The narrative follows a naive young man named Candide who is expelled from a sheltered château and sent on a rapid succession of misadventures across continents. He repeatedly confronts his former tutor Pangloss's doctrine of philosophical optimism while witnessing war, natural disaster, exploitation, hypocrisy, and betrayal. Travel brings encounters with loyal companions, a cynical foil, a fabulously wealthy utopia, and episodes of rescue and loss that satirize received wisdom. Through brisk episodes and moral debate, the work undermines abstract optimism and concludes by favoring modest, practical labor and common sense over idle speculation.
