text: "What," you say, "will it not be seen whose style you are imitating, whose method of reasoning, whose pungent sayings?" I think that sometimes it is impossible for it to be seen who is being imitated, if the copy is a true one; for a true copy stamps its own form upon all the features which it has drawn from what we may call the original, in such a way that they are combined into a unity. Do you not see how many voices there are in a chorus? Yet out of the many only one voice results. In that chorus one voice takes the tenor, another the bass, another the baritone. There are women, too, as well as men, and the flute is mingled with them. In that chorus the voices of the individual singers are hidden; what we hear is the voices of all together. To be sure, I am referring to the chorus which the old-time philosophers knew; in our present-day exhibitions we have a larger number of singers than there used to be spectators in the theatres of old. All the aisles are filled with rows of singers; brass instruments surround the auditorium; the stage resounds with flutes and instruments of every description; and yet from the discordant sounds a harmony is produced.
