, and Juno heading the besiegers.
