In the fourth scene, Cordelia, talking with a physician, tells him that Lear has been seen, that he is quite mad, wearing on his head a wreath of various weeds, that he is roaming about and that she has sent soldiers in search of him, adding that she desires all secret remedies to spring with her tears, and the like. She is informed that the forces of the Dukes are approaching, but she is concerned only about her father and departs. The fifth scene of the fourth act lies in Gloucester's castle. Regan is talking with Oswald, Goneril's steward, who is carrying a letter from Goneril to Edmund, and she announces to him that she also loves Edmund and that, being a widow, it is better for her to marry him than for Goneril to do so, and she begs him to persuade her sister of this. Further she tells him that it was very unreasonable to blind Gloucester and yet leave him alive, and therefore advises Oswald, should he meet Gloucester, to kill him, promising him a great reward if he does this. In the sixth scene, Gloucester again appears with his still unrecognized son Edgar, who (now in the guise of a peasant) pretends to lead his father to the cliff. Gloucester is walking along on level land but Edgar persuades him that they are with difficulty ascending a steep hill. Gloucester believes this. Edgar tells his father that the noise of the sea is heard; Gloucester believes this also. Edgar stops on a level place and persuades his father that he has ascended the cliff and that in front of him lies a dreadful abyss, and leaves him alone. Gloucester, addressing the gods, says that he shakes off his affliction as he can bear it no longer, and that he does not condemn them--the gods. Having said this, he leaps on the level ground and falls, imagining that he has jumped off the cliff. On this occasion, Edgar, soliloquizing, gives vent to a yet more entangled utterance: "I know not how conceit may rob The treasury of life when life itself Yields to the theft; had he been where he thought, By this had thought been past."
