Absurdism is the philosophical theory that the universe is irrational and meaningless. It states that trying to find meaning leads people into conflict with a seemingly meaningless world. This conflict can be between rational humanity and an irrational universe, between intention and outcome, or between subjective assessment and objective worth, but the precise definition of the term is disputed. Absurdism claims that, due to one or more of these conflicts, existence as a whole is absurd. It differs in this regard from the less global thesis that some particular situations, persons, or phases in life are absurd.
Various components of the absurd are discussed in the academic literature, and different theorists frequently concentrate their definition and research on different components. On the practical level, the conflict underlying the absurd is characterized by the individual's struggle to find meaning in a meaningless world. The theoretical component, on the other hand, emphasizes more the epistemic inability of reason to penetrate and understand reality. Traditionally, the conflict is characterized as a collision between an internal component of human nature, and an external component of the universe. However, some later theorists have suggested that both components may be internal: the capacity to see through the arbitrariness of any ultimate purpose, on the one hand, and the incapacity to stop caring about such purposes, on the other hand. Certain accounts also involve a metacognitive component by holding that an awareness of the conflict is necessary for the absurd to arise.
