Existential philosophy is a branch of thought that focuses on individual existence, freedom, and choice. It emphasizes the importance of personal experience and the subjective nature of reality. Existentialists believe that individuals must create their own meaning in a world that can often seem chaotic or indifferent. Key figures in this movement include Jean-Paul Sartre and Simone de Beauvoir. This philosophy often explores themes such as anxiety, absurdity, and authenticity. It challenges people to confront their own existence and the responsibilities that come with freedom. Existentialism has influenced various fields, including literature, psychology, and theology, encouraging deeper reflection on the human condition.
