Best of All Possible Worlds from Candide?

In Voltaire's "Candide," the concept of the "best of all possible worlds" stems from the character Pangloss, who believes that everything in the world is for the best because God created it that way. This idea is challenged throughout the novel as Candide experiences numerous hardships and tragedies. Ultimately, the novel critiques blind optimism and highlights the realities of suffering and human experiences.
