Absurdism is a philosophical and literary concept that identifies the fundamental conflict between humanity's inherent tendency to seek meaning, value, and rational order in life and the simultaneous discovery of the universe's irrationality and meaninglessness. It investigates the human condition arising from this irreconcilable tension, characterized by themes of futility, existential angst, and the breakdown of traditional systems of belief and logic. Its significance lies in its influence on 20th-century thought and art, particularly in literature and theatre, as a framework for exploring the confrontation with a silent, indifferent cosmos.
