To the moralities, the second important species of drama in the later Middle Ages, the debt of English tragedy is more explicit than to the miracles, but not more essential. It is not more essential, because the moralities were in a way the successors and the substitutes for the miracles and contributed largely to the same effects. They were devoted to a serious purpose and presented tragic situations with a free admixture of comedy, and they continued many of the older traditions of stage performance and undramatic form. They differed from the miracles chiefly in that, like so much of medieval literature, they offered not a direct but a symbolic presentation of life. Instead of the Bible narrative, they presented the strife of vices and virtues; instead of real persons, personified abstractions. This change from individual characters to abstract qualities has usually been regarded as a retrogression by modern students, who deem the study of the motives of individual men and women as essential to the drama. But we have lately been reminded that on the stage it makes little difference whether an actor is called William or Everyman; and the attempt at the symbolization of life offered an opportunity for freedom of invention and freshness of emotional effect that in the miracles had been smothered by the stereotyped repetition of the Bible narrative. The temptation and suffering of the good, the temporary triumph of the evil, and the punishment that overtakes even the mighty were themes which the miracle had confused with many others. The morality gave them dramatic isolation and emphasis. Moreover, in substituting for a translation of the Bible narrative the symbolization of life as a conflict between folly and wisdom, or the vices and virtues, or the body and the soul, the moralities gave importance to one of the most essential elements in tragedy, that of moral strife. The world is a battlefield, the soul is beleaguered, the play is a conflict; and with this element of conflict there arises the opportunity for dramatic structure. If the story is of strife, there is likely to be a moment when the victory hangs in the balance; a reversal of fortune is implied; there is a chance for a rise and fall, a definite beginning, middle, and end. The moral conflict, moreover, encourages a study of human motive, of cause and effect in human action. In some of these plays, as "The Pride of Life," "Everyman," "The Nice Wanton," the consequences of evil are clearly traced, and the action is representative not only of the conflict of good and evil in the universe, but of the battle of will in the individual. Evidently such plays are near relations of tragedy. They at least made plain to their successors the importance of the conflict of good and evil as a dramatic theme. Their text, the wages of sin are death, has continued to be an essential part of the conception of tragedy.
