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 than anything else this narrowing of decorum marks the decline from the classic to the pseudo-classic, from form to formalism.
While condemning pseudo-decorum one should remember that even a Greek would have seen something paradoxical in a poem like Goethe’s “Hermann und Dorothea” and its attempt to invest with epic grandeur the affairs of villagers and peasants. After all, dignity and elevation and especially the opportunity for important action, which is the point on which the classicist puts prime emphasis, are normally though not invariably associated with a high rather than with a mean social estate. In general one should insist that the decorum worked out under French auspices was far from being merely artificial. The French gentleman (honnête homme) of the seventeenth century often showed a moderation and freedom from over-emphasis, an exquisite tact and urbanity that did not fall too far short of his immediate model, Horace, and related him to the all-round man of the Greeks (καλὸς κἀγαθός). To be sure an ascetic Christian like Pascal sees in decorum a disguise of one’s ordinary self rather than a real curb upon it, and feels that the gap is not sufficiently wide between even the best type of the man of the world and the mere worldling. One needs, however, to be very austere to disdain the art of living that has been fostered by decorum from the Greeks down. Something of this art of living survives even in a Chesterfield, who falls far short of the best type of French gentleman and reminds one very remotely indeed of a Pericles. Chesterfield’s half-jesting definition of decorum as the art of combining the useful appearances of virtue with the solid satisfactions of vice points the way to its ultimate corruption. Talleyrand, who marks perhaps this last stage, was defined by Napoleon as “a silk stocking filled with mud.” In some of its late exemplars decorum had actually become, as Rousseau complains, the “mask of hypocrisy” and the “varnish of vice.”
One should not however, like Rousseau and the romanticists, judge of decorum by what it degenerated into. Every doctrine of genuine worth is disciplinary and men in the mass do not desire discipline. “Most men,” says Aristotle, “would rather live in a disorderly than in a sober manner.” But most men do not admit any such preference—that would be crude and inartistic. They incline rather to substitute for the reality of discipline some art of going through the motions. Every great doctrine is thus in constant peril of passing over into some hollow semblance or even, it may be, into some mere caricature of itself. When one wishes therefore to determine the nature of decorum one should think of a Milton, let us say, and not of a Talleyrand or even of a Chesterfield.
Milton imitated the models, like any other neo-classicist, but his imitation was not, in Joubert’s phrase, that of one book by another book, but of one soul by another soul. His decorum is therefore imaginative; and it is the privilege of the imagination to give the sense of spaciousness and infinitude. On the other hand, the unimaginative way in which many of the neo-classicists held their main tenets—nature, imitation, probability, decorum—narrowed unduly the scope of the human spirit and appeared to close the gates of the future. “Art and diligence have now done their best,” says Dr. Johnson of the versification of Pope, “and what shall be added will be the effort of tedious toil and needless curiosity.” Nothing is more perilous than thus to seem to confine man in some pinfold; there is something in him that refuses to acquiesce in any position as final; he is in Nietzsche’s phrase the being who must always surpass himself. The attempt to oppose external and mechanical barriers to the freedom of the spirit will create in the long run an atmosphere of stuffiness and smugness, and nothing is more intolerable than smugness. Men were guillotined in the French Revolution, as Bagehot suggests, simply because either they or their ancestors had been smug. Inert acceptance of tradition and routine will be met sooner or later by the cry of Faust: Hinaus ins Freie!
Before considering the value of the method chosen by Rousseau and the romanticists for breaking up the “tiresome old heavens” and escaping from smugness and stuffiness, one should note that the lack of originality and genius which they lamented in the eighteenth century—especially in that part of it known as the Enlightenment—was not due entirely to pseudo-classic formalism. At least two other main currents entered into the Enlightenment: first the empirical and utilitarian current that goes back to Francis Bacon, and some would say to Roger Bacon; and secondly the rationalistic current that goes back to Descartes. English empiricism gained international vogue in the philosophy of Locke, and Locke denies any supersensuous element in human nature to which one may have access with the aid of the imagination or in any
