Albert Camus’s existentialist philosophy was profoundly informed by his personal experiences, including growing up in a troubled family environment in Algeria and facing the challenges of absurdism in life. His experiences during World War II and working in the French Resistance further deepened his understanding of human suffering and the search for meaning. Camus's focus on individual freedom amidst a chaotic world emphasizes the necessity of personal responsibility, as reflected in works like "The Myth of Sisyphus," where he explores the struggle against absurdity and advocates for embracing life’s challenges.
