Looking back over the history of humanity, there is a well-known pattern of barbaric and aggressive behavior inherent in human beings. The desire to conquer and control one's environment has been proven to exist in human nature. Even if man's conscience manages to keep these instincts under control, if provoked they can lash out. Often, when faced with adversity, human beings tend to regress and lose their sense of rationality, giving rise to the emergence of their "id" personality. According to Adam Roberts' analysis of the unconscious mind, "the id functions outside the realms of logic or reasonableness, it just wants, and doesn't care how or why" (Roberts 56). Therefore, the “id” constitutes the subconscious of an individual's consciousness from which all primitive desires and impulses arise. It is not reachable by conscious thought, but it influences all human actions. The primal instinct inherent in man has been demonstrated historically as well as in written works of literature. These documented accounts and fictional writings shed light on a dark and intrinsic element of man's consciousness. In the literary works Lord of the Flies and Night, the characters are exposed to adverse conditions that prevail over rationality and evoke their innate desire for survival by resorting to ferocity and violence. William Golding's Lord of the Flies exemplifies man's ability to reveal his innate primordial nature. when there is a breakdown of social order and a thirst for power. The characters in his novel portray the monstrosity of the evil that dwells in human beings. For example, Kunwar's analytical essay on Golding's novel states: "Although the boys find themselves in a place far from corruption, a place without outside influences... middle of paper... survival with ferocity." . In man's quest for survival, these primal desires give rise to violence against the weak and oppressed. As a result, his rationality is called into question and a darker, more deeply rooted side of his nature begins to manifest. Throughout history, violence between men has shaped the world we live in through wars, political protests or social conflicts. Unfortunately, this is a factor of human nature that resides in all individuals and cannot be controlled or avoided. Not only have these events of human inhumanity been documented, but they have also become the underlying theme of many well-known literary works. Both Golding and Wiesel shed light on the immorality of humanity's actions by subjecting them to intense scrutiny, leaving the reader to wonder how humans are capable of hurting and killing each other so callously..
