Existential themes explore fundamental questions about human existence, such as the meaning of life, freedom, and the nature of reality. These themes often address feelings of anxiety, absurdity, and isolation that arise from the human condition. Philosophers like Jean-Paul Sartre and Albert Camus have examined how individuals confront these challenges and seek personal meaning in a seemingly indifferent universe. In literature and art, existential themes manifest through characters who grapple with their identity and purpose. Works like Franz Kafka's "The Metamorphosis" and Samuel Beckett's "Waiting for Godot" illustrate the struggle against existential despair and the search for authenticity. These narratives encourage reflection on the choices we make and the lives we lead.
