"This hand gives itself away very freely. In the old days, people used to give their hearts to each other when they joined their hands in marriage. But these days, people give each other their hands without their hearts" [Act 3 Scene 4 Pg175] This scene is an Outward/External conflict. In this scene Othello yells at his wife for cheating on him and accusing her for engaging in sexual activities with other men without any hard proof. This is an Outward/External conflict because it is a struggle between a character(Othello) and another character(Desdemona) which drives the dramatic action of the plot. In this case, Othello yells at his wife and since she doesn't know how to answer, not expecting her husband to be like this towards her, he is further convinced that she is cheating. This leads to Othello hating her even more and Desdemona just being confused that her beloved husband is angry at her.
"So please listen to me... Watch your wife. Watch how she is with Cassio. Just watch—don’t be either completely suspicious or completely trustful. I wouldn’t want to see you taken advantage of because you’re such an open and trusting guy. I know the people of Venice well. They let God see things they wouldn’t show their husbands. They don’t avoid doing things that are wrong, they just try not to get caught." [Act 3 Scene 3 Pg145] This is an Outward/External conflict. In this scene Iago tells Othello of his "suspicions" and causes Othello to become nervous thus allowing for Iago's master plan to commence. This is an outward conflict because it is a conflict between one character and another that drives the dramatic action of a text. In this scene one character, Iago, makes another character, Othello, believe that his wife is cheating on him with his leutenant. He uses Othello's wife's natural kindness and sympathy along with Othello's trust in order to convince Othello of something that is entirely not true.
"(to himself) Why did I ever get married? I’m sure this good and honest man sees and knows more, much more, than he’s telling me." [Act 3 Scene 3 Pg149] This is an Inward/Internal Conflict. This scene occurs right after Iago tells Othello his "suspicions" and leaves. After this Othello is left wondering if his wife could even have cheated, and why he even married. Due to Othello's trusting nature he instantly believed his friends words and began to get upset. This is an Inward/Internal conflict because it is a psychological struggle within the mind of a literary or dramatic character, the resolution of which creates the plots suspense. One character (Iago) makes Othello think that his wife is cheating, and he will not let go of this thought until he gets revenge or proof of her faithfulness. Othello being the not so intelligent person that he is doesn't even talk to his wife before accusing and hitting her, someone he loved with all his heart.
