lity.'

The Chorus too should be regarded as one of the actors; it should be an
integral part of the whole, and share in the action, in the manner not
of Euripides but of Sophocles. As for the later poets, their choral
songs pertain as little to the subject of the piece as to that of any
other tragedy. They are, therefore, sung as mere interludes, a practice
first begun by Agathon. Yet what difference is there between introducing
such choral interludes, and transferring a speech, or even a whole act,
from one play to another?

It remains to speak of Diction and Thought, the other parts of Tragedy
having been already discussed. Concerning Thought, we may assume what
is said in the Rhetoric, to which inquiry the subject more strictly
belongs. Under Thought is included every effect which has to be produced
by speech, the subdivisions being,--proof and refutation; the excitation
of the feelings, such as pity, fear, anger, and the like; the suggestion
of importance or its opposite. Now, it is evident that the dramatic
incidents must be treated from the same points of view as the dramatic
speeches, when the object is to evoke the sense of pity, fear,
importance, or probability. The only difference is, that the incidents
should speak for themselves without verbal exposition; while the effects
aimed at in speech should be produced by the speaker, and as a result of
the speech. For what were the business of a speaker, if the Thought were
revealed quite apart from what he says?

Next, as regards Diction. One branch of the inquiry treats of the Modes
of Utterance. But this province of knowledge belongs to the art
of Delivery and to the masters of that science. It includes, for
instance,--what is a command, a prayer, a statement, a threat, a
question, an answer, and so forth. To know or not to know these things
involves no serious censure upon the poet's art. For who can admit
the fault imputed to Homer by Protagoras,--that in the words, 'Sing,
goddess, of the wrath,' he gives a command under the idea that he utters
a prayer? For to tell some one to do a thing or not to do it is, he
says, a command. We may, therefore, pass this over as an inquiry that
belongs to another art, not to poetry.
