Ralph is the athletic, charismatic protagonist of Lord of the Flies. Elected the leader of the boys at the beginning of the novel, Ralph is the primary representative of order, civilization, and productive leadership in the novel. While most of the other boys initially are concerned with playing, having fun, and avoiding work, Ralph sets about building huts and thinking of ways to maximize their chances of being rescued. For this reason, Ralph’s power and influence over the other boys are secure at the beginning of the novel. However, as the group gradually succumbs to savage instincts over the course of the novel, Ralph’s position declines precipitously while Jack’s rises. Eventually, most of the boys except Piggy leave Ralph’s group for Jack’s, and Ralph is left alone to be hunted by Jack’s tribe. Ralph’s commitment to civilization and morality is strong, and his main wish is to be rescued and returned to the society of adults. In a sense, this strength gives Ralph a moral victory at the end of the novel, when he casts the Lord of the Flies to the ground and takes up the stake it is impaled on to defend himself against Jack’s hunters.

In the earlier parts of the novel, Ralph is unable to understand why the other boys would give in to base instincts of bloodlust and barbarism. The sight of the hunters chanting and dancing is baffling and distasteful to him. As the novel progresses, however, Ralph, like Simon, comes to understand that savagery exists within all the boys. Ralph remains determined not to let this savagery -overwhelm him, and only briefly does he consider joining Jack’s tribe in order to save himself. When Ralph hunts a boar for the first time, however, he experiences the exhilaration and thrill of bloodlust and violence. When he attends Jack’s feast, he is swept away by the frenzy, dances on the edge of the group, and participates in the killing of Simon. This firsthand knowledge of the evil that exists within him, as within all human beings, is tragic for Ralph, and it plunges him into listless despair for a time. But this knowledge also enables him to cast down the Lord of the Flies at the end of the novel. Ralph’s story ends semi-tragically: although he is rescued and returned to civilization, when he sees the naval officer, he weeps with the burden of his new knowledge about the human capacity for evil.

The strong-willed, egomaniacal Jack is the novel’s primary representative of the instinct of savagery, violence, and the desire for power—in short, the antithesis of Ralph. From the beginning of the novel, Jack desires power above all other things. He is furious when he loses the election to Ralph and continually pushes the boundaries of his subordinate role in the group. Early on, Jack retains the sense of moral propriety and behavior that society instilled in him—in fact, in school, he was the leader of the choirboys. The first time he encounters a pig, he is unable to kill it. But Jack soon becomes obsessed with hunting and devotes himself to the task, painting his face like a barbarian and giving himself over to bloodlust. The more savage Jack becomes, the more he is able to control the rest of the group. Indeed, apart from Ralph, Simon, and Piggy, the group largely follows Jack in casting off moral restraint and embracing violence and savagery. Jack’s love of authority and violence are intimately connected, as both enable him to feel powerful and exalted. By the end of the novel, Jack has learned to use the boys’ fear of the beast to control their behavior—a reminder of how religion and superstition can be manipulated as instruments of power.

Whereas Ralph and Jack stand at opposite ends of the spectrum between civilization and savagery, Simon stands on an entirely different plane from all the other boys. Simon embodies a kind of innate, spiritual human goodness that is deeply connected with nature and, in its own way, as primal as Jack’s evil. The other boys abandon moral behavior as soon as civilization is no longer there to impose it upon them. They are not innately moral; rather, the adult world—the threat of punishment for misdeeds—has conditioned them to act morally. To an extent, even the seemingly civilized Ralph and Piggy are products of social conditioning, as we see when they participate in the hunt-dance. In Golding’s view, the human impulse toward civilization is not as deeply rooted as the human impulse toward savagery. Unlike all the other boys on the island, Simon acts morally not out of guilt or shame but because he believes in the inherent value of morality. He behaves kindly toward the younger children, and he is the first to realize the problem posed by the beast and the Lord of the Flies—that is, that the monster on the island is not a real, physical beast but rather a savagery that lurks within each human being. The sow’s head on the stake symbolizes this idea, as we see in Simon’s vision of the head speaking to him. Ultimately, this idea of the inherent evil within each human being stands as the moral conclusion and central problem of the novel. Against this idea of evil, Simon represents a contrary idea of essential human goodness. However, his brutal murder at the hands of the other boys indicates the scarcity of that good amid an overwhelming abundance of evil.
