Now the three unities may be defended on an entirely legitimate ground--on the ground namely that they make for concentration, a prime virtue in the drama; but the grounds on which they were actually imposed on the drama, especially in connection with the Quarrel of the Cid, illustrate the corruption of another main classical doctrine, that of probability or verisimilitude. In his dealings with probability as in his dealings with imitation, the neo-classical formalist did not allow sufficiently for the element of illusion. What he required from the drama in the name of probability was not the “illusion of a higher reality,” but strict logic or even literal deception. He was not capable of a poetic faith, not willing to suspend his disbelief on passing from the world of ordinary fact to the world of artistic creation. Goethe was thinking especially of the neo-classical French when he said: “As for the French, they will always be arrested by their reason. They do not recognize that the imagination has its own laws which are and always must be problematic for the reason.” It was also largely under French influence that the doctrine of decorum, which touches probability at many points, was turned aside from its true meaning. Decorum is in a way the peculiar doctrine of the classicist, is in Milton’s phrase “the grand masterpiece to observe.” The doctrines of the universal and the imitation of the universal go deeper indeed than decorum, so much deeper that they are shared by classicism with religion. The man who aspires to live religiously must no less than the humanist look to some model set above his ordinary self and imitate it. But though the classicist at his best meditates, he does not, like the seeker after religious perfection, see in meditation an end in itself but rather a support for the mediatory virtues, the virtues of the man who would live to the best advantage in this world rather than renounce it; and these virtues may be said to be summed up in decorum. For the best type of Greek humanist, a Sophocles let us say, decorum was a vital and immediate thing. But there enters into decorum even from the time of the Alexandrian Greeks, and still more into French neo-classical decorum, a marked element of artificiality. The all-roundness and fine symmetry, the poise and dignity that come from working within the bounds of the human law, were taken to be the privilege not of man in general but of a special social class. Take for instance verbal decorum: the French neo-classicists assumed that if the speech of poetry is to be noble and highly serious it must coincide with the speech of the aristocracy. As Nisard puts it, they confused nobility of language with the language of the nobility. Decorum was thus more or less merged with etiquette, so that the standards of the stage and of literature in general came to coincide, as Rousseau complains, with those of the drawing-room. More
