In The Stranger, the theme of Absurdism is central to the narrative and the character of Meursault. Absurdism, a philosophy that suggests life is inherently meaningless and the universe indifferent, is embodied in Meursault's actions and outlook. He is detached from societal norms and expectations, showcasing a life lived without seeking inherent meaning or purpose. Through Meursault, Camus illustrates the conflict between humanity's desire for significance and the indifferent universe, ultimately suggesting that individuals must create their own meaning within this absurd existence.

Meursault's reaction to his mother's death exemplifies Absurdism. The novel opens with the line, "Mother died today. Or, maybe, yesterday; I can’t be sure." This detachment highlights his indifference to societal expectations of mourning. Meursault's lack of emotional response underscores the absurdity of searching for meaning in death, a natural and inevitable part of life. His refusal to conform to societal norms of grief reflects the absurdist belief that traditional values and emotions are irrelevant in an indifferent universe.

His relationships further illustrate Absurdism. With Marie, Meursault engages in a physical relationship devoid of deeper emotional connection. When asked if he loves her, he responds, "I told her it didn't mean anything but that I didn't think so." This indifference to romantic norms reflects the absurdist idea that meaning is not inherent but constructed by individuals. Meursault's contentment with his life, despite societal disapproval, exemplifies Camus's view that one can find personal fulfillment by accepting life's absurdity and creating individual meaning.

Meursault's existential enlightenment occurs when he accepts the inevitability of death. He realizes, "I was sure about me, about everything, surer than he could ever be, sure of my life and sure of the death I had waiting for me." This acceptance of death as the only certainty aligns with Absurdism, which holds that life is a struggle against the inevitability of non-existence. Meursault's understanding that the universe is indifferent, and that he must live with this awareness, reflects the core of absurdist philosophy.

Ultimately, Meursault's journey in The Stranger is a reflection of Absurdism. His detachment from societal norms, his relationships, and his acceptance of death all illustrate the absurdist belief that life lacks inherent meaning. By embracing the absurdity of existence, Meursault finds a sense of peace and fulfillment, embodying Camus's philosophy that individuals must create their own purpose in an indifferent world.
