Absurdism

Absurdism is the philosophical theory that life in general is absurd. This implies that the world lacks meaning or a higher purpose and is not fully intelligible by reason. The term "absurd" also has a more specific sense in the context of absurdism: it refers to a conflict or a discrepancy between two things but there are several disagreements about their exact nature. These disagreements have various consequences for whether absurdism is true and for the arguments cited in favor and against it. Popular accounts characterize the conflict as a collision between rational man and an irrational universe, between intention and outcome, or between subjective assessment and objective worth. An important aspect of absurdism is its claim that the world as a whole is absurd. It differs in this regard from the uncontroversial and less global thesis that some particular situations, persons, or phases in life are absurd.
