This definition has had ample recognition in practice and in popular opinion, as in the sixteenth-century idea of a tragedy as a play involving deaths, and in the present common conception of tragedy as requiring an unhappy ending. These uncritical opinions, however, introduce amendments that are not quite corollaries. The happy ending has never been completely excluded. Aristotle, while pronouncing in favor of the unhappy ending as best suited to producing tragic effect, recognized the possibility and popularity of a conclusion that limited punishment to the vicious. In modern times the salvation of the virtuous in tragedy has had warm defenders, including Racine and Dr. Johnson; and the essentiality of either an unhappy ending or of deaths has been generally denied. Evidently either is a natural but not inevitable accompaniment of suffering and disaster. A tragedy may permit of relief or even recovery for the good, or it may minimize the external and physical elements of suffering; but its action must be largely unhappy though its end is not, and destructive even if it does not lead to deaths. Our working definition, however, does not attempt to indicate the qualities necessary to excellence in tragedy or to particularize in respect to the treatment of the action. It offers no distinction, where recent critics have been careful to make one, between tragedy and what we to-day call melodrama.[1] The relation between the two is similar to that between comedy and farce. Melodrama is more sensational, less serious; it attains its effects by spectacles, machines, externals, while tragedy deals with character and motive; it reaches its conclusions through accidents and surprises, while tragedy seeks to show the cause of every effect. But the distinction is general and relative rather than specific and absolute. The use of witches to foretell actions and characters would of itself be a melodramatic device, and so it is in Middleton's "Witch," but not in "Macbeth." Congreve's "Mourning Bride" is a melodrama, judged by our standards at present, but for many years it was considered one of the great tragedies in the language. A stage presentation, in fact, almost presupposes external, spectacular, and sensational effects, which must vary according to the theatrical conditions and the taste of the day, as well as in response to the artistic purpose and treatment. The distinction between melodrama and tragedy, in short, is hardly more than between bad tragedy and good, or between a lower and a higher type. So far as a separation of the two has been made, it has been the result of centuries of experience. It cannot readily be fixed by rule or definition; it requires historical treatment.
