OK, here goes... I'm splitting it into two posts.
In many ways, it is the task of tragedy to teach the lessons of life that are the most difficult to swallow, and this is perhaps never made more evident than in Shakespeares King Lear. The play is particularly brutal concerning the concept of justice, not only in showing the characters flawed interpretations of it (especially the title characters), but also in questioning its very existence as a prominent force in our world. Despite the intense character interactions and layered emotions contained therein, King Lear manages to maintain a bleak and desolate landscape due almost entirely to the characters inability to cope with a world devoid of justice. The problems in the common ideas of justice that are brought to the forefront in Shakespeares work are universal in their scope, so it is not altogether surprising that they have been revisited many times in the works of many artists long after the 17th century. Among the most prominent of those artists are the rock musicians Radiohead. Their masterwork OK Computer, and particularly the two songs Paranoid Android and Karma Police, are the most important examples of this Shakespearean influence. In both lyrical themes and musical imagery, Radioheads work on these two pieces mirrors the harsh themes of justice that were presented so long ago in Shakespeares King Lear.
One of the plays most interesting comments on justice is that some humans seem to have a very poor idea of what constitutes justice in the first place. For the most part, Shakespeare chooses to show this lack of a correct sense of justice through the character of Lear, and he wastes no time in developing this theme. The very first scene depicts Lear dividing his kingdom to his daughters and their husbands, and he has decided that the best way to determine their inheritances is to have each of his daughters give a speech about how much they love him. While his older daughters, Goneril and Regan, give him the flattering answers he is looking for, Cordelia gives him the only truly loving answer: Unhappy that I am, I cannot heave / my heart into my mouth. I love your majesty / according to my bond, no more no less (William Shakespeare, King Lear, Penguin Books, 1.1.91-93). Of course, Lear is displeased with Cordelias answer, and his unjust anger is the primary motive force for the rest of the plays events. Because of this event, Lear disowns the only daughter that loved him, Goneril and Regan conspire together to take Lears kingdom away, and Lear is driven away in a storm of his own madness. In this storm, both mental and physical, Lear finds himself reduced from his previously lofty state, and is presented with an opportunity to improve his sense of justice. Indeed, it appears he understands this, as he says, Take physic, pomp; / expose thyself to feel what wretches feel, / that thou mayst shake the superflux to them / and show the heavens more just (3.4.35-38). Lear is making steps forward, but one doesnt have to wait even 50 more lines before Lear shows that he hasnt learned his own lesson. As Lear, Kent, and the Fool come upon one of the aforementioned poor wretches in the person of Edgar (disguised as poor Tom), Lear ignores the beggars problems, projecting onto him his own difficulties with filial ingratitude. Even though Kent tells Lear that Edgar has no daughters, the fallen king still cannot get past his own suffering to see that of others. As Lear slowly finds his way out of the storm, however, he shows some signs that he might be beginning to understand justice, through statements such as this one to the Earl of Gloucester: See how yond justice / rails upon yond simple thief (4.6.151-152). The best indication that Lears confusion with justice is clearing is his reaction to his reunion with Cordelia he recognizes the fault in his judgment at the beginning of the play, and displays a real fathers love for a child.
Lears trouble with the conception of justice is mirrored quite closely in the lyrics of Radiohead, particularly in Paranoid Android and Karma Police. In fact, both song titles give a hint to the connections: Lear is in many ways a paranoid man, and his sense of justice is comparably silly to the concept of karma, and police that must enforce it. The opening lines of Karma Police get right to the (ironic) point: Karma police, arrest this man he talks in maths, he buzzes like a fridge and hes like a detuned radio/Karma police, arrest this girl her Hitler hairdo is making me feel ill and we have crashed her party (Radiohead, OK Computer, Capitol Records, track 6). Lears fickle and self-serving sense of justice emerges clearly -- the karma police are not summoned to punish for any real evil acts. They only come for those that the narrator finds displeasing at that particular time, because of Hitler hairdos and talking in maths. The song ends, however, with the repetition of the lines, Phew, for a minute there, I lost myself, seeming to indicate that, like Lear, the narrator is not hopelessly confused (6). Paranoid Android echoes this theme, only much more violently. While the lyrics here are less transparent, they still give a vivid image of a sense of justice gone horribly wrong, with phrases like the power-hungry When I am king you will be first against the wall/With your opinion which is of no consequence at all(track 2) and especially with the horrific You dont remember, you dont remember, why dont you remember my name?/Off with his head, man, off with his head, (2) which is further amplified by sudden, atonal guitar riffs. The two songs ably display not only Lears impaired view of what is good and just and what is not, but also show the violent revenge that can result from such a malady. Lear shows us with his hasty, vengeful disowning of the loving Cordelia, who he calls a wretch whom Nature is ashamed / almost t acknowledge hers at the beginning of the play, that the emotions of the songs are only too fitting (1.1.217-218).
