Knowledge in Lord of the Flies is more about awareness and wisdom than anything else. There are certain important truths that some characters are privy to and others are not. The characters that are “in the know” seem to have possession of these truths innately, as though by some spiritual means. The boys left in the dark are simply at odds with their more savvy counterparts; they fail to understand these wiser children (like Simon) and instead of trying to learn from them, violently lash out at them. It seems then, that the wisest boys are sacrificed, made martyrs for the very key knowledge they possess. The irony is that, by killing these knowing boys, the naïve characters are keeping themselves in the dark.
In Lord of the Flies, ignorance always brings destruction.
