Themes are the fundamental and often universal ideas explored in a literary work.
Self-Interest versus Love
On the surface, the main difference between the Christian characters and Shylock appears to be that the Christian characters value human relationships over business ones, whereas Shylock is only interested in money. The Christian characters certainly view the matter this way. Merchants like Antonio lend money free of interest and put themselves at risk for those they love, whereas Shylock agonizes over the loss of his money and is reported to run through the streets crying, “O, my ducats! O, my daughter!” (II.viii.15). with these words, he apparently values his money at least as much as his daughter, suggesting that his greed outweighs his love. However, upon closer inspection, this supposed difference between Christian and Jew breaks down. When we see Shylock in Act III, scene I, he seems more hurt by the fact that his daughter sold a ring that was given to him by his dead wife before they were married than he is by the loss of the ring’s monetary value. Some human relationships do indeed matter to Shylock more than money. Moreover, his insistence that he has a pound of flesh rather than any amount of money shows that his resentment is much stronger than his greed. Just as Shylock’s character seems hard to pin down, the Christian characters also present an inconsistent picture. Though Portia and Bassanio come to love one another, Bassanio seeks her hand in the first place because he is monstrously in debt and needs her money. Bassanio even asks Antonio to look at the money he lends Bassanio as an investment, though Antonio insists that he lends him the money solely out of love. In other words, Bassanio is anxious to view his relationship with Antonio as a matter of business rather than of love. Finally, Shylock powerfully argues that Jews are human beings just as Christians are, but Christians such as Antonio hate Jews simply because they are Jews. Thus, while the Christian characters may talk more about mercy, love, and charity, they are not always consistent in how they display these qualities.
The Divine Quality of Mercy
The conflict between Shylock and the Christian characters comes to a head over the issue of mercy. The other characters acknowledge that the law is on Shylock’s side, but they all expect him to show mercy, which he refuses to do. When, during the trial, Shylock asks Portia what could possibly compel him to be merciful, Portia’s long reply, beginning with the words, “The quality of mercy is not strained,” clarifies what is at stake in the argument (IV.i.179). Human beings should be merciful because God is merciful: mercy is an attribute of God himself and therefore greater than power, majesty, or law. Portia’s understanding of mercy is based on the way Christians in Shakespeare’s time understood the difference between the Old and New Testaments. According to the writings of St. Paul in the New Testament, the Old Testament depicts God as requiring strict adherence to rules and exacting harsh punishments for those who stray. The New Testament, in contrast, emphasizes adherence to the spirit rather than the letter of the law, portraying a God who forgives rather than punishes and offers salvation to those followers who forgive others. Thus, when Portia warns Shylock against pursuing the law without regard for mercy, she is promoting what Elizabethan Christians would have seen as a pro-Christian, anti-Jewish agenda. The strictures of Renaissance drama demanded that Shylock be a villain, and, as such, patently unable to show even a drop of compassion for his enemy. A sixteenth-century audience would not expect Shylock to exercise mercy—therefore, it is up to the Christians to do so. Once she has turned Shylock’s greatest weapon—the law—against him, Portia has the opportunity to give freely of the mercy for which she so beautifully advocates. Instead, she...
