Family-One of the major themes in the novel is family. Throughout the novel, the plot discusses how the family lives before and after the pearl. It is constantly the focus of the plot and many of the decisions are based on what would be best for the family. For example, the first thing that Kino desires to do with the money from the pearl is to give his wife and Coyotito a better life. This money would pay for Coyotito’s education, better clothes, and better protection. Later, Kino also demonstrates devotion to his family by not selling to the pearl dealer. The second buyer was trying to get the pearl for less than it was worth, but Kino, with his family in mind, declined to search for a better deal. He always has his family in mind, whether it leads to warmth and happiness or destruction. It was the reason Kino got the pearl and, eventually, the reason why he threw it back into the ocean.
Good and Evil -One of the biggest themes in this novel is the one between good and evil. This theme is displayed in other themes as well and it is shown from the beginning to the end. In the beginning, Kino lives a life of simplicity and happiness but when he discovers the pearl, he believes that good will come from it. However, a sense of evil accompanies it. After that, Kino and his family were in a constant battle against evil to preserve the good that they enjoyed before.
Paradox -The theme of paradoxes is displayed through Kino’s desires. Once Kino discovers the pearl, he begins to dream about what could come from this fortune as greed fills his head, but as he tries to carry out this plan, the good wealth also brings destruction to his family as he treats Juana poorly and is abusive. Though Kino desires good for his family, there is a paradox of an evil reality that he does not want. Kino tries to “avoid life’s inevitable tension” between these two but he finds that he cannot separate the good and the evil. In the end, the finding of the great prize causes him to lose another, his son.
Perseverance -The theme of perseverance is demonstrated by many characters, but mainly Kino. Before he found the pearl, he was a noble and a very determined person who sought fortune for his family. After he finds it, he is hoping to find it in a different way. Because Kino believes that this would save his family, he persists “though many obstacles” that accompany the pearl. He perseveres to keep the pearl but, in the end, it was not worth keeping.
