Just as everyone has the potential for evil within themselves, we too have the potential for true goodness.
In many literary works the author attempts to exemplify the evil which lies within by showing many characters which have been, or are being overcome by their inner darkness.
Marlow, who defeats his evil, and gains self-knowledge, and Kurtz, who is defeated by his darkness and falls prey to its wrath.
In William Golding's Lord of the Flies the author points out how easily people can be over taken by the darkness, how the potential for good can be destroyed by the evil, but ideally how good will triumph.
At first, everyone is excited about living on such a fantastic island filled with flowers, fruit, and swimming pools.
It is apparent that Ralph adores the island when, “…In the novel Heart of Darkness by Joseph Conrad we see how Marlow's journey into his ultimate evil, into his inner self, can be a positive experience.By contrasting Marlow with Kurtz, who represents the absolute evil, we can see the two products of an inner evil which has emerged.He feels that civility and order, although the ideal route, was going to be crushed, and with it him: "We can't do this, the savages, they would crush us" (Golding 54).It is quite obvious how the potential evil in a group of young boys unavoidably arises due to the lack of restraint and order.In the beginning, human influence was starting to affect this uninhabited “Garden of Eden”.Ralph, the charismatic and newly elected leader of the young boys’ parliament, is absolutely committed to civilization and morality, and is determined to make sure the boys survive and be rescued.That is, when one's darkness appears, one must learn from this experience how he or she can prevent similar results from occurring in the future.It is ultimately through self-knowledge that we gain the power to defeat our inner darkness, and all of its elements.When people lack the aspect of civility in their lives they too will lack the restraints and barriers it has on one's inner evil.Civility, in essence, provides the basic structure for good.
