Read it through once

-- * The dramatic monologue differs from a soliloquy in this: while there is but one speaker, the presence of a silent second person is supposed, to whom the arguments of the speaker are addressed. Perhaps such a situation may be termed a novelty of invention in our Poet. It is obvious that the dramatic monologue gains over the soliloquy in that it allows the artist greater room in which to work out his conception of character. We cannot gaze long at a solitary figure on a canvas, however powerfully treated, without feeling some need of relief. In the same way a soliloquy (comp. the great soliloquies of Shakespeare) cannot be protracted to any great length without wearying the listener. The thoughts of a man in self-communion are apt to run in a certain circle, and to assume a monotony. The introduction of a second person acting powerfully upon the speaker throughout, draws the latter forth into a more complete and varied expression of his mind. The silent person in the background, who may be all the time master of the situation, supplies a powerful stimulus to the imagination of the reader.--Rev. Prof. E. Johnson’s “Paper on ‘Bishop Blougram’s Apology’” (‘Browning Soc. Papers’, Pt. III., p. 279). --
