King Lear, after having disowned Cordelia tells Burgundy that, “her price has fallen”, (Act 1. Sc.1. Line 225) not only objectifying her but also warning his other daughters that if they follow suit, the same fate will befall them as well--encouraging the difference between the private and public lives of his daughters to exist, and again not recognizing the truth in the situation.
While this is occurring, Edmund plots against his half-brother Edwardout of greed and jealousy, similar to Goneril and Regan.
“Legitimate Edgar, I must have your land,”(Act 1. Sc.2. Line 16). He states his devious plans against Edgar, his half-brother, in his monologue beginning in act 2.Wishing to be the legitimate son of Gloucester instead of the base bastard of the family, he schemes against his brother by forging a letter, wishing to demonize him in the eyes of his father. Thus, Gloucester will look kindly on Edmund and make him his heir.
“And my invention thrive, Edmund the base
Shall [top] th’ legitimate. I grow, I prosper.
Now, gods, stand up for bastards!” (Act.1. Sc.1. Line 21-23).
Edmund plans to “top” Edgar, portraying himself as a dominator rather than a person with a gentle manner.
In public however, while with his father, Edmund pretends to hide the letter and tells his father that
From my brother that I have not all o’eeread; and
For so much as I have perused, I find it not fit for
Your o’oerlooking.” (Act.1. Sc.2. Lines 38-41).
Edmund feigns timidity and consideration on behalf of his father as well as his brother in public, in contrast to his desire for dominance and power in private.
After reading the forged letter, Gloucester exclaims: “O Villain, Villain!” (Act 1.Sc. 2. Line 79), referring to his son Edgar who believes wants his death. Similar to Lear, Gloucester is manipulated by his greedy child to detest his genuine offspring; Edgar. The blindness on the part of Gloucester and Lear (failure to see through public falsehood) makes them vulnerable to deception. They cannot distinguish between the false and the truth, and see the difference between private person and public person.
When alone, Edmund calls himself “rough and lecherous” (Act 1. Sc. 2. Line 138) however as he meets his brother Edgar, he says “Brother, I advise you to the best”. (Act 1.Sc. 2. Line 180), pretending to care for him he warns him against his father’s wrath which might hurt him. Edgar’s trust in his brother, (blindness in the face of evil), leads him to be oblivious to the difference in Edmund’s private intentions and his public actions/words.
