Albert Camus played a crucial role in shaping existential philosophy through his exploration of the absurd, freedom, and the human condition. His seminal works, such as The Stranger and The Myth of Sisyphus, challenge readers to confront the inherent meaninglessness of life and the necessity of creating personal meaning. Camus emphasized the importance of rebellion against the absurd, asserting that individuals must embrace their freedom and choices despite existential despair. His philosophical inquiries contributed to the broader discourse on existentialism, influencing later thinkers and writers, particularly in relation to morality and authenticity in an often indifferent universe.
