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.
