Existentialism is a philosophical movement that focuses on individual freedom, choice, and the search for meaning in a seemingly indifferent universe. It emphasizes that people are responsible for creating their own values and purpose, rather than relying on external sources like religion or society. Key figures in this movement include Jean-Paul Sartre and Simone de Beauvoir, who explored themes of existence, freedom, and the human condition. At its core, existentialism encourages individuals to confront the absurdity of life and embrace their freedom to make choices. This philosophy often highlights feelings of anxiety and alienation, suggesting that these experiences can lead to personal growth and authenticity. Through this lens, life becomes a canvas for self-discovery and meaningful action.
