Othello 4.2-3

Othello has calmed down from the previous scene and is now questioning Emilia about Desdemona and Cassio's relationship. Emilia denies anything but it only goes to feed Othello's jealousy and suspicion. Emilia goes to call Desdemona and when she gets there, she immediately becomes obedient, even kneeling, to Othello. Othello questions her too and starts to become more agitated until he once again becomes a mad person like the end of scene 1. Desdemona is heartbroken and tells Emilia to call Iago as he is someone who is close to Othello and could tell her why he is acting the way he did. Iago, after being indirectly abused by his own wife, dismisses Othello's attitude as stress built up after being told to return home. Desdemona is reassured and still retains her unyielding love for Othello. Roderigo soon enters and we learn that he was being swindled by Iago in the belief that he was making advances on Desdemona. Roderigo is upset until Iago provides him another lie and plan which involves killing Cassio at night. Scene 3 mainly consists of Desdemona and Emilia having a conversation about the nature of men and wives. Emilia is negative and says that men are like stomachs and women, food. On the other hand, Desdemona believes in her love and still has trust in men.

The opposing views of Emilia and Desdemona about marriage display the theme of women evident in Othello. Desdemona asks Emilia if she would commit adultery if she could gain the world, to which Emilia replies with a confident yes. Desdemona is shocked as she herself would never do such a thing. Emilia goes to explain how it is due to husband's faults. Emilia says that the husbands being unfaithful are the reason why women are also unfaithful. For once in the play, women are seen to be rebellious of what men say. Throughout the play, wives such as Desdemona and Emilia are seen to be in a weaker position and made to concede to men's desires. However, Emilia proves that while she yields to men in her actions, she maintains a rebellious view on men in her mind.

How has Desdemona's naivety made her a more faithful and loyal wife?
Desdemona, being young, has an inborn naivety about her society. She will not commit adultery because she has learned that adultery is a horrible act and isn't aware of adultery in the people around her. She also doesn't get jealous or distrustful of Othello when he becomes mad. She simply believes that his work is creating stress or he is feeling ill, never suspecting his mental state for jealousy.
