"Even in a lively oral narration, it is not unusual to introduce persons in conversation with each other, and to give a corresponding variety to the tone and the expression. But the gaps, which these conversations leave in the story, the narrator fills up in his own name with a description of the accompanying circumstances, and other particulars. The dramatic poet must renounce all such expedients; but for this he is richly recompensed in the following invention. He requires each of the characters in his story to be personated by a living individual; that this individual should, in sex, age, and figure, meet as near as may be the prevalent conceptions of his fictitious original, nay, assume his entire personality; that every speech should be delivered in a suitable tone of voice, and accompanied by appropriate action and gesture; and that those external circumstances should be added which are necessary to give the hearers a clear idea of what is going forward. Moreover, these representatives of the creatures of his imagination must appear in the costume belonging to their assumed rank, and to their age and country; partly for the sake of greater resemblance, and partly because, even in dress, there is something characteristic. Lastly, he must see them placed in a locality which, in some degree, resembles that where, according to his fable, the action took place, because this also contributes to the resemblance: he places them, _i.e._, on a scene. All this brings us to the idea of the theatre. It is evident that the very form of dramatic poetry, that is, the exhibition of an action by dialogue without the aid of narrative, implies the theatre as its necessary complement." "The invention of dramatic art, and of the theatre, seems a very obvious and natural one. Man has a great disposition to mimicry; when he enters vividly into the situation, sentiments, and passions of others, he involuntarily puts on a resemblance to them in his gestures. Children are perpetually going out of themselves; it is one of their chief amusements to represent those grown people whom they have had an opportunity of observing, or whatever strikes their fancy; and with the happy pliancy of their imagination, they can exhibit all the characteristics of any dignity they may choose to assume, be it that of a father, a schoolmaster, or a king." In his book, "Imagination and Dramatic Instinct," S. S. Curry says:-- "Since dramatic instinct is so important, the question naturally arises respecting the use of dialogues for its education. There are those who think that all histrionic art is useless; that it is even deleterious to character to assume a part.
