Literally soliloquy means talking to himself aloud when a person is alone or is supposed to be alone. In a play it means the talking on the part of the character regardless of the presence of hearers. As in the case of Faustus’ first soliloquy, it nicely sums up his life and growth of his ideas that took place before the actions that are going to occur on the stage. Sometimes a soliloquy enables us to understand the motives of a character. And one of the most significant uses of the soliloquy is to reveal a deep experience or a typical state of mind with all its waverings and inner conflict. Sometimes a soliloquy may reveal the moral underlying a play as we find in the case of the soliloquy of Shakespeare’s Othello and that of Marlowe’s Faustus in the last scene.
