 Camus’s graduate thesis at the University of Algiers sympathetically explored the relationship between Greek philosophy and Christianity, specifically the relationship of Plotinus to Augustine (Camus 1992). Nevertheless, his philosophy explicitly rejects religion as one of its foundations. Not always taking an openly hostile posture towards religious belief—though he certainly does in the novels The Stranger and The Plague—Camus centers his work on choosing to live without God. Another way to understand Camus’s philosophy is that it is an effort to explore the issues and pitfalls of a post-religious world.
