Your lieutenant, Cassio. Good my lord,
If I have any grace or power to move you,
His present reconciliation take;
For if he be not one that truly loves you,
That errs in ignorance and not in cunning,
I have no judgment in an honest face.
– William Shakespeare
Othello, Act 3, Scene 3. Desdemona pleads to Othello on Cassio’s behalf, calling him "your lieutenant, Cassio" and "honest." Desdemona is trying to manipulate her husband into reinstating Cassio back. There is irony in Desdemona’s words "I have no judgment in an honest face." While she claims to be able to read honesty in a person’s face, she has failed to see the dishonesty in Iago’s. As Desdemona attempts to repair Cassio and Othello’s friendship by asking if Cassio can come over for dinner, she is innocently and unwittingly playing into Iago’s hands.
