From the beginning of the play Edgar is surrounded with how true his words are, starting with the letter in his handwriting talking about overthrowing his father. After he flees Gloucester’s castle in Act II scene i, he is seen shortly after in scene iii. This is the last scene before Edgar becomes crazy and speaking like a madman. In Edgar's soliloquy, however he provides evidence that leads one to question the meaning of his madman ramblings. He says“ No port is free; no place that guard and most unusual vigilance does not attend my taking.” (II,iii). This shows Edgar’s feelings of paranoia toward the world around him. He feels unable to trust anyone because he is a wanted man, and he cannot run far away because his father closed the ports. Therefore when in the presence of Lear he pretends to be mad because he knows he cannot trust anyone.
Edgar’s facade meets it’s ultimate test when Gloucester finds Edgar and Lear’s party in the hovel and he finds himself unable to recognize his own son. Edgar, however recognizes him and at this point of the scene he restrains his speech to minimal words and random outbursts. Earlier in the act Edgar spoke lengthy speeches about random madman speech and then when Gloucester appears he finds himself unable to say anything more than a few words. When Edgar does this he acts as if he is trying to protect his identity from Gloucester. This difference in his sentences may be him trying to speak as little as possible to hope his father does not recognize his voice.
Even when he is blind Gloucester still remain ignorant to the sound of his son’s voice, however he does realize that the man he perceives as a poor Tom is capable of speaking very rationally for a madman. Edgar’s rational speech is the result of him letting his guard down to his blind father. He knows his father will not be able to recognize him because he is blind, and he removes his madman facade. The removal of this facade also occurs when Edgar is alone on stage, revealing that his internal thoughts are not the ramblings of a madman, but instead his rational mind buried beneath the facade he created to hide his identity.
