In the Characters there are four points to aim at. First and foremost, that they shall be good. There will be an element of character in the play, if (as has been observed) what a personage says or does reveals a certain moral purpose; and a good element of character, if the purpose so revealed is good. Such goodness is possible in every type of personage, even in a woman or a slave, though the one is perhaps an inferior, and the other a wholly worthless being. The second point is to make them appropriate. The Character before us may be, say, manly; but it is not appropriate in a female Character to be manly, or clever. The third is to make them like the reality, which is not the same as their being good and appropriate, in our sense of the term. The fourth is to make them consistent and the same throughout; even if inconsistency be part of the man before one for imitation as presenting that form of character, he should still be consistently inconsistent. We have an instance of baseness of character, not required for the story, in the Menelaus in Orestes; of the incongruous and unbefitting in the lamentation of Ulysses in Scylla, and in the (clever) speech of Melanippe; and of inconsistency in Iphigenia at Aulis, where Iphigenia the suppliant is utterly unlike the later Iphigenia. The right thing, however, is in the Characters just as in the incidents of the play to endeavour always after the necessary or the probable; so that whenever such-and-such a personage says or does such-and-such a thing, it shall be the probable or necessary outcome of his character; and whenever this incident follows on that, it shall be either the necessary or the probable consequence of it. From this one sees (to digress for a moment) that the Denouement also should arise out of the plot itself, arid not depend on a stage-artifice, as in Medea, or in the story of the (arrested) departure of the Greeks in the Iliad. The artifice must be reserved for matters outside the play—for past events beyond human knowledge, or events yet to come, which require to be foretold or announced; since it is the privilege of the Gods to know everything. There should be nothing improbable among the actual incidents. If it be unavoidable, however, it should be outside the tragedy, like the improbability in the Oedipus of Sophocles. But to return to the Characters. As Tragedy is an imitation of personages better than the ordinary man, we in our way should follow the example of good portrait-painters, who reproduce the distinctive features of a man, and at the same time, without losing the likeness, make him handsomer than he is. The poet in like manner, in portraying men quick or slow to anger, or with similar infirmities of character, must know how to represent them as such, and at the same time as good men, as Agathon and Homer have represented Achilles.
All these rules one must keep in mind throughout, and further, those also for such points of stage-effect as directly depend on the art of the poet, since in these too one may often make mistakes. Enough, however, has been said on the subject in one of our published writings.
