Act 3, Scene 3- Big question 2 improvements

How do ideas about difference and otherness help Iago's manipulation of Othello in this scene?

During an extended prose where Desdemona is heard to be trying to persuade Othello for Cassio's position as his lieutenant back, she states that Cassio was the man who 'came a-wooing' for her love along side him. This immediately plants a seed of doubt in Othello's mind after many sly comments Iago has expressed himself. It makes him feel betrayed that she would not honour his decision and stand by him as his loving wife. His self-esteem is knocked as he now believes that he would not have won Desdemona over if it wasn't for Cassio and that she may have feelings for him too. By having this slight doubt in the back of his mind, Othello will now confide in Iago's opinions and become more dependant on him for decisions he must make. Therefore, Iago is now able to use his words of 'wisdom' to manipulate Othello and influence him in to persuading Othello that the wrong decision could be right.
 Iago also uses Othello and Desdemona's differences to make him doubt their marriage and believe their love is just an experiment or a passing phase. He is reminded about Desdemona's 'clime, complexion, and degree' being very different from his own. Iago makes Othello believe that they are complete opposites and that she will soon be looking for a man more like herself to pleasure her. Iago uses Othello's otherness to an advantage, making him doubt himself and believe he cannot make his love happy. After becoming so doubtful, Othello will become paranoid and start to overly analyse what others say to or about him. Othello is constantly referred to as the 'Moor' also making him insecure and doubt his image as well as his place in society. Being a completely different race to Desdemona reveals many problems and puts unnecessary pressure on their relationship-more than any other. They are judged for this and Iago can use this to push Othello in to believing that it is a bigger issue than it really is.
After the seed of doubt has been planted in to Othello's mind, he now starts to think himself of reasons he and Desdemona should not be together. Iago gets Othello to address the issues with himself and Desdemona's love through his own eyes and not just others. 'Haply for I am black, And have not those soft parts of conversation(...)I am declined in to the valve of years'. For the first time in the play he calls himself what everybody else sees him as. Calling himself by his skin colour makes him objectify himself. Iago has made him feel nothing more than the colour of his skin and not as a human. He acknowledges that he is not like others and states that he lacks in manners and is older than Desdemona. His masculine pride is wounded and Iago has succeeded in manipulating Othello to the stage where he starts to dehumanise himself. With his pride wounded, it makes it harder for Othello to deny that Desdemona may prefer to be with Cassio and that she is only with Othello out of pity.

How do ideas about difference and otherness help Iago's manipulation of Othello in this scene?
Desdemona tries to help Cassio and discusses with Othello the reasons he should stay as his lieutenant. She states that Cassio was the man who 'came a-wooing' for her love along side him. This possibly plants a seed of doubt in Othello's mind after many sly comments Iago has expressed himself. It makes him feel betrayed that she would not honour his decision and stand by him as his loving wife. His self-esteem is knocked as he may now believe that he would not have won Desdemona over if it wasn't for Cassio and that she may have feelings for him too. By having this slight doubt in the back of his mind, Othello will now confide in Iago's opinions and become more dependent on him for decisions he must make.

After the seed of doubt has been planted in to Othello's mind, he may arguably now start to think himself of reasons he and Desdemona should not be together.

'Haply for I am black, And have not those soft parts of conversation(...)I am declined in to the valve of years'. For the first time in the play he calls himself what everybody else sees him as.
