“I know my price, I am worth no worse a place:
  But he; as loving his own pride and purposes,
  Evades them”

The lines are spoken by Iago to Roderigo in act one scene one in order to convince Roderigo that he hates Othello. The theme of isolation appears in this quote through the idea of being undervalued and overlooked by others. Iago feels isolated because he believes that he deserves a higher rank and greater recognition from Othello, but his abilities and contributions are being ignored or dismissed. He laments that Othello is more focused on his own pride and goals, which leaves Iago feeling isolated and undervalued. The quote also suggests that Iago is willing to manipulate others to achieve his own objectives, which further reinforces his sense of isolation from those around him. Overall, the quote highlights the negative consequences of feeling undervalued and the potential for isolation and resentment that can result from it.

“tis the curse of service,
 Preferment goes by letter and affection,”

The theme of isolation appears in this quote through the idea of being at the mercy of external forces that are beyond one’s control. Iago feels isolated because he believes that his abilities and hard work are not enough to earn him the “preferment” and recognition he desires. Instead, he feels that favouritism and personal connections play a larger role in determining who gets ahead in life, leaving him feeling isolated and helpless. The quote suggests that Iago is frustrated with the limitations of his position and the unfairness of the system, which reinforces his sense of isolation from those in power. Overall, the quote highlights the negative consequences of feeling powerless and the potential for isolation and bitterness that can result from it. The idea uttered by Iago further suggests how the sense of isolation is caused in the play through one’s profession as well.

“I follow him to serve my turn upon him:”

The theme of isolation appears in this quote through the idea of using others for personal gain. Iago feels isolated because he believes that he must resort to manipulation and deceit to achieve his goals, rather than relying on his own abilities and merits. He sees Othello as a means to an end, rather than a person deserving of respect or loyalty, which reinforces his sense of isolation from others. The quote suggests that Iago is willing to exploit Othello’s trust and vulnerability to further his own ambitions, which deepens his isolation from those around him. Overall, the quote highlights the negative consequences of using others for selfish purposes and the potential for isolation and moral decay that can result from it.

Apart from that, Iago reveals his intention to manipulate and deceive Othello for his own benefit. By doing so, Iago isolates Othello by undermining his trust in others and creating a sense of paranoia and suspicion.

“Nay, but he prated,
And spoke such scurvy and provoking terms
Against your honour…”

Act I, Scene 2 opens with Iago informing Othello that Roderigo has betrayed his honour. Iago deserts Roderigo as soon as he decides it is appropriate so he can exact revenge. Iago also uses the fact that others are scheming against Othello to make him feel isolated so that he may easily separate Othello from others around him.

Good gentlemen, let me have leave to speak:
‘Tis proper I obey him, but not now.
Perchance, Iago, I will ne’er go home.

In Act V, Scene II of Shakespeare’s “Othello,” Emilia’s lines illustrate Iago’s isolation as a result of his manipulative actions and the revelation of his deceit.

Exposure of Deception: Emilia’s refusal to obey Iago’s authority at this critical moment reflects a shift in her perception of him. Her decision to speak out contradicts her usual subservience, signalling a rupture in her loyalty. This sudden change is due to her realisation of Iago’s manipulative and destructive deeds. This exposure of Iago’s deception sets him apart from the characters who were previously under his sway.
Loss of Allies: Throughout the play, Iago manages to manipulate and deceive others, effectively isolating them emotionally and mentally. However, as his schemes unravel, allies such as Emilia become aware of his true nature. In Emilia’s lines, her rejection of Iago’s authority symbolises her detachment from him, marking a loss of his support and control.
Betrayal and Abandonment: Emilia’s declaration that she might “ne’er go home” with Iago hints at a sense of betrayal and abandonment. The phrase suggests that she no longer wishes to be associated with Iago, perhaps due to her realisation of his role in orchestrating Desdemona’s tragic fate. This sense of abandonment highlights Iago’s isolation, as his closest allies turn away from him.
Reckoning with Truth: As the truth behind Iago’s manipulation emerges, characters like Emilia grapple with the consequences of their actions. The revelation of Iago’s deceit causes a rupture in the relationships he cultivated, further isolating him emotionally and mentally.

In summary, Emilia’s lines in Act V, Scene II of “Othello” symbolise Iago’s isolation resulting from the exposure of his manipulation and deceit. His allies, once under his influence, turn away from him as they recognise his true nature. This isolation reflects the unravelling of Iago’s schemes and his descent into a state of psychological and emotional separation from those he manipulated.

Welcome, mistress.
Let it not gall your patience, good Iago,
That I extend my manners; ’tis my breeding
That gives me this bold show of courtesy.
[Kissing her]

In Act 2, Scene 1, Cassio’s act of kissing Emilia, Iago’s wife, contributes to Iago’s sense of isolation primarily because it highlights the contrast between Cassio’s seemingly genuine and open behaviour and Iago’s manipulative and secretive nature.

Contrasting Characters: Cassio is portrayed as an honourable and trustworthy character, openly displaying affection towards Emilia. In contrast, Iago is a master manipulator who conceals his true intentions and feelings from others. This contrast in character traits and behaviours can make Iago feel isolated because he perceives himself as an outsider in a world of trust and genuine emotions. From a different perspective, Cassio’s bold and lustful nature stands in stark contrast to Iago’s calculated and manipulative demeanor. Cassio’s willingness to openly express his desires and affections may make Iago feel even more isolated because he cannot relate to or openly express his own emotions and desires.

Jealousy and Insecurity: Iago’s isolation is intensified by his jealousy and insecurity. Seeing Cassio’s open interaction with Emilia may make Iago feel inadequate and threatened. He may worry that others, including his wife, Emilia, trust Cassio more than they trust him. This jealousy and insecurity contribute to his sense of isolation because he cannot genuinely connect with those around him.

Isolation by Choice: Iago’s isolation is, to a large extent, self-imposed. His manipulative schemes and deceitful nature isolate him from forming true bonds with others. He cannot confide in anyone or seek genuine companionship because he is constantly deceiving and manipulating those around him. This self-imposed isolation is a central aspect of Iago’s character and is further highlighted by Cassio’s open actions.

In essence, Cassio’s kiss to Emilia symbolises the divide between his open, trustworthy character and Iago’s secretive, manipulative nature. This contrast intensifies Iago’s sense of isolation as he struggles to connect with those around him genuinely.
