Existentialist thought is a philosophical movement that emphasizes individual freedom, choice, and the search for meaning in a seemingly indifferent universe. It suggests that people are responsible for creating their own values and purpose, rather than relying on external authorities or societal norms. Key figures in this movement include Jean-Paul Sartre and Simone de Beauvoir, who explored themes of existence, authenticity, and the human condition. At its core, existentialism grapples with the idea that life can be absurd and chaotic, yet individuals have the power to shape their own destinies. This philosophy encourages self-reflection and personal responsibility, urging people to confront their own existence and make meaningful choices in a world that often feels uncertain.
