In Shakespeare's classic tragedy, King Lear, the issue of sight and its relevance to clear vision is a recurring theme. Shakespeare's principal means of portraying this theme is through the characters of Lear and Gloucester. Although Lear can physically see, he is blind in the sense that he lacks insight, understanding, and direction. In contrast, Gloucester becomes physically blind but gains the type of vision that Lear lacks. It is evident from these two characters that clear vision is not derived solely from physical sight. Lear's failure to understand this is the principal cause of his demise, while Gloucester learns to achieve clear vision, and consequently avoids a fate similar to Lear's. Throughout most of King Lear, Lear's vision is clouded by his lack of insight. Since he cannot see into other people's characters, he can never identify them for who they truly are. When Lear is angered by Cordelia, Kent tries to reason with Lear, who is too stubborn to remain open-minded. Lear responds to Kent's opposition with, Out of my sight!, to which Kent responds, See better, Lear, and let me still remain (I.i.160). Here, Lear is saying he never wants to see Kent again, but he could never truly see him for who he was. Kent was only trying to do what was best for Lear, but Lear could not see that. Kent's vision is not clouded, as is Lear's, and he knows that he can remain near Lear as long as he is in disguise. Later, Lear's vision is so superficial that he is easily duped by the physical garments and simple disguise that Kent wears. Lear cannot see who Kent really. He only learns of Kent's noble and honest character just prior to his death, when his vision is cleared. By this time, however, it is too late for an honest relationship to be salvaged. Lear's vision is also marred by his lack of direction in life, and his poor foresight, his inability to predict the consequences of his actions. He cannot look far enough into the future to see the consequences of his actions. This, in addition to his lack of insight into other people, condemns his relationship with his most beloved daughter, Cordelia. When Lear asks his daughters who loves him most, he already thinks that Cordelia has the most love for him. However, when Cordelia says, I love your Majesty/According to my bond, no more nor less (I.i.94-95), Lear cannot see what these words really mean. Goneril and Regan are only putting on an act. They do not truly love Lear as much as they should. When Cordelia says these words, she has seen her sisters' facade, and she does not want to associate her true love with their false love. Lear, however, is fooled by Goneril and Regan into thinking that they love him, while Cordelia does not. Kent, who has sufficient insight, is able to see through the dialogue and knows that Cordelia is the only daughter who actually loves Lear. He tries to convince Lear of this, saying, Answer my life my judgment,/Thy youngest daughter does not love thee least (I.i.153-154). Lear, however, lacks the insight that Kent has. He only sees what is on the surface, and cannot understand the deeper intentions of the daughters' speeches. As his anger grows from the argument, his foresight diminishes as he becomes increasingly rash and narrow minded . When Lear disowns Cordelia, he says, we/Have no such daughter, nor shall ever see/That face of hers again (I.i.264-266). He cannot see far enough into the future to understand the consequences of this action. Ironically, he later discovers that Cordelia is the only daughter he wants to see, asking her to forget and forgive (IV.vii.85). By this time, he has finally started to gain some direction, and his vision is cleared, but it is too late for his life to be saved. Throughout this play, Shakespeare is saying that the world cannot truly be seen with the eye, but with the heart. The physical world that the eye can detect can accordingly hide its evils with physical attributes, and thus clear vision cannot result from the eye alone. Lear's downfall was a result of his failure to understand that appearance does not always represent reality.
